Welcome to the World Expo Challenge

An 8 day Challenge celebrating the start of the start of the World Expo in Milan is being offered on PrimeGrid's Generalized Fermat Number (GFN) application. Both long and short tasks are part of this challenge. To participate in the Challenge, please select either of the Generalized Fermat Prime Search project in your PrimeGrid preferences section.

The challenge will start on 23 April 2015 18:00 UTC and end 8 days later on 1 May 2015 18:00 UTC.

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


Application Builds


    Application builds are ONLY available for double precision Nvidia AND AMD GPUs. For NVidia GPU's there are two versions CUDA and OpenCL. Please read the next post for more information on it. 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 any GPU that lacks double precision hardware can't be used. Please see the list of Compatible GPUs for NVidia and for AMD/ATi more details.


A Cautionary Reminder


    ATTENTION: The primality programs GeneferCUDA and GeneferOCL (GPU) are computationally intensive; so, it is vital to have a stable system with good cooling. It does 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're using an Nvidia GPU and 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.

    WR WU's will take about 5 days on a GTX 580 GPU. 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 12 days on the GPU. For a general idea of how your GPU stacks up, you can have a look at the fastest gpu list

    If your CPU is highly overclocked, please consider "stress testing" it. Overclocking your GPU is 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 23 April 2015 18:00 UTC and received BEFORE 1 May 2015 18:00 UTC will be considered for credit.

    In this challenge we will be using the same scoring algorithm as we use to determine BOINC credits, including bonuses!. Because the score bonuses are included in the challenge score, it is advantageous to run the longer tasks if you can manage to finish them within the 8 day challenge window. This will land you a higher position in the leaderboard and therefor a higher score on the overal leaderboard.

[u]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 "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 PPSE (LLR)
    -At Challenge start, update PrimeGrid preferences and only select the GFN World Record project
    -At worse, you'll only be 1 PPSE (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 (World Record) project
  • a few computers, user can be present at start
    -Change PrimeGrid preferences and only select the GFN (World record) 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 alows them to be recycled immediately; thus a much faster "clean up" to the end of a 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.

The end is near!

Literally.

As luck would have it, we're close to running out of n=20 (GFN-Short) candidates. As you know, with the Genefer program we can only search a limited range of 'b' values before the accumulated rounding errors start impacting the calculations.

Our best guess is that we probably will NOT run out of tasks during the challenge -- if you're looking at the tasks that get completed. However, many tasks will be downloaded but not completed, or will generate errors (especially GPU tasks), and it IS likely that the number of tasks that get sent out WILL exhaust our supply of n=20 tasks.

So we're doing things a bit differently during the challenge.

First of all, the 'b' limit on the GeneferCUDA program is LOWER than the 'b' limit on GeneferOCL, so I STRONGLY RECOMMEND that everyone who is still using GeneferCUDA switch over to using GeneferOCL. When we start sending out tasks close to the GeneferCUDA 'b' limit I will be disabling the GeneferCUDA apps, and if you have only GeneferCUDA selected you will no longer get GFN-Short tasks. Even if you're running with app_info you should switch because the GeneferCUDA app will start failing with "computation errors" due to the 'b' limit.

The CPU version of Genefer, as well as the OCL version have a bit more leeway, but when you include all the tasks that will error out or be abandoned, we're still may run out. There's several steps we're taking to insure that we'll have enough tasks for the challenge.

1) Instead of sending out 2 tasks per workunit, the server is now sending out three tasks per workunit. This change only affects GFN-Short tasks and has the side benefit of faster validation. Sending out three tasks will increase the available tasks by about 50%. We may, if needed, increase this to 4 tasks per workunit to gain additonal leeway. Please note that, on average, a GFN-Short workunit needs 4.2 tasks before getting two successful tasks that match.

2) To prevent hoarding, the server will only send out 2 tasks per CPU core or per GPU. This will remain in effect until the end of the challenge. Tasks downloaded before the challenge starts wouldn't count for the challenge anyway. This affects ALL subprojects. We apologize for any inconvenience this may cause.

3) We consider it unlikely, but in the event that we do actually run out of GFN-Short tasks during the challenge, the remainder of the challenge will run with only GFN-WR tasks plus whatever Short tasks trickle back into the system. We may consider sending out 5 tasks per workunit, but we'll make that decision later on if needed. We don't expect to use that many tasks.

In case you're wondering about switching GFN-Short to n=21, that will NOT happen during the challenge. Those tasks are a lot larger than the current n=20 tasks, and would certainly cause lots of confusion during the challenge.

No decisions about n=21 will be made until after the challenge ends.

Oops. Messed up the time conversion, and what, uh, day it was. I now have three WUs that are scheduled to finish in ~150 hours, which means that when the second lot are crunched, the challenge is over.

Brilliant :P

If you're only a few percent through and you're serious about the challenge you can always just abort the tasks you've grabbed and wait until the challenge starts to get new ones. If you'd rather not discard your computing time just because of an abstract challenge, then you've made the decision already. You'll still end up helping with cleanup.

A few questions from a total newbie and especially with no processing experience (yet) with GFN-Short:

(1) the preference page suggests a CPU runtime of 120 hrs and this is something I can live with since the runtime estimates for two other subprojects were quite good (I am using a duo core laptop with 2.67 GHz P9600 CPU). This translates to five days' of processing and which easily falls into the eight-day window of the challenge while also allowing for a generous "buffer" in the event my laptops require slightly more than the suggested 120 hrs. Are the specs for my CPU something to worry about or should I be fine?

(2) there is no sense in my downloading the temporary maximum of two WU's per CPU core since I will like to see how the first unit goes with respect to the 120-hr estimate. Is there a way for me to request only one WU and then for me to download a second WU if the first seems to be processing okay? All of this given the possible concern of running out of tasks for GFN-Short and where I would potentially be depriving someone else a valuable WU?

(3) I read somewhere in passing that units completing after the deadline will receive standard BOINC credit which suggests the credit will be different if it is completed during the challenge. If this is indeed the case, what kind of premium is there for timely completion within the challenge period?

(4) is it possible for me to specify greater priority for the GFN-Short units against the TRP Sieve units which will be in my queue over the next 24 hrs? I would prefer to get going with the initial GFN-Short WU once the window opens rather than wait 24 hrs for the TRP Sieve queue to clear so as to ensure the unit(s) completes on time.

Thanks.

Message 85087 - Posted: 23 Apr 2015 | 17:14:53 UTC - in response to Message 85086.

A few questions from a total newbie and especially with no processing experience (yet) with GFN-Short:

(1) the preference page suggests a CPU runtime of 120 hrs and this is something I can live with since the runtime estimates for two other subprojects were quite good (I am using a duo core laptop with 2.67 GHz P9600 CPU). This translates to five days' of processing and which easily falls into the eight-day window of the challenge while also allowing for a generous "buffer" in the event my laptops require slightly more than the suggested 120 hrs. Are the specs for my CPU something to worry about or should I be fine?


Your CPU is rather old. Not having AVX, it's going to definitely be slower than the average CPU time. Most Intel CPUs in use here have AVX, which significantly improves performance on these tasks.

Once the tasks start running, you can look in the stderr.txt file in each BOINC slot directory to see a fairly accurate time esitimate.

(2) there is no sense in my downloading the temporary maximum of two WU's per CPU core since I will like to see how the first unit goes with respect to the 120-hr estimate. Is there a way for me to request only one WU and then for me to download a second WU if the first seems to be processing okay? All of this given the possible concern of running out of tasks for GFN-Short and where I would potentially be depriving someone else a valuable WU?


Change you BOINC cache settings to 0 and 0. That will cause BOINC to not download any tasks until it's ready to run them.

That, by the way, is how I have my computers set up all the time. It makes it more likely that I'll be the person who gets credit for discovering a prime number rather than my wingmen.

(3) I read somewhere in passing that units completing after the deadline will receive standard BOINC credit which suggests the credit will be different if it is completed during the challenge. If this is indeed the case, what kind of premium is there for timely completion within the challenge period?


It's true that we give credit for late tasks, provided the workunit hasn't been purged from the database. Your assumption about different credit levels in incorrect, however. You get the same credit no matter when you return the task.

(4) is it possible for me to specify greater priority for the GFN-Short units against the TRP Sieve units which will be in my queue over the next 24 hrs? I would prefer to get going with the initial GFN-Short WU once the window opens rather than wait 24 hrs for the TRP Sieve queue to clear so as to ensure the unit(s) completes on time.


Just abort the TRP-Sieve tasks. We won't mind. :)

Thanks.

Are the specs for my CPU something to worry about or should I be fine?


Your laptop seems to be pretty close to one of my computers, so I will tell you what I know about the estimates. Most of them happen to be in the same range as your laptop (so your laptop is approximately an "average" computer, out of all computers on PrimeGrid). I would give a little overhead, say 135 hours for a GFN-short CPU for the first time. I haven't done any myself, though like you I plan to do one or two during the challenge once one of my SoB's finishes. Some of the estimates (such as SGS and PPSE) are a little on the short side since so many fast crunchers are doing those sub-projects, while the two CPU sieve estimates are a little longer because they are the shortest computations, so many people with slower computers run them.

(2) there is no sense in my downloading the temporary maximum of two WU's per CPU core since I will like to see how the first unit goes with respect to the 120-hr estimate. Is there a way for me to request only one WU and then for me to download a second WU if the first seems to be processing okay? All of this given the possible concern of running out of tasks for GFN-Short and where I would potentially be depriving someone else a valuable WU?


Just set your queue to 0 (those are your "Computer is connected to the internet every: _ days" and "Maintain enough work for an additional _ days" settings in Computing preferences). That way your machine will only request new work when one of your cores has finished a task, and there aren't any "Waiting to start." It only downloads new tasks when it actually needs a new task.

(3) I read somewhere in passing that units completing after the deadline will receive standard BOINC credit which suggests the credit will be different if it is completed during the challenge. If this is indeed the case, what kind of premium is there for timely completion within the challenge period?


There is no credit premium as such during a challenge. However, tasks started and returned during the challenge will count towards the challenge credit. The challenge is really just leaderboard for who gets the most credits in a certain subproject (or subprojects) during an 8-day period. Note that as long as you recieved and returned the task during the challenge, it counts, even if the WU wasn't validated during the challenge. This "challenge cleanup" you may have heard of is just people volunteering to grab WUs that have tasks completed during the challenge but haven't been validated yet.

(4) is it possible for me to specify greater priority for the GFN-Short units against the TRP Sieve units which will be in my queue over the next 24 hrs? I would prefer to get going with the initial GFN-Short WU once the window opens rather than wait 24 hrs for the TRP Sieve queue to clear so as to ensure the unit(s) completes on time.


Not exactly. But what you can do is set your queue (as mentioned above) to around 1.5 days (after selecting GFN-short CPU as the only sub-project to get tasks from), hit update on your client, then set the queue back to 0. That way it sees that 1.5 days is longer than your 24 hours of TRP sieve, and tries to fetch new work. The only work you've selected is GFN-short, so it tries to fetch 0.5 days of GFN-short. Of course, GFN-short CPUs are longer than 0.5 days, so it rounds up to "one task."

Do remember that the TRP sieves have a 4 day deadline, so you'll still need to complete your 24 hour queue in 4 days. If you don't think you want to do that (the challenge starts in 45 minutes as of this post), you can just abort all you TRP sieve WUs that you've queued up. Nothing bad will happen to them, they'll just get taken by someone else when they request a task off the server.

Yes, that's a VERY important point for newcomers:

DO NOT DOWNLOAD CHALLENGE TASKS BEFORE THE CHALLENGE STARTS!!!

Tasks downloaded before the challenge starts, or returned after the challenge ends, will not count in the challenge!

Thanks Michael and MeFigaYoma for the feedback and tidbits of advice.

Hopefully final question for this evening: I am not able to download a GFN-Short WU for some reason. Are there any restrictions on the server side in relation to the CPU's and their characteristics requesting work?

You have paused tasks that are PG. This is not PG stopping you, but BOINC. You cannot download new tasks from the same site you have paused tasks.

Anthony, your computer is running a 32-bit OS and has no GPU. You need a 64-bit OS to do this particular type of CPU work. You could install a 64-bit Linux, for instance. But you'd have to hurry - my Core 2 Quad at the same speed will take over 7 days per WU, and it's only an 8-day challenge!

Ken, a huge thanks for the diagnosis. I will clear the TRP Sieve cache on my other machine which has Win 7 Pro 64-bit and try it there. I will find 90 minutes to clone its disk as well for my 32-bit laptop you describe.

Many thanks!

No luck since it insists to ignore my preferences for now by downloading TRP Sieve. I had a similar problem about ten days ago when switching over from Sierpinski (ESP/PSP/SoB) Sieve to TRP Sieve after getting the silver badge for the former. The problem corrected itself about a day later.

I have tried a number of times just now but it still insists on TRP Sieve. No choice but to let it correct itself and as it did before.

Thanks once again for the help.

I just realized this is becoming messy: the 32-bit laptop must have TRP selected in the preferences so that it can grab a new WU every 55 minutes as an existing WU completes or otherwise it will remain dry. However, this means I cannot specify GFN-Short in the preferences so that the 64-bit laptop can correct itself and get the proper WU. :-(

EDIT: Please ignore ... I just played around with "Location" in the preferences to get around this problem. :-)

Are there results for a Nvidia GT 650M for GFN-short?
I specified to run it in OpenCL, as CPU resources are always in excess abundance on laptops.
It's estimating about a 40 hour run time, which is only about 25 hours ahead of CPU workunit estimates.

My newer machine with an AMD R9 M265X should only be a little faster.
But its looking like about 4 times faster for GFN at about 10 hours per WU

Then again, the older Nvidia card is several times faster at PPS-Sieve
So I suspect its mostly just obscure architectural differences
I can't test my 6770M to confirm, because either the GPU or the gutted switchable graphics drivers on that machine aren't compatible

9 Hours? that sounds about proportional as I'd expect your GTX 580 is at least 4 times faster than my Nvidia card.

What surprises me is how close my AMD GPU is to that speed

By that data sample, GFN either highly favors AMD cards, or perhaps the R9 265X has a much higher proportion of double precision hardware, therefore, despite its small size it's still somewhat competitive with larger Nvidia cards

NVidia is known to have lobotomized the floating point processing on their cards to avoid stealing market share from their Tesla brand (which are hugely expensive). The only NVidia "home use" card that can keep up with top-shelf ATI/AMD cards on Genefer is the Titan (not quite as hugely expensive).

Nice start to the challenge so far. Let's hope we can find a prime! It would be gargantuan, even if found in the GFN-Short project.

Saw an article recently about the design decisions in nvidia. The loss of DP performance in recent generations was interesting. In short, the process technology used hasn't really moved on recently, so they don't have any more total transistors to play with for more performance with each generation. Making it bigger would add to costs and heat, so they apparently chose to take away from the DP units and give it over to SP, which is what matters more for the main market of gaming.

AMD aren't immune to this either, although they might not have gone as far as nvidia. When looking to buy a multi use card, I went for the R9 280X as one of the highest DP performing cards for not a lot of money. The newer generation cards were supposed to be lower in DP performance. I haven't compared with others but I'm getting a short unit done in under 6 hours currently.

I'm exclusively a laptop person, but I experimented briefly with an AMD R9 285.
It seemed like a really good card, and still better at DP than most. The problem was it wasn't supported for much computing work yet, and that coupled with getting a motherboard that couldn't OC (which would have been $10 more), having to go back a few times for better cooling just to hold base clocks on PrimeGrid, AND the fact that my case didn't support a hard drive or disk drive with the cooler installed.

It seemed better just to scrap the entire build, take the money and wait for something radically new (DDR4, DX 12, better CPUs & GPUs, etc)

I know Hyperthreading isn't loved by many, but every computer I've owned in 5 years has been a quad core, 8 threaded Intel, and I'm very accustomed to pushing my systems and running things at same time as BOINC

I couldn't in good conscious build a machine that compromised on something such as that
I have a list of problems to avoid next time, and a much steeper price tag, for another day

I think spec wise, a Tahiti card is a great all-rounder, but I really favor low wattage cards that are stuffed with large amounts of utility, like unusually good double precision. a 250W card is too much.

I'm sure process improvements in 28 nm means newly manufactured R9 280s -could- be more efficient, unlike the laptop world, process improvements appear to be tuned to higher performance versions of that GPU, which command an even higher premium.

My older laptops used to ship with unlocked clock speeds, so the GPUs could often be clocked nearly as high as their desktop cousins, and remain stable without overvolting, because the more flawless chips were better suited for mobile systems.
It seems now if I want pure unrestrained performance I need to pay extra. For every little thing

Interesting about the NV DP stuff. The fact that my 480 and 580 can keep up (or exceed) with almost all the latest and greatest Nvidia parts in DP is one of the reasons I haven't upgraded yet. Though as a gamer, it will have to happen soon.

Those Tahiti cards are killer! The two 7950s I inherited from my dad will be about 6 hours too slow to complete a third WR task during this challenge.

I had forgotten how slow my video cards were, so I wasted over 15 hours on WR and had to abort then. I could have close to finished at least a short in that time on one, and withing a few hours on another one.

Looks like the GTX 770 is about twice as slow as the GTX 780ti. The latter may get done with two WR's in about 3 days.

31 hours into the World Expo Challenge - any CPU Genefer tasks complete ?

Completion rate for my CPU's computing two instances at a time (dual channel memory):

FMA3 3.0GHz Haswell/2133C7RAM = 75% in 25hr.
AVX 2.8GHz Ivy i5/1600C11 = 43% in 29hr.
SSE2 2.2GHz Westmere Pentium/1066C7 = 15.7% in 27hr.
GTX970 clocked at 1.5GHz finishes a short OpenCL in 8hr 03min. At 1539MHz the time is 7hr 55min. (PPSsieve @1565MHz/160W -- 30W more than Genefer) with ~1% BUS/MCU usage unlike Genefer's 67% MCU/ 41% BUS.

This is the first time I've GPU'd Genefer: I see OpenCL relies on a full CPU core. I'm running two CPU instances for maximum speeds instead of pinning the CPU at 100% - interrupts and memory contention happen infrequently. 3 CPU instances and 1 GPU on a quad (non-HT) will often miss - leading to longer total/CPU times.

On pace for 40+ challenge shorts: 24 from the 970 -- 10-12 by Haswell -- 6 by Ivy - 2 by Pentium.

I'm not sure how precisely to detect a potential memory bottleneck, and I was skeptical, however.. I have a sample that is unmistakable in its results

On twin systems with an Intel i7-4710HQ at 2.45 GHz (Haswell) and an AMD R9 265X
The first computer has a GPU and 4 CPU workunits running at the same time
The second computer has only the GPU running.

The second computer finished its workunit after 26.7 hours. while my own primary computer is on 37 hours and still only 88% done
I can't think what would account for this besides a GPU potentially underclocking, or some sort of memory bottleneck on the first computer


Is there some way to actually see this?
I expected a full load to be slower on the CPU side, but I am concerned that it would affect the GPU workunit so drastically

Ok I figured it out.. sort of. The GPU workunit said it was running, and the progress bar acted as though it were. But I'm highly skeptical it really was. Unless I have a 3rd GPU I don't know about.

The R9 265X showed few obvious signs of being under load. Its clocks were at idle 300 MHz, 0% utilization. very low (but some) thermal output. and BOINC said the entire time over 30 hours its CPU time was 00:00:01 which from running other programs seemed odd

Also odd was the running the CPU at full tilt without any thermal issues. They share a heat pipe, so that wasn't right..

Well. I crashed my PC trying to run GPU-Z. But I had the good sense to pause the workunits first.
The CPU ones are fine, but the GPU one has restarted from zero
The behavior is completely different, the GPU is hot and I can't run more than 2 CPU tasks alongside the GPU without going over the 95 C thermal limit

It worries me I should check on the other machines now.. >_>

Today, in a CUDA or OpenCL application, the CPU has to call the GPU functions. We can't download the program on GPU side and let it run. The execution time of one function call should not be too long otherwise the driver resets the GPU.
It is still a sort of graphical application that computes some consecutive images. The images are some huge numbers that are not displayed but the architecture is inherited from graphical design.

Genefer calls 7 functions per step (one multiplication). Typically one step takes few ms. Then thousands of commands are executed by the CPU per second.
There is a FIFO in the GPU driver and maybe in the GPU processor.

On NVidia, the size of one command in the FIFO is small and the FIFO size doesn't have to be limited (the driver blocks the CPU application when the FIFO is full). Then even if we see a CPU load at 100% (one core), the true load is very small (it is just a spinlock) and the GPU driver never waits for synchro. We can use HT to let the GPU driver execute commands.

On ATI, the size of one command in the FIFO is large and the FIFO size must be limited otherwise the GPU driver quickly allocate some Gbytes of memory! In Genefer, the max FIFO size is 1024 commands. Some synchronisation points are required, at least one per second.
The visible CPU load of the application is about 0% because the GPU driver uses some system synchros: but if no core is free, the GPU driver (and then the GPU core) may wait.
Because the command size is large, the GPU driver should copy continuouly some memory buffers (be careful of the hidden GPU driver load, drivers are some multithreaded applications).
Then a CPU core may (I didn't test it) be 'available' to let the GPU driver run at full speed.

The program SIV (system information viewer) shows interrupts/kernel/etc CPU usage.

Today, in a CUDA or OpenCL application, the CPU has to call the GPU functions. We can't download the program on GPU side and let it run. The execution time of one function call should not be too long otherwise the driver resets the GPU.

A 970 GPU only is nearly 1.5hr faster compared to [2]CPU+GPU. GPU/MCU/BUS usage for GPU only is the same when two CPU instances are computing at the same time.

Running GPU only - the time difference is surprising. At the same core 1539MHz clock: an OpenCL Genefer running on GPU only will finish in 6hr 20min instead of 7hr 55min (the CPU computing two instances.)

I don't believe the CPU was at fault here. I think BOINC started the OpenCL application, but the GPU was simply unresponsive, and it continued to count up on the progress bar, but wasn't actually doing anything,

The would explain why the CPU could run its 4 instances and not get too hot. It shares a heat pipe with the GPU, so ordinarily it throttles down if I try to run too much at once.
It was detectable, but just unresponsive. I'd never run Genefer before, so I dismissed it as normal.

But in hindsight, I think it's just a bug from the switchable graphics multi GPU configuration. The system powered down the AMD GPU and was unable to restart it.

After crashing/restarting the computer though, it's running as expected.
The GPU is showing signs of life, and I'm only running 2 of the CPU version to keep temps in check

The CPU version of Genefer uses 10 MB (short) or 40 MB (WR).
Then it continually clears the L3 cache.
A possible explanation is that the GPU driver uses more than 256 KB (L2 cache size) and less than 8 MB (L3 cache size).

Note that my 'explanations' are my understanding of GPU drivers. But I never seen their source codes then they may be wrong.

I have two CPU tasks running on my antiquated Duo Core 2.67 GHz P9600 CPU and it looks like about 210 hrs total run time per unit or about 2.5 days post challenge for completion. All of this unless the first few percentage points completed are not a true reflection of the total run time.

I would like to get the second laptop with same CPU going as well later today so as to have the silver badge out of the way between the four tasks if the challenge organizers can put up with a 3 to 3.5 day delay post challenge for these two units.

GFN-short tasks have a 19 day deadline, so feel free to run as many tasks as you like. It doesn't matter to us if they finish after the challenge.

If you look in stderr.txt, you'll see Genefer's internal estimate of how long the task will take. It's usually exceptionally accurate.

With any luck, I will have some fresh thermal grease in the mail early next week and which will cut my time down by about 35%. I sat down for some maintenance work ten days ago and only to discover after removing the old grease that I did not have enough replacement grease for a proper job. :-(

Running GPU only - the time difference is surprising. At the same core 1539MHz clock: an OpenCL Genefer running on GPU only will finish in 6hr 20min instead of 7hr 55min (the CPU computing two instances.)


That's actually very useful knowledge. It might be only 1.5 hours difference for you, but over a much longer run time, say, 24 hours instead of 6, running CPU tasks would mean an extra 6 hours, for a total run time of 30 hours.

It would be even more pronounced if you loaded all 4 cores instead of just the 2.
The question I have now is if there's a difference for faster (3 GHz and up) processors and slower ones (2 GHz and below)
A slower one might be less demanding on other resources

After nearly two days...

6692 short tasks have been sent out. 54% were sent to CPUs and 46% to GPUs.

15% of those tasks have been successfully returned, 51% are still in progress, and 33% of those were returned with some sort of an error.

Of those tasks that have been returned, over half (51%) have been validated already.

----------

For the n=22 World Record tasks:

726 tasks have been sent out. 44% were returned with an error while 56% are still in progress. I expect the first results from the fastest GPUs to start coming back within the next 24 hours.

-----------

For comparison, on an average day we do about 30 World Record tasks and about 300 short tasks.

(For those who are seeing statistics like this for the first time, the high error rates are expected. There's several ways that a computer can be misconfigured so that CPU tasks fail as soon as BOINC tries to run them, and LOTS of ways to break a GPU configuration. When that happens the computer will continuously download tasks, fail, and get new tasks from the server. A single bad computer can generate thousands of errors a day. It doesn't hurt the server, but it does skew the statistics by creating very large error counts.)

There is time discrepancy caused by a Windows time zone setting. Due to EST zone daylight savings windows will go back an hour if Auto setting is off. It will revert back an hour at random stewing BOINC reported runtimes. The stderr time is the proper time for tasks. BOINC will report an hour more than stderr. For those in EST zone check Auto for correct reporting.

Hi, i'm running 3*7970 (aka 280x) on amd fx6300 with 16gbt ram on win7 pro64.
And odly enough the second gpu does not run the genefer wu-s well, it starts to run the wu and runs it for some minutes on full load, then it stops running it at all and goes to idle, odly enough boinc manager shows that the wu is progressing, after some minutes boinc manager shows that the wu is no longer progressing but still running. After some minutes the gpu goes to full speed and full load and starts running the wu again.
All the time the third gpu is running the wu-s well at full load and full speed.
The first gpu was idling, for i keep it free for gaming and surfing the net via config file.

So i enabled the first gpu and disabled the second and both gpus are now running well at full speed and load. All gpus are asus 3 slot, first is 1,1ghz matrix the rest are non matrix 1ghz versions running at 1,1ghz.

So what gives with the second gpu? I have no idea. Milkyway runs well on the second card, on all three gpus that is.

An interesting caveat: the sensitive nature of Genefer causes dramatic GPU runtime differences. If Genefer is suspended in task manager - the process memory will remain active slowing up GPU+CPU runtimes. You have to manually end the task in process manager to clear the CPU from thinking tasks are there even though the CPU usage indicated 2 CPU = 1 GPU requires nearly 28-30% per Genefer process.

Even though CPU was "crunching" two tasks - the remaining 2 suspended tasks were active in the memory poll tricking the CPU cache into thinking there is 4 tasks plus one GPU to compute causing a slowdown.

Now that my cache now only has three active total tasks: 2 for CPU and 1 for GPU. My OpenCL Genefer GPU runtime to complete is 5hr 55min whichs includes crunching two CPU. (rather than 8hr with all four CPU "active" or 6hr 55min with two crunching and 2 suspended tasks in cache.)

For the fastest GPU or CPU runtimes: check to see if any suspended tasks are out of CPU memory pool. A 2hr+ runtime difference can be avoided if BOINC cache has only active tasks and no suspended tasks that are active in the memory pool.

There is time discrepancy caused by a Windows time zone setting. Due to EST zone daylight savings windows will go back an hour if Auto setting is off. It will revert back an hour at random stewing BOINC reported runtimes. The stderr time is the proper time for tasks. BOINC will report an hour more than stderr. For those in EST zone check Auto for correct reporting.

Maybe you're talking about something else, but the server always shows the deadline as one hour later than the BOINC clients do. It's a deliberate setting by us that started when too many hosts were missing deadlines by just a few minutes. That caused unnecessary jobs to be sent out to new hosts. BOINC times are all in UTC (what used to be called Greenwich Mean Time). When a clock changes on a computer from EST to EDT, the timezone offset changes from UTC-5 to UTC-4. The computer always knows the "absolute" (UTC) time. How well the BOINC client reacts to that I'm not sure offhand, but at most it would only affect tasks running at that point in time.

Now that my cache now only has three active total tasks: 2 for CPU and 1 for GPU. My OpenCL Genefer GPU runtime to complete is 5hr 55min whichs includes crunching two CPU. (rather than 8hr with all four CPU "active" or 6hr 55min with two crunching and 2 suspended tasks in cache.)

For the fastest GPU or CPU runtimes: check to see if any suspended tasks are out of CPU memory pool. A 2hr+ runtime difference can be avoided if BOINC cache has only active tasks and no suspended tasks that are active in the memory pool.


Hmm. I don't know if the CPU can be "tricked" like that. around a hundred processes are in memory at all times, but the CPU doesn't stumble over any of them. I'm not sure that's what caused your speed increase.

In any event, I'm trying a radically different strategy.
Instead of running 2 CPU WUs at highest clock speed I can, 2.45 GHz, I'm running 4 CPU + 1 GPU at 1.55 GHz and getting the exact same temps.

The theory going forward is that if slowing the clock speed 900 MHz allows me to double the tasks I'm running, it will outweigh the increased runtime.
It's also gambling somewhat that calculation speed may NOT scale in a linear fashion with clock speed
I believe I'm gaining more than I'm losing, but we shall see.

Nice idea: This strategy will test CPU/RAM memory contention and find out if more tasks at lower speeds will bottleneck. Genefer heats up DRAM more than LLR by a few C degrees.

CPU TDP accounts for the IMC/DRAM. Keep an eye on IMC/bank/DRAM temps and power usage - Genefer compute with C7 2133 dual channel (2 modules) IMC requires nearly 35W on a 3.0GHz quad Haswell. (60-130W for CPU/DRAM/IMC) A dual core Ivy Bridge IMC at 2.8GHz with C11 1600 is around 15W. (25-55W CPU/DRAM/IMC)

Lower CAS RAM shorten up Genefer runtimes. The higher the CAS (and slower RAM speeds) the longer the runtime. Larger LLR tasks also see faster runtimes when RAM is rated for higher speeds with a lower CAS.

Maybe you're talking about something else, but the server always shows the deadline as one hour later than the BOINC clients do. It's a deliberate setting by us that started when too many hosts were missing deadlines by just a few minutes. That caused unnecessary jobs to be sent out to new hosts.

The computer always knows the "absolute" (UTC) time. How well the BOINC client reacts to that I'm not sure offhand, but at most it would only affect tasks running at that point in time.

Thank you for the explanation. BOINC is reporting nearly an 8hr runtime rather than the stderr 6hr 55min for task: http://www.primegrid.com/result.php?resultid=621774242
This also happened for a task at GPUGRID. It's an issue with my system and not BOINC. Daylight saving setting causes BOINC to report an hour more if the clock switches when a BOINC project is computing. ( I have to restart my system for a daylight saving clock change to be permanent. Waiting for CPU Genefer to complete before I do)

Can't seem to get tasks, so I guess we're out, for NVidia OpenCL, at least the shorter tasks... The server status page doesn't give a breakdown of what tasks are available for what app, etc, just a total number available.... This started being an issue about a day ago...

OK, cuda is available, but openCL isn't. tbh I'd rather run the openCL app (better crunch times), and you'd rather we run it, due to the above post, but work availability doesn't seem to be supporting that now...

genefer_1048576_438490_7 and genefer_1048576_440474_3

The main page is showing several thousand units available. I suspect that your preferences might not be setup quite correctly. Double check to make sure that you have the OpenCL app checked for NVidia in the correct venue and that you have the CUDA app unchecked.

There's no such thing as "Cuda tasks" and "OCL tasks". If tasks are available, they're available. If you're not getting them, we need to figure out why not. The tasks are there waiting to be sent out.

The most common cause for people not getting tasks during a challenge is a "feature" of BOINC that prevents your computer from requesting work if you have any other PrimeGrid tasks suspended. People often do that so they can run the challenge tasks, but the way BOINC works that stops them from getting any new tasks. I'm not saying that's your problem, but it's a common cause.

Nice idea: This strategy will test CPU/RAM memory contention and find out if more tasks at lower speeds will bottleneck. Genefer heats up DRAM more than LLR by a few C degrees.

CPU TDP accounts for the IMC/DRAM. Keep an eye on IMC/bank/DRAM temps and power usage - Genefer compute with C7 2133 dual channel (2 modules) IMC requires nearly 35W on a 3.0GHz quad Haswell. (60-130W for CPU/DRAM/IMC) A dual core Ivy Bridge IMC at 2.8GHz with C11 1600 is around 15W. (25-55W CPU/DRAM/IMC)

Lower CAS RAM shorten up Genefer runtimes. The higher the CAS (and slower RAM speeds) the longer the runtime. Larger LLR tasks also see faster runtimes when RAM is rated for higher speeds with a lower CAS.


I'm unable to be certain the bottleneck was the RAM, but I think its most likely the cache on the CPU itself (L1, L2, and L3) The reason for this is because my laptops all either use 1333MHz at 9 CAS or 1600MHz at 11 CAS. The RAM many desktop users have is vastly superior, but seems to bottleneck at roughly the same number of workunits.

By lowering the clock speed, the CPU can use a much lower core voltage, the machine I'm writing from is only at 0.747 V, and this is regardless of how many cores or workunits are active.

The fastest Genefer task at the higher clocks, finished in about 65 hours. The current crop appears set finish around that time, perhaps as long as 70 hours, but, by running twice as many of them, will still pay off nicely.
My other two computers, using Ivy and Sandy Bridge CPUs are about 10 hours slower, but appear similar.

All I've done is lower my core speed & voltages enough to use all 4 cores within a much smaller thermal allowance than a typical desktop would have.
Even though I can't run my CPU as hot as a desktop, the lower speed results in a reduced demand for RAM & cache resources, so on the whole, my CPU is better fed for some types of workunits.
This means while I'm not the fastest, I'm not completely left in the dust either.

Hi All,
Could it be that the maxErr is set to low (too critical) ? ( 0.5000 > 0.4500)
Had several GFN-short tasks (to many) which failed due to MaxErr (622182614,622178105,622137335,..)
Downclocked and even replaced the (Dual) GPU-cards (in different computers) but no significant improvement.
Would be very usefull if a warning or indication is given when MaxErr occurs
and the sequence of 6 tries (retries and 10 minute pauses) begins.
(so GPU card can be replaced or even more downclocking has to be done etc)
Best Regards,
Walter Darimont (Aggie the Pew)

MaxErr exceeded may be caused by overclocking, overheated GPUs and other transient errors.

The 'true' error in this range is ~0.3 then the bound 0.45 is not the explanation.

Your errors are some hardware or driver errors.
I noticed that your driver was released in 2010, with OpenCL 1.0.
If you upgrade your graphic driver, you may solve your problem.

Well friends, the point of which CPU tasks newly started can no longer be completed in time for challenge points fast approaches. For most of my machines, that time has arrived.

Lets say your current crop of tasks is set to finish 20 hours before the deadline, and a new batch would take 40 hours.
Is there anything, any strategy, that would enable you to use those 20 hours for the challenge? =)

If you're running 4 threads, and each would have 20 hours available. That's 4 * 20 = 80 hours available divided by 40 hours (time per task) = 2 extra tasks you COULD squeeze in. If you have the 2 extra tasks downloaded, suspend 2 running task before 40 hours remain to start your extra tasks, and then resume then.

Then you have to micromanage your tasks to keep all your threads busy until challenge ends. Might be better to run 1 extra task, and not need as much micromanaging, and not risk losing a whole batch of tasks because you ran out of time.

You could download more w/u's and then pause the w/u's you're currently crunching, start crunching the new w/u's, then finish up the original w/u's.

I've completed 2 WR WU's and now back on the Shorts.
The two Shorts I've done have new highest err I've seen of 0.3750 and 0.4072 respectively:

Hi Roger,
Is err determined only by hardware (GPU and CPU) or also by application software (rounding errors)?
Got recently following stderr output in task 622137335:
maxErr exceeded for 671104^1048576+1, 0.5000 > 0.4500
MaxErr exceeded may be caused by overclocking, overheated GPUs and other transient errors.
(outcome : Computation error)

http://www.primegrid.com/result.php?resultid=622137335

How was maxErr setting determined (empirical, theoretical,..) ?
And is it the same for GPU and CPU?(and if not why?)

Thanks in advance.

It could be either. If B is too high, it's an algorithmic problem and a perfect GPU will exceed maxErr.

As long as we're not exceeding the B limit, the cause is always hardware error. That's what's happening here. Your GPU is malfunctioning.

It appears I will miss a GPU deadline by 10 to 15 minutes. I'm unable to overclock an R9 265X mobile card with any software I'm familiar with. If it existed though, the same die is used in much faster GPUs. I know it would be stable. But.
I'm pretty disappointed after so much careful planning, I will miss a task so close to finishing.

If no hardware malfunction then err is deterministic, i.e. you can rerun the same test and you'll get the same value of err.
err can change based on different hardware your running, i.e. CPU or GPU model.
maxErr = 0.450 and that is fixed. You don't want to head towards 0.5 because then the result (probable prime or no prime) is random.
Different algorithms can also result in different err for a given test, given the same hardware.
I view heading towards a b-limit as an interesting time. No prime is missed.
Below is err from Short units I was doing up until just before the challenge on HD7970 GPU using OpenCL:

The two Shorts I've done have new highest err I've seen of 0.3750 and 0.4072

CUDA err rates are close to 0.4500 absolute limit. OpenCL GPU err currently at >0.3750 while AVX/FMA3 err = >0.3000

(6113937 digits) task 'b' = 677180 --- sent as a 3rd checker --- wuid=432062758:
GTX780 CUDA err = 0.4453 (numerous maxErr exceeded prompts)
GTX570 CUDA err = 0.4063 with CUFFT/Runtime API errors.

Highest OpenCL err I've rendered on a GTX970 = 0.3750 for 'b' 686032. (6119851 digits)
-AVX/FMA3 'b' 677920 err = 0.2969
-Nvidia Maxwell OpenCL 'b' 674096 = 0.3750
-Haswell FMA3 'b' 665348 = 0.2891
-Ivy AVX 'b' 642006 = 0.2656 (6089647 digits)

I view heading towards a b-limit as an interesting time. No prime is missed.

As do I - Genefer is my favorite sub-project. (Genefer works a CPU tad harder than LLR.)
We're now into last 3% n = 20 candidates. For the month of April: close to 7000 short Genefer tasks will be completed.
Over 5k candidates remain before CUDA/OpenCL/AVX/FMA3/SSE2 application 'b' limits.

Are Haswell N = 21 task runtimes (12e7 digits) similar to Haswell SOB? (400K seconds)

I selected the WR length for this challenge as you requested. However it looks like my GTX 560 is just not fast enough to finish any of those workunits before the challenge ends. I plan to let the only workunit downloaded finish after the challenge ends, though.

With a little under 1 day left on the clock, it's time for the usual end of challenge reminder :)

At the Conclusion of the Challenge

We would prefer users "moving on" to finish those tasks they have downloaded, if not then please ABORT the 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 a 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.

Big ouch. BOINC could not read my PrimeGrid account file after a blue screen and threw away all the workunits and their slot directories. I was able to recover the slot directory of one GFN-WR and copied the workunit and result info from another machine's client_state.xml. Of course, I changed the WU name and command line so that the WU could complete successfully. But I forgot to change the name of the output file, so this is what happened after all the work: http://www.primegrid.com/result.php?resultid=622355745 :(

First of all, the 'b' limit on the GeneferCUDA program is LOWER than the 'b' limit on GeneferOCL, so I STRONGLY RECOMMEND that everyone who is still using GeneferCUDA switch over to using GeneferOCL. When we start sending out tasks close to the GeneferCUDA 'b' limit I will be disabling the GeneferCUDA apps, and if you have only GeneferCUDA selected you will no longer get GFN-Short tasks. Even if you're running with app_info you should switch because the GeneferCUDA app will start failing with "computation errors" due to the 'b' limit.


We have just passed the threshold where it's probably no longer safe to continue using the CUDA app. I have disabled the CUDA app for GFN-Short tasks; no more will be sent out.

If you have CUDA selected, you will not receive any more GFN-Short tasks. Please select the OpenCL app for Nvidia instead.

The card GeForce GTX 770 @ 1333 Boost + Core i5-4690K @ 4.6GHz only counts GeneferCUDA - no errors. When I used GeneferOCL to even reference frequencies calculations were error. For GeForce CUDA it is stable.

What I like about Challenges with more than one sub-project (i.e. GFN-short & GFN-WR) to crunch is the figuring out the best strategy for a given machine or machines. This Challenge in particular is interesting because the GFN-Short can be crunched on either cpu/avx or NVIDIA OpenCl. Michael has given us basic guidelines to follow earlier in the thread.

I liken it to an F1 race - should I start out on prime or option tires (which project on the cpu or gpu) and when should I box (return to the pits) to switch projects when it looks like I won't be able to finish a larger task before the end of the Challenge?

The challenge is over! Thanks to everyone who participated. Here's the (somewhat late) final statistics:

Challenge: World Expo
App: 16 (GFN-Short)
(As of 2015-05-02 12:39:01 UTC)

21992 tasks have been sent out. [CPU/GPU/anonymous_platform: 9889 (45%) / 12015 (55%) / 88 (0%)]

Of those tasks that have been sent out:

8462 (38%) came back with some kind of an error. [3459 (16%) / 4997 (23%) / 6 (0%)]
10741 (49%) have returned a successful result. [4382 (20%) / 6285 (29%) / 74 (0%)]
2051 (9%) are still in progress. [1731 (8%) / 317 (1%) / 3 (0%)]

Of the tasks that have been returned successfully:

768 (7%) are pending validation. [105 (1%) / 654 (6%) / 9 (0%)]
9863 (92%) have been successfully validated. [4253 (40%) / 5545 (52%) / 65 (1%)]
62 (1%) were invalid. [10 (0%) / 52 (0%) / 0 (0%)]
48 (0%) are inconclusive. [14 (0%) / 34 (0%) / 0 (0%)]

The current leading edge (i.e., latest work unit for which work has actually been sent out to a host) is b=692158. The leading edge was at b=664214 at the beginning of the challenge. Since the challenge started, the leading edge has advanced 4.21% as much as it had prior to the challenge! (When task size is considered, that's an increase of 4.53%.)

Challenge: World Expo
App: 17 (GFN-WR)
(As of 2015-05-02 12:39:02 UTC)

1785 tasks have been sent out. [CPU/GPU/anonymous_platform: 0 (0%) / 1778 (100%) / 7 (0%)]

204 (11%) are still in progress. [0 (0%) / 202 (11%) / 2 (0%)]

Of the tasks that have been returned successfully:

0 (0%) were invalid. [0 (0%) / 0 (0%) / 0 (0%)]
6 (1%) are inconclusive. [0 (0%) / 6 (1%) / 0 (0%)]

The current leading edge (i.e., latest work unit for which work has actually been sent out to a host) is b=48390. The leading edge was at b=46982 at the beginning of the challenge. Since the challenge started, the leading edge has advanced 3.00% as much as it had prior to the challenge! (When task size is considered, that's an increase of 3.23%.)

Considering the size of these tasks and how difficult they are to run, the participation was fantastic! Roughly five times the normal number of GFN-Short tasks were processed. We also did about three times the number of GFN-WR tasks as we normally do, which is really impressive because many computers simply can't do GFN-WR tasks in 8 days, or can't run them at all.

Great job everyone!!!

The cleanup starts today for the challenge. It will be a long one! It will probably take between 2 and 4 months.

Cleanup:

1-May: World Expo: 1224 tasks outstanding; 1131 affecting individual (204) scoring positions; 685 affecting team (41) scoring positions.
2-May: World Expo: 1001 tasks outstanding; 908 affecting individual (188) scoring positions; 544 affecting team (39) scoring positions.

what does cleanup work actually mean in regards to scoring positions?
Is it to essentially confirm the results currently on the leaderboard? (as in, credits are removed in a task is found invalid)

Or is there potential for rank gain from these tasks?
If so, is that ONLY for people who finished the task within the 8 day challenge window
Or is there incentive for others to intentionally seek out cleanup work post challenge?

what does cleanup work actually mean in regards to scoring positions?


Challenge points are awarded immediately upon receipt of the result from your computer. We do not wait for the tasks to be validated against a matching result. This is done so that people have a good idea of where they stand on the leaderboards.

However, we do not want invalid results (intentional or otherwise) to count in the challenges, so before the challenge is considered complete, we wait for most of the tasks to be validated. If a result passes validation against a matching result, nothing changes. However, if the result fails to validate against a matching result (i.e., there was a computation error), then the challenge points for that task are rescinded and you may drop in the standings.

In the cleanup phase we're waiting for those tasks to validate as the wingmen's tasks trickle back in. Note that we don't necessarily wait for EVERY task; it's only necessary to wait for tasks that would change the order of participants on the leaderboards should those tasks fail validation and therefore result in a reduction of challenge points causing you to be in, for example, third place instead of second place.

Or is there incentive for others to intentionally seek out cleanup work post challenge?


No incentive :)

However, I can think of several "personal incentives" for running cleanup tasks:

1. You want to finish up that badge you almost got during the challenge
2. You have your own tasks from the challenge waiting for validation, so you would like to help your fellow competitors get their tasks validated (i.e. helping each other since you can't help yourself)

And when cleanup is almost over, with 20 or so tasks left, and it becomes rare for a cleanup task to actually be available in the server queue since most of them are currently being crunched:

3. You randomly check the homepage and see the elusive

*** 1 task, 1 affecting scoring positions, of Year of the Sheep Challenge (SOB-LLR) cleanup work are currently available! ***


you quickly change your project preferences to SoB and set your queue to a day, all in hope of getting the task before that guy with the Atom with nothing checked in his project preferences. Sort of "for the good of PrimeGrid."

Michael,

You have potentially two less tasks to worry about. Following a marathon session of approximately 260 hrs, both of my work units completed successfully a few hrs ago.

I was very much worried about a possible computation error but thankfully no such heartache.

The damn thermal grease purchased from eBay has yet to arrive. It is 36 days and counting. :-(

Hello,
I will miss him a few hours to finish tasks. I had a machine failure. There is no miscalculation and island would be a shame not to complete the eight almost finished tasks.

It takes me between 4 and 8 hours. Total time over 400 hours.

I wanted to know if this work would yield results. Calculating task durations is false.

I assume you are asking if tasks submitted after the deadline will give BOINC credit. Yes, on PrimeGrid (other projects may be different), any task submitted while the workunit is still in the database will give credit. The workunits are not deleted from the database any sooner than one deadline-length (19 days for GFN-short, 21 days for GFN-WR) after the workunit is fully validated, and for challenges specifically (assuming you are talking about World Expo challenge workunits, which, looking at your computers on your account page, you seem to be), no workunit is deleted until after the challenge cleanup is over. That will likely be another few months.

You will not get any challenge credit since the challenge is already over. To count for challenge credit, tasks have to be requested and returned during the challenge time frame. You will still receive normal BOINC credit, as you would with any other task, even if you submit it after the deadline.

Note that if the workunit has not already been validated (i.e. two tasks submitted with matching results), when your task passes the deadline, a new task will be sent out to a different computer. Depending on whether that new computer's owner checks their results page, they may abort the task when they see you have completed it, or they may not see and continue work on it, effectively wasting computing time. For this reason it is detrimental to regularly submit tasks after the deadline passes, especially with the longer sub-projects (GFN-short on CPU, GFN-WR, SoB, etc), as it has the possibility to waste significant resources.

Good luck with Google Translate.

How long do we have to wait for some one to finally return them without errors. It looks like mostly errors since late April? Just asking.

As long as it takes.

They are randomly given out. If it errors, or times out it goes to another person and so on. No easy way to tell.

Although looking at the two tasks, the first one in the list is on a machine that has pushed back several reliable WR units over a period of time with a turnaround time of 5-7 days. Looks like we could have that one done by 30-June.

Second one is on a host that shows no WR complete. Somewhat similar card as the first box and has all reliable CPU work, but no shown finished GPU work (only one abandoned one) and is continuing to do work, which some were returned yesterday. It looks like it works part time and does other GPU work. So no telling a timeline on that one.

Woot, the last WR validated. Not bad for such long units, starting mid/end April ended beginning of July.

Congrats to all the challengers.

After a fairly short (relatively speaking) cleanup, the World Expo Challenge is over!

The top participants in order are Ross*, zunewantan and RaymondFO*.

Looking at the teams, the top teams are Sicituradastra., Czech National Team, SETI.Germany.

Although we advanced the search a fair amount, we haven't been lucky enough to find a prime during the challenge. Who knows what the future will hold though :)
