To continue efforts to create complete list of small GFN primes up to b=2G, a "Search for Small Primes" project will be started January 21, 2021, 09:00 UTC on "Private GFN server".

Note this is not a PrimeGrid project. It's running on a separate server, server address is http://boincvm.proxyma.ru:30080/test4vm/ (also note the non-standard port). If you're a new user here, you must create your account on the site first, using invitation code PrimeGrid. Automatic registration from Boinc client most probably will not work.

Project description

The goal is to create full list of GFN primes as far as software limit and computation resources allows. Historically, each sequence is tested, depending on it's complexity, either up to b=400M (old software limit) either up to b=2G. Current testing status is:

GFN-1 - GFN-11 - tested manually up to b=2G by a group of PrimeGrid users;
GFN-12 - tested on Private GFN server up to b=2G during first phase of this project;
GFN-13, GFN-14 - tested on Private GFN server up to b=400M;
GFN-15 and above - currently tested on PrimeGrid.

In the second phase, we will test GFN-13 from b=400M to b=2G.

Primes found during this search will be relatively small and cannot be reported to any "top" list. We will find thousand of them. Although they'll be collected mostly for statistical purposes, these primes can be used as a starting points searching for "chains" or "twin" primes, which may lead to another interesting and reportable discoveries.

Technical details

The project is GPU only.

We'll use new generation of Yves Gallot' program, "Genefer 2.0". Designed exclusively to test small numbers (when each test takes just a few seconds), it can test many candidates at once, fully utilizing your GPU and requiring almost no CPU time. It also implements Gerbicz error checking to detect hardware errors in GPU calculations (unfortunately, fast double-checking is not possible yet).

Task size has been selected to be about 30 minutes on a 1660-class GPU. Since task runtime is proportional to log2(b), first tasks will be completed faster. They'll reach expected length around b=300M and continue to grow slowly until end of project.

During first phase, when it was first time for Genefer 2.0 to be used in Boinc environment and on many different hosts, all tasks were fully double-checked. During second phase, a special reduced doublechecking scheme will be used. It requires only 25% of extra work (i.e. 1 special DC task will be sent for 4 normal tasks). This method differs from standard Boinc approaches, validation scheme will be difficult and non-standard. On site, you'll see that each workunit have only one result pending validation, which eventually will became validated (or not), and this delay can be very big.

Known issues

** No graceful error handling **

This program does not tolerates even slightest of GPU errors. If case of any calculation error, program will immediately abort with "Gerbicz failed" message. There are no restarts. Check GPU temperatures, underclock the GPU.

** A problem with multi-GPU systems **

A bug in version 1.00 causes program to always use first GPU in the system. It'll be fixed soon.

Update 1.01 fixed some multi-GPU issues, but it'll work only if your cards are of same type (i.e. all NVidia or all ATI). A combo of NVidia+ATI will not work. Correct fix is more complex. Hopefully it'll be done later.
Update 1.02 should have combo issues fixed (currently untested)

** Note **

Please avoid running this project on hosts which can interrupt GPU calculations often, especially on slow GPUs. For example, on systems which are configured to run Boinc or GPU tasks "only when user is not active", and user interrupts too often. Currently implemented checkpoint system saves only index of last fully processed candidate, but not a current state of each test. Although each individual test can be short (for example, 2 seconds), there are up to 256 test running in parallel. If a program will be interrupted again within 256*2 seconds, no progress can be recorded.

Published results

A list of all b-values can be downloaded from my disk https://disk.yandex.ru/d/BRQzejmjqpvVQ
This directory contains many GFN-related files.To get list of primes for GFN-12, look for "GFN12_primes_b_2G.7z" file. This file contains list of b-values, one per line. A file "readme_GFN0x.txt" contains short summary about status of all small GFN projects.

Interesting chains and sequences (GFN-12)

All primes were tested for possible sequences (Progressions, Twin primes and Cunningham chains). Results are posted below. Only newly discovered terms are shown here, it's assumed that corresponding b^n+1 is a GFN prime. Unfortunately, sequences made from GFN-12 primes are too small for T5K now.

Twin entries are not proven primes, they're PRP due to their "+3" part, and their length is still too big to be proved by other methods.

Please avoid running this project on hosts which can interrupt GPU calculations often, especially on slow GPUs. For example, on systems which are configured to run Boinc or GPU tasks "only when user is not active", and user interrupts too often. Currently implemented checkpoint system saves only index of last fully processed candidate, but not a current state of each test. Although each individual test can be short (for example, 2 seconds), there are up to 256 test running in parallel. If a program will be interrupted again within 256*2 seconds, no progress can be recorded.


Hmm I've just noticed that there are 2048 tasks in total, in 8 batches which means 256 per batch, runtime on a GTX1650 is around 22 minutes.

On a Vega 8 iGPU, there are 32 batches in total, with 64 tests per btach, I think the app detects the GPU and adjusts the batch size? Runtime is around 5-6 hours.

In fact, I can see the stderr output in the project folder and see if I found a prime in these 2048 tests 😁

What are your times?

On a Vega 8 iGPU, there are 32 batches in total, with 64 tests per btach, I think the app detects the GPU and adjusts the batch size?


It does a benchmark in the beginning of test (takes about 40 seconds on my system) and selects fastest parameters for given GPU (not only batch size, there are few others).

Tasks sizes are too different now because candidates are too small. They'll stabilize around b=300M.

Hmm I've just noticed that there are 2048 tasks in total, in 8 batches which means 256 per batch, runtime on a GTX1650 is around 22 minutes.
On a Vega 8 iGPU, there are 32 batches in total, with 64 tests per btach, I think the app detects the GPU and adjusts the batch size? Runtime is around 5-6 hours.

The number of tests per batch depends on the maximum work-group size. On Nvidia CL_KERNEL_WORK_GROUP_SIZE=1024 => 256 batches and on AMD CL_KERNEL_WORK_GROUP_SIZE=256 => 64 batches.
It is too bad this parameter is so small on AMD. This is a limitation of the driver, not of hardware. If this parameter was 1024, AMD GPUs would be more efficient for computations.

Ahh I see. big oops for AMD then...

And @stream could we have a status page for this project like before? Would there be too many primes?

It's at usual place (GFN-12-13-14 statistic).

Individual primes will be not shown - we'll have tens of thousands of them.

What happens if you run more than one at a time on the GPU?

Tasks sizes are too different now because candidates are too small. They'll stabilize around b=300M.

Is that what was happening at the start? Mine seemed to be doing nothing, I got 12 seconds of CPU usage, very little GPU usage, then nothing for quite some time, then it got going at full GPU usage.

By the way, AVG is (presumably falsely!) detecting the program as a virus. It sent it off for checking at their end, so presumably once they ok it, it won't bother any AVG users. I just clicked ignore and it worked :-)

Ah. I missed this note the first time I read the post. That knocks out my two dual-1660 Ti machines.

You could always forbid the second GPU to run that project in the app config file. Then at least you can run one GPU per machine on it.

** A problem with multi-GPU systems **
A bug in version 1.00 causes program to always use first GPU in the system. It'll be fixed soon.

When is "soon" roughly? Sometime during the challenge, or after?

Soon is today.


Yes, it looks like the updated 1.01 app version you rolled out has fixed this issue on my multi-gpu machines. Thanks!

Update 1.01 fixed most critical multi-GPU issues, but it'll work only if your cards are of same type (i.e. all NVidia or all ATI). A combo of NVidia+ATI will not work. Correct fix is more complex. Hopefully it'll be done later.

Working ok here with two different ATIs in the same machine. (R9 280X and RX 560).

Also working if I double up the tasks per GPU, it makes them run at 100% instead of 85%.

Good luck getting Nvidia to work alongside ATI, that used to be impossible with any project.

Was totally fine on my Win7 machine with GTX 970 in Slot 1 and Radeon 7750 in Slot 2 on several projects, after I stopped running Einstein on the AMD only and my other projects on the Nvidia only.
Especially on PrimeGrid I could run GFN-something on the Nvidia and PPS-Sieve on the AMD. Or different GFNs on both. Or the same ones.
Took the 970 out some time ago, so atm I don't mix GPUs.

So you're saying you usually had to run different projects on each?

I've actually heard of people not being able to get Windows to work with 2 different makes of card, nevermind Boinc, but that was a long time ago, perhaps drivers are better now.

I've got more PCs than cards, so it's easy enough to keep them grouped by similar card.

I've got more PCs than cards, so it's easy enough to keep them grouped by similar card.

As I think AMD cards are a PITA on Linux, I put my 7750 into the Windows box that also had a 970.
I used this combo to be able to run Einstein full-time on the Radeon, thus preventing difficulties with the amount of threads used by GPUs.
Most of the time this worked flawlessly. If not, Einstein had forgotten my preferences, and I had to set them anew.
As Einstein would get more out of my Nvidias, I changed my settings at some point in time and let Einstein use Nvidia, but set its GPU work to 0.45 CPU use instead of 1.
Played with venues on several projects and had the 7750 get work from Moo, Collatz, MilkyWay, and sometimes PrimeGrid.
I never had issues with Boinc mistaking cards and having work run on the wrong one.

Not having a problem here, but I only have 3 cards on it. My 4th card has (I think) a RAM fault and will only run smaller programs.

Update 1.01 fixed most critical multi-GPU issues, but it'll work only if your cards are of same type (i.e. all NVidia or all ATI). A combo of NVidia+ATI will not work. Correct fix is more complex. Hopefully it'll be done later.

Good luck getting Nvidia to work alongside ATI, that used to be impossible with any project.

Was totally fine on my Win7 machine with GTX 970 in Slot 1 and Radeon 7750 in Slot 2 on several projects, after I stopped running Einstein on the AMD only and my other projects on the Nvidia only.
Especially on PrimeGrid I could run GFN-something on the Nvidia and PPS-Sieve on the AMD. Or different GFNs on both. Or the same ones.
Took the 970 out some time ago, so atm I don't mix GPUs.

So you're saying you usually had to run different projects on each?

I've actually heard of people not being able to get Windows to work with 2 different makes of card, nevermind Boinc, but that was a long time ago, perhaps drivers are better now.

I've got more PCs than cards, so it's easy enough to keep them grouped by similar card.

As I think AMD cards are a PITA on Linux, I put my 7750 into the Windows box that also had a 970.
I used this combo to be able to run Einstein full-time on the Radeon, thus preventing difficulties with the amount of threads used by GPUs.
Most of the time this worked flawlessly. If not, Einstein had forgotten my preferences, and I had to set them anew.
As Einstein would get more out of my Nvidias, I changed my settings at some point in time and let Einstein use Nvidia, but set its GPU work to 0.45 CPU use instead of 1.
Played with venues on several projects and had the 7750 get work from Moo, Collatz, MilkyWay, and sometimes PrimeGrid.
I never had issues with Boinc mistaking cards and having work run on the wrong one.

I set everything to use 0.01 CPUs, as in zero. Most of the time it can get enough CPU by squeezing in with the other tasks, certain combinations need tweaking, but I only do that when necessary, first I try running two tasks at once on the GPU, if that fails I change it to need a core free. I go by the GPU usage in MSI Afterburner (you can also use things like GPU-Z, something with a graph is nice).

The only problems I've had recently with Boinc on GPUs is:
1) If you run two or tasks per card, it doesn't realise they will take twice or more as long, and downloads too much work.
2) For a short while after I added a 2nd card (both AMD) to this windows machine, it swapped over what it called d0 and d1 a few times. Strangely it's now settled to have them in the same order as everything else (as in Windows, utilities, etc). Historically Boinc always listed them in reverse order which was confusing when trying to work out which was the fastest one.

Is it only my pc's not able to upload work? No problem getting new work and server status
seems ok, all is up and running, although browsing the site is slow.

We noticed some network problems in Europe today, may be your traffic comes through one of affected paths. Connectivity was restored within a hour. No problems from other locations.

A lot of users with heavy equipement, my guess db starting to fill up?

No. This project is just a toy comparing to GFN-13/14. Only 102657 workunits for whole project. A GFN-13, for example, had 100K workunits just for 1M of search space. I only need to monitor disk space, it generates 1 Gb of results every day.

I'm in the UK and had difficulty using the Primegrid forums yesterday and the Steam (for games) forum, but everything else was ok. They were both timing out when trying to post.

That doesn't sound like much, this desktop has a 4000GB disk....

gfn1x_small - to find these names, you have to look in the file "C:\ProgramData\BOINC\client_state.xml", find the section for this project, then look for names.

I use this to make it run 3 at once, otherwise the GPU isn't fully used:

<app_config> <app> <name>gfn1x_small</name> <gpu_versions> <gpu_usage>0.333</gpu_usage> <cpu_usage>0.01</cpu_usage> </gpu_versions> </app> </app_config>

The project is 70% complete. With current (modest) participation level, testing of GFN-12 will be finished in 20-25 days, around April 01-03.

After completion of GFN-12, project will be paused until GFN-13 sieving reaches optimal level for new testing limits and application speed, then restarted on GFN-13, range 400M-2G (no estimated date yet).

Where is this sieving taking place? Is it "PPS Sieve" in the main Primegrid? I want to help with the sieve.

Where is this sieving taking place? Is it "PPS Sieve" in the main Primegrid? I want to help with the sieve.

The sieving for this project is manual sieving with gfsieve by Yves Gallot http://yves.gallot.pagesperso-orange.fr/gfsieve/. Up to 25,000P is complete in various intervals so far, but optimal for the project is ~75,000P. If anyone would like to help sieving please let me know either here or through private message and we would be more than happy for the help. The sieve software is a Windows executable and you can expect somewhere around 500P/day on an RTX 2070, or about 200P/day on a GTX 1080ti. Turing or Ampere are substantially more efficient with this sieving than other hardware (Volta would probably be good too, but there are few of us with any of those GPUs) and I am personally not running any instances on Pascal or older.

I suspended the GFN-13 sieving to help push GFN-12 forward and will resume once GFN-12 is completed. To do the sieving myself would take ~6-8 weeks past that point.

Sorry, not sure where I should post this. The LLR2 testing subproject over at the private server shows a weird status, is this normal?

http://boincvm.proxyma.ru:30080/test4vm/user_profile/llr2_status.html

I'm currently seeing a lot of lines saying completed (highlighted in green), yet they have 0 in the "ready" and "in progress" columns as though no work was ever issued.

Also, can I tell from the task name on my computers which one I'm doing? For example "llr2_1225592_qqk9ud" or "llr2_1226200_qqke0i".

I'm currently seeing a lot of lines saying completed (highlighted in green), yet they have 0 in the "ready" and "in progress" columns as though no work was ever issued.

It's OK, these k's had only 1-3 tasks to test and all of them were tested very quickly (see "Composite" column).

Also, can I tell from the task name on my computers which one I'm doing? For example "llr2_1225592_qqk9ud" or "llr2_1226200_qqke0i".

Unfortunately not. LLR task name is just a combination of sequential number of test database ID and timestamp. Tested number for finished tasks can be seen in task detail on server. For in-progress task, you can either peek inside stderr.txt files in slot directories, either on LLR command line. To view command line on Windows, open task manager, on Windows 10 select "detailed" tab - you should see a classic simple list of processes like in previous Windows versions, then you should find a "Choose columns" option - depending on Windows version, it may be available either in top menu, either after right-click on column names in the table or table itself, and add "Command line" to list of shown fields.

Thanks, you just taught me something about Windows! That will probably come in handy for other Boinc projects too, or even something else. I can see way more details about even system services.

Yes, only on GPUs. And a refernce speed for GTX1650 (better than a RX560) is 165P/day.

Will it run on AMD?

If it does, I've got the nice older ones (the 280X ones) with fast double precision if it uses that. Amazing on Milkyway for example.

Much appreciated Peter! All of the sieving intervals are farmed out right now and it looks like it will be about 2-3 weeks before it is all complete. Stay tuned for the start of the project though; GFN-13 will be a much bigger project than GFN-12 and we will need all the help we can get to finish it in a good time :)

And we're almost done with GFN-12! All candidates has been converted to workunits, and only 2800 workunits left unsent. When they'll be sent, project will be temporary paused until we finish additional sieving for GFN-13, then restarted on GFN-13. Stay tuned!

We're ready to continue!

Second phase of this project, GFN-13 search, will be started Monday, 26 April, at 09:00 UTC

In the second phase, we will test GFN-13 from b=400M (a point where previous GFN-13 search stopped) up to b=2G.

Notable changes comparing to GFN-12 search:

- The Genefer application has been tuned specially for GFN-13, speed improved by few percents.
- Issues with GPU combos (NVIDIA+ATI) should be fixed (although it wasn't tested on real setups yet).
- Since Genefer 2.0 has built-in Gerbicz check protecting against GPU errors, and it was found to be working very well during GFN-12 search, new reduced double-checking scheme will be used. An overhead of this scheme will be only 25% (i.e. 1 extra task per 4 "normal" tasks).
- Validation will be done completely "behind the scenes" and not visible on-site. You will see that workunit has only one result which is "pending validation". Eventually it'll become validated (or not). It happens because few independent workunits must be returned before decision can be made. In some cases, it'll take a while, so be patient. I'll monitor the situation to be sure that nothing is stuck.
- GFN-13 tests are about 4 times slower then GFN-12 (at least on my own GPU). So task size was reduced 4 times (512 candidates instead of 2048), and overall execution time should not change much.
- Credit coefficient was adjusted using benchmarks on my own GPU, to match PG GFN-17 more closely. I.e. you should get as much credit per hour as if you were running GFN-17 MEGA on PG. Of course every GPU is different, and your results may vary from my setup. But I expect that you'll receive more credit per hour, comparing to GFN-12.
- Individual prime lists will be available. But I'll need few days to write new statistics pages, so they'll be not available immediately on first day.

The project is not expected to be very long, just two times longer then GFN-12 (4x increase in test time compensated by reduced double-checking, also search range starts from 400M).

Good luck!

Great data. Looks like there are 201078 primes, which is 2.15 standard deviations below Yves's prediction of 202047.

- Issues with GPU combos (NVIDIA+ATI) should be fixed (although it wasn't tested on real setups yet).

Occasionally, a task errors out on the AMD card (without any error message), but overall, I can confirm that it is working on my NVIDIA GTX 1070 Ti + AMD RX 590 combo.

With other projects (Einstein, Milkyway, Collatz), I've been running 2 or more tasks at once on the GPU to give extra throughput when waiting for CPU assistance. Should I be doing that on this project and on the main Primegrid?

This project utilizes GPU very well, running 2 tasks may give better throughput only on fastest GPUs (top 20xx or 30xx models). A generic rule is to check GPU usage in your real setup first (Windows: use freeware GPU-Z utility, Linux: nvidia-smi installed together with drivers). If GPU usage is above 95%, running 2 or more tasks will not give noticeable effect.

Yes that's what I normally do, if the percentage is 85% or less, I add another task. My fastest card is only an R9 280X, but I have slow (or otherwise busy) CPUs.

The reason I asked is because I was wondering if a similar thing happens with Prime on GPU as on CPU, overloading the cache, etc., and adding more tasks would result in less overall throughput.

Do you think there will be more GFN-13 consecutive primes in the new search range? If so, how many are expected?

Do you think there will be more GFN-13 consecutive primes in the new search range? If so, how many are expected?

There will be more; almost certainly :)

So far, for GFN-1 through GFN-12 we have the following number of consecutive primes:
n # of consecutive 1 2360491 2 3834306 3 693201 4 507484 5 123008 6 36581 7 5702 8 8266 9 2021 10 611 11 132 12 43

GFN-13 should be 10-ish following that trend, although I'm sure someone with more maths in their brain has a calculated estimate. Yves Gallot wrote an excellent paper on this subject on August 4, 2020 titled "Gaps between generalized Fermat prime numbers", although I am not capable of calculating the expected number of consecutive primes as the math is well beyond my understanding. Perhaps he has a link to the paper and someone could use it to determine the expected. I only have my hard copy handy.

Using Gaps between GFN (Bateman and Horn conjecture with f1(x) = x2n + 1 and f2(x) = (x + 2)2n + 1) and an estimated value for Wn(2), the expected numbers of consecutive primes are
π1(2) = 2359599
π2(2) = 3833483
π3(2) = 693732
π4(2) = 507363
π5(2) = 122912
π6(2) = 36572
π7(2) = 5682
π8(2) = 8156
π9(2) = 2073
π10(2) = 593
π11(2) = 120
π12(2) = 41.0
π13(2) = 10.3
π14(2) = 2.3

Cunningham chain of the first kind (p; 2p+1) (PRP)

2*90894850^4096+3
2*279872090^4096+3
2*1515334610^4096+3

Twin (p; p+2) (PRP)

1249625230^4096+3
1272384106^4096+3
1569303862^4096+3

Two last types are not proven primes, they're PRP due to their "+3" part, and their length is still too big to be proved by other methods.

Late comment:

For the twins there, I see no way to prove them prime. PRP is likely the only thing you can do.

But for the Cunningham chains of the first kind there, which are also called pairs of Sophie Germain prime and safe prime, since the larger one, the non-GFN, is of form 2p + 1, where p is a prime, we have a full factorization of the neighbor number, so a proof should be possible.

Explicitly, 2*b^4096 + 3 = 2*(b^4096 + 1) + 1, and the expression in parenthesis is a proven prime.

All three Cunningham Chains of the First Kind primes mentioned have been proven prime now using PFGW and the helper file as above :)

25% done!

25% of this search is an equivalent of 400M range. An original GFN-13 search, which was first project on GFN server, tested candidates up to 400M, and it took more then 3 years. Now we did same range in just a 46 days!- thanks to new software, deeper sieving and, of course, your astounding participation!

There are no new special prime sequences (chains or progressions) yet.

And another 7% in the last 7 days! At this rate we will be finished by the end of August. If enough people pile in, and we double this rate, we could finish GFN13 by the GFN17-Low challenge ;)

Either way; this is some amazing progress!
