Welcome to Pierre de Fermat's Birthday Challenge

The seventh Challenge of the 2017 Challenge series is a 3 day challenge to celebrate Pierre de Fermat's Birthday! The challenge is being offered on several Generalized Fermat Prime Search Projects. All the sub-mega-prime GFN projects are included; 15, 16 and 17-Low.

Pierre de Fermat, French mathematician who is often called the founder of the modern theory of numbers. Together with René Descartes, Fermat was one of the two leading mathematicians of the first half of the 17th century. Independently of Descartes, Fermat discovered the fundamental principle of analytic geometry. His methods for finding tangents to curves and their maximum and minimum points led him to be regarded as the inventor of the differential calculus. Through his correspondence with Blaise Pascal he was a co-founder of the theory of probability.

Start of this Challenge has been chosen as the middle of the period research has narrowed Fermat's birth down to:
http://www.maa.org/press/periodicals/convergence/when-was-pierre-de-fermat-born
"Additional research led Barner to conclude that Fermat was born between October 31 and December 6, 1607."

Fermat is best known as the originator of Fermat's Last Theorem, which consists of a deceptively simple-looking formula famously scrawled in a book's margin, where he claimed the proof was too large to fit. The theorem's fame grew because – despite the efforts of countless mathematicians – four centuries would pass before the publication of a successful proof in 1995 by Sir Andrew Wiles, a Royal Society Research Professor at Oxford.

Fermat also has a little theorem. Fermat's Little Theorem is used in something called Fermat's Primality Test. The test tells us whether a whole number is a probable prime. Whereas a prime number is strictly a number only divisible by one and itself, a probable prime has similar properties but may be easier to generate. These numbers are very important in cryptography and internet security.

These GFN-projects are part of the challenge:
GFN-15
GFN-16
GFN-17 LOW

These GFN-projects are NOT part of the challenge:
GFN-17 MEGA
GFN-18
GFN-19
GFN-20
GFN-21
GFN-22

To participate in the Challenge, please select only the (GFN-15), (GFN-16) or (GFN-17-Low) projects in your PrimeGrid preferences section. The challenge will begin 17th November 2017 12:00 UTC and end 20th November 2017 12:00 UTC.

Application Builds


    IMPORTANT: Overclocking -- including factory overclocking -- on Nvidia GPUs is very strongly discouraged. Even if your GPU can run other tasks without difficulty, it may be unable to run GFN tasks when overclocked.

    Supported platforms:
  • Windows: Nvidia GPU (OpenCL): 32 bit, AMD/ATI GPU (OpenCL): 32 bit, CPU: 64 bit, 32 bit
  • Linux: Nvidia GPU (OpenCL): 32 bit, 64 bit, AMD/ATI GPU (OpenCL): 32 bit, 64 bit, CPU: 64 bit, 32 bit
  • Mac: Nvidia GPU (OpenCL): 64 bit, AMD/ATI GPU (OpenCL): 64 bit, CPU: 64 bit, 32 bit


A Cautionary Reminder


    ATTENTION: The primality programs (both GPU and CPU) 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.

    It is strongly suggested that you run at least one Work Unit before the challenge to make sure your computer can handle it. Note that "Overclocking" includes GPUs that come overclocked from the factory, and lowering clock rates to the reference speeds is sometimes necessary. In the case of one particular GPU, the GTX 550 Ti, lowering the memory clock below the reference speed is often necessary.

    WU's are currently averaging 30 minutes, 2 and 8 hours on CPU respectively and 8, 9 and 17 minutes respectively on 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 OpenCL. 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 November 17th 12:00:00 UTC and received BEFORE November 20th 12:00:00 UTC will be considered for credit.

    In this challenge we will be using the same scoring algorithm as we use to determine BOINC credits.

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 curently sieving n=17, n=18 and n=21. Please see New automated manual sieving system for more information.

It's awfully quiet in here, considering this challenge starts in less than 24 hours!

Some performance guidelines for the challenge:


  • Both CPUs and GPUs may be used, but GPUs are MUCH faster.
  • It pays to leave one CPU core idle to service the GPU(s). This will allow the GPU to run faster. On a 4 core CPU, setting the BOINC "Use at most ###% of the CPUs" setting to 75% will leave one core free; with 8 cores (or 4 cores with hyperthreading) set it to 87.5%.
  • On GPUs, you'll get better credit per hour (and hence challenge score) running GFN-17-Low. Today's large GPUs can't be fully utilized on the smaller GFN-15 and GFN-16 tasks.
  • On CPUs, you'll get almost identical credit/hour on GFN-15, GFN-16, and GFN-17-low, so it doesn't matter which you run.
  • On CPUs, you will get better overall performance with hyperthreading turned ON. The tasks will take longer to run, but you'll be running twice as many simultaneously, and overall you'll complete more tasks with hyperthreading.
  • If you're more interested in primes than score, you're most likely to find primes on GFN-15 and least likely on GFN-17-LOW.
  • GFN-15 primes are too small to be reported to T5K.
  • Only GFN-15, GFN-16, and GFN-17-LOW count for the challenge. All of the larger GFN tasks do not count!


Good luck everyone!

In case anyone is interested, Jim has about 450K GFN-15 tasks loaded on the server, and there's about 4 million more that either Jim or I could load in minutes, if needed. I think the server has enough tasks for the entire challenge, but we'll be monitoring our progress and will load more if needed.

I have both GPUs on the challenge, switched from the GFN22 for the next few days.

Will keep my cpus working on tasks without a GPU setting, don't think they will make much difference here. :)

I'm throwing all my CPUs at it. All two of them.

I recently inherited a new to me system and did a little upgrading to it just in time for the challenge.
Xeon E3-1231 v3, 8GB DDR3-1600, Radeon 6450 1GB
CPU is almost as fast as my i7-4790, but not quite. And I upgraded the video from the 6450 to a GT1030. I am very impressed with the 1030 so far. It is half the performance of my GTX1050ti in GFN17low for less than half the price and less than half the electricity consumption. I'd actually be better off with two 1030's than a single 1050ti.

Can I say that a challenge is a concentrated effort of distributed computing ? :)

Question: I plan to run the GFN 17 Low on my CPUs and GPUs, is that point effective? Mainly low power GPUs, 960s, 1050Tis, 750Tis and one Titan Black. The processors are mostly the "K" Haswell variety.

I have verified what Michael stated here:



  • On CPUs, you'll get almost identical credit/hour on GFN-15, GFN-16, and GFN-17-low, so it doesn't matter which you run.




On my GPU (GTX 1060 3GB), I get better credit/hour when crunching GFN17 Low WU's (when compared to GFN15 and GFN16).
I guess this is also true for other GPUs, but can't assure it.

Yes on the GPUs. GFN-17-Low is your best choice.

On the CPU it doesn't matter and you can run whichever of those three you want. If the CPUs have hyperthreading, you're probably better off turning it on for this challenge.

I recommend leaving one CPU core free to feed the GPU(s).

On my system (i5-4760K and GTX 1060 6GB) I plan on running GFN-17-Low on the GPU and 3x GFN-15 tasks on the CPU. On the CPU, my thinking is I'd rather be running shorter tasks, and I'm more likely to find a prime on smaller numbers. But in terms of points, the three GFNs by design produce very similar amounts of credit.

In theory, the same should be true for GPUs too, but today's GPUs are just too large to run efficiently on the small tasks. This makes them relatively more productive on the larger GFN-17-Low tasks.

I'm going to try this same setup, makes sense and will most likely have a few extra points at the end of the challenge due to not having as many outstanding units still crunching away. Noticed it takes five or so hours on my CPUs for GFN 17s.

I found something odd while doing some testing.
GTX1080Ti running 1 task at a time is just a little lesst than half the time of running 2.
Not much but few seconds one a 2 minute task adds up.

Here is the odd thing I found, running 2 or 3 tasks at once to load up the GPU, the CPU time the GPU uses is cut way way down.
At least it says so when I look at the task page where it gives time, CPU time and points awarded.

123 seconds CPU time per GPU task, down to 7 to 14 seconds of CPU time running 2 at once.
I would think the CPU time would go up as well as the GPU time doubles

I would think the CPU time would go up as well as the GPU time doubles

GPU tasks are a different animal. A critical resource is the bandwidth of the PCIE bus. My theory is there's not much for the CPU to do while the bus is busy doing data transfers, so it can do something else. But when when the bus is not busy transferring data, the CPU continuously checks whether the GPU task needs to be serviced. Does this make sense?

The first GFN-15 prime of the challenge has been found!

On a CPU. :)

(We're still technically waiting on verification and the wingman, but we don't expect GFN PRPs to be false.)

False Start!

I prepared all my GPUs for a “flying stard” while I am asleep. Unfortunately I forgot do click on the “No New Tasks” button for my main project on my Linux cruncher, so it downloaded a new tasks from another project as it got available…

Another observation on the computer I work with two GTX 970 http://www.primegrid.com/results.php?hostid=489627&offset=0&show_names=0&state=0&appid=24, it seems that the Gnefer17Low tasks get stuck on the first VideoCard: The Speed of the ventilator goes down – yes I can hear it – I see that the GPU load tends to be near 0 o 0 with EVGA OC Scanner, and in BoincView I am able to see that the progress % stops.

However, If I am controlling the GPUs times to finish the WUs on the PRIMEGRID Homepage, I am unable to find WUs with extended run times (double or triple the time) on this computer.

Any suggestions what is fooling me? And what can be done?

I have the same issue with a GTX 970 and Gener 17 Low WUs... they work fine for a few minutes, then all progress halts and I have to abort them. I've even under-clocked the card hoping for more stability, but that doesn't seem to help. (Card is not OC'd in the first place.. just stock.)

Do you have this problem only with GFN17Low, or also with GFN16 or GFN15?

Do not abort GFN17Low, it seems to me that they do just finish fine and in time. I do not know why?

This sounds like it's thinking there's issues during the processing and it's "pausing" to let the heat or whatever reduce. Did you ever wait for about 10 minutes to see if they started back up? I know you said you didn't OC the gpu but running both cpu and gpu will generate a ton of heat in the box. I know because it did on mine as well.

Just a thought as this might not even be the issue.

pci-e@1X gen.2 (load ~80% by GPU-Z ) can it be a bottle neck?

If I read your post correctly, you have 2 gpu's running in the same box? So it's possible one of the cards is creating enough heat to affect the other or both. Have you tried using just one of the cards? And make sure they have lots of good air flow or you might even have a cooler.

I know it's frustrating but GFN is very picky and always has been. Shorter tasks like gfn16 might run.

The only other thought is to downclock much lower and see.

Expanding on what Rick says, if there is no physical gap between the cards move one to another slot so there is space between them.

You'll probably get better answers to your questions if you unhide your computers.

I had a system go idle for periods, so wonder if that was happening in my case also. I'll never find the affected unit again to check if that was the case. What fixed it in my case was simply restarting the computer. I don't think it happened again after that.

Strange!

This computer does works within the Temp Limits: Te first GPU gets about 73º C hot and the second ab out 63º C hot, as I use a Fan Curve.

GPUGRID, which is more demanding never stoped/crashed becuase of temperatures.

As well, I do PPS Sieve and manual GFN Sieving on the same computer and never had issues.

I changed to GFN16, but I am still wondering what actually happens.

Change: I will do what mackarel suggested and try again.

Try rebooting the computer.

That kind of error (maxerr exceeded) is more commonly associated with only the OCL transform. When it happens on the other transforms, I believe it's indicative of a totally different root cause. Rebooting might clear up the problem if we're lucky.

Did restart! Did not help!

I switched to GFN16 and applied my old config file to run two WUs per GPU, although it does not change GPU load and I am not sure, if total turn-around is faster, than with 1 Wu per GPU.

Are you aware that only work units which were sent out since mid day today can score points for the challenge? Anything received before then will not count for the challenge even if it is returned after midday.
I suspect this may be why you currently have no points and therefore do not appear yet.
Suggest that you abort all work units received too early if you want to score challenge points.

Just a thought as this might not even be the issue.

It is the issue:
maxErr exceeded for 9683006^131072+1, 1.0000 > 0.4500
Errors occurred for all available transform implementations
Waiting 10 minutes before attempting to continue from last checkpoint...

See
http://www.primegrid.com/result.php?resultid=855322040


Doesn't appear to be heat related in my case. I increased fan profile, opened the window to winter air, and let the GTX 970 run at default 1404MHz. After temps dropped by over 15c from where I typically run it (and last had it hang), it hung again... on a Genefer 16 WU.

It does appear to be GPU frequency related, however. I had it running stable for the last few hours at about 1306MHz. I'll go back to that after this 10 minute wait expires.

Incidentally, the 2nd card in my box is a GTX 960, which runs at 1442 MHz (stock) and it never hangs.

So I guess this is to be blamed on Factory OC (or "Boost") feature of this EVGA 970 running a bit too fast.

Thanks for the help.

Win10 tried to sabotage my efforts by silently replacing my Nvidia driver, and after this BOINC stopped seeing my card completely. What is interesting, "GPU Caps" still was able to display OpenCL info about my card. Fortunately after updating driver to newest one from Nvidia things started working properly again.

You have not yet completed any tasks that are eligible for the challenge.

To be eligible for the challenge, tasks must satisfy ALL of the following criteria:

1) Be in one of the three challenge projects (GFN-15, GFN-16, and GFN-17-Low).

2) Be sent to your computer no earlier than the start of the challenge (12:00:00 UTC today).

3) Be received back at the server no later than the end of the challenge (12:00:00 UTC Monday).

#2 is where you have a problem.

All of the tasks you've completed were sent to your computer before the beginning of the challenge and are therefore ineligible for the challenge. That's why you don't show up on the leaderboard. While you do have tasks that were sent to you after the challenge began, and are elligible for the challenge, none of those have yet to be returned to the server.

Thank you
I've aborted all the work units sent before the challenge. Not a problem I will stay longer anyway I'm doing hours for wuprop on genefer 15.

Please check again. You still have many, if not hundreds, of work units downloaded up to 24 hours before the start of the Challenge. Look at your list of downloaded work units. If those units in the 'Sent' column is earlier than Nov 17 12:00:00, they won't count towards the Challenge results.

This is turning into a very interesting challenge!

A tremendous number of GFN-15 tasks are being crunched. Most of them are being crunched on CPUs. Over 100 thousand GFN-15 tasks have been returned so far, putting us on a pace to exceed 600 thousand GFN-15 tasks for the entire challenge.

Because of the nature of the application, on GFN-15 all those fancy-schmancy modern instructions that make LLR so fast are useless on these small GFN tasks. Because of that, modern Intel CPUs don't have the huge advantage they normally enjoy, and older CPUs and AMD CPUs are able to participate on a somewhat level playing field. That may be one reason for what looks to be unusually high participation.

Most of the GPUs, I expect, are on 17-Low. Wile only a third as many 17-Low tasks have been sent out, they represent about 5 times as many points or credit as the GFN-15 tasks.

Can you tell me why I don't appear in the stats of the challenge please?


You have not yet completed any tasks that are eligible for the challenge.

To be eligible for the challenge, tasks must satisfy ALL of the following criteria:

1) Be in one of the three challenge projects (GFN-15, GFN-16, and GFN-17-Low).

2) Be sent to your computer no earlier than the start of the challenge (12:00:00 UTC today).

3) Be received back at the server no later than the end of the challenge (12:00:00 UTC Monday).

#2 is where you have a problem.

All of the tasks you've completed were sent to your computer before the beginning of the challenge and are therefore ineligible for the challenge. That's why you don't show up on the leaderboard. While you do have tasks that were sent to you after the challenge began, and are elligible for the challenge, none of those have yet to be returned to the server.

Thank you
I've aborted all the work units sent before the challenge. Not a problem I will stay longer anyway I'm doing hours for wuprop on genefer 15.


It seems there's another advantage to having aborted all those older tasks and started working on the ones that are eligible for the challenge.

You found a prime on one of those tasks!

Congratulations!

(It's still being verified, so the official notification will come a little bit later.)

Or do wu's get credit only when them finish pending?

Credit for the challenge itself is after you return it, if started during the challenge. If the unit turns out wrong, that credit is reversed at at that time.

To clarify what Mr. PB said, that's how challenge points work. This way you get almost instantaneous updating of the leader boards.

Actual credit (normal credit, not the points for the challenge), isn't awarded until the wingman verifies your results.

All I can say, is "wow". Participation has been extraordinary. My pre-challenge estimate for GFN-15 -- assuming it was the only project in the challenge -- was that we'd need 300 thousand tasks for the challenge. We did more than that in the first day, and it's one of only three projects in the challenge.

Another metric I'm looking at is the team competition. Aggie the Pew has won every challenge this year. Right now, they're in fourth place. Looking at the teams in the first three positions, all are running way, way above their RAC. Simply put, everybody is really bringing it!

And, finally, the number of GFN primes being found is astonishing. I do a lot of manual bookkeeping on the GFN primes, and not only have I been very busy over the last 24 hours, but the server hasn't been able to keep up with the primality tests on all those primes! (I need to adjust some configurations so it can primality test more primes at once.)

In case you're wondering, as of right now, the first day of the challenge has produced 29 primes.

Great work everyone!

Interesting statistics.
Can we find 100 primes for 3 days?
I will run GFN 15 on GPU.
How long it takes to prove primality of GFN 15?
Do you use N+1 method?

The server, which doesn't use AVX or FMA3, takes about 45 minutes to primality test a GFN-15. We use LLR to test the numbers for primality. It uses the N-1 test. Here's an example of me manually running the LLR primality test on the recent GFN-18:

Might just be me but something in these gpu tasks are making my video drivers crash. it has happened on 3 machines. 2 of the machines have successfully crunched gfn17 mega thru gfn 21/22 fine for weeks. Just letting you know. just to add this has been only my Nvidia machines and only ones with 10 series cards. (1080, 1070 and a 1060) No oc at all and most are water cooled. I updated all drivers and will report further if I have issues.

Try 387.92, not the latest ones available. (None of the 388 drivers.)

I looked at the task lists of all of your active machines, and noticed something interesting.

Go down your hosts list, one by one, and click on the "tasks" list of every machine that is NOT running Windows 10.

You won't find a single error.

And on the machines that do have errors (all of them Windows 10), it's not every task that has an error. Only some.

If you look at the errors themselves, most of them seem to be some variety of "driver not found" or "no GPU device found".

Add it all up, and it sounds like these errors happened because the task was started while Windows 10 was doing an automatic driver update. Also, because it only takes a second or two for a task to fail like that, when the driver is in fact updated, a whole bunch of tasks will fail because of it.

It sounds like there's nothing much to worry about here, except, of course, for the possibility of Win 10 updating the driver when you're 99% done on a long GPU task.

Windows 10 updates have been very annoying the last couple of days (lousy timing). I have had multiple systems where updates started, broke the graphics driver, and then didn't complete, resulting in lots of error tasks. These systems ended up with blank screens (maybe a mouse pointer). This persisted after an ACPI shutdown and reboot. A hard power cycle brought them back, updates completed, and the drivers were working.

I'm now checking constantly for problem systems.

Strange!

This computer does works within the Temp Limits: Te first GPU gets about 73º C hot and the second ab out 63º C hot, as I use a Fan Curve.

GPUGRID, which is more demanding never stoped/crashed becuase of temperatures.

As well, I do PPS Sieve and manual GFN Sieving on the same computer and never had issues.

I changed to GFN16, but I am still wondering what actually happens.

Change: I will do what mackarel suggested and try again.


I just had this happen to the GTX 960 on my son's computer. It's not a computer I've ever used for crunching before, so I don't have any history about it's reliability, and I don't have temperature monitoring software installed. That being said, it sounded like the GPU fan was getting a nice workout. :)

It's hard to say what caused it -- basically it could be a lot of things. I need to see if this happens a lot or not. It's been running GFN-17s for almost a day and a half now before this one task broke.

You can see in this weekly graph of GFN Tasks in progress, GFN-15, GFN-16 and GFN-17-Low Tasks slowly built up and then took off at the challenge start. They've levelled off now:

The individual battle for first place is very, very close, as is the team battle for third place. Due to the nature of this particular challenge, modern CPUs don't have the advantage they normally do, so both old and AMD CPUs can compete on a relatively level playing ground. It looks like people have been putting everything they've got into this challenge!

We would prefer users "moving on" to finish those tasks they have downloaded, if not then please ABORT the WU's (and then UPDATE the PrimeGrid project) 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. Thank you!

Might just be me but something in these gpu tasks are making my video drivers crash. it has happened on 3 machines. 2 of the machines have successfully crunched gfn17 mega thru gfn 21/22 fine for weeks. Just letting you know. just to add this has been only my Nvidia machines and only ones with 10 series cards. (1080, 1070 and a 1060) No oc at all and most are water cooled. I updated all drivers and will report further if I have issues.


I looked at the task lists of all of your active machines, and noticed something interesting.

Go down your hosts list, one by one, and click on the "tasks" list of every machine that is NOT running Windows 10.

You won't find a single error.

And on the machines that do have errors (all of them Windows 10), it's not every task that has an error. Only some.

If you look at the errors themselves, most of them seem to be some variety of "driver not found" or "no GPU device found".

Add it all up, and it sounds like these errors happened because the task was started while Windows 10 was doing an automatic driver update. Also, because it only takes a second or two for a task to fail like that, when the driver is in fact updated, a whole bunch of tasks will fail because of it.

It sounds like there's nothing much to worry about here, except, of course, for the possibility of Win 10 updating the driver when you're 99% done on a long GPU task.



I am not saying it is a not win10 issues because lord knows I have had many troubles with that OS, but I have driver updates turned off on all of my machines.

FYI

How do I stop Windows 10 from updating my graphics driver?

Right click the Start button and select Control Panel.
Click System.
Click Advanced system settings from the left sidebar.
Select the Hardware tab.
Press the Device Installation Settings button.
Choose No, and then press the Save Changes button.

I just turn off update services in the desktop services app.
Then I turn it back on once a month and run update on a Wednesday.

Strange!

This computer does works within the Temp Limits: Te first GPU gets about 73º C hot and the second ab out 63º C hot, as I use a Fan Curve.

GPUGRID, which is more demanding never stoped/crashed becuase of temperatures.

As well, I do PPS Sieve and manual GFN Sieving on the same computer and never had issues.

I changed to GFN16, but I am still wondering what actually happens.

Change: I will do what mackarel suggested and try again.


I just had this happen to the GTX 960 on my son's computer. It's not a computer I've ever used for crunching before, so I don't have any history about it's reliability, and I don't have temperature monitoring software installed. That being said, it sounded like the GPU fan was getting a nice workout. :)

It's hard to say what caused it -- basically it could be a lot of things. I need to see if this happens a lot or not. It's been running GFN-17s for almost a day and a half now before this one task broke.

The recommendation from Shaun worked. I down-clocked the two GTX 970 cards by 62 Hz, and the problem disappeared.

Now the cleanup begins. I expect it to take 2 to 3 weeks. Feel free to help with the cleanup if you wish, but it's not mandatory and the cleanup tasks will get sent out fairly quickly just with normal usage.


Cleanup Status:

Nov-20: Pierre de Fermat's Birthday: 119146 tasks outstanding; 106517 affecting individual (288) scoring positions; 43682 affecting team (54) scoring positions.

How many primes did we get out of this surge?


Well, you see, the challenge statistics and cleanup statistics are produced by the server. That's why I published them first. The primes need to be recorded by hand before they can be counted, and that takes a little while. So here's the final prime counts for the challenge, which include an n=16 and an n=17 that haven't been reported yet and thus aren't visible right now.

GFN-15: 61 primes
GFN-16: 6 primes
GFN-17-Low: 6 primes

Congratulations to everyone who found a prime!

Thanks for those. I was one of those 61 GFN-15 primes.

Since it seems like we had more people (or at least more throughput than was expected) I'm curious as to what the participation percentage is.

That's really hard to say. Even if the necessary data for that was readily available (it's not), determining what is a "challenge participant" would be rather subjective. Someone who didin't crunch at PG for a week? A month? Three months? A year?

I did a quick check for participants with recently created accounts. Only 8 created their account after the challenge began. 5 more in the day before the challenge. 53 total since the beginning of November. None did a tremendous amount of work. A few have been active on the forums or the chat room, and I'm pretty sure they didn't join for the challenge.

What's clear is that a lot more computing power was online than usual. Some of it was came from our other sub projects, but most did not. People either moved computers from other projects to PrimeGrid, or turned on computers that weren't usually crunching, or payed for some cloud servers for that extra push. And I'm sure some people came here just for the challenge. I suspect many of those are members of the teams at the top of the leader board since those teams organize their challenges.

But I don't have hard numbers.

I may have misunderstood the question. :)

I was trying to answer, "How many challenge participants were here ONLY for the challenge."

Mike if you know ( I dont need exact number, just approximate) how many candidates is process between two primes

10368632^131072 + 1
10037266^131072 + 1

Thanks

You've got them listed in reverse order - they're really not very close. There are 44618 candidates between those two primes, not including the primes.

What's clear is that a lot more computing power was online than usual. Some of it was came from our other sub projects, but most did not. People either moved computers from other projects to PrimeGrid, or turned on computers that weren't usually crunching, or payed for some cloud servers for that extra push. And I'm sure some people came here just for the challenge. I suspect many of those are members of the teams at the top of the leader board since those teams organize their challenges.

But I don't have hard numbers.

=> 9.29% Active user participation in the Challenge.

Thanks - I guess I should have realized the datum is readily available for the current challenge (I blame lack of caffeine). Also surprised that it's that low of a percentage.

I was trying to answer, "How many challenge participants were here ONLY for the challenge."

Because of the way I worded my question, that fits (and is just as interesting). I would use didn't crunch for a Month since BOINC considers "granted credit within the last 30 days" as "Active".
So how much did the active user count spike in the days leading up to the challenge?
I found some neat graphs on BOINC Stats that answer that: https://boincstats.com/en/stats/11/project/detail/user

I have been here awhile but it was the first challenge I actively participated in, as in consciously crunched the correct projects. ;)

I had what I think was a pretty good challenge. 2 gfn16 and 1 gfn15 primes. Can't wait for the next one :D

Mike if you know ( I dont need exact number, just approximate) how many candidates is process between two primes

10368632^131072 + 1
10037266^131072 + 1

Thanks

You've got them listed in reverse order - they're really not very close. There are 44618 candidates between those two primes, not including the primes.


So one GPU like my 750 Ti ( 21 minutes per candidate), will process them in 650 days :)

Here are some bases that were "hits" in GFN131072-low:

9,785,844 9,907,326 10,037,266 10,368,632 10,453,790


You see that the "distance" you ask about is relatively long.

Now the cleanup begins. I expect it to take 2 to 3 weeks. Feel free to help with the cleanup if you wish, but it's not mandatory and the cleanup tasks will get sent out fairly quickly just with normal usage.


Cleanup Status:

I left all of my 750ti's on this to help :) All the tasks are cluttering up my pending credit page LOL

LOL! That is great! I love that our grid computing capacity is still weather-dependent.

One of my teammates left a window open overnight to take advantage of nature's cooling system. Another could not and suffered through 30°C house temps.

As of right now, there's almost no cleanup tasks waiting to be sent out. This is typical; most of the cleanup is waiting for tasks to be processed and returned. There's very little time spent waiting for the tasks to be sent out. Please feel free to assign your equipment to whatever you prefer to process.

There will be more cleanup tasks available as people abort challenge tasks they're not going to complete, and in about 2 days we'll also start seeing tasks that have timed out. But it's impossible to predict exactly when those will become available and how many there will be.

I just realized something, looking at the numbers for the challenge.

For GFN15 (n=32768), about 10% of all the work ever done, anywhere, was done in the last 3 days during the challenge.

For GFN 17 (n=131072), excluding the mega part of the search above b=42M, about 12% of all the work ever done was done during this challenge.

Not so sure. I found it great fun. Exciting. And kept me entertained for three whole days checking in. And cost relatively little. Anyway I bow to your experience 😊 cheers

Some things in life are amazing, but only in limited quantities. Primegrid challenges are like that. Can't have too few or people stop paying attention, and can't have too many or people will start skipping them and then stop paying attention.
Gotta find that balance to keep them always on the mind, but not so frequent that they lose their luster.

Since it seems like we had more people (or at least more throughput than was expected) I'm curious as to what the participation percentage is.
Active users vs Challenge participants; overall vs this challenge.


For me personally, Numberphile's YouTube video about Proth Primes (https://www.youtube.com/watch?v=fcVjitaM3LY) renewed my interest in PrimeGrid, and this challenge just happened to be timed well with with that. Very fun way to get back into it!

Agreed.
Overlapping with different other challenges (non-PG, other BOINC projects) is also viewed in negative light.

Based on primes found, GFN15 was B ~66M before start of latest challenge.
Recent primes are in B ~75M region.
B limit for OCL2 is ~95M, x87 limit is ~99M.
Two more succesful 3-days challenges and we will hit B limits both for CPU and GPU, which is game over for GFN15, assuming the same software used.
And there should be a bit of progress in the meantime as well.
So a week of similar challenge will put an end to GFN15.
Just saying, not complaining...but correct me, if I'm wrong.

On a longer term, with both GFN17 at similar throughput: GFN17mega will hit B limit sooner (now at 47M6, limit OCL2 ~60M) before GFN17low will join it (now at ~10M8, GFN17Mega started at 42M6, but considerably later).

More on subject of when we will reach b limit, see Mike's post from June.
Mike, it might we worth updating your estimates. Low priority I guess.

B limit for OCL2 is ~95M, x87 limit is ~99M.

B limit for OCL2 is 400M for any n.

x87 limits are about

You're talking about the old OCL2 transform, which isn't used anymore. What you see as "OCL2" is actually the old "OCL4 3 prime" / "OCL4-High" transform, which has a B limit of 400,000,000 for any n.
