Welcome to the Year of the Snake Challenge

Special Note: This is the second ever GFN challenge and probably the last, so for those who are not familiar with GFN we are searching for exceptionally large prime numbers. If a prime is found during the challenge it will be the 11th largest prime number ever found.

A 13 day Challenge celebrating the start of a new year is being offered on PrimeGrid's Generalized Fermat Number (GFN) application. Only SHORT Work Units may be used in this challenge. To participate in the Challenge, please select only the Generalized Fermat Prime Search project and also select Short tasks in your PrimeGrid preferences section. Although the World Record units can also be completed within 13 days, these do not count! You may leave the Block Size setting at 0.

The challenge will start on 4 January 2013 18:00 UTC and end 13 days later on 17 January 2013 18:00 UTC.

Important: The deadline for these WUs is significantly longer than three days, so make sure your computer returns the WUs before the end of the challenge.


Application Builds


    Application builds are available for 64 bit CPUs (with a 64 bit OS), OR for double precision Nvidia GPUs (The GPU apps are 32 bits and will run on 32 or 64 bit CPUs and OSs.) Apps are available for Linux, Windows and MacIntel.

    Unfortunately, ATI/AMD GPUs can not be used for this challenge, nor can any Nvidia GPU that lacks double precision hardware. Specifically, the GPU must have Compute Capability 1.3. Please see the List of Compatible GPUs for more details.


A Cautionary Reminder


    ATTENTION: The primality programs Genefx64 (CPU) and GeneferCUDA (GPU) are both computationally intensive; so, it is vital to have a stable system with good cooling. They do not tolerate "even the slightest of errors." Please see this post for more details on how you can "stress test" your CPU, and please see this post for tips on running GFN on your GPU successfully.

    As with all number crunching, excessive heat can potentially cause permanent hardware failure. Please ensure your cooling system is sufficient.

    If you have never run GeneferCUDA before, please read these tips. GeneferCUDA stresses a GPU more than any other program I've seen and is incredibly intolerant of overclocking. It is strongly suggested that you run at least one (Short) Work Unit before the challenge to make sure your computer can handle it. Note that "Overclocking" includes GPUs that come overclocked from the factory, and lowering clock rates to the reference speeds is sometimes necessary. In the case of one particular GPU, the GTX 550 Ti, lowering the memory clock below the reference speed is often necessary.

    WU's will take ~10 hours on a GTX 580 GPU and about 2 to 3 days on the fastest CPU core. A GTX 680 will be slower than a GTX 580 for this application. On my computer (GTX 460 & C2D Q6600), which is more of an "average" computer and certainly not the fastest, a Work Unit takes about 20 hours on the GPU and 5 to 7 days on the CPU.

    If your CPU is highly overclocked, please consider "stress testing" it. Overclocking your GPU not recommended at all for GeneferCUDA. Sieving is an excellent alternative for computers that are not able to run Genefer. :)


    Please, please, please make sure your machines are up to the task.


Time zone converter:


    The World Clock - Time Zone Converter

    NOTE: The countdown clock on the front page uses the host computer time. Therefore, if your computer time is off, so will the countdown clock. For precise timing, use the UTC Time in the data section to the left of the countdown clock.

Scoring Information


    Scores will be kept for individuals and teams. Only work units issued AFTER 4 January 2013 18:00 UTC and received BEFORE 17 January 2013 18:00 UTC will be considered for credit. For scoring, we will use BOINC Credits which are based on the b and n values (b^2^n+1).

    Therefore, each completed WU will earn a unique score based on its b value ('n' will be the same for all Work Units). The higher the b, the higher the score. A quorum of 2 is NOT needed to award Challenge score - i.e. no double checker. Therefore, each returned result will earn a Challenge score. Please note that if the result is eventually declared invalid, the score will be removed.

What to expect at Challenge start


    The server always gets hit hard at the beginning of the Challenge. However, GFN tasks are quite long so we don't expect a heavy load. Nevertheless, a few hours before the start (4 January 2013 18:00 UTC) "max cache" will be dropped. Additionally, "max to send" will be dropped. Anyone attempting to request more will be met with "max cache" messages.

    We'll raise the front page buffer before the start of the Challenge. These settings will be adjusted as necessary. Afterwards, as conditions allow, we'll raise "max cache". We'll continue to increase "max cache" when the server can handle it.

    This method allows the greatest opportunity for the most clients to get work. Even if it's just 1 task for the first few minutes, at least the client is crunching. Past Challenges have shown that clients have an excellent chance to reach "max cache" before their first task is complete. We expect the same this time.

Strategies for starting the Challenge


    Depending on a variety of factors, different strategies work for different users. Here are just a few to consider:

  • large farm, user can be present at start
    -Set Computer is connected to the Internet about every to 0 days
    -Set Maintain enough work for an additional to 0 days
    -Change PrimeGrid preferences to a fast WU project such as PPS (LLR)
    -At Challenge start, update PrimeGrid preferences and only select the GFN (SHORT) project
    -At worse, you'll only be 1 PPS (LLR) WU late on each core starting the Challenge.
    -After all machines have work, increase Maintain enough work for an additional buffer
  • large farm, user NOT able to be present at start
    -Same connection settings as above
    -At earliest access to hosts after start, switch to the GFN (SHORT) project
  • a few computers, user can be present at start
    -Change PrimeGrid preferences and only select the GFN (SHORT) project
    -Set computers to "No New Tasks" for PrimeGrid
    -At Challenge Start, update computers to "Allow New Tasks"
  • a few computers, user NOT able to be present at start
    -same settings as "large farm, user NOT able to be present at start"

    NOTE: This presumes you have all other BOINC projects suspended.

At the Conclusion of the Challenge

    We kindly ask users "moving on" to ABORT their WU's instead of DETACHING, RESETTING, or PAUSING.

    ABORTING WU's allows them to be recycled immediately; thus a much faster "clean up" to the end of an LLR Challenge. DETACHING, RESETTING, and PAUSING WU's causes them to remain in limbo until they EXPIRE. Therefore, we must wait until WU's expire to send them out to be completed.

    Please consider either completing what's in the queue or ABORTING them. Thank you. :)

    For those of you who wish to continue to help with GFN sieving, we are still sieving n=22 (World Record Units), as well as the n=20 (short) range and n=21 (next short) range. Please see We need your help with GFN Sieving! for more information.

Minor detail that might not even affect anyone:

There's still a VERY small number of the older, smaller, n=19 WUs still bouncing around. As of right now, there's 9 of them that haven't completed yet. It is possible that some may still be in progress during the challenge, and if they get returned with an error, they will be sent out again during the challenge.

Currently, this happens between 1 and 3 times per day, and the number is, of course, dropping.

If any of these get sent out during the challenge, they'll run about 3 to 4 times faster than the n=20 WUs, but the credits/hour will be identical to the longer WU.

EDIT: Down to 8.

Why such a sudden race? The Year of the Snake doesn't appear to start until February 10.

The first challenge is longer then marathon. Two weeks on GPUs... I know, Michael loves GFN, but this subproject pays very little, especially in such a difficult challenge. Could you give more points for this challenge? ;)

Robert,

The challenge is as long as it is so CPU users can participate. Even if we had the AVX version of Genefer available (realistically, that's probably a few months away), we would still want as many people to be able to participate as possible, so the challenge needs to be long enough for people with older CPUs to participate. As it is, people who have neither a double precision Nvidia GPU nor a 64 bit CPU with a 64 bit OS can't participate, and even that is unfortunate. We don't want to also exclude the large percentage of people who can use a 64 bit CPU, especially because the short GFN project is very popular on CPUs.

this pays not littlle, here my Test:

My graphic card: Nvidia Geforce 660 GTX TI

You see 3 tasks

425797667 311755972 28 Dec 2012 | 3:01:04 UTC 29 Dec 2012 | 15:53:59 UTC 44,332.98 822.17 23,064.17 Genefer v1.07 (cuda32_13)

Depends what you are comparing it with. This is my GTX660Ti doing GPUGrid ~42k seconds long tasks:

6277458 4006000 30 Dec 2012 | 16:49:43 UTC 31 Dec 2012 | 6:49:38 UTC Completed and validated 41,298.22 41,269.73 135,150.00 Long runs (8-12 hours on fastest card) v6.16 (cuda42)

I know, it is a different project etc. , but all in all it is 24k vs. 135k.

The scoring is based on the time a task takes on a CPU, if they raise it to 100k instead of 24k then everybody would only run genefers with CPU and nobody would run any other LLR sub-projects anymore, which would be a shame. Actually I think the scoring is even a bit higher then most LLR projects. Of course sieving with a GPU gives way more points, but with genefer you have a chance to find a top 10 prime!

Edit:
Is it possible to let the clean up of this challenge be done only by PCs which have low error rates and decent return times? Otherwise the clean up of this challenge will take maybe more than a month? I now have a GFN task running, that has been sent out 9 times and only reported once. And this is not an isolated case, I see a lot of tasks with _4 or higher.

Depends what you are comparing it with. This is my GTX660Ti doing GPUGrid ~42k seconds long tasks:



Don't forget the GPUGrid "cheats" by awarding a 50% bonus for returning tasks early. That's very important to their work, and I certainly don't mind that they do this, but if you're comparing apples to apples you need to remove that bonus. (Don't get me wrong, I'm a big fan of GPUGrid and did a fair amount of crunching for them in the past. It's just not fair to use them in a credit comparison because of the bonus they provide.)

There's a specific amount of credit a project is supposed to hand out for a given amount of work, and we (and most other projects) *try* to come as close to that as we can. If projects handed out credit arbitrarily, credit would become grossly inflated and meaningless.

Actually, the scoring is based upon how fast my GTX 460 can run the tasks. :) Genefer is very predictable, however, so it scales nicely to faster and slower GPUs, and to CPUs.

Figuring out the overall credit rate was a difficult process.


if they raise it to 100k instead of 24k then everybody would only run genefers with CPU and nobody would run any other LLR sub-projects anymore, which would be a shame.


That was a consideration. Credits/hour with Genefer shouldn't be wildly different than with LLR, in either direction, or many people would flock to one and ignore the other.

Of course sieving with a GPU gives way more points, but with genefer you have a chance to find a top 10 prime!


In my opinion (which is just one of many) sieving should have higher rates because it doesn't offer the chance to find a prime.

Edit:
Is it possible to let the clean up of this challenge be done only by PCs which have low error rates and decent return times?

Error rates with the short tasks aren't all that bad. Besides, errors aren't what slows down the validation -- it's hosts that go MIA and never return the tasks and give you a 19 day delay that hurt you. Errors generally occur very quickly, so the delay isn't that large.

Anyway, no. there isn't a really easy way to send tasks to good hosts. We'll just have to be patient.

While we're talking, I'd like to remind everyone that doesn't normally run GFN on their GPUs that GeneferCUDA generally doesn't work correctly with overclocking. This includes overclocking that was done at the factory!!!

It sucks to crunch for a lot of hours only to have the task fail validation.

If you're new to the sub-project, I strongly recommend reducing your GPU clock rates to stock clock speed -- which may be lower than the clock speeds the GPU came with.

Note that this only applies to GPUs. CPUs you can overclock as you normally would for LLR.

Thanks Michael, for expanding (and correcting) on my explanation. I agree that credits should be fair and the effect of credits should not be underestimated. For example Milkyway@home had a weekend with double credits to compensate for their downtime and serverproblems some time ago, the output (both in credits and Gflops) of the project exploded in that weekend. This was of course good for Milkyway@home, but it also had an unwanted side-effect to drew people from other projects that weekend, myself included.

They apply 50% bonus to every task returned within 24 hours, so with a little knowledge you get it every time. Just avoid long task if your GPU is not suitable for them, and you get the bonus. Hard to call it is a bonus then. I would rather say, there could be punishment for late delivery ;-)

As of 12/31 there's only 3 left.

No good idea

In BoinC Manager, i have the setting: 0,00 days for tasks

If I need Genefer tasks, so come 25 of this.

the Challenge begins in 46 hours

I can do 3 tasks ( 3x12 hours )

please

one task is enough, if some body want to do more,when ready, then the next task

but 25 is to much,

and so give back 22 tasks, Thats be right ?

You got 25 tasks because BOINC doesn't always understand how long it will take to run a task.

Once you complete the first of the tasks, BOINC will increase its estimate of the run time of the GFN tasks and that should resolve the problem.

For now, feel free to abort those extra 22 tasks. The server won't care!

SHIFT is a number that tells the GPU how much work to do at one time. The higher the number, the more efficient the program is (faster and uses less CPU), but the more likely you are to get screen lag.

If you're not experiencing screen lag, leave the setting at 0, which will allow GeneferCUDA to choose the best setting. If you have bad screen lag, you can lower the SHIFT setting.

For the short WUs used in this challenge, GeneferCUDA will use SHIFT=7 on Windows which should work well for most people.

Long WUs use SHIFT=8 on Windows. I prefer to use SHIFT=7 for those because I get less lag. It takes 2 more hours to run using SHIFT=7, but that's ok because the total run time is over 10 days, so 2 hours isn't significant.

The default shift values are as follows: (challenge tasks are in RED, WR tasks are in BLUE)

Windows:
262144: 7
524288: 7
1048576: 7
2097152: 8
4194304: 8

Linux:
262144: 7
524288: 7
1048576: 8
2097152: 8
4194304: 9

Given that, let me ask the probably stupid but obvious follow-up question. If decreasing shift makes WUs slower, can we increase it to make them faster?

I'll generally assume the answer is no. But I also notice the value is different on Linux. Does that mean those using Windows can increase the value to the Linux value? Or that Linux computes faster overall?

I know this is getting to be a broken record sort of thing, but I don't know what I'm doing again....

I just changed my prefs to start grabbing the short GENEFER CPU tasks to test before the challenge. I'm running this box with 98% CPU usage. These tasks are expected to take over 3500 hours.

Hardware is quad-core i5 processor at 3.2ghz.

What do I need to fix here?

thanks,

Given that, let me ask the probably stupid but obvious follow-up question. If decreasing shift makes WUs slower, can we increase it to make them faster?


On Windows, the answer is most likely "no". For the most part, the numbers are set such that you get maximum performance at each N. It's sort of like approaching the speed of light -- you can't really go a whole lot faster once you're close to maximum.

I'll generally assume the answer is no. But I also notice the value is different on Linux. Does that mean those using Windows can increase the value to the Linux value? Or that Linux computes faster overall?


If anything, I suspect you get better performance under Windows, not Linux. GPUs are gaming devices, and Nvidia probably throws far more resources at the Windows side of the house.

I'm not really sure WHY there's a difference. It could be the drivers, the way the OS handles device calls, or something else. Whatever the reason, there's another concern on Linux that really doesn't seem to be a concern on Windows: CPU usage. With lower shift values, CPU usage goes up, and this is a bigger concern on Linux than on Windows. So the values may be higher in some cases to lower the CPU usage to reasonable levels.

That's how we came up with the default values. Get the lowest shift value that produces the maximum performance -- unless that produced very high CPU usage, in which case we raised the shift value to lower the CPU usage.

Of course, it's entirely reasonable that your results might vary from what we saw when doing our testing. And, of course, in the time since then new drivers, new GPUs, and new CPUs have all been released. It's certainly possible that you might find that a different value works better on your hardware. Or, like me, you might want to trade a little performance for better responsiveness and less screen lag.

There's a "-b2 N" flag that runs a series of benchmarks, at different SHIFT values, at a specific N value. You can use this to quickly determine the best SHIFT setting for you. If you enter the command "GeneferCUDA -b2 20" it will test the full range of SHIFT values, printing the benchmark speed for each one. If you monitor CPU usage and screen lag while this is running, you get a good picture of what works best for you. (20 is the number to use for the short WUs that will be running in the challenge, and 22 is for the World Record tasks.)

By the way, every time you increase SHIFT by 1 it doubles the amount of work done in each CUDA kernal. It's called SHIFT because the iteration counter is shifted to the left by this number of bits.

I know this is getting to be a broken record sort of thing, but I don't know what I'm doing again....

I just changed my prefs to start grabbing the short GENEFER CPU tasks to test before the challenge. I'm running this box with 98% CPU usage. These tasks are expected to take over 3500 hours.

Hardware is quad-core i5 processor at 3.2ghz.

What do I need to fix here?


I'm sure you know that those won't really take 4 months; the esitmates are just bad.

BOINC really gets messed up with all the different sub projects and there's no easy answer. What I do is try to never run different sub projects simultaneously. When I switch between projects, I either let BOINC slowly correct itself, or I go in and manually adjust it.

What you need to do is manually change the duration correction factor (DCF).

If you click on the PrimeGrid project in the Projects tab, and then hit the properties button, a window will pop up, and in that Window you will find the DCF for PrimeGrid. I'm guessing your machine can actually do those tasks in about 180 hours, so the DCF is about 20 times too high.

To manually correct it, completely shut down boinc, then open the client_state.xml file in a text editor. You'll find that file in the main BOINC data directory, which is usually C:\ProgramData\BOINC on Windows.

Look for a section that looks like this...

<project>
<master_url>http://www.primegrid.com/</master_url>
<project_name>PrimeGrid</project_name>
...
<duration_correction_factor>1.549128</duration_correction_factor>


There's the number you want to change. In your case, you can put the DCF in the correct ballpark by dividing whatever number you find there by 20. Save the file, and then restart your computer. That should do it.

Just be aware that if you're running a bunch of other subprojects, they can instantly push the DCF back up. DCF goes up instantly, but goes down slowly.

It's a big problem with BOINC.

I missed this the first time I read it. I just want to make sure you're aware that there's no way you'll be able to complete those tasks on a CPU before the challenge starts. I'm guessing that the fastest CPUs probably need 3 or 4 days for these. Even when we get the AVX version running, it will take close to two days on a fast i7 without HT. The current software takes more than twice as long.

To follow up on what Michael last said, if you want to score as best you can in the challenge, just "abort" the CPU units you're already running, assuming you grabbed them as a test and didn't plan to just run them without regard to the challenge. There's no shame in the "abort" button.

Two days, four results, look very good speed for me, and those numbers are huge compared to other projects :)

Those numbers look very good compared to a GTX 580!!!

The new code from Yves Gallot appears at first glance to be very impressive. There will be a nice speed increase even for CPUs without AVX. I'm personally very excited about the possibilities.

Is it OK to abort all GFN tasks just before the start of the challenge? On some projects when I abort a bunch of tasks (like turning my farm back on after several days powered off) I cannot get any work units for a while. Currently, I have set my profile to not get any new work but there are still a bunch of PrimeGrid tasks still running.

Thanks for looking!

It might depend on how many a "bunch" is. I doubt there will be a problem, because generally people don't have a lot of GFN tasks because they're huge. I can't imagine having enough GFN tasks on a single host to cause any "bad host" restrictions to occur.

I run GFN to prepare the snake challenge
GPU0 GTX 570 @732/1900 8h 43:27
GPU1 GTX 470 @607/1674 9h 58:23
GPU2 GTX 470 @607/1674 10h 53:42

Was just wondering... on your posted specs are those the shader clocks you have listed ie GTX 570@732/1900 where the 1900 is the shader? Only reason I ask is because if so then those are fairly over clocked settings but you are able to get the wu's to run.

HELP! I just checked my results and have nothing but errors
http://www.primegrid.com/results.php?userid=56128

No overclocking, no high temps, this should be working but it isnt. I am doing something wrong it seems. I have no problem with other tasks but all are erroring out!

I have never processed these task before and thought I would run a few before tomorrows start.

It's only your host with 3 gtx 460 (http://www.primegrid.com/results.php?hostid=185566).

stdr shows your clock is 1526. There are different versions of gtx 460 and most of them have lower clocks (1300 or 1350). Unless it a 460 v2, is is overclocked (factory overclock can still mess with GeneferCuda).

Try downclocking to stock (675/1350) and downclock the memory to 1800Mhz if it is higher.

Check stock clocks here: http://www.geforce.com/hardware/desktop-gpus/geforce-gtx-460/specifications

btw, you'll hardly finish any task before the challenge starts.

Only one of your computers is producing errors: the Core2Quad Q6700 with the GTX460. All the others are working fine.

This 460 is producing the "maxErr exceeded" error which is the typical error you get from overclocking.

This is from one of the tasks from that GTX 460:

GPU=GeForce GTX 460
Global memory=1073414144 Shared memory/block=49152 Registers/block=32768 Warp size=32
Max threads/block=1024
Max thread dim=1024 1024 64
Max grid=65535 65535 65535
CC=2.1
Clock=1526 MHz
# of MP=7
No project preference specified; using SHIFT=7


This is from my own GTX 460:

GPU=GeForce GTX 460
Global memory=1073414144 Shared memory/block=49152 Registers/block=32768 Warp size=32
Max threads/block=1024
Max thread dim=1024 1024 64
Max grid=65535 65535 65535
CC=2.1
Clock=1350 MHz
# of MP=7
No project preference specified; using SHIFT=7


Your GPU *is* overclocked. It probably come that way from the factory. Lowering the clock rates to stock speeds should help.

I have two eVga, one is 460x2 the other is single.

According to eVga precision X I am running 700/1800, 700/1800 and 763/1900. These were set by clicking on "default" and "apply:" for each of the 3 GPU SELECT tabs. I do not know where the task details came up with a clock speed of 1526 unless it added up the clocks ??

The same system shows NO errors on the other primegrid that I have been crunching for a year or so.

I will load that new driver 310 that just came out and see if that helps.

1526 = 763 doubled. Clocks you report as xxx/xxxx are core/memory. On Fermi cards, shaders are linked to core (unlike previous NVidia models) and are always double core clocks.

On the GTX 460, I have had no previous problems with wildly high overclocks crunching GFN (granted, I am using ASUS "TOP" models). I would advise to start by lowering you memory clocks to 1700 and see if that gets rid of the errors.

OK so the suggestion is to
(1) set gpu clock down to 675
(2) set memory down to 1800

I will do that. What bothers me is the previous results, PPS, all seemed to be good. There are no wingmen for those, so how does one know if they were really valid or not?

[EDIT] I think I know what may have been the problem. The "SYNC [X]" was originally checked and if (I am guessing) I changed the single gtx460 then precision X synch'ed the gtx460x2 to the singles higher values. I noticed that I had to uncheck SYNC before I could set each processor.

Anyway, I will run a few more hours and see if there is any more failures.

Thanks for all the help!

Genefer is very different from sieves. The results on the latter are fine.
There are several threads describing the issues of genefer with overclock, drivers, heat and other causes for errors. Oc is the easiest to solve. If downclocking memory to 1800 still causes errors, try 1700, as Scott suggested. Good luck

This is a bit off-topic, but...
First, the PPS sieve app tries to check that results are correct, but it's hard. Some WUs have no factors to check at all. If you've done dozens of PPS sieve WUs and none have failed, more than likely your GPU did them correctly.

The other difference is that PPS sieve doesn't use your GPU's memory much, while Genefer uses it so much that it can be memory bandwidth-limited. So I tend to think your GPU RAM overclock is more likely to be at fault than your shader overclock. But it may not be worth testing that hypothesis this close to the race.

What bothers me is the previous results, PPS, all seemed to be good. There are no wingmen for those, so how does one know if they were really valid or not


Excellent question.

First of all, as is noted, the sieves and Genefer are VERY different programs and use different parts of the GPU hardware. That explains the difference in the behavior.

As for the possibility of having errors in the sieve, rest assured, all is good.

The sieves' output is a list of factors that are found. There's two conceivable errors: a false positive, and a false negative.

A false positive is when the sieve generates a factor that really isn't a factor. The PrimeGrid server checks every factor that comes in from a host, so false positives will be detected and discarded. It's a very fast check on the server, and this prevents a false positive from erroneously removing a candidate number.

A false negative is when a factor should have been found, but wasn't. This error will not be detected -- but it's not that big of a problem. At worst, it means that a candidate number will eventually be checked by either LLR or Genefer instead of being removed by the more efficient sieve program. In practice, however, composite numbers often have many factors, so even if one factor was missed, the composite number can still be removed from the sieve file by a factor found in another sieve task. If that happens, there's nothing lost at all because of the error.

OK so the suggestion is to
(1) set gpu clock down to 675
(2) set memory down to 1800

I will do that. What bothers me is the previous results, PPS, all seemed to be good. There are no wingmen for those, so how does one know if they were really valid or not?

Genefer is very different from sieves. The results on the latter are fine.
There are several threads describing the issues of genefer with overclock, drivers, heat and other causes for errors. Oc is the easiest to solve. If downclocking memory to 1800 still causes errors, try 1700, as Scott suggested. Good luck

If you still have errors increase your GPUs fan speed to a much higher setting (Max it out if you can handle the fan noise). I have A/C pumped into my 460 and and I can run it at 975 clock/1950 shader - 1900 mem - voltage at 1.075 and temps only in the 40s C with only rare errors. So heat is a big reason for errors.

We think we have everything covered for the challenge:

The server time is correct, and should stay that way, so the challenge should start exactly on time.

WU purging is turned off so the challenge results won't vanish on us.

We're going to load a ton of work before the challenge so nobody runs out. Hopefully, anyway. There's a lot of black magic involved in keeping the server running at the start of a challenge. We're still discussing the details, but it will be done before 18:00 tomorrow.

The challenge scoring system should work correctly.

The hamsters have all been fed and are turning their wheels at warp speed.

40k takes about 8.5 hours on a GTX 570.
110k takes about 9.5 hours on a GTX 570.
So that means about 12% increase.

Yea, something's fishy. That's ~1/6th the total completed tasks for all of N=524288.

I checked with Mike, and the only thing fishy is BOINC ;)

A Work Unit is considered in progress if it has been generated and has at least one task ready to send to a user. It doesn't actually have to be out there for it to be "in progress". It could be made to only include units that are actually out there, but that would be a much more expensive query on the database.

Normally the difference isn't all that big, but with the giantic buffer for the challenge we're looking at a difference of about 12.5k. So in actuality there are about 3.6k tasks out there being crunched.

Yes, the changes some of you have noticed are in preparation for the challenge. The buffer of available tasks has been increased from 1000 to 25000. That, in turn required creating work units for those tasks, and once the work units are created they show up on the GFN stats page as "in progress".

Not only does it show ~16000 WUs as in progress now, but it also artificially raises the leading edge -- in this case up to about 110K.

This is not a new phenomena, nor is it specific to GFN. All of the sub-project status pages work like this, so the leading edge is always slightly inflated, depending on how large the buffer is for that sub-project.

The only thing that's changed is you guys are getting more observant. :)

The actual "leading edge", i.e., tasks that are really being worked on, is just above 40K right now. I expect that to change rapidly in about five and a half hours.

As for run times, the duration is proportional to the logarithm of b, so an increase in b from 40K to 100K will produce a noticeable change, but not a huge change in run times. On my GTX 460 it would increase the time from 17 hours to 19 hours. At GeneferCUDA's maximum b of 695K the time would be close to 22.5 hours. (We'll stop before then because GenefX64's limit is 600K.)

I don't know where you are getting these numbers from, but my pair of non-overclocked GTX570's just did a four WU in just under 7.5 hours each. Maybe it's just your drivers or your not running at 100%.............

I tested them manually on my own GTX 570 ;)
You performed tests on numbers with b close to 20000. For those 7.5 to 8 hours is indeed what it should it take.

Edit And your card has been overclocked, whereas mine hasn't.

Your card is faster because it's overclocked. It probably came from the factory like that. Your GPU clock is 1690 MHZ. The stock clock speed is 1464 Mhz.

It sounds like folks are being able to run successfully with some pretty high overclocked cards (this is NOT what I'm recommending). Sounds like maybe the cooler/cold weather might be helping with the temps on the cards..

Anyway, good luck to all!

Rats rule and cows drool :)

There's still a VERY small number of the older, smaller, n=19 WUs still bouncing around.
EDIT: Down to 8.


As of 12/31 there's only 3 left.


As of 1/4 16:28 UTC (1:32 until the challenge) there are now only 2 remaining.

I'm adopting a more active and committed approach to cooling my main GPU. I'll overclock this 580 to 950MHz, and, having purchased 3,000 cans of compressed air, lay down on the floor and aim directly at the GPU fan. My girlfriend is helping me with switchovers (or "can replacement solutions", as we've come to call them), and is taking charge with a friend whilst I need to sleep. I say she's my girlfriend, I shouldn't call her that really, I'm only in it for the GFN challenge.

So Micheal, what do you suggest, that I should de-clock my stock cards, so that they run at the speed of reference cards(the majority of the cards out there). The pair I have come from Gigabyte and ARE hand picked parts that just happen to run at higher clock speeds and produce the same heat as reference cards. They also carry the same warranty as the reference cards, if they should happen to fry, running at 100%, they are covered. I send them back and Gigabyte sends me new ones. Just for safety, both my cards are water cooled, because when they weren't, they ran these same WU's at 80C to 85C. Oopps, the challenge is off and running.....got to go....happy crunching!!

So Micheal, what do you suggest...


My suggestion is always the same: When you're running GeneferCUDA, run at stock clock speeds.

That being said, if it's working for you and you're never seeing the "maxErr exceeded" error, then by all means run at any speed you want to. But if you get that error, the way to stop it from happening is to run at a lower clock speed and/or increase the cooling.

I'm sure it seems to me that EVERYONE who overclocks has errors, because not that many people come and say, "Help! Everything's working perfectly even though I'm overclocked!". Mostly, I only hear about the things that go wrong. :)

So I'm sure there's far more people who have success with overclocking than I'm aware of.

I'd say 75% of the conversations here on this topic go something like this:

Them: Help! I'm getting errors and I don't know why.

Me: You're getting the "maxErr" error, and your GPU is overclocked. Reduce the clock speed to the stock clock speeds and the problem should go away.

Them: My GPU isn't overclocked.

Me: (Looks at their GPU speed and the reference speed on Nvidia's website...) Yes, it is. You're running at XXXX MHz and stock speed is YYYY MHz. Your card probably came overclocked from the factory. It's still overclocked, however, and that's causing the problem. Try reducing the clock speed.

Them: (dubiously) Ok...

Them: (Sometimes) Thanks, that did it!


Whatever the problem in the hardware is, they're not testing for this when they bin the parts for the factory overclocked cards. Lots and lots of people have trouble running GeneferCUDA on factory overclocked cards at the speeds the GPU came at from the factory.

I've been unable to get any work for about an hr now for the contest. Running stictly on CPU.... got 8 cores available and only one is crunching an older GFN wu.... I'm wondering if because this work unit has been running for near 4 days now that it's holding up new work. I'd had to abort 100+hrs on a task just to get work for the contest...

Any ideas?

Message 61173 - Posted: 4 Jan 2013 | 19:05:01 UTC - in response to Message 61168.

I've been unable to get any work for about an hr now for the contest. Running stictly on CPU.... got 8 cores available and only one is crunching an older GFN wu.... I'm wondering if because this work unit has been running for near 4 days now that it's holding up new work. I'd had to abort 100+hrs on a task just to get work for the contest...

Any ideas?


First of all, jump over to the chat room (link is on the left, right below the link for these forums) so we can figure this out in real time.

While you're going over there, I'm going to think about this. :)

Of your 4 machines, only the Win 7 machine should be able to participate.

You need either a 64 bit system OR a DP capable Nvidia GPU.

Your two XP machines are running 32 bit versions and don't have a GPU, so they can't run either GeneferCUDA nor GenefX64.

Your vista machine has a GPU, but it's not DP capable and can't be used. So the Windows 7 machine is the only one that should be able to download any GFN work.

It *might* be possible to run 64 bit Linux in a VM on the other machines if they have a 64 bit CPU, even though they're running 32 bit versions of Windows. Whether you can do it depends on the features of your CPU and your technical ability.

Hello!
Sorry for my English.
May be I'll do only 1-2 tasks with my i3 in this Challenge, but nevertheless here is my question: why I can't to decrease use of CPU time? I mean, in preferences the CPU time is 80%, but task manager demonstrate that process (primegrid_genefer_2_3_0_0_ ...) takes 25% of i3 (one core).
I did abort some tasks, restarted BOINC, but that didn't help. What else can be done?

Yes, lying down here 24/7 until I fall asleep, but I've got plenty of coffee so I should last half the challenge before my helpers take over.

Instructions on the spray I've got say things must be off & cooled before use.


It says 50°C and to be honest, they're covering themselves, aren't they. My GPU temp is 63°C, so the heatsink will be very slightly cooler anyway. The spray is freezing cold upon impact at close range too, hence the frostbite to skin warning, so itll probably cancel that difference out. If it does all go up in flames then apparently the MSI Twin Frozr fans are unreliable, so hopefully they'll stop quite quickly and the burning PC will only destroy part of my home.

Edit: I'm joking about the whole thing, I didn't think people would take it seriously. Sorry to clog the thread. I am very much in on the challenge, though.

If you set cpu time to less than 100%, boinc uses 100% of one core, but suspends the task at short intevals. At 80%, it works 4 seconds and then stops 1 second and so on. After 5 minutes, cpu worked 4 and rested 1. However, for some reason, some versions of boinc are unable to suspend genefer cpu tasks. If you suspend it, the clock stops but it keeps crunching on the background. So to avoid use of 100% cpu just select use 25 or 50% of cores. Work will be spread among all cores and none will be working at 100%.

Sorry had to go to back to work after my lunch break to come home and start the contest.

Now though, I have work. Whatever it was worked itself out or someone adjusted the settings somewhere. Whatever it may be, I have work and am happily crunching.

PS. Got that new amd fx8350 cpu in under 10min.... will see how it crunches compared with the fx 8120. Should be a significant difference.

Now though, I have work. Whatever it was worked itself out or someone adjusted the settings somewhere. Whatever it may be, I have work and am happily crunching.


We didn't change anything on our end.

no idea then... came back from lunch 2hrs later and found wu's crunching for about an hr and a half. Started automatically. Still got that other wu going for 105+hrs now. Anxious to see what this cpu upgrade did... And man, I want some nvidia cards, or at least one card, in one of these older machines I got going around... would make all the diff in this contest. Last few contests I'm proud to say I've placed in at least the top 33 percentile with only the cpu or gpu for sieves. GPU in this contest will really be key. I bet I don't go about top 50 percentile in this with just 7 cores running... should have been a 30 day contest ;)

I have 2 computers which are showing outlandishly long run times of 8500 and 10200 hours.

I know those aren't terribly powerful systems, but are those numbers accurate? If so I can use them for other project where they could be more useful.

BOINC is ridiculously bad at predicting times, so no, they aren't realistic. Wait until a WU gets to something like 20%, then multiply the time elapsed by 5, ignoring what BOINC says will remain.

I'll look into it.

EDIT: It looks like the team score is correct. The individual scores are multiplied by 10. Should be easy to fix...

That's a 32 bit version of linux, correct? The CPU program is 64 bits and won't run on a 32 bit machine. If it's a 64 bit CPU, you could install a 64 bit linux distro and then you should be able to run GFN.

If you're running on a GPU you can use either 32 or 64 bit systems, but on the CPU it has to be 64 bit. (32 bit software exists but is too slow. If you want to crunch GFN on a 32 bit CPU you can do that on PRPNet.)

You are correct, the 2gb flash I used was for 32 bit. I got to hunt for the 64 bit. My mistake. I pulled these systems from the attic and have not booted them for a year.

Some statistics at the 24 hour and a surprise (for me). It looks like my old gtx280 will complete a task at the 32 hour mark. gtx570 and 460 are completing at 8.8h. and 17h respectively.
Since the gtx280 has about the same flops and memory as the 460 I assume the difference is its 1.3 capability compared to the 2.1.

cpu's percent complete (average all cores)
Q6700 %9.1 done
Q9550 %6 done
Opteron290 %5.3 done.

I would be interested in any values for i7 core %done

Thanks!

i5-2500k @stock ~20% on the 24 hour mark (40k tasks).

I imagine that we will see a great jump on tasks done by Tuesday and Wednesday, when the cpus start to return their wu's.

If you have never run GeneferCUDA before, please read these tips. GeneferCUDA stresses a GPU more than any other program I've seen and is incredibly intolerant of overclocking.


In my opinion, GFN is a regular crunching stress for GPUs. Almost every BOINC GPU app that can load GPUs at 99% gives almost the same GPU stress.
GFN on GTX470 - 76'C
DiRT on the same GTX470 - 79-80'C
GFN on GTX560Ti - 63'C
DiRT on the same GTX560Ti - 66'C
Room temperature is the same in all cases.

What is a source of information about problems with overclocked GPUs @GFN app?
Is it a single story or numerous reports?
I totally disagree with the statement like that.

If you were a regular reader of these forums you would have your answer to your 2 questions.
There are pages of work unit from hundreds of users with failed work units.

That pretty much covers it, other than the fact that the problem can be resolved by increasing cooling. That points to a hardware problem, although the exact nature of the problem is, unfortunately, unknown.

The numbers we're crunching are of the form B^N+1. For all the work in this challenge, N is 1048576 and B increases with each work unit. B values are always even and we started at B=6 back at the beginning of November. At the start of the challenge, B had increased to about 40K (40 thousand), and during the first day of the challenge B had increased to about 60K. We have work loaded up to 125K. That should be plenty of the entire challenge, but we can load more if needed.

I totally disagree with the statement like that.

ThrasherX-17, the reason lies in the nature of Genefer algorythm, how it uses GPU. In contrast to, for example, PPS Sieve, where GPU loading level is the same high - 99%, Genefer uses GPU Memory Controller very intensive.
Previously many-many folks have got failed Wus after validation.
The temperature is a big factor, but not the main.
Many people have had to downclock GPU Memory Clock and maybe GPU Core Clock to stock clock or even lower to achieve WU validation.
So I expect very hot endgame of the challenge when it turns out that the former leaders go down after validation... Don't mind you, but all who on the contrary overclocked their GPUs.

If you were a regular reader of these forums you would have your answer to your 2 questions.
There are pages of work unit from hundreds of users with failed work units.
The posted warning is a just one. I'm sure Mike will chime in with more detail.

Last year we've run the GFN challenge. I remember those very hot summer days. I kept all of my GPUs at the highly OC level. The GPU temps were insane. I could finish the challenge with almost all WUs validated. I was surprised and thought that all warnings were because of the GFN newness.
A lot of time has passed but we all still see the same warnings.
I wouldn't start this dialogues but some of my team members have read the official thread and started to downclock their GPUs.
Also I'm very sad about the fact that this discussion is too late and I feel myself guilty because I haven't seen that warnings before the start of the challenge. Probably it's better to stay with the tested settings during the event.

Happy challenge everyone!

I wish that were true! It wasn't just a general warning, unfortunately. We had -- and still have -- many many people who have problems with overclocking.

The nature of online forums is that we hear about many of the failures, but few of the successes. It certainly seems to us that a vast majority of people who overclock their GPUs have problems with it. I'm sure that impression is distorted somewhat since people who don't have a problem with it don't have a need to come here and post about it.

I'm glad you are able to run at high clock rates. Many others aren't, and I wouldn't mind knowing why. There's been some speculation lately by myself and others that the size or quality of the power supply may play a role. That's certainly possible, but I have insufficient information either way to know for sure. Certainly, having a power supply that's too small or the quality is poor absolutely will cause you problems with a GPU, but I don't know if that's the cause here.


I wouldn't start this dialogues but some of my team members have read the official thread and started to downclock their GPUs.
Also I'm very sad about the fact that this discussion is too late and I feel myself guilty because I haven't seen that warnings before the start of the challenge. Probably it's better to stay with the tested settings during the event.

I can only make recommendations, of course. People can choose to run their hardware at any speed they want. But it would be negligent of me not to warn people. I'm sure that everyone would rather get 10% or 20% less credit than 100% less credit. If you know that your machines can run Genefer at a certain clock rate without error, then by all means do so. Most people aren't going to listen to warnings anyway if they think their hardware can handle it. If they're right, great! If not, at least they know where to look to correct it.

Michael, I've never criticized any recommendations from PG moderators since my very first challenge in 2010. And I used to respect all the positive and negative experience in PG crunching.
It's good to see how much you care but sometimes recommendations are very radical (in my opinion of course).

I have 4 types of NV cards running the GFN challenge (GTX470, GTX460, GTX560Ti, GTX570).
All of their cores are overclocked +120-200MHz.
My PSUs are not great. CoolerMaster 850W/FSP Epsilon 800W/Antec 550W.
Also I have 1 problematic GTX470 that sometimes gives errors in almost all BOINC GPU applications (PG, DiRT, Einstein etc) no matter with or without overclocking.
The other GPUs are feeling fine with GFN and PPS Sieve WUs.

I can't say the same thing about CPU overclocking.
Some CPUs are giving errors but I checked them and figured out that those CPUs are giving errors even at default frequencies.

Anyway I will be more confident when all the WUs will be validated. Time will tell.

Message 61298 - Posted: 6 Jan 2013 | 15:55:18 UTC

Well...just to ad my 2 cents to the overclocking discussion for GFN...

I run several different machines with different success with overclocking on GFN for various GPUs. For example, I have a dual GTX 460 (the 768mb variety) system running very highly overclocked GPUs (factory overclocked ASUS TOP models that I have pushed even further...to a 1734 shader clock!). This machine has successfully completed and validated GFN262144, GFN524288, the current challenge work, and GFN world record work without any problems (I have a wildly overclocked GTS 450 ASUS TOP model with the same results). Note, however, that I have not increased the memory clock over the factory OC. Also, I have swapped numerous power supplies in and out of this dedicated crunching system as other machines have had need for the PS I was using here, and these have ranged from a nice corsair model to an emergency install of a very cheap 400 watt PS while I waited on an RMA for a better one to be returned from the manufacturer.

On the other hand, my wife's machine had a factory OC'ed GTX 550 Ti that would successfully complete GFN262144 units without problem, but would not do even a single GFN524288 unit without error. I dropped only the memory clock down to 1700 (below even the stock GTX 550 Ti), and now this card has successfully completed GFN524288 work as well as work in the current challenge.

I also have access to two laptops with Fermi cards (a GT 525M and a GT 540M). The GT 525M card works just fine, albeit quite slowly, on the GFN262144 and GFN524288 work (I am not running it on anything longer). The GT 540M (which is essentially an overclocked version of the 525M that NVidia markets under a different name) will not even complete the GFN262144 work without erroring out.

So what have I learned about GFN work and overclocking (and yes, much of this is repeat from what Mike has posted already):

1. Heat is a killer. It over stresses the system overall and the GPU in particular. What temperature hits the problem point, however, varies greatly with GPU model (e.g., different for a GTX 560Ti vs. a GTX570) and within GPU model (e.g., different for a GTX 460 ASUS TOP model vs. a basic EVGA non-overclocked GTX 460). You have to experiment to find the sweet spot for each card.

2. Always adjust the memory clock first in the face of errors on GFN. It is quite common to be able to run overclocked core/shaders while needing to run stock clocked or underclocked memory. This is just the unique nature of the GFN work and how intensively it uses the GPU memory and memory controller. **note this is always the case on the GTX 550Ti due to the unusual memory configuration placed on it by NVidia (and perhaps a handful of other cards)**.

3. As the GFN N goes up (e.g., 262144, 524288, etc.), you may need to adjust the "sweet spot" for each card. This is especially true for the memory clock, but may also affect the core and shader clocks. Cards that ran the GFN524288 work without issue may begin to encounter problems as we move up to the challenge work or on the world record work.

4. Pay close attention to the driver you are using. The problems with the 295 and 296 drivers from NVidia are well known, so I won't repeat them here. Other drivers (even those not yet written and released) may cause further problems. If you are changing drivers, you need to pay very close attention to your GPU crunchers to make sure that no new problems arise...if they do, just switch back to the old driver and wait for the next release (which will often, though not always, fix the issue).

Bottom line...if you are GFN crunching, and especially if you are doing so with some overclocks, you need to be more of an active cruncher rather than a passive (i.e., set it and forget it) cruncher.

There's still a VERY small number of the older, smaller, n=19 WUs still bouncing around.
EDIT: Down to 8.


As of 12/31 there's only 3 left.


As of 1/4 16:28 UTC (1:32 until the challenge) there are now only 2 remaining.


As of 1/6 10:17 there's only 1 remaining.

UPDATE

About 51 hours into the challenge:

17,937 tasks have been sent out.

Of those tasks that have been sent out:

8,504 came back with some kind of an error.
1,983 have returned a successful result.
7,456 are still in progress. (It's too soon for any CPU task to have come back yet.)

Of the tasks that have been returned successfully:

1,462 are pending validation.
505 have been successfully validated.
18 are inconclusive.

Of the errors:

8487 had some sort of client or computation error.
26 had no reply. (i.e., the host erroneously determined before starting the task that it had already missed its deadline due to the host's clock being set more than 19 days into the future.)
16 failed because the client detached.

Of the client errors:

1,333 had an error downloading from the PrimeGrid server.
6,178 had a computation error of some sort.
983 were aborted by the user.


The current leading edge (i.e., latest work unit for which work has actually been sent out to a host) is b=64392. The leading edge was at b=41616 at the beginning of the challenge. In two days, the leading edge has advanced more than half as much as it had in the first two months!

(If that seems like a lot of errors, it is! But it doesn't mean that lots of computers are having difficulties. It takes only a few seconds usually for an error to occur, so a single badly configured host can generate hundreds of errors very quickly. By contrast, a successful task takes anywhere from several hours to several weeks to complete. So with projects with long tasks, like GFN, it's typical to see a relatively high number of errors even though the percentage of hosts returning errors might be similar to shorter projects.)

As Scott brown says above the error problems are very variable, the same card type can show different symptoms on different machines, with different PSU or temperature etc.

I have found the same applies to the driver. For 4 months I ran 296 on a 680M without problems (it came with the new laptop). Then Microsoft offered an update I accepted and, to use the local term, it was buggered. I got the new 310 driver from NVidia and all is well again.

Many others have found the 29x series of drivers to be a disaster.

As others have said, if it works for you then fine, but if you follow the advice then you can be fairly sure of no problems at a slight cost of maybe a little longer per job.

At least most of the errors from this problem happen fairly fast (or mine did) so there is about the same impact as aborting a job which is not too bad for PG provided you check your own error rate and stop work to solve any problems before you error a couple of thousand WU.

UPDATE

About 74 hours into the challenge:

21,472 tasks have been sent out.

Of those tasks that have been sent out:

10,221 came back with some kind of an error.
3,197 have returned a successful result.
8,060 are still in progress. (It's probably still too soon for any CPU tasks to have come back yet.)

Of the tasks that have been returned successfully:

2,086 are pending validation.
1086 have been successfully validated.
4 were invalid.
23 are inconclusive.


The current leading edge (i.e., latest work unit for which work has actually been sent out to a host) is b=68836. The leading edge was at b=41616 at the beginning of the challenge. In three days, the leading edge has advanced 75% as much as it had in the first two months!

Question, you listed 24k sent out and 11.8 k returned with error so how much of the 24k is repeat or are you counting the 24k as all new work and thus figured the leading edge on that?

Just curious. Rick

Generally speaking, every error needs to be sent out again. Ignoring the errors, 4400 tasks have been returned successfully, and 8600 tasks were sent out and are still in progress. Perhaps that's a better way of looking at the data.

Another useful way of looking at the data is available to everyone: The number of GFN tasks shown on the front page started at 25000 at the beginning of the challenge. You can watch it drop day by day, and that will give you a very good idea of progress. Since errors go back into that queue, errors don't cause the number to go down. It only goes down when a computer grabs a task to do. If it errors, the number goes back up as a replacement task is created.

The leading edge is really simple: it's the highest numbered workunit for which a task has been sent out. Chances are it hasn't been returned yet, so it's "in progress" and neither an error nor a success.

My AMD FX 8350 tasks are about 42-43% done, but dats all I got. I hope they come through without error.

I think that error rate on cpu is much lower than on gpu. In a day or 2 there should be a significant number of cpu tasks being returned successfully.

My AMD FX 8350 tasks are about 42-43% done, but dats all I got. I hope they come through without error.


Barring something like a computer crash, which sometimes kills BOINC jobs, there's no reason to think they won't succeed. The CPU version of Genefer isn't more prone to errors than any other program.

As I said a few updates back, it takes about 5 seconds to do an error and anywhere from about 10 to a few hundred hours to do a successful computation. A computer that's misconfigured is going to spit out hundreds and hundreds of errors in a short period of time. Most of the errors are from the GPU tasks as there's a lot of things which all have to work right for the GPU to work properly. If any of them are wrong, you get errors -- usually a lot of errors.

The number of computers producing errors is much lower than 50%.

A 50% error rate for tasks like this, taking into account the length of the tasks and that many of them are on a GPU, is actually very good. To be sure GeneferCUDA in particular has its own idiosyncracies that make it somewhat more error prone than other programs, but that's primarily a problem on the longer World Record tasks than on the short tasks we're using for the challenge.

UPDATE

About 5 days into the challenge:

30093 tasks have been sent out.

Of those tasks that have been sent out:

15123 came back with some kind of an error. (2713 CPU / 12386 GPU)
5796 have returned a successful result. (76 CPU / 5689 GPU)
9174 are still in progress. (4687 CPU / 4462 GPU)

Of the tasks that have been returned successfully:

3103 are pending validation. (34 CPU / 3048 GPU)
2639 have been successfully validated. (42 CPU / 2588 GPU)
11 were invalid. (0 CPU / 10 GPU)
43 are inconclusive. (0 CPU / 43 GPU)

The current leading edge (i.e., latest work unit for which work has actually been sent out to a host) is b=77838. The leading edge was at b=41616 at the beginning of the challenge. Since the challenge started, the leading edge has advanced 87% as much as it had in the previous two months!

11 were invalid. (0 CPU / 10 GPU)


Scott pointed out this seeming inconsistency. The extra 11th task here is an anonymous platform/app_info.xml task and doesn't count as either CPU or GPU.

Device 1 tasks fails only. Lower GPU/memory clock (from 767MHz) - I had to set 700/1800 Mhz on my GTX460 (from 800/2000)

About 6 days into the challenge:

33659 tasks have been sent out.

Of those tasks that have been sent out:

16547 came back with some kind of an error. (2830 CPU / 13693 GPU)
7477 have returned a successful result. (219 CPU / 7220 GPU)
9635 are still in progress. (5070 CPU / 4540 GPU)

Of the tasks that have been returned successfully:

3582 are pending validation. (100 CPU / 3457 GPU)
3824 have been successfully validated. (119 CPU / 3693 GPU)
17 were invalid. (0 CPU / 16 GPU)
54 are inconclusive. (0 CPU / 54 GPU)

The current leading edge (i.e., latest work unit for which work has actually been sent out to a host) is b=83568. The leading edge was at b=41616 at the beginning of the challenge. Since the challenge started, the leading edge has doubled!!! Well done everyone! Can we triple it by the end of the challenge?

If by that you mean you aborted them, that's fine.

If you meant they're showing up as 'abandoned' and you don't know why and you think it may be some sort of error, THAT is something I'm concerned about. If that's the case, more details would help.

The most likely cause of this is your computer disconnecting from PrimeGrid (and then reconnecting.) If you use an account manager such as BOINCStats BAM! putting the wrong setting into BAM! could cause this.

Googling the problem, I found that this has happened sometimes following a crash of the client computer, although I've never seen that myself.

Aside from that, I don't know what to tell you. That flag says that the tasks were cancelled because the client computer disconnected from the project, so that's what the server thinks happened. What does your boinc client log show happened at that time? (CTRL-SHFT-E to see the log since the last BOINC restart, or look at c:/ProgramData/BOINC/stdoutdae.txt to see the log prior to the last restart.)

Here's an extra special bonus update at the 50% mark:

34733 tasks have been sent out.

Of those tasks that have been sent out:

17053 came back with some kind of an error. (2859 CPU / 14170 GPU)
7986 have returned a successful result. (274 CPU / 7671 GPU)
9694 are still in progress. (5191 CPU / 4478 GPU)

Of the tasks that have been returned successfully:

3741 are pending validation. (127 CPU / 3592 GPU)
4161 have been successfully validated. (146 CPU / 3998 GPU)
17 were invalid. (0 CPU / 16 GPU)
67 are inconclusive. (1 CPU / 65 GPU)

The current leading edge (i.e., latest work unit for which work has actually been sent out to a host) is b=85096. The leading edge was at b=41616 at the beginning of the challenge. Since the challenge started, the leading edge has advanced 104% as much as it had in the previous two months!

I think it is safe to say with our progress that we will easily cross b=100 000 by the end of the challenge. Is this n going to end at 700 as well? Because if so then that puts us at 1/7 of the way done with the value of n, granted it will take at least a year or two to finish it off...

With the current version of GenefX64 it will be 600, probably. Maybe a little before that. But I expect we'll be using a different version of Genefer long before we get close to that. I can't predict whether the new version will have similar limits or not.

Most likely a couple of months, certainly till it's on BOINC. Testing on PRPNet might be a lot sooner.

With the current version of GenefX64 it will be 600, probably. Maybe a little before that. But I expect we'll be using a different version of Genefer long before we get close to that. I can't predict whether the new version will have similar limits or not.

If the new version has better (higher) limits, will we go back and resume some lower n's?

No thought has been given to that, in part because there's so many unknowns right now that it's pointless to speculate on that. Can we add new app versions? (Probably soon.) Can we add more projects? (Unknown.) Can we find a way to add a lot more projects (also unknown.) When will the new apps be ready? (Hopefully in no more than a few months, but also unknown). Will the new apps solve some of the problems we're having with GFN? (Unknown.) What will the limits be (Unknown.) Will we open up GFN-WR to CPUs? (Unknown.) Will we open up n=21 simultaneously? (unknown.)

My guess would probably be no, because I don't expect a big change in the limits because the same size registers are being used. But it's too soon to even think about that.

UPDATE

About 7 days into the challenge:
36653 tasks have been sent out.

Of those tasks that have been sent out:

17891 came back with some kind of an error. (2936 CPU / 14931 GPU)
8959 have returned a successful result. (478 CPU / 8439 GPU)
9803 are still in progress. (5324 CPU / 4440 GPU)

Of the tasks that have been returned successfully:

3993 are pending validation. (206 CPU / 3766 GPU)
4862 have been successfully validated. (267 CPU / 4577 GPU)
19 were invalid. (0 CPU / 18 GPU)
84 are inconclusive. (5 CPU / 77 GPU)

The current leading edge (i.e., latest work unit for which work has actually been sent out to a host) is b=87862. The leading edge was at b=41616 at the beginning of the challenge. Since the challenge started, the leading edge has advanced 111% as much as it had in the previous two months!

Was just wondering what the average number of successful units returned by day was before the challenge just to see how much of a bump in activity there has been due to the challenge.

Also, isn't the leading edge somewhat misleading in that after the challenge there will be alot of work done to "fill" in the gap or will you just continue to issue new work from the leading edge? Sorry, I know this isn't all that important just being curious.

During the First 3 days of Janurary, on average 430 successful results were returned each day. In the first 7 days of the challenge, an average of 1314 successful results have been returned.

If you look at tasks sent out, the average is 1765 tasks per day during the first 3 days of January and 3555 per day during the 7 days of the challenge.

As for the second question, I'm not sure what you mean by "fill in the gap", but there's many methods of gathering statistics. The one I like best is "Number of primes found." :)

I think he means the gap between the leading edge and the trailing edge, the smallest b whose primality status has yet to be decided. In other words, won't the leading edge grow more slowly after the challenge while we do clean-up work?

If that's so, I don't think the gap is in any way meaningful because the trailing edge is usually defined the most unlucky WU. That would be the poor number that had the misfortune to be sent to multiple hosts that subsequently vanish, with each one chewing up 19 days. That isn't really meaningful in the context of trying to gauge how much work was done.

After the challenge, the leading edge will grow more slowly because there's fewer computers working on GFN. Both clean up work and new work occur both during and after the challenge. The only difference is that (I think) we lower the buffer size after the challenge so that there's less new work. The goal is to skew the available hosts towards task resends instead of new work units. But both occur at all times.

Well, I've been running this on my laptop because it is all I got. And it is killing me with crazy completion times. ;) I know from previous WU's that it will eventually correct it's self. But, kinda crazy to get one and see a completion time of over 6k hours!!! My first one started with about 6,450 hours and so far has taken 122 hours with now only 277 hours to go! Will be interesting to see how long it actually takes. I was able to pull down two more WU's and they also started with over 6k hours. Probably only going to take about 140 hours.

I guess I'm just doing it so that I know I did participate in the challenge. Would be crazy if I did actually find something while doing it. Talk about bragging rights!

Remember to always crunch safely, and responsibly. Other wise you just become a Crunch Monkey!!!

I guess I'm just doing it so that I know I did participate in the challenge. Would be crazy if I did actually find something while doing it. Talk about bragging rights!



Sooner or later, hopefully someone will find a prime at N=1048576, and when that happens it will be a pretty big event (and a VERY big number!) We're already beyond the point where the first prime was found at N=524288, and we've been working on this for only two and a half months. That's pretty amazing considering it took about 10 months to get to this point with N=524288, and those tasks were almost four times shorter.

Fortunately it won't take as long as it would have taken a year ago.

Running LLR on a that number on my C2Q would take about 18 days -- but there's faster CPUs and an AVX version of LLR, so I would guess 3 to 5 days on the fastest CPUs.

Thats what it takes to run genefer64. I thought llr was a much slower test. Good to know I was wrong.

That's my estimate for LLR. GenefX64 is, of course, faster (roughly 8 days on my machine running on one core. With all 4 cores going, it's running a lot slower, around 12-13 days. Either my estimates are off or the larger numbers are causing significant cache miss problems on this CPU.)

UPDATE

About 8 days into the challenge with 5 days remaining:

39498 tasks have been sent out.

Of those tasks that have been sent out:

19152 came back with some kind of an error. (3068 CPU / 16059 GPU)
10600 have returned a successful result. (833 CPU / 9706 GPU)
9746 are still in progress. (5421 CPU / 4301 GPU)

Of the tasks that have been returned successfully:

4340 are pending validation. (332 CPU / 3982 GPU)
6132 have been successfully validated. (494 CPU / 5606 GPU)
24 were invalid. (0 CPU / 23 GPU)
103 are inconclusive. (7 CPU / 94 GPU)

The current leading edge (i.e., latest work unit for which work has actually been sent out to a host) is b=92004. The leading edge was at b=41616 at the beginning of the challenge. Since the challenge started, the leading edge has advanced 121% as much as it had in the previous two months!

Has anyone else noticed that the scoring is a little unfair for similar speed machines?

Consider machine A can do 5.9 jobs in the challenge, machine B does 5.1. Both get credited with the points for 5 jobs but because machine B is a little slower it gets work a little later and hence with a higher b value and more points.

The faster machine is penalised.

It is difficult to see how this can be resolved, and I admit the resends will help to even things out a bit but watching the scores change I see it actually happening. I go to 3 jobs, say 17000 points and most of those who go to 3 jobs after me get a slightly higher score and go in the table above me.

This is just an interesting observation, not a major complaint.

The differences in points between tasks that close won't be very significant, but could, as you say, result in the slower computer ending the challenge ahead of the faster computer.

However, if the faster computer was just a tiny bit faster, and completed 6.000000 tasks, it would be way ahead. Also, the time when the first WU was downloaded would also play a role in making small changes to the points served, for the same reason.

In practice, however, as you say, there ARE resends. Lots of them. It's unlikely that a computer with a GPU (and thus running multiple tasks) would go a whole challenge without doing any resends. My computer has done a few already, I think.

EDIT: I just checked. My computer has received 7 resends and 8 initial tasks. However, 5 of those 8 were downloaded in the first few seconds of the challenge when almost all tasks were new. Excluding the start, it's 7 resends and 3 new tasks. Having the resends in there pretty much obliterates the tiny differences in credit scores based on sequential timing of the task requests. I don't think you have to worry about slower computers having an unfair advantage. :)

If a PRP is found around 100k range, how long would it take to check primality?


Fortunately it won't take as long as it would have taken a year ago.

Running LLR on a that number on my C2Q would take about 18 days -- but there's faster CPUs and an AVX version of LLR, so I would guess 3 to 5 days on the fastest CPUs.

Thats what it takes to run genefer64. I thought llr was a much slower test. Good to know I was wrong.


That's my estimate for LLR. GenefX64 is, of course, faster (roughly 8 days on my machine running on one core. With all 4 cores going, it's running a lot slower, around 12-13 days. Either my estimates are off or the larger numbers are causing significant cache miss problems on this CPU.)


My momma always told me to do my homework --- The only reason I passed school is I excelled on exams... If I read this PRIOR to starting this challenge...

My 2 machines are normally very good performers on cpu wu's, so I committed one of my own sins and ASSumed they would be on task to handle these babies....

So after the challenge started and I got all my cpu queues cleared I loaded all 8 threads on both machines with Genefx64 wu, and knowing the challenge was still a week and a half to go, I just let BOINC run...

Then last night with 3 nights to go I was curious as to what the progress was, and to my chagrin, nothing above 52%; I crunched the #'s and nothing was going to complete in time!!! My rough calculation said that maybe 2 units MIGHT make it if I set to one core each machine... but even then, not likely... So, adios to (cpu) Genefer [I'll finish my gpu tasks]... I'll know better next time.

The lesson here, boys and girls - do your homework, check the forums and read the readme's!

Whether to Continue Late Running Tasks

This is a question that's been asked of me privately, as well as on the forums more than once.

This is a decision for each individual to make, but you should have all available information when making this decision.

A few things to consider, depending on what your priorities are:


  • Each task is worth about 27000 credits. You won't get any challenge points if the task is returned after the challenge ends, but you still get BOINC credit.

  • Although the challenge runs for 13 days, the deadline on the tasks is longer: 19 days for most WUs. You have more time to complete the tasks even if they won't finish in time for the challenge.

  • For those of you not very familiar with Generalized Fermat Numbers, this search is what I consider a "target rich environment" as far as searching for HUGE prime numbers is concerned. If you look at the mega-primes found by primegrid over the last year, half of them have been GFNs, and the four largest primes ever found here are GFNs. Your future wingman will thank you if the task you kill turns out to be his discovery of the largest prime number ever found at PrimeGrid. :)

  • If you decide not to continue running tasks already in progress, please abort them. Aborted tasks can be immediately resent by the server to other computers.



REMINDER: Make sure your computer returns all completed tasks BEFORE the challenge ends! Tasks returned after 17-January 18:00 UTC WILL NOT BE COUNTED FOR THE CHALLENGE. The deadline for these tasks is longer than the challenge itself, so you can't rely on BOINC automatically returning the tasks before the challenge ends.
