Welcome to the Father's Day Challenge
Father's are awesome. They can fix everything, they know everything and they're always there for you. That's why there's a day just for them. Just like most other men, regardless of being a parent or not, they like gadgets. Especially new gadgets. With the imminent go-live of a new subproject on PrimeGrid we would now like to invite everyone to participate in this Father's Day challenge on the SR5 subproject. The challenge will run from June 15th 2013, 18:00 UTC to June 18th 2013, 18:00 UTC.
This project is an extension of the original Sierpinski/Riesel problems (SoB/TRP). It is attempting to solve the Sierpinski/Riesel problems for base 5 by determining the smallest Sierpinski/Riesel numbers. Therefore, primes of the form k*5^n+/-1 are being sought for even k's.
A distributed effort is currently ongoing in support of the project. More information can be found in the mersenneforum.org Sierpinski/Riesel Base 5 thread.
To participate in the Challenge, please select only the SR5 (LLR) project in your PrimeGrid preferences section. The challenge will begin June 15th 2013, 18:00 UTC and end June 18th 2013, 18:00 UTC. Application builds are available for Linux , Windows and MacIntel 32 bit and 64 bit. CPU's with AVX capabilities will be significantly faster than the ones without, as this instruction set allows for more computing power.
ATTENTION: The primality program LLR is CPU 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 computer. WU's will take about 1.5 hour on fast/newer computers and 4+ hours on slower/older computers. If your computer is highly overclocked, please consider "stress testing" it. Sieving is an excellent alternative for computers that are not able to LLR. :)
Restricted airflow is one of the primary reasons for overheating. Take the time to monitor the fans and review the dust buildup. Please, please, please make sure your machines are up to the task.

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 June 15th 2013, 18:00 UTC and received BEFORE June 18th 2013, 18:00 UTC will be considered for credit. We will use a similar, but not the same, scoring method as for BOINC credits .
Therefore, each completed WU will earn a unique score based on its n value. The higher the n, the higher the score. This is different than BOINC cobblestones! 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.
For details on how the score is calculated, please see this thread.
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 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. :)
Best of Luck!!!
Sierpinski Base 5 - The smallest even Sierpinski base 5 number is suggested to be k=159986. To prove this, it is sufficient to show that k*5^n+1 is prime for each even k < 159986. This has currently been achieved for all even k, with the exception of the following 44 values (as of 30 May 2013):
k = 6436, 7528, 10918, 24032, 26798, 29914, 31712, 36412, 37292, 41738, 44348, 44738, 45748, 51208, 55154, 58642, 59912, 60394, 62698, 64258, 67612, 67748, 71492, 74632, 76724, 77072, 81556, 83936, 84284, 90056, 92158, 92182, 92906, 93484, 105464, 109208, 118568, 126134, 133778, 138514, 139196, 144052, 152588, 154222 Riesel Base 5 - The smallest even Riesel base 5 number is suggested to be k=346802. To prove this, it is sufficient to show that k*5^n-1 is prime for each even k < 346802.

Robert Smith originally presented the idea of a Sierpinski/Riesel base 5 search on 17 September 2004, in the primeform yahoo group. Using {3,7,13,31,601} as the covering set, he proposed that k=346802 is the smallest Riesel base 5 number. Shortly afterwards, Guido Smetrijns proposed that k=159986 is the smallest Sierpinski base 5 number.
After doing most of the initial work himself, Robert posted in the mersenneforum.org on 28 September 2004, and thus, the distributed effort began. Other principle players in the development, management, and growth of the project are Lars Dausch, Geoff Reynolds, Anand S Nair, and Thomas Masser.

I believe it is 1.5 hours on a newer CPU and about 4 on an older one.

If it were live, I'd expect the "average CPU time" to show around 3 hours.
The average time, considering fast CPUs, slow CPUs, and fast CPUs with HT on, seems to be real close to the speed of a Core2Quad Q6600. Adjust your own expectations accordingly.
Expect about 150 credits per task.

On my I7 at 4HGz it is around 42 minutes
And for credits: If I for 1900 seconds got 100 credits, for 2520 I will get 150 credits.
Nice news!

I expect my internet bandwidth to be much less than usual during this challenge. Therefore, what is the approximate size of the downloads required for the first workunit, and what size should be required for the later workunits? Also, what is the approximate size of the uploads required for each workunit? | |

The uploads are smaller than this message. The per-task downloads are even smaller. The only bandwidth you have to worry about is when the programs get downloaded the first time you run SR5.
Since the LLR program for SR5 is the same as the LLR program used in the other projects. I'm fairly confident that BOINC won't download it a second time. So, If you've already been running LLR, nothing large at all needs to be downloaded. Other than that, boinc's gong to use less bandwidth than you're currently using to read this forum.

I hope I am proven wrong but I have reservations about the wisdom of having a challenge with a sub project that has not been run long enough to have the software bedded down on the many systems of hardware used here.
I see the potential for a major mess if some platforms have problems.
Just how confident is the management of everything working as well as normal for the challenge?
Second question -- will this be another LOOOONG clean up challenge? We have not got rid of the Woodalls quite yet!

First off, it' not unproven software. All LLR use the same software. It's just different sized WUs that are being run in each of the LLR projects to try and prove theories on certain sets of numbers. I am sure there is a 99.999999999% confidence the project will run as advertised, unless the tables are messed up, but since they are starting the work a day early they will know that immediately.
Second question -- will this be another LOOOONG clean up challenge? We have not got rid of the Woodalls quite yet!
With these units being only about 3.5 hours long, clean up will be able the same as the PPS or SGS was.

I am as confident as if it were any other LLR challenge, as it will use exactly the same piece of software.
Second question -- will this be another LOOOONG clean up challenge? We have not got rid of the Woodalls quite yet!
I am going to go with a somewhat careful "probably not". As the average run time will be something like 3.5 hours, rather than 70+ hours clean up should be done fairly quickly. That is, if there arent going to be a gazillion 3-second wu's. But even then it would be quicker than the previous challenge.

I'm fairly confident that nothing will break that we can't fix. As others have said, it's the same LLR program that we use in lots of other projects, so I don't foresee any problems there.
The newness -- and the reason I'm going to be not quite as certain as the other posts -- comes in the handling of base-5 tasks on the server. We think we changed everything that needs to be changed, but it's possible that we'll miss something.
That's why, before we go live, we're going to test work generation on the test server to make sure we're generating work and sending it out correctly. If we're really confident, we might even skip that step since we have a day between going live and the challenge. Regardless of where we test it, it will be tested before being released to the public.
The other 'risky' part is all the processing that happens after completed SR5 tasks are returned. There's a lot of moving parts there, and while I'm quite confident we'll have SR5 tasks going out and getting processed correctly, it wouldn't surprise me if a few things break after the tasks come back. That doesn't worry me a whole lot, as those kinds of problems are easily correctable.
Just how confident is the management of everything working as well as normal for the challenge?
Bottom line is, I'm very confident that the challenge will go very smoothly. When you contrast the minor problems that might occur during this challenge with the huge problems we used to have merely keeping the server running under the load, I expect this to run smoother than most short-task challenges have gone in the past.
Second question -- will this be another LOOOONG clean up challenge? We have not got rid of the Woodalls quite yet!
SR5's will start out having a deadline of 3 days, the same as PPS, PPSE, and SGS. It's the task deadline that usually determines how long a cleanup takes.
SR5 tasks will start off with durations of about 3 hours or so, which is much shorter than the Woodall duration of just under 4 days (with a deadline of 14 days.) It's possible that SR5 tasks will take longer to crunch at the end of the challenge, depending on how much participation we get.

Currently we are not able to select the challenge project in our prime grid settings (no checkbox against the sub-project)
Is this simply an oversight / when will the sub-project be made available for selection?
It is nice to be able to run some tests prior to a challenge start to ensure one's configuration settings are correct. ;-) | |

It is nice to be able to run some tests prior to a challenge start to ensure one's configuration settings are correct. ;-)
They're short tasks and you've got 24 hours before the challenge tests. Unless you're running an ancient 32-bit CPU (which I am, by the way), that's more than enough time.
Furthermore, it's an LLR test like PPS, etc., so there's no configuration settings, downloads, or anything else. Just select it and crunch. If you're wondering whether to run with HT on or off, or whether to leave a core or two idle, you should run in the same configuration as you do with PPS.

Which is what, do or don't? :)

Everybody's system is different, so there's no "one size fits all" answer.
The best answer is to try it both ways, and use whichever works better for you. If you don't want to do that, my recommendation would be to do it the same way you normally crunch PPS or PPSE or SGS LLR.

Based on my quick back of the Excel math, I'm getting (approx):
HT on: 13.36 cred/min
HT off: 12.525 cred/min
HT ho!

Bingo. We' still finalizing last month's challenge, so those stats pages were still linked. I didn't remember to change them until about 20 minutes after the challenge started. (Usually they're changed well in advance.)

Looks like I'll be 5-6 Hr's late getting on the Board. I don't know why there is a 10 min Difference in the Time the Challenge starts and my Computers here in Michigan. All I can think is I downloaded the Wu's before 2PM my Time even though the Challenge had been running for over 10 Min's already. I guess in the Future I'll have to wait 30-60 Min's after the Challenges start to insure I don 't download the work to soon.
I just went thru my Box's and Aborted any ready to run Wu's to get new ones, I let the ones already running run to their finish. If I don't get on the Board in 2-3 Hr's then something else is wrong ...

Progress:
In the first 9 hours of the challenge, the leading edge has advanced from n=966K to n=1053K, an increase of 73K. (14K worth of 'n' from 970K to 984K was crunched before the challenge started, so the challenge advanced n by 73K even though 1053-966=87.)
By comparison, in the 5 day (120 hour) PRPNet challenge that ended yesterday, n increased from 946K to 966K, and increase of 20K.

I have completed many wus and still no score showing... I downloaded the wus after 1800 UTC, but checking on the results, the tasks are showing as being sent 12 hours earlier...what gives? Have now aborted and re downloaded after 13 hours in, see if this helps... | |

Where are you, and at what (local) time did you originally start getting tasks for the challenge? Guessing from your IP address, the challenge should have started at 8 PM (20:00) Saturday (your local time) assuming Daylight Saving's Time is in effect where you are, and 7 PM (19:00) if it's not. Is that when you started downloading tasks for the challenge? (Unless I've messed up the time zone calculations in my head. Again.)
It's hard to tell from looking at your tasks which ones you intended to be in the challenge and which ones you may have intentionally been running to get a badge prior to the Challenge.

(This isn't necessarily for you, as I suspect you already know this, but it may help others.)
Also, be aware that the BOINC client shows times in LOCAL time, and the PrimeGrid website shows time in UTC time. That's pretty obvious if you're on the other side of the planet, but not quite as obvious when the times only differ by an hour or two.

But when the Projects Clock say's the Challenge has started shouldn't you be able to download the Wu's & have them count no matter what the Local Time is. If that isn't the case & you have to wait 2-3-4 Hr's before the Local Time say's 2PM like yesterdays Challenge start Time your at a disadvantage ... IMO

As is noted in many places the count down clock uses your computers time settings. So if you set your time to June 19th now, the challenge will show as over even though it isnt.

The countdown shows the time according to your host clock and not according to the server clock. If the host clock is running faster or slower than the server, which happens a lot for example on virtualized hosts (VMware ...), than it doesn't show the correct challenge start and stop times. By the way, the server probably runs on Internet time (NTP) or at least close to it.
The UTC time for the server shown on the PG frontpage (slightly left and above of the countdown clock) is the only relevant clock in regard to valid download times or not.
I always check shortly before a challenge if my hosts shows the same time as the PG frontpage to avoid any problems there. If the clock of the host differs i synchronize the host to internet time (date and time settings on Windows) | |

The clock display is based on the clock on YOUR computer -- if your clock is off, or if your timezone settings are off, the countdown clock will show the wrong time. If you're late to an appointment because your watch has stopped or is set to the wrong time zone, you don't blame the person you're meeting with, do you?
The instructions in the first post of every challenge -- including this one -- do say to check the server clock time, and that the countdown clock is based on your own computer's time. (BTW, it's exceptionally difficult to having a running clock that's based on a time other than your own computer's clock. That's why nobody does it that way. If it were possible to do it, we would.)

Someone is clearing SR5 WU's in exactly 600 seconds (no runtime)..
IF something is wrong, then it would probably affect the scores in the current challenge

You'll see that in several LLR projects -- it's a double check of work done outside PrimeGrid which was only single passed.
We have lots of residual information from a lot of sources, and if we happen to already have residuals for some numbers we're testing, we use them. That way we only have to crunch that number once instead of twice.
At some point in the future, we're likely going to double check all the SR5 work done in PRPNet -- and the original PRPNet tests will show up like that, too.
By the way, we maintain a huge database of residuals that come from all sorts of sources. EVERY LLR task that the system generates is checked against that database. If we have a residual for that candidate, we only have to send out one task rather than two, and use the existing residual as the wingman.

Challenge Status:
We're 25 hours into the challenge, and it's off to a fantastic start! In the first 25 hours:
* It looks like two primes have been found, but we're waiting on the double checkers.
* 213,774 tasks have been sent out.
* The leading edge is now n=1073K. At the start, N was 966K, but some of the intermediate candidates were processed prior to the challenge.
The following numbers also include the 24 hours prior to the challenge start, since SR5 was opened:
* 105,190 candidates have been sent to at least one computer for crunching.
* 23,578 candidates have been completed and double checked.
* 8 People have 
* Another 162 have

Any suggesitons?
I have like 25 pages, that's ~500 tasks waiting for validation and ~750 already validated which I consider quite OK.
My oldest WUs still waiting to be validated was completed on 13th. Next task "Error while downloading", another "Error while computing", last error was "Timed out - no response" after 3 days.
Next task was resent 4 minutes (!) after it timed out and is (still) in progress.
I don't thing there is much more we or server can do...

This can be attributed to two things.
1) Short units
2) Very fast system
Because you've got a very fast system you can turn workunits around in 45 minutes to an hour, where the average time over all the participants is about 2.5 hours. So in the time it takes you to crunch 4 workunits (on each core) the average participant can only return 1.
As the workunits are short, the cleanup afterwards will be so too I expect :)

Main problem is set of 10 days cache in Boinc manager. And many, many users set maximum cache... But since dead line is in only 3 days, many WU must be resent because they expire before then can be processed.
So it will be very good if admins set maximum of let say 80 WU per host. Even on fastest CPU it is about one day of work....

I can't set that on a per-application basis. We need that number to be larger for people crunching PPSE, etc..
People might not like this answer, but long lists of pending tasks isn't a problem. It's the way the system is designed to work. Nothing will be fixed because nothing is broken.

I have a lot more in pending credits than credits on the board. I noticed that the PPS were long to run and even longer running in pending(as no one picks up) for the most part. When I looked further I could see a lot of dumps of the PPS. It takes more time to received a confirmation on a PPS unit than on a Ski unit; chances are that the PPS will not be confirmed until after the contest. So why even bother with the longer units. There are no prizes for those who take the time to crunch them, doubly true if not validated until after the contest. In fact (duh) you are likely to be penalized for doing longer credits. I still have 2 Wood wu from a month and a half ago waiting to be validated. If big entities come to rule the roost Prime will find that the majority of the hens have left. While they might have a few big producing laying hens, they will have lost the majority of the flock and eggs. | |

how so? Presuming your WUs are valid then you will get the credits eventually and as you say,
There are no prizes for those who take the time to crunch them
at least as far as credits are concerned.
Of course you're ignoring the fact that the only way to find a giant prime is to crunch the longer WUs.

Please quit the bitching and moaning about your pending queue!
If you don't like how long it takes, make another account go and buy some more computing power and get crunching harder and faster yourself in the hopes of becoming your own wingman!
There's exactly nothing we can or will do about the current queue as there's absolutely nothing wrong, awry, broken, erroneous, fallacious, inappropriate, malfunctioning or damaged about it. If you want instant credit, go to a project that doesn't do BOINC and/or doesn't care about the validity of their results.
Now, with regards to your question why you're not as high up on the stats as you expected Sunbadger* I suggest you buy a pair of glasses and read this, which is above every challenge.
Only work units issued AFTER June 15th 2013, 18:00 UTC and received BEFORE June 18th 2013, 18:00 UTC will be considered for credit.

Badger,
Honestly, I have no clue what you're talking about with PPS. As far as I can tell, most of your pending tasks are SR5. Considering ALL challenge tasks have not yet reached their deadline, this is completely normal. Lots of people download huge caches of work (not a good idea when you're hunting for primes, in my opinion), and lots of people do not have <report_results_immediately> enabled (also a bad idea when you're hunting primes), so until the 3 day deadline passes, having pending tasks is simply the way it is. Nothing can be done about it, at least nothing that won't cause much bigger problems than it solves. There's no reason people have to return results quickly, although it's to their benefit to do so.
This is nothing new -- any boinc project that requires double checking has been this way since the beginning.

I'll add to Michael et al above.
PENDING TASKS ARE GOOD. They are the ones who will get the prime finder status if there is one going, not the planning challenged fool you are waiting for!!
OK you may be calling them something else but you know who I mean.
There are 2 ways not to have to wait for the wing man (as I said a few challenges ago) :-
1) Always be the wingman, you get the credit instantly but are only ever the checker.
2) error out, instant answer but no credit or primes.
Although method 2 seems to be very popular, I prefer to be patient.

You know, I forgot about that. Yes, I'd much rather 100% of my tasks were sitting waiting for a wingman to finish.
We've already found three primes during the challenge -- and for two of the three, the wingman has a HUGE cache of tasks and will likely return them days after the first guy/gal did.

Please quit the "replace" about your pending queue!
Dear Mr. Cow - I have quite a few pending jobs and while I didn't really want to say anything I am curious as to when they might be done. I'm not even sure I know what a "pending queue" is. Is that where the pending jobs are? Why is it called a queue if they are "pending? Doesn't that mean that the jobs are not in line yet but waiting to get in line? So, as I asked at the beginning, please go look and see when my jobs will move from pending to done or whatever the next step is and get back with me as soon as you can.
Cheers from a friendly rat :)

My £0.01999999 worth...
Pendingness is patience yes. But the good thing is you have the work in the bag. I've just had one of my two final GFN WR's 'resolve', meaning I can just continue to sit back & watch it tip over into sapphire!
Just be patient... & you'd rather be the prime finder wouldn't you? | |

I didn't think that pending work for a challenge were of any concern as you are awarded points on how many work units you return, validated or not.
Your own personal totals will be credited with real world points as each work unit then gets validated, it's not an issue really, you will get your points and a lot quicker than I will over at RNAWorld, I have been waiting most of this year for some work units to be reissued to someone so I can actually get a validation.
All seems to be running fine over here and the responsiveness of the server during the challenge has been excellent.

That's really impressive! Thanks for the updates.
Is it possible to estimate how many flops we've been delivering?

Need some big numbers for that.
Gigaflop =1 billion floating point operations
Teraflop = 1000 gigaflops
Petaflop = 1000 teraflops
Exaflop = 1000 petaflops (or a billion billion floating point operations)
My best estimate is that so far we've sent out tasks representing 8.1 exaflops, not all of which will be processed and returned. About 4.3 exaflops worth of tasks have been sent out, processed, and returned during the challenge so far.
We're about 59 hours into the challenge right now, so based upon the number of tasks that were returned, that would be about 20 teraflops per second. That number is actually too low, because it's not counting tasks that are out there being processed (or already have been processed) and have not yet been sent back to the server.
Using the higher number of total tasks sent out, we get a figure of about 38 teraflops per second. The actual number should therefore be somewhere between 20 and 38 TF/s.

Thank you Michael!
That's impressive but it wouldn't qualify us in the top500 supercomputers. I thought we we delivering a bit more than that especially with the boost cncr04s has given us.
Though with all GPU and CPU power on PrimeGrid and PRPNet we should qualify quite high. | |

Remember to ask me that question again the next time we run a PPS-Sieve challenge and we're running on GPUs. :)

According to BOINCstats (presumably based on a crude scaling of RAC), we are currently putting out 537 TFLOP/s, which would place PrimeGrid around 50th place on the current top500 list. However, the measure used for the top500 is based on running Linpack (which can achieve quite high percentage of peak flops e.g. 80%+), and LLR will be much lower than this. Another interesting comparison would be to add up all the peak FLOP/s of all CPUs and GPUs working on PG and compare that instead, and I suspect we might end somewhere a bit higher up the list!

With about 6 hours left to crunch we would like to request the following:
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 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. :)

I'll stick around and help cleanup, since I am working on badging up. What an interesting challenge, bringing in a new project just about 24 hours before and seeing the units grow so quickly and some nice primes being found. My luck hasn't been very good in finding one currently, but we have a few hours left.

My luck hasn't been very good in finding one currently, but we have a few hours left.
The original plan was to go straight from the the PRPNet challenge and launch SR5 here with no delay at all and go straight into this challenge, but we needed to give people time to access their computers to switch from PRPNet to BOINC.

As this nears it's end, I will state that this seemed to be an awesomely successful way to run this new project on PG. Bringing in as challenge project, seeing the great outcome of primes (5 so far, dang none for me, yet) and the admins keeping a close eye on this since it was a new project has really made this an awesome few days.
Congrats to the prime finders and wingpeople. Congrats to all the shiny new badges (my silver came in before the end), and everyone who participated.

Hei all.
To run long wu`s has never been a problem if its a reason behind it. ;-))
Though..right now I have one wu left, it has been running for 22 h 36 m so far!! :o
Can this be right? Or is this a zombie wu? ;-)
http://www.primegrid.com/workunit.php?wuid=339396977
Ja.. it has already been done of someone else.. and that took only an hour or so.
Please let me know if I should continue with this one...... or not.

That seems odd. I don't have time to look at it now, but I'll take a look later. A quick glance at all the processes shows them to all have the correct ending time. It's possible that some change we made makes it possible for a task to go from "invalid" to "valid", which could account for this behavior. I'm really not sure right now.

It's possible that some change we made makes it possible for a task to go from "invalid" to "valid", which could account for this behavior. I'm really not sure right now.
Ok, Jim and I (and by that I mean Jim) figured it out. This is a feature, not a bug.
There have been reports of an intermittent bug in the latest boinc client, 7.0.64, where immediately after uploading the result file to the server, something goes wrong in the client and the client then reports failure to the server instead of reporting success. As a result, the perfectly valid result is discarded.
We've noticed this behavior here at PrimeGrid, where there's valid result files uploaded to our server, but the client reports an error.
So, we (again, I mean Jim) wrote something to scan for these 'orphaned' result files, and change the result from invalid to valid, so it can then go through the validator and get credit.
So, there IS a mechanism where a result can transition from invalid to valid. On a standard boinc server that isn't possible, but it can happen here so we can keep people from losing perfectly good tasks because of this boinc bug.
So, that's likely what happened in this case -- the process that does this must have run between 18:00 and 18:15, and fixed a bunch of tasks that were in that faulty orphaned state. That resulted in the scores going upwards by a small amount.

My previous explanation is correct -- but it actually doesn't explain two significant facts. It is one of the reasons this can happen, but not the only reason:
* This doesn't explain why this behavior has been seen in past challenges.
* That process runs at 21 minutes past the hour, so it would account for the numbers going up between the 18:15 and 18:30 stats, but not between 18:00 and 18:15.
I may or may not dig into exactly what state transition is causing this, but there's something we put in there at some point that's "fixing" invalid tasks. We have a completely different validator than the standard boinc validator, and it's very thorough about trying to validate everything that can be validated. You could say that our goal is "No credit left behind."

Could you show the surrounding lines from the log? It's hard to tell what's going on just from that.
The image you showed shows 0% -- has it always been at 0%, or was it higher before and then dropped to 0?

I am betting very accurate. That is the number ready to be sent, the rest are currently being crunched. Since this is a new project a lot more people stayed on it after the challenge to badge up. Currently it showed none available, so it's currently only sending out either new or outside challenge rework.

I kept saying, over and over, that there's always enough people to do the cleanup work and there's usually very few tasks waiting to go out.
So I changed the display to show the exact number of cleanup tasks waiting to be sent, and... STILL nobody believes it! :)
Yes, within 24 hours of the end of the challenge, every cleanup task had been sent out. There will be more as some tasks expire or have errors, but the numbers will mostly be small from now on. As I write this, there's actually zero cleanup tasks available for both the SR5 and Woodall challenges.

That display says only 2 cleanup tasks are available. Is that accurate?
I kept saying, over and over, that there's always enough people to do the cleanup work and there's usually very few tasks waiting to go out.
So I changed the display to show the exact number of cleanup tasks waiting to be sent, and... STILL nobody believes it! :)
Yes, within 24 hours of the end of the challenge, every cleanup task had been sent out. There will be more as some tasks expire or have errors, but the numbers will mostly be small from now on. As I write this, there's actually zero cleanup tasks available for both the SR5 and Woodall challenges.
I believe you, so there you have it, you're welcome.
Btw, this run was smooth and well managed.
I congratulate all, and salute the admins\mods. | |

I'm a bit of disappointed with my scores of the SR5 WU's
I completed about 200 WU during the challenge..
All of them completed without error (@ least not seen in the log)
51% received a credit
49% were marked as "invalid" with no credit
running Boinc 7.0.28 on this machine
What is this about, cannot figure it out ?!
Any Idea ?
greetings .. Parabol

What is the overclock you are running, and the processor type you used?

You can see on my profile..
it's not hidden...
i7/860 ..
It is my 'workhorse' and had rarely problems the last 24 months
running 24hrs/all year long
doing regularely cleaning for good breathing of all the components..
overclocking should not be an issue, as all WU completed successfully

Can still happen when the result is fully tested, despite initially appearing to complete successfully.
I ran my 3960x at 3.6Ghz (stock 3.3Ghz), and that was fine - no errors. If your CPU was a higher percentage overclock, worth keeping it in mind, the LLR's are very sensitive to overclocking. | |

You need to take a look at that computer -- something's wrong. It's returning incorrect residues. For example:
Wingman 1:
53546*5^1014768-1 is not prime. RES64: B4BEF39F247E9135. OLD64: DDF4E28988D3BC4A Time : 8460.471 sec.
Wingman 2:
53546*5^1014768-1 is not prime. RES64: B4BEF39F247E9135. OLD64: DDF4E28988D3BC4A Time : 15310.430 sec.
You:
53546*5^1014768-1 is not prime. RES64: BE9259D6CDB4D0EE. OLD64: 9B93115A76CA771E Time : 7507.664 sec.
Wingman 2's computers are AWS servers and are extremely reliable, in addition to matching Wingman 1's results.
Overclocking and/or overheating are the most likely culprits.
