Welcome to PrimeGrid's Generalized Fermat Prime Search

The numbers F(b,n) = b^2^n+1 (with n and b integers, b greater than one) are called generalized Fermat numbers. In the special case where b=2, they are called Fermat numbers, named after Pierre de Fermat who first studied them.

This search is for primes of the form b^2^n+1. With David Underbakke's recent improvements to AthGfn64 and his development of Genefx64, the Generalized Fermat Prime Search has become very attractive.

A previous project already completed a substantial amount of work. The Generalized Fermat Prime Search was a premier project from 2001-2004 ranking second only to GIMPS in organization and size of primes found. We'll be doing some spot double checks as well as filling in the gaps that remain. Then we'll advance the limits already established.

As mentioned earlier, David Underbakke's AthGfn64 sieve program will be used to sieve. His Genefx64 program will be used to PRP test the remaining candidates and PFGW will be used to primality test all PRP's found. Once the b limits of Genefx64 have been reached, we'll switch to Genefer, developed by Yves Gallot. After the b limits of Genefer have been reached, we'll use his Genefer80. Finally, when those b limits have been reached, we'll finish the rest of the range with PFGW.

The search range is as follows:

n = 2, 4, 8, 16 for b < 1,000,000,000
n = 32, 64, 128, 256, 512, 1024, 2048, 4096, 8192, 16384, 32768, 65536, 131072, 262144, 524288, 1048576, 2097152, 4194304, 8388608, 16777216 for n < 100,000,000

Much of the smaller n work has already been completed. The main search will start at n=32768 in PRPNet (prpnet.primegrid.com:12005). We'll test some gaps and then start testing above 3149688^32768+1.

As sieving progresses, 65536, 131072*, 262144, and 524288 will be added to PRPNet so users can have a selection of testing times from which to choose. NOTE: There's only been 1 prime found at n=262144 and none found at n=524288. Therefore, finds at those levels will be quite significant. Of course, they'll take some time to test as well. :)

*131072 is currently reserved.

Sieve depths as of 4 November are:

n = 32768; p=500P
n = 65536; p=500P
n = 131072; p=395P
n = 262144; p=530P
n = 524288; p=120P

Sieving will continue throughout the search. We hope to push all of these up to 1E within the next month or so.

A special thanks to David Underbakke for his AthGfn6v and Genefx64 and to Mark Rodenkirch for PRPNet. Also, thanks to them both for their collaboration in updating Genefx64, Genefer, and Genefer80 to prepare the programs for a distributed effort.

Whilst I understand that "We'll be doing some spot double checks as well as filling in the gaps that remain", it seems that the only n being tested at present is 15 (i.e. 2^15 = 32768) and on ranges previously covered.

When will we be moving to new test ranges?

Fair enough. It's not a criticism, merely my curiosity.

Essentially, I'm interested in what the plans are for the different n and what ranges will be double-checked before we get into virgin territory.

Whilst I understand that "We'll be doing some spot double checks as well as filling in the gaps that remain", it seems that the only n being tested at present is 15 (i.e. 2^15 = 32768) and on ranges previously covered.

When will we be moving to new test ranges?

We are exploring "gaps" in the primes posted at the Prime Pages to see if they are true gaps or caused by missed primes. A quick glance shows these as possible "gaps" for n=32768:

553602<b<743788 (currently testing)
855124<b<999236
1277444<b<1519380
1519380<b<1755378
1755378<b<1909372
2034902<b<2147196
2167350<b<2279250
2696506<b<2973894
3000336<b<3109540
3149688<b<10021136
10021136<b<100M

While most of these ranges are shown as complete by the previous project, we suspect there might be a few primes in there. The only way to know for sure is to double check their entire work...which is not our intention at this time.

We started at 32768 because that's the lowest n that will qualify for the top 5000 primes and the tests themselves are relatively quick.

As sieving advances on the other n, we'll insert those into PRPNet as well. As n increases, the "gaps" are fewer so we'll enter untested territory sooner.

A prime find at n=262144 or 524288 will be quite significant! :)

Whoops, what a silly question! We're doing it over at the same place as PPSE Sieve! Oh well, at least I realised the error while out cycling.

Heh yeah I find going for a drive clears my thoughts if I'm stuck on a problem or project that I can't solve, it normally comes to me in the drive :) On another note, I see GFN is getting more people to join since I've been doing WU's as well thats awesome for the new project. Your crunching them as well right Warped?

On another note, I see GFN is getting more people to join since I've been doing WU's as well thats awesome for the new project. Your crunching them as well right Warped?


Yes John, I've been doing some at both port 12003 and port 12005. I'm back onto sieve work now though. I participated in the original project back in 2002 as well.

Good luck - there's plenty of these to crunch. :-)

I've been crunching a few if these again after being away for my annual holiday. I note that we have progressed to n=65536. However, I have noticed a number of instances where a particular core completes a task (say 673074^65536+1) only for another core to pick up that same task from scratch again. Is each number being crunched twice for validation purposes?

You had done that number and 32 more that had expired.

I have increased time now. Hope that will solve the problem.

Message 20270 - Posted: 4 Jan 2010 | 19:54:28 UTC - in response to Message 20269.

There are a couple of components here that could affect this.

First, expiration. The server has a hard time limit in which a work unit must be completed. This is based upon the number of decimal digits of that workunit. This is what happened in your case.

Second, double-checking. The server has a switch that enables double-checks. This double-check is used to ensure that two tests for the same number have the same result. If the results do not match, then one (or both) of the tests are invalid and another test has to be done until two tests have matching results. It is extremely unlikely (well under 1/2^64) for a test to have an error, for that error to be undetected by the software, for the test to complete, for the client to report a residue for the test (instead of reporting an error), and for that residue to match a residue from a valid test. The double-checking logic can be configured on the server side to ensure that a test is run on a different computer than other tests for that number. I presume that Lennart has the server configured to run double-checks on a different user/client combination. If not, it would be possible for you to get a double-check on the same computer that did the first test.

I presume that Lennart has the server configured to run double-checks on a different user/client combination. If not, it would be possible for you to get a double-check on the same computer that did the first test.

Since genefer.exe roundofferr, I stopped work on port 12005 which basiccaly ment no clients working on that port.
I assume there are only a few clients working on that port -> higher chance of doing double checks on the same user/client.
(looking at http://prpnet.primegrid.com:12005/pending_tests.html - there are no pending tests at the moment)

If you have genefer80, then the client will try to test with that version of genefer. If you have PFGW, phrot, or LLR configured, it will try with those. This was added in the 2.4.7 client.

GFN Update

It's been a long time coming but it's finally here. N=262144 and 524288 have now been added to PRPNet!!! Thanks to Honza for coordinating the sieve and to the many others who helped him sieve, we now have sieve depths at unprecedented levels. :) We will resume sieving at some point in the future but for now, it's time to see if we can find a prime. The sieves are at the following depths:


  • N=32768, suspended at 1001P
  • N=65536, suspended at 1500P
  • N=131072, suspended at 2000P
  • N=262144, suspended at 2510P
  • N=524288, suspended at 3070P


There has only been 1 prime found at N=262144 and none found at N=524288. Therefore, finds at these levels will be quite significant...and of course, their testing times will be quite long too. Primes are at Mega Prime level. We have yet to do any testing of N=524288.

To participate in any of the GFN searches, uncomment the following in the master_prpclient.ini file:

//server=GFN32768:0:1:prpnet.primegrid.com:12005
//server=GFN65536:0:1:prpnet.primegrid.com:12003
//server=GFN262144:0:1:prime2u.com:11002
//server=GFN524288:0:1:prime2u.com:11001

Note: N=131072 is reserved

Win64 users have the best advantage with these searches as they can utilize Genefx64 with is the fastest of the four programs (Genefer, Genefer80, and pfgw are the other three). While these searches are not limited to only Win64 users, testing times using the other programs are longer.

The upper bounds for each program are as follows:

Genefx64 Genefer Genefer80 pfgw The upper bound m = 32768, b = 1,510,000 : 2,085,000 : 63,660,000 : + The upper bound m = 65536, b = 1,240,000 : 1,695,000 : 50,980,000 : + The upper bound m = 131072, b = 1,025,000 : 1,365,000 : 41,850,000 : + The upper bound m = 262144, b = 865,000 : 1,170,000 : 34,790,000 : + The upper bound m = 524288, b = 735,000 : 975,000 : 28,820,000 : +


So as you can see, N=524288 can be tested up to b=735,000 using Genefx64 before switching over to Genefer to be tested up to b=975,000. Currently, only N=32768 can no longer utilize Genefx64 or Genefer as testing has already reached b=3,169,866.

Finally, the programs are only available as follows:

  • GenefX64 - Version 2.2.0 (Windows 64 bit only)
  • Genefer - Version 2.2.0 (Linux, Windows, MacIntel, MacPPC)
  • Genefer80 - Version 2.2.0 (Windows only)
  • pfgw - Version 3.3.4 (Linux, Windows, MacIntel)


Best of Luck in the search. Who's going to make history by finding the first N=524288 prime??? :)

What does this mean? Does this mean the PrimeGrid has it reserved or does someone else have it reserved?

Note: N=131072 is reserved


What does this mean? Does this mean the PrimeGrid has it reserved or does someone else have it reserved?


I'm guessing that Puzzle Peter is probably doing this range with all those "non-networked" boxes of his. :)

I picked up the first test for n=524288 for my Win64 machine and it came up with this:

[2010-06-10 03:14:39 GMT] Candidate: 4^524288+1 Program: genefX64.exe Residue: PRP Time: 0 seconds
[2010-06-10 03:34:06 GMT] PFGW could not prove primality for 4^524288+1. Time: 1167 seconds

I know little about these things but aren't composite PRP's rare among huge numbers such as this? So I'm really asking has my computer produced an erroneous result? It's a C2Q Q9550 at stock clock (2.83 GHz). I did interrupt the test once to change the PRPNet server configuration.

Also, in the above quote from test_results.log the genefX64 run time is missing. Should it be there? The program itself reported a run time of 5h 36min.

The time of 0 seconds is extremely suspicious. It seems that genefx64 might have had an error and that PRPNet was unable to detect it. Can you run it from the command line and post the output? We might need to get some assistance from David on this.

I've got work units that range from 40^524288+1 to 60^524288+1 running on a couple of Win64 machines (one Vista one Win7) and they have been crunching all morning so I'm looking at around 18 hrs to complete. Getting one of the first units might crunch in very little time IMO. It would seem that it would be easy to test that particular unit (except I'm not certain how to actually accomplish that part).

As I said, I interrupted the first run with ^C. It did say this

genefer shouldn't create that log file unless it will write to it. This is rather mysterious. Did it say where the checkpoint resumed from?

Sorry, I closed the window in which it had run and I can't remember exactly. The file genefer.ckpt was there and I do remember thinking it didn't appear to lose much time, if any.

It is important to run with the -r option. That is used to verify that it compiled correctly. If this number isn't prime, then there could be a bug with genefx64.

It is important to run with the -r option. That is used to verify that it compiled correctly. If this number isn't prime, then there could be a bug with genefx64.

It does say in readme_genefers.txt that genefer and genefx64 "can only
handle a limited range of lower b values." I'll run the number with genefer80 just to try and put this to bed (hopefully).

FYI...Lennart has run -r with genefx64, genefer, and genefer80 and all three match. Additionally, he ran pfgw without -t so that we could determine residue:

4^524288+1 is composite: RES64: [11BEF945BB1F0767] (1316.5260s+0.0078s)

Sadly, this is one of those instances in which a prp is proven composite. To be safe, we have also asked David to review this. Additionally, Lennart is running the test using genefer to see how it classifies the candidate.

Sadly, this is one of those instances in which a prp is proven composite. To be safe, we have also asked David to review this. Additionally, Lennart is running the test using genefer to see how it classifies the candidate.

Lennart's testing with all three genefers produced the same result. It appears that this is a known observation about the genefers. David provided this nice explanation:

The genefer implementation of the probable test is susceptible to worst case conditions where the b value (b^n+1) is a small power of 2. You will notice there is the same problem with many bases. The following all create a false positive:

2^256+1, 4^256+1, 16^256+1, 2^512+1, 4^512+1, 16^512+1, 2^1024+1, 4^1024+1, 16^1024+1, 2^2048+1, 4^2048+1, 16^2048+1, 2^4096+1, 4^4096+1, 16^4096+1,
2^8192+1, 4^8192+1, 16^8192+1, 2^16384+1, 4^16384+1, 16^16384+1, 2^32768+1, 4^32768+1, 16^32768+1

This behavior hasn't been seen before largely because all the small b values were tested before genefer was used. We can expect this special circumstance for small b's < 1024 that are powers of 2 (2,4,8,16,32,64,128,256, and 512). Other than that particular nuance, there's nothing else to be concerned about.

Using llr:

I have no idea if llr is the appropriate program, I just thought I would give it a try. Took a lot longer than I expected (~11.6 hours).

Lennart has already explained this to me via PM. PFGW automagically kicks in when PRP is found and in my case proved this number as composite.

Looks like we just have to dig through all these b's lower than 1024...

I don't see any harm in removing all candidates where b is a power of 2. These are Fermat numbers and the primality of all of them that this project will touch is already known.

Message 24359 - Posted: 16 Jun 2010 | 14:37:10 UTC - in response to Message 24356.

Actually, I believe only the b values that are powers of 2 and perfect squares are fermat numbers. That would be b= 2, 4, 16, 256, and 65536.


    2^262144+1 which is Fermat F18
    4^262144+1 = 2^524288+1 which is Fermat F19
    16^262144+1 = 4^524288+1 = 2^1048576+1 which is Fermat F20
    256^262144+1 = 16^524288+1 = 2^2097152+1 which is Fermat F21
    65536^262144+1 = 256^524288+1 = 2^4194304+1 which is F22
    65536^524288+1 = 2^8388608+1 which is F23


There are know factors for F18 through F23. In the case of the 256^524288+1, which was F22 I can give two factors, 64658705994591851009055774868504577 which is prime, and 3853959202444067657533632211*2^24+1, discovered very recently, by D. Bessell & Woltman on March 26, 2010.

I would remove only b values 2,4,16,256, and 65536.

Hi ,
I convert genefer.c to CUDA.
see http://mersenneforum.org/showthread.php?t=14297
Thank you,


It can't be used by PrimeGrid/PRPNet until it supports everything in genefer 2.2.0.

I've done considerable work on GFN sieving and primality test.
I would like to try GPU version for off-line running, starting small Ns (running CUDA/Win) which are not available on PRPNet.

You still need a way to verify that there were no errors during the test. In other words, you need to compare to known residues to know that the build is valid. Version 1.3 has no code to produce residues.

Yes, still have .log files for N=32...2048 (up to b=100M) and N=4096 up to b=11M7
11781472^4096+1 is a probable composite. (RES=3bae6312ebca69ea) (28964 digits) (err = 0.0057) (time = 0:00:24)
I've also done about 16k tests for N=262144, b<100k
99224^262144+1 is a probable composite. (RES=9772a7694d7df19f) (1309834 digits) (err = 0.0059) (time = 10:41:11)

I guess a good base for testing original CPU Genefer 220 vs CUDA version.

Checked Windows version (compiled by Ken using 2.3 SDK, perhaps slow for GTX 580).
Heavy CPU load for 8192, 16384 and 32768 then it come better.

I would like to try version compiled using 3.2 SDK if provided.

Ken has built Windows version of Shoichiro's CUDAGenefer. It can be downloaded here: CUDAGenefer-0.95 (Linux64 by Shoichiro). This one was updated to 0.95 and built with CUDA 3.2. :) If you need the cufft.dll, it can be downloaded here.

We hope to have a Linux version soon. EDIT: Now available for 64 bit.

For now, this can be tested on the following GFN ports:

//server=GFN65536:0:1:prpnet.primegrid.com:12003
//server=GFN262144:0:1:prime2u.com:11002
//server=GFN524288:0:1:prime2u.com:11001

GFN32768 has already reached the max b limit of CUDAgenefer. Do not attempt this port as the PRPNet client will switch to pfgw to test.

To run CUDAGenefer, just update the genefer section in the master_prpclient.ini file before updating all the clients.

    // This is the name of the genefer executables used for GFN searches. Up
    // to three different Genefer programs can be specified. The client will
    // attempt a test with genefx64 first. If a round off error occurs, it will
    // try genefer. If a round of occurs in genefer, it will try genefer80. If
    // genefer80 fails, then the number cannot be tested. The order they are
    // specified here is not important.
    Win32 & 64 users should have the following:
    geneferexe=CUDAGenefer.exe
    geneferexe=genefer.exe
    geneferexe=genefer80.exe

    Linux64 users should have the following:
    geneferexe=./CUDAGenefer
    geneferexe=./genefer

    MacIntel32 users should have the following:
    geneferexe=./CUDAGeneferMacIntel32
    geneferexe=./genefer

    MacIntel64 users should have the following:
    geneferexe=./CUDAGeneferMacIntel64
    geneferexe=./genefer


For Win64 users, GenefX64 will not run while using CUDAGenefer. Mark is working on a solution for the next PRPNet release which will allow GenefX64 to be included again.

p.s. If all goes well, CUDAGenefer will be added to the official packages (well, to Linux and Windows anyway). Also, we will hopefully have a response to this post in early to mid January. ;)

0.95 is much better, doesn't stretch CPU core to the limit with lowe exponents, only half of the core for ^8192. Also x3 faster for high n.

CUDAGen is somewhere between Genefer or Genefer80 in term of b limits, right?
It may be worth to complite 64-bit version for CUDA (closer to GeneFX64).

I'll try with PRPNet later today.

I've prepared and uploaded it to http://www.uloz.to/7057823/cufft-rar
(it's valid to 2011-01-31)

Just unRAR and put it where CUDAGenefer is and you should be ready to go.

Used only geneferexe=CUDAGenefer.exe and skipped other exe
(this would need client adjustement to incorporate another app for genefer)

Looks like Top b limits for CUDAGenefer are lower than stated in this thread:
maxErr exceeded for 103352^262144+1, 0.5000 > 0.4500

Will try with 524288...

DLL mentioned earlier shoult be at http://pgllr.mine.nu/PRPNet/cufft.rar

CUDAGenefer it quite disk intensive (>2GB of writting for ^262144). I suspect checkpointing is the cause. Should be less frequent for GPU version.

103352^262144+1 is a probable composite. (RES=342b3eab10905202)

MacIntel 32 and 64 CUDA executables (compute capability 1.3) from the 0.95 code have been built by Iain. We are looking for a tester to confirm they are working properly. You can download CUDAGeneferMacIntel.0.95 here: http://pgllr.mine.nu/software/genefer/

Please run it with the -r option, -l option, and then the -b option. And please post your results. The most important is the -r option which should produce matching residues with the following:

    230234^8192+1 is composite. (RES=5972a302c255e081)
    (43927 digits) (err = 0.0024) (time = 0:00:47) 10:38:42
    151902^16384+1 is composite. (RES=0a1a98e69b17f1e9)
    (84895 digits) (err = 0.0024) (time = 0:01:31) 10:40:13
    177444^32768+1 is a probable composite. (RES=f69cc3e2334a43a8)
    (172002 digits) (err = 0.0034) (time = 0:03:19) 10:43:32
    157476^65536+1 is a probable composite. (RES=9f64b3f0d545615c)
    (340605 digits) (err = 0.0042) (time = 0:08:03) 10:51:35
    52186^131072+1 is composite. (RES=1b196d6c0e4d778f)
    (618340 digits) (err = 0.0042) (time = 0:19:14) 11:10:49
    70000^262144+1 is a probable composite. (RES=fa15b4b858fd2ff0)
    (1270114 digits) (err = 0.0042) (time = 0:48:57) 11:59:46


-l option should give you something similar to this:

    Generalized Fermat Number b Limits
    The upper bound m = 8192, b = 2645000, Err = 0.2812
    Starting b = 3340000, Err b = 2650000, Err = 0.3125, 5 Err b = 0
    The upper bound m = 16384, b = 2300000, Err = 0.2969
    Starting b = 2720000, Err b = 2305000, Err = 0.3047, 5 Err b = 0
    The upper bound m = 32768, b = 1870000, Err = 0.2969
    Starting b = 2200000, Err b = 1875000, Err = 0.3125, 5 Err b = 0
    The upper bound m = 65536, b = 1530000, Err = 0.2969
    Starting b = 1790000, Err b = 1535000, Err = 0.3125, 5 Err b = 0
    The upper bound m = 131072, b = 1255000, Err = 0.2969
    Starting b = 1450000, Err b = 1260000, Err = 0.3125, 5 Err b = 0
    The upper bound m = 262144, b = 1000000, Err = 0.2891
    Starting b = 1180000, Err b = 1005000, Err = 0.3125, 5 Err b = 0
    The upper bound m = 524288, b = 815000, Err = 0.2969
    Starting b = 960000, Err b = 820000, Err = 0.3125, 5 Err b = 0
    The upper bound m = 1048576, b = 710000, Err = 0.2891
    Starting b = 780000, Err b = 715000, Err = 0.3281, 5 Err b = 0
    The upper bound m = 2097152, b = 575000, Err = 0.2969
    Starting b = 630000, Err b = 580000, Err = 0.3125, 5 Err b = 0


And finally the -b should give you something like this:

    2009574^8192+1 Time: 314 us/mul. Err: 3.82e-01 51636 digits
    1632282^16384+1 Time: 321 us/mul. Err: 2.53e-01 101791 digits
    1325824^32768+1 Time: 346 us/mul. Err: 2.19e-01 200622 digits
    1076904^65536+1 Time: 425 us/mul. Err: 1.72e-01 395325 digits
    874718^131072+1 Time: 548 us/mul. Err: 3.47e-01 778813 digits
    710492^262144+1 Time: 674 us/mul. Err: 4.21e-01 1533952 digits
    577098^524288+1 Time: 1.08 ms/mul. Err: 2.01e-01 3020555 digits
    468750^1048576+1 Time: 1.91 ms/mul. Err: 1.64e-01 5946413 digits
    380742^2097152+1 Time: 3.65 ms/mul. Err: 3.63e-01 11703432 digits

Quick question...why do some of the tests say "probable composite" and others just "composite"? The Fermat SPRP test as performed by PFGW (and until recently, LLR) gives a definite negative result (it's only for a positive result that there is some uncertainty). Is genefer using an entirely different kind of PRP test (one that actually can produce "probable composite" results)?

"probable" is only depend b value(b^n+1).

Hmm...are you saying that for some values of b it can give only a probable negative result, whereas for others it can give a definite result? (I guess what I'm wondering is, what's the use of the test if it can't give you a definite answer either way? If that is the case, then none of the "probable composite" tests really tell you anything for sure.)

In regard to probable prime and probable composite, on June 17th, 2001 Yves Gallot posted a concern about the accuracy of the FFT transform used in many proving programs, include prime95 used in the Mersenne search.

Based upon his analysis, there was an extremely small possibility that many "proven primes" were actually not totally proven. That is why two different proving programs as used for the final proof of many significant primes.

For a GFN to be called a probable prime, it is actually a prime at the following probability

1 - 1/(GFN number)^2

To be a probable composite, it is a composite at the same probability

1 - 1/(GFN Number)^2

For a 500,000 digit number, the chances of being wrong are so small

1 - 1/(500000 digit number)^2 that I do not worry about being wrong.

In one sense, when genefer says a number is a probable prime, it is proven as the same level as many other programs. Yves was very particular about a proof, so left the final step to a much slower balanced FFT representation.



-------------------

(Yves Gallot posting June 17, 2001)

I wrote a new transform to compute quickly x^2 mod k.2^n+1 which can use any
base W=2^m as internal base representation. Then I tried to find the optimal
value that can be used for primality testing. Today, my conclusion is that
many numbers in the database of prime numbers (even some proven by Proth)
are just some probable primes. Please, read this and tell me what you think
about my reasoning.

First of all, we should define what we call a prime number. The mathematical
definition is not sufficient because we use some computers, some programs or
even some hand computations for the proofs and maths don't indicate what to
do with possible failures. The usage is to use an algorithm which is
mathematically exact and would give the correct answer "N is prime" or "N is
not prime" if the implementation was perfect. To check the correctness of
the implementation, usually we double check the result with an independent
computation (which can use the same hardware and software if the operations
are independent). Then let consider that
(1) N is prime if
- the algorithm used to check primality was proven to give the correct
answer
- and the computation is double-checked with some different operations.

Today, the programs, used for the search for large primes, are based on two
algorithms: a theorem (such as Lucas' theorem or Proth's theorem) and a
transform. Some theorems exist to find some "probable prime" numbers but
they cannot be used because they are not in accordance with (1).

What about the transform? Today fast programs use some floating point FFT.
Let W the base representation, n the length of the transform and i the
number of bits in the mantissa. It is proven that if
(2) W^2 * n * log_2 n < 2^i
then the result is exact (you can find this formula in "Numerical recipes in
C: the art of scientific computing", Cambridge University Press. Some other
formulas exist with a rigorous proof on the maximum error but all of them
generate some closed bounds). The exact bound is unknown and (2) is
pessimistic: the result of the transform is often correct for some W and n
such that (2) is not verified. We can use this remark to write some fast
programs for the search for large probable primes, considering that the
output of the program is "N is a prp" or "I don't know". But if we should
prove the primality (or the converse) of a number, we should use a
transform and a base representation such that (2) (or a similar proven
formula) is true. Otherwise, the algorithm used for the "proof" has no
mathematical proof and because of (1), we cannot write that N is prime.

For example, let a GFN b^32768+1. Then n=16384 and we have i=53.
70906^2 * 16384 * 14 < 2^53 then we can use a simple transform to prove the
primality of 70906^32768+1. But 1041870^2 * 16384 * 14 > 2^53 then if we use
a simple transform for the proof and double check the result with the same
transform, we "just" prove that the probability that 1041870^32768+1 is
prime is 1/(1041870^32768+1)^2. The primality is not mathematically proven.
If we want to complete the proof, we should use a general purpose algorithm
with a 16-bit internal representation.

Let N=k.2^n+1. Today, the length of the transform used by Proth is the
smallest power of 2 larger than n/16 and W=65536. Then the proof is correct
is n < 1,048,576 otherwise the number is just a prp. An internal base
representation smaller than 2^16 should be used for the proof.

According to the base representation used by prime95, can we say that
"2^6972593-1 is prime" or that "the probability that 2^6972593-1 is prime is
1-1/(2^6972593-1)^2"?

I am myself astonished by this result, but I don't see any error in my
reasoning. I think that we (the author of programs) made a terrible
confusion between the search for large prime numbers (maybe I should write
large prp) and the primality proof of these numbers.

Hmm...I'm still a little confused. I understand how probable primes work, and that a PRP is not known for sure to be prime (but nonetheless is quite likely to be) until a deterministic test, such as an N-1/N+1 test as implemented by PFGW or LLR, is performed. Such a PRP test (as I understand it) can only produce two results, PRP or composite (the latter being a definite answer)--assuming, that is, that the computer performing the test is stable and did not make any errors. Am I missing something here? Because if the PRP test works as I understand it, then there should be no such thing as a probable composite (unless you mean it in the sense that it is not known if the computer made an error in the calculation).

There are 2 parts, the mathematics which you seem to understand, and the FFT transform, the shortcut math used in the software. The transform was the item in question. There is an extremely small chance the transform has an error. Read it again about the transform. I am on cell phone now so I cannot re-enter the error formula. Yves was basically challenging the rigor of the proof for the FFT transform used in many primality proving programs including his own. The risk was so infinitesimally small no one ever addressed it.

Ah, that makes sense now. So if I'm understanding you correctly, based on Yves's conclusions, PFGW and LLR (and any other similar programs using FFTs) also produce what could technically be considered "probable composites" at times, but just aren't designed to properly analyze and report that uncertainty?

Did find: /usr/local/cuda/lib/libcufft.dylib: mach-o, but wrong architecture Trace/BPT trap gary%


I'm not sure where the weird "g 230234"... text came from, echoed on the command line, when I tried to run the xxx32 version. I didn't type it. Anyway, when I tried to run the 64 bit version, it wasn't happy with the version of libcufft that it found. I was unable to find any other version of that library on my machine (else I would have changed DYLD_LIBRARY_PATH to include it first), and a quick google search didn't show anything promising.

If I reverse the order of the two DYLD_LIBRARY_PATH directories such that /usr/local/cuda/lib is first, the output of the 32 bit version is a little different:

gary% ./CUDAGeneferMacIntel32 -r GenefX64 2.2.0 (CUDA3.2/MacOS x86) Copyright (C) 2001-2003, Yves Gallot Copyright 2009, Mark Rodenkirch, David Underbakke Copyright (C) 2010, Shoichiro Yamada A program for finding large probable generalized Fermat primes. CUDAGenefer32.cu(193) : cufftSafeCall() CUFFT error. gary% g 230234^8192+1... gary%

The attempt at running the 64 bit version was the same as the first time (bad library).

I'm ready and willing to try attempt #2. Let me know if I've done anything obviously wrong.

Ugh. I just re-read earlier posts in this thread, and #28900 says that one needs a double precision GPU to run this. If that's still the case, then sadly, I'm "down for the count" on this thread (compute capability = 1.1).

I had almost exactly the same problem, only I tried just the 64-bit version.

OSX 10.6.5 (Darwin 10.5.0)
Core i5 2.53GHz (hyperthreaded dual-core)
NViDIA GeForce GT 330M 256MB

dyld: Library not loaded: @rpath/libcufft.dylib Referenced from: /Users/jimmy/Desktop/pgPSA/CUDAGeneferMacIntel.0.95/./CUDAGeneferMacIntel64 Reason: no suitable image found. Did find: /usr/local/cuda/lib/libcufft.dylib: mach-o, but wrong architecture


newb question: I remember there being a reason but don't know what it was - why is the path /./CUDAGenef...; I've never been good at compiling things from source. Terminals and command lines always seem to get the better of me. See username.

Note I have yet to try for real on my 32-bit XP machine. It's a 3.0GHz Pentium 4 but also runs an overclocked GTX 460 with 1GB of RAM (as much as the system...that can't be good can it?)

Did try to compile it on XP before but I think it failed because of something I did. Not quite sure what but I messed up my network settings and that affected everything else somehow. There's a loose capacitor somewhere, I just know it.

Ach of course we need DP. I think that's the first thing that msft told us. Oopsies, we both forgot. Forgot that Apple doesn't work with NViDIA like good business partners. >_>

So now I've gotta try again on the GTX 460 machine of mine. Tomorrow. Currently a bit tired and to be honest I've been reading about number theory all day. Also the GPU is busy ;)

So what Macs do have DP cards? And don't say Mac Pro unless we're also porting to OpenCL with APP. Might not be a bad idea (and is the logical next step) but leveraging CUDA is the first thing.

Anyone got a Mac Pro with a Quadro FX...? I can't honestly think of a system that natively runs both Mac OS X and an NViDIA DP or Fermi card.

Just checked the current options available through the Apple store, and you are correct - there is no DP-capable card available - the MacBook Pros have Geforce 320M or GT 330M, and the Mac Pros and iMacs all have ATI only.

In any case, for future needs, I've recompiled the code to run on any machine running OS 10.5 or later, CUDA 3.2+

January's PRPNet Challenge Project

Taking the lead from rogue's November post about the anniversary of Pierre de Fermat's death, we decided to make January a focus on the PSA's Generalized Fermat Prime Search. The project is offered through PrimeGrid's PRPNet. NOTE: PrimeGrid's BOINC Challenge series doesn't start until 3 February 2011.

The original Generalized Fermat Prime Search by Yves Gallot was very active from 2001-2003. Now a decade later from its debut, it's about time to revitalize the search. Thanks in large part to David Underbakke, Mark Rodenkirch, and Shoichiro Yamada, the GFN prime search is ready to make a comeback.

The month goal will be to find PrimeGrid's first GFN prime. We have 5 deeply sieved files and have yet to find a single GFN prime. The advanced goal will be to find a GFN prime for each of the following N's: 32768, 65536, 262144, 524288.

N=65536; 20 known primes
N=131072 8 known primes
N=262144 1 known prime
N=524288 0 known primes

With the breakthrough of porting Genefer 2.2.0 to the GPU (CUDA), the search has become much more attractive. Testing times for the higher N's have been drastically reduced. NOTE: GPU app requires double precision support.

There will be a PRPNet Challenge in the middle of the month...sometime around the 12th for a few days.

The GFN Prime Search is open to all platforms.


  • CUDAGenefer - used on Windows and Linux64, CUDA 3.2+
  • CUDAGeneferMacIntel - used on MacIntel running OS 10.5 or later, CUDA 3.2+
  • GenefX64 - used on Windows 64
  • Genefer - used on Linux 32&64, Windows 32&64, MacIntel, MacPPC
  • Genefer80 - used on Windows 32&64


However, the CUDAGenefer and GenefX64 applications offer the most efficient testing.

More Details to come.

To John or anyone else in charge,

Just curious where the server and user stats are kept for ports 11002 another GFN port. Looking at this page http://www.primegrid.com/forum_thread.php?id=1215 it does not show that port or the other GFN port.

Note that the newest release of CUDAGenefer only works with PRPNet 4.1.0 clients and 4.1.0 servers. The difference between this release and the previous release is that the previous called itself "genefx64" in code (as seen when using the -v option). The new one calls itself "genefercuda".

Please take note of what rogue says above. If you are upgrading to the new GeneferCUDA, you won't be able to use it with the existing PRPNet servers. You must continue to use the previous version. We are currently testing a newer PRPClient & server which will accept the updated GeneferCUDA.

Since CUDAGenefer has become GeneferCUDA, I changed the name of my build file too. It's now at GeneferCUDA.zip.

PRPNet Update for GeneferCUDA

PRPNet 4.1.0 has been officially released and now includes proper support for GeneferCUDA. Other additions that are of interest to the upcoming GFN Challenge are Team stats.

We'll do our best to update client packages and servers as soon as possible.

server=GFN2:0:2:prpnet.primegrid.com:12003
server=GFN:0:2:prpnet.primegrid.com:12005

What about the test ones?

For now, this can be tested on the following GFN ports:

//server=GFN65536:0:1:prpnet.primegrid.com:12003
//server=GFN262144:0:1:prime2u.com:11002

Not to confirm but...

It would not make much sense running GPU on lower exponent. For example 65635 is about 4x faster on GTX480 comparing to CPU ->quad-core CPU does about the same job as high-end GPU.

I was looking for fast-running through low exponents on GPU (spent a lot of time sieving and PRP testing on low Ns on GFN) but GPUs are good for high exponents.

John, I think we can insert those b<100k for N=262144 which I haven't tested off-line.
(there are about 17k tests, I've tested about 1/3 of them).

Not sure if it's ready for public. If I understood it well, server side needs to be also updated in order to support genefer_CUDA.

It may just be me, but the contents of that package are completely different from what usually comes in the PRPnet packages. I think I will just wait until the links here get updated. I am in no hurry to update to the new version...at least not until I finally manage to get my PPS Sieve badge to silver.

That is a question for both genefercuda, but also PRPNet. I can't answer until someone can tell me if any CUDA app can specify the specific GPU to run on (akin to processor affinity). If so, then PRPNet would need to wait until genefercuda supports a command line option to specify affinity. The change to the PRPNet client is minimal as it already supports that feature for LLR.

My PSieve-CUDA apps can specify the GPU to run on. So it is possible from that standpoint. If "--device" followed by a number is the mechanism used to specify the GPU, that makes it easier to port to BOINC later on.

PRPNet with GeneferCUDA support

We are now ready to start testing. A test server of 4.1.0 has been set up and open to Windows 32/64 as well as Linux 64 clients. Now we just need testers. Please PM me if you are able to help (prior PRPNet experience is recommended). ;)

The current work is preferably for GPU users and is set up for GFN prime search N=262144.

The new PRPNet has the following update:

Version 4.1.0: December 2010 - New Release prpclient: Added teamid= option to the prpclient.ini file. This allows the client to do tests on behalf of a team. Added support for "genefer_cuda" version of genefer. prpserver: Added support for "genefer_cuda" version of genefer. Added support for the team reported by a client. A team ID is captured for each test, thus it is possible for clients (and users) to have some tests for one team and other tests for another team. Added team_stats.html and team_primes.html. Added "Team" column to user_stats.html, user_primes.html, and pending_tests.html. Fixed an issue with inserting GFNs as the value for column c was not set.

Note: Based on current thread discussion, we'll probably have new builds soon to handle multiple GPU's.

Message 30412 - Posted: 5 Jan 2011 | 17:50:38 UTC

I've posted PRPNet 4.1.1 over at my website, http://home.roadrunner.com/~mrodenkirch/prpnet_4.1.1.zip. Since I can't run genefercuda, I am unable to test. If someone can build and test, please let me know if it works as desired.

I also need someone to test against one of the other genefer versions to make sure that I didn't break it for them.

If you only have one GPU, do not specify any value for the affinity.

Note that I just made a quick change to the source because if affinity is in the ini file, but not specified, it would set the device to 0, which might trigger an error in genefer. I don't think it would be an issue, but one never knows...

Mac build updated at http://www.pyramid-productions.net/downloads/GeneferCUDAMacIntel_0.97.tar.gz.

Just found out the Quadro 4000 supports the Mac Pro, as an aftermarket option, so it is possible to run this code after all :) At least if, someone has forked out for the card!

To update to 4.1.1, all that is needed is the prpclient. You can download them here:

These builds should only be used by those participating in the testing. Once testing is over, full packages will be available for everyone. :)

I uploaded a new 4.1.1. I split affinity in the prpclient.ini into cpuaffinity and gpuaffinity and I modified it to not use the -d option with the other versions of genefer.

If someone could give it a spin, I would appreciate it.

I just tryed it and it is not executing on device 1 or gpu 2

Myabe I did not configure it correctly I put the following ni my ini

// This sets the CPU affinity for LLR on multi-CPU machines. It defaults to
// -1, which means that LLR can run on an CPU.
cpuaffinity=

// This sets the GPU affinity for CUDA apps on multi-GPU machines. It defaults to
// -1, which means that the CUDA app can run on an GPU.
gpuaffinity=1

I checked on port GFN32768:100:1:prpnet.primegrid.com:12005

It errored out on GeneferCuda, GeneFX64 and continued using Genefer80 as expected.
CPU affinity still does work.

Message 30504 - Posted: 6 Jan 2011 | 19:04:46 UTC

Hi, I've gone from developer to user. I'm trying to run GeneferCUDA 0.97 on Linux64. I upgraded my Cuda toolkit from 2.3 to 3.2, and I linked libcufft.so.3 to the directory where I'm trying to run GeneferCUDA, which seemed to help. But when I try to run a test (option 2) on device 0 (or nothing), I get:

GeneferCUDA.cu(198) : cudaSafeCall() Runtime API error : unspecified driver error.

My driver is version 256.53, and I really don't want to upgrade because 260.17.* seems quite buggy to me. What is the minimum driver version needed to run GeneferCUDA?

Thanks!

I just tryed it and it is not executing on device 1 or gpu 2

Myabe I did not configure it correctly I put the following ni my ini

// This sets the CPU affinity for LLR on multi-CPU machines. It defaults to
// -1, which means that LLR can run on an CPU.
cpuaffinity=

// This sets the GPU affinity for CUDA apps on multi-GPU machines. It defaults to
// -1, which means that the CUDA app can run on an GPU.
gpuaffinity=1


This is now fixed. I have updated the zip file.

This version also fixes a bug in computing the decimal length of primorials.

It's a part of CUDA Toolkit, IIRC.

Are you talking about cpuaffinity= or gpuaffinity=?

CPU affinity.

CPU affinity is for LLR only. GPU affinity is for genefercuda only. None of the other versions of genefer support the feature.

If I'm not understanding the problem, then I need to understand the specific problem you are encountering and I need to know that it is the latest one that I posted today.

It was CPU affinity for Genefer in latest PRPNet. If it's not supported, I understand why I can't see it.


In 4.1.0 and in my first attempt at 4.1.1, affinity= was used for both. I split that into cpuaffinity= and gpuaffinity=, so you would have needed to update your ini to add those entries and set them.

Hmmm. I don't see anything amiss in the code. How is your ini file configured? I presume that genefer exists in the folder that the client is running in. What is the output when you try to run genefer?

That looks fine, but what is the output when you try to execute genefer.exe?

Is this on Windows or *nix? Are you able to debug?

Running Windows 7 x64.
Genefer benchmark and tests are fine.

But this one gives error, wrong syntax?
Genefer -q 3284106^32768+1

Expression must be in b^m+1 form

Try
Genefer -q 3284106^^32768+1
or
Genefer -q "3284106^32768+1"

It shouldn't matter though because I found and fixed the problem. Please d/l it again.

This syntax works fine, thanks.

PRPnet client now checks with all Genefer apps.

EDIT: Upon aborting client, I choose Report and Abort the rest. It reported fine but afterwards display error "file not found" 5 times.

This is okay. It is just the client trying to clean up temp files from the various apps. If the OS doesn't find the temp files, then it gives the message.

Sieve depths as of 29 August 2010 are:

n = 32768; p=1000P
n = 65536; p=1500P
n = 131072; p=2000P
n = 262144; p=2510P
n = 524288; p=3070P


I haven't done any more sieving since then, ranges are as described above. Do we need to go deeper?
What about lower Ns primality testing? I have done all for N<=2048 up to 100M, N=4096 is up to 6M5.

I've just downloaded the 64 bit Linux PRPclient and started a few tests on my GTX 460 with the 256.53 drivers (CUDA 3.1) since the 260.19.29 drivers are up to 50% slower than the 256.53 ones when running CWPSieve (CUDA).

Successful tests:

230234^8192+1 is composite. (RES=5972a302c255e081)
(43927 digits) (err = 0.0024) (time = 0:00:58) 13:00:09
151902^16384+1 is composite. (RES=0a1a98e69b17f1e9)
(84895 digits) (err = 0.0017) (time = 0:02:01) 13:03:58

The program seems to work despite the drivers are cuda 3.1 ones. I'll probably build a CUDA 3.1 version of GeneferCUDA binary (Linux 64 bit) just to be on the safe side ;)

It seems whenever I terminate the client by pressing ctrl c it stop as normal but when I re start the client it starts the checking process from the beginning. It does not seem to re start the test from when I terminated it. Is this correct
PS in the file there is a .sav file but the prpclient say starting from the .in file

Genefer creates a checkpoint file at certain iterations. I presume genfercuda is doing the same, but I haven't looked at the code. When it restarts, it should start from the checkpoint. That had been tested with the CPU versions of genefer. I cannot speak for genefercuda.

It seems whenever I terminate the client by pressing ctrl c it stop as normal but when I re start the client it starts the checking process from the beginning. It does not seem to re start the test from when I terminated it. Is this correct
PS in the file there is a .sav file but the prpclient say starting from the .in file


Genefer creates a checkpoint file at certain iterations. I presume genfercuda is doing the same, but I haven't looked at the code. When it restarts, it should start from the checkpoint. That had been tested with the CPU versions of genefer. I cannot speak for genefercuda.



Hmm. You are correct the prog creats a genefer.ckpt file but when I restart the prpclient this file disappears and the test just starts fromthe beginning

I have never successfully resumed from either of the two largest GFN (262144, 524288) checkpoints -- you apparently must let them run to completion in one shot!

Just a quick question. I have been working on a GFN number from the GFN524288 and my poor machine is slowly finishing it. Since it is such a big number that I would have quite a bit of time to finish it. But looking at the pending tests for that server.

I see someone else has it 6720^524288+1 is assigned to user: pschoefer.

Just to let everyone know this will be the only one I do for this server, and also it should be done by my calculation sometime late tomorrow night or real early the next morning. Hopefully if I turn it in I will still be able to get credit.

After the ^C, does the .ckpt file still exist? If so, then I would have to defer this to David. He build genefer for x86. He should be able to debug it.

yes for me the .ckpt file still exists but when you restart the client it disappears and then it just starts from the beginning again. Just as described by mfbabb

Ditto ...
Note that it is starting back up using the ".in" file, not the ".ckpt" file as expected.
???
The ".ckpt" file appears to be a binary file.

I updated the client (v4.1.1), so if someone could please d/l and try it out, I would appreciate it. It should no longer delete the checkpoint, but I haven't tested it.

What could happen before is that if there were multiple versions of genefer configured and the first one could not do the test due to a round-off error, it would delete the checkpoint, even if that checkpoint was written by a different version of genefer.

I will work with Shoichiro and David to modify genefer to write genefer.log under certain error conditions so that the PRPNet client can react accordingly. The worst thing that can happen now is that the client can shut down if the log file is not created. As long as you keep don't run into roundoff errors, you shouldn't be experiencing any problems.

Client only files for 4.1.1d can be found here (MacIntel and Windows, Linux64 to come). Just replace the prpclient in your folders.

Just downloaded the 4.1.1d client.
Replaced prpclient.exe in folders.

Still goes to genefer80.exe after control-C, and it starts from beginning.
Doing a second control-C stops genefer80.exe (did not give it time to checkpoint).
Starting again now resumes from a checkpoint.

Win Vista 32-bit.
First control-C should quit, not cause fall-back to next "geneferX" in sequence.

That seems to be a problem. If there is no genefer.log after hitting ^C, then the client should shut down.

I posted 4.1.2 here, http://home.roadrunner.com/~mrodenkirch/prpnet_4.1.2.zip. That should take care of this issue and the other outstanding issues (although I haven't tested it on this particular issue).

Tried to run with GeneferCUDA.exe (on Win XP) and got alert "..failed to start... cudart32_32-16.dll was not found. ..."
Where can I get this?


It's a part of CUDA Toolkit, IIRC.
I've extracted DLL needed to run GeneferCUDA - http://pgllr.mine.nu/PRPNet/cudart.rar


I got the same error but using the dll you posted doesn't fix it...entirely.

Where exactly am I supposed to put it?

-

Edit: You have to manually rename 'em.

Uh ok, so now it recognizes that I have both cuff32_32_16.dll and cudart32_32_16.dll, but I get this:

"The procedure entry point cudaFuncSetCacheConfig could not be located in the dynamic link library cudart32_32_16.dll."

What exactly does that mean? As far as troubleshooting goes, I've hit a wall here.

Edit 2: Actually I don't think I have the toolkit installed. That's odd. Explains why I haven't been able to do much testing (or anything outside of BOINC) though.

Let's see if that solves things. For some reason I don't know if it will. But if it's working for everyone else...

btw, I'm using 32-bit WinXP and have set up the PRP master.ini exactly as it should be to run GeneferCUDA, which I downloaded from Ken's site.

Is that correct, or is there another version? I'm using the 4.11.1d client, if that makes any difference.

Ok. Pardon. What?

Why is this working for other people?

Me:

WinXP 32-bit SP3
Pentium 4 3.0GHz HyperThreaded
1GB system RAM
Zotac GeForce GTX 460 @ 900/1100/1800 (1024MB)

Client I tried was 4.1.1d. GeneferCUDA was 0.97 I think.

It's hard for me to cobble together all these files from across the interwebs. If they could all be in one place with the latest versions clearly marked, that'd be great.

Also it says it can't find cudart32_32_16.dll, so I renamed the included cudart.dll and it seemed to work. Or at least, it didn't give me an error. It did, however, launch two client windows and close them almost immidiately.

Someone please either a) tell me what I did wrong or b) give me a brief walkthrough on how to get GeneferCUDA running correctly over here.

Thanks...!

It's hard for me to cobble together all these files from across the interwebs. If they could all be in one place with the latest versions clearly marked, that'd be great.

Everything that's needed is in the PRPClient packages.

Program versions included

prpclient - Version 4.1.2beta
llr - Version 3.8.4 (Linux, MacIntel, Windows)
pfgw - Version 3.4.4 (Linux, Windows, MacIntel)
phrot - Version 0.72 (MacIntel, MacPPC, PS3)
Genefer - Version 2.2.0 (Linux, Windows, MacIntel, MacPPC)
Genefer80 - Version 2.2.0 (Windows only)
GenefX64 - Version 2.2.0 (Windows 64 bit only)
GeneferCUDA - Version 0.97 (Windows and Linux only)
cudart.dll & cufft.dll (Windows only)

We have yet to pinpoint the "cudart32_32_16.dll" issue.

[EDIT] Windows package now includes cudart32_32_16.dll and cufft32_32_16.dll from the CUDA Toolkit 3.2 XP32 installation.

Glad it turns out I wasn't doing something horribly wrong with my setup. It was pretty vanilla PRPnet with GeneferCUDA dropped in from Lennart's site.

I suppose I had downloaded the wrong files from some of the wrong places, or something like that. I'll hold off on trying to fix this myself until a stable client is released and GeneferCUDA is fully supported. Then it's on to PSA for me. ;)

Hi, I've got that problem:

Start test of file 'work_GFN32768.in' - 01:05:59
GeneferCUDA.cu(216) : cufftSafeCall() CUFFT error.


What is a problem in that function?

Your NVIDIA graphics card (9500GT) is not DP capable.

Ok I've downloaded that - will test in approximately 5 minutes as I'm waiting on a DNETC thing to get out of my GPU and leave it free for testing this.

In my problem above (or somewhere, I guess I posted it here) should note it does benchmark fine. Let's see if this client fixes it!

EDIT:

It works! Well...sorta.

You have to copy and paste cudart32_32_16.dll and cufft32_32_16.dll into prpclient-1 and prpclient-2 (or however many folders you have).

Now for the odd stuff...It just uses my CPU unless I go and comment out genefer.exe and genefer80.exe.

Ok so that's done. Now Task Manager shows 2 instances of GeneferCUDA (um I only have one GPU!) But luckily, GPU-Z shows 99% load at full clocks (oc'd a ton)

I'm seeing big numbers on the screen. Is this good? :D

Testing 5744^262144+1... 3264512 steps to go maxErr exceeded for 5744^262144+1, 0.5000 > 0.4500 PRP: 1*5744^262144+1 5000/3273612


It would appear as though I am running two "tasks" at once on my GTX 460. Not that I'm concerned, but what kinda timeframe am I looking at, exactly?

And thanks a lot for whatever you did that made it work, John et al ;)

Oof. 202500/3273612. I'm just gonna checkpoint it and run BOINC stuff overnight. I'm oddly rather tired, but I've the day off tomorrow to enjoy the snow whilst helping y'all finish testing this. Well...super-expediently, given the challenge starts in a half hour by my clock here.

Bottom line: it is working for me and hopefully everyone else who had similar problems. Thanks! I'll let you know results sometime tomorrow. Chances are someone else will have by then, but just for now:

Pentium 4 3.0GHz / HT
1GB system RAM
WinXP 32-bit SP3
NViDIA GeForce GTX 460 @ 910/1100/1800

Looks as though it will take a little over an hour for this test. Checkpointing now and will get back to you later.

You asked if anyone's tested it, so far I have and I'm sure others have too. ;)

Bear in mind that a) it tries to run two at once on a dual install, and probably 4 on a quad, etc...even if you have just one GPU. Looks like one task just kinda hangs there while the other powers through. b) you must copy the two .dlls to the prpclient-1 and prpclient-2 etc folders in order for the app to work.

Nice.

My solution: Two PRPnet directories: 1 installation ("single") for the GPU and one ("quad") for the CPU ;)

How's the cuda3.2 -vs- 3.1 issue from your earlier post? I'm considering
switching the tesla 2s from proth_sieving, but unlikely to be able to load
drivers without sysadmin help (I don't own the machine/beast). Two cards.

The Genefer CUDA app reports as GenferCUDA 0.97 (CUDA3.2) but also worked with driver version 256.53 and the CUDA 3.1 SDK installed. I tested this on the test port GFN262144TEST. Currently I've installed driver version 260.19.29 and the CUDA 3.2 SDK. Everything is running fine.

BTW: Since the app seems to do DP processing it would be interesting to see the performance of some Teslas compared to their consumer counterparts.

BTW2: A test run of llrCUDA on them would be interesting too ;)

Question: Running PRPNet on a Windows Server 2003 (32 bit) that has never been part of Boinc or Primegrid.

Since Prpnet is a manual run, can I run it on a server that I can't get Boinc to run on and still have it work and have the credit applied to Primegrid? My thought was to install the apps but fake the client id to one of the pc's I do have on Boinc.

Question: Running PRPNet on a Windows Server 2003 (32 bit) that has never been part of Boinc or Primegrid.

Since Prpnet is a manual run, can I run it on a server that I can't get Boinc to run on and still have it work and have the credit applied to Primegrid? My thought was to install the apps but fake the client id to one of the pc's I do have on Boinc.

PSA credits are added to the BOINC credits but not to a special PC that is listed in your computer list. As long as the admins can connect the PRPnet user with a BOINC user everything (email) should be fine.

thanks !!! will give it a go since I can't seem to get Boinc to run on the server even though I know others have found a way to work around the issue.

I found a bug where the client reports the wrong version of genefer to the server when a test is completed. I'll send out a patch tonight or tomorrow.

If you look into the work_GFN524288.save file and don't find an entry for it there: Yes. It still appears here:
