Do Nvidia qualifies, or must be AMD card?
If it does, tell me what to do.

I don't know if I forked from an nVidia-capable gpuowl version. Best would probably be an AMD gpu. If no volunteers appear, we'll revisit your kind offer.

Judging by file dates and help output, it looks to be a variant of v6.5. Is there a particular -use that your requested test requires? FYI it does compile and run on NVIDIA.

For the same 87M exponent, starting from zero, each separate folder:

Win7 Pro x64, RX480, GW variant:

Code:

>gpuowl-win -h
2019-09-14 11:10:12 gpuowl

Command line options:

-dir <folder>      : specify work directory (containing worktodo.txt, results.txt, config.txt, gpuowl.log)
-user <name>       : specify the user name.
-cpu  <name>       : specify the hardware name.
-time              : display kernel profiling information.
-fft <size>        : specify FFT size, such as: 5000K, 4M, +2, -1.
-block <value>     : PRP GEC block size. Default 1000. Smaller block is slower but detects errors sooner.
-log <step>        : log every <step> iterations, default 20000. Multiple of 10000.
-carry long|short  : force carry type. Short carry may be faster, but requires high bits/word.
-B1                : P-1 B1 bound, default 500000
-B2                : P-1 B2 bound, default B1 * 30
-rB2               : ratio of B2 to B1. Default 30, used only if B2 is not explicitly set
-prp <exponent>    : run a single PRP test and exit, ignoring worktodo.txt
-pm1 <exponent>    : run a single P-1 test and exit, ignoring worktodo.txt
-results <file>    : name of results file, default 'results.txt'
-iters <N>         : run next PRP test for <N> iterations and exit. Multiple of 10000.
-use NEW_FFT8,OLD_FFT5,NEW_FFT10: comma separated list of defines, see the #if tests in gpuowl.cl (used for perf tuning).
-device <N>        : select a specific device:
 0 : Ellesmere-36x1266-@28:0.0 Radeon (TM) RX 480 Graphics
 1 : gfx804-8x1203-@3:0.0 Radeon 550 Series

So it is slower. Thanks for the data.

Oddly the -time option shows my variant spending less time in fftMiddleIn than the production version spends in TransposeW + fftMiddleIn. So -time says it should be faster but the wall clock shows it isn't.

Back to the drawing board.

You're welcome. On GTX1080Ti it seems very close. There may be gpus where it is faster now.

Be careful what you ask for?

Code:

>gpuowl-win -h
2019-09-14 13:24:58 gpuowl v6.10-0-gc1d0025

Command line options:

-dir <folder>      : specify work directory (containing worktodo.txt, results.txt, config.txt, gpuowl.log)
-user <name>       : specify the user name.
-cpu  <name>       : specify the hardware name.
-time              : display kernel profiling information.
-fft <size>        : specify FFT size, such as: 5000K, 4M, +2, -1.
-block <value>     : PRP GEC block size. Default 500. Smaller block is slower but detects errors sooner.
-log <step>        : log every <step> iterations, default 50000. Multiple of 10000.
-carry long|short  : force carry type. Short carry may be faster, but requires high bits/word.
-B1                : P-1 B1 bound, default 500000
-B2                : P-1 B2 bound, default B1 * 30
-rB2               : ratio of B2 to B1. Default 30, used only if B2 is not explicitly set
-prp <exponent>    : run a single PRP test and exit, ignoring worktodo.txt
-pm1 <exponent>    : run a single P-1 test and exit, ignoring worktodo.txt
-results <file>    : name of results file, default 'results.txt'
-iters <N>         : run next PRP test for <N> iterations and exit. Multiple of 10000.
-maxAlloc          : limit GPU memory usage to this value in MB
-use NEW_FFT8,OLD_FFT5,NEW_FFT10: comma separated list of defines, see the #if tests in gpuowl.cl (used for perf tuning).
-device <N>        : select a specific device:
 0 : Ellesmere-36@1266-28:00.0 Radeon (TM) RX 480 Graphics
 1 : gfx804-8@1203-03:00.0 Radeon 550 Series

Bug report, but not P-1: Gerbicz error count not reported in JSON result.

It used to, see this commit:

https://github.com/preda/gpuowl/comm...37df13563a0f0f

I suspect that what is needed is a boolean, indicating whether the PRP test was was done with/without the Gerbicz error check. Would a bool be enough? Given that gpuowl never did PRP without GEC, that bool is always true for GpuOwl (i.e. implied by the program info, which is part of the result).

My dislike of "error-count" is caused by the fact that, with GEC and roll-backs, the error-count of the result is always 0, as there is no error *included* in the chain of computation begin-to-result. Let me give an example:

Let's say the user start a PRP test of some exponent N. At 50% in the test, a GEC error is detected. The user now starts a whole new PRP(N) test again, from the beginning (e.g. by deleting all the savefiles for N). This second test runs to completion without incident. What should the error-count reported in the result of the second test be? (I suppose 0?)

But what if the user, when a GEC error is detected at 50%, instead of starting from the beginnig (0%) starts from a savefile at 10%, and the computation runs without incident to completion, what should the error-count be? (the savefile at 10% is GEC verified good) Again I suppose 0, beause there was no error in this test result -- no error from beginning to 10%, and no error from 10% to end.

But what the software does automatically on a GEC error is similar to that user restarting from 10% -- it loads a good savefile, verified, with 0 errors in it, and runs from there to completion without incident (or cancels the test and starts another in the case of another GEC error, etc).

[Another way to see it, is that the state of a test should be contained fully in the savefile. Loading a savefile, manually or on a rollback, should re-instate the state from the savefile. In addition, GpuOwl never creates a savefile that didn't pass GEC. Reasoning this way, an "error-count" that is stored in the savefile can never be different from 0]

I suppose it would not be useful if GpuOwl added invariably an information "error-count":"0" to every PRP result?

Another problem is that GEC errors can also originate from a too-small FFT size (in GpuOwl's case), but that is no indication on the health of the hardware.

Is the goal to put a bearing on the "health" of a particular GPU? -- but that would still not affect the validity of the PRP result. And the health of a GPU is not limited to a single test -- e.g. a GPU that often produces GEC errors may still have full runs without errors from time to time, how does that affect the reliability of the result?

So, is in fact what is needed a bool indicating whether the GEC was performed or not?

The nonzero integer count of GEC errors detected during a run is still useful information. It indicates a confounded combination of hardware issues affecting raw reliability and throughput, and fft length exponent limits allowing roundoff error to generate significant error. That is useful information even if the errors are detected and corrected by retries and so the gpuowl result is only delayed and otherwise unaffected. The delay effect can be considerable. I have seen a case in prime95 where the hardware was so unreliable that progress in PRP/GEC could no longer be made. In one gpuowl V1.9 case there was a GEC error count of around 150, when near the stated limits of its fft lengths. A gpu or cpu that generates a lot of PRP GEC errors should not be running LL with or without the Jacobi check. Not all users examine logs or console for clues to error rate. Omitting detected error count from results makes it easier for the less attentive users to submit results from less reliable hardware and remain unaware their hardware is unreliable.

The count is useful for two reasons that I can see:

1) It lets the user monitor hardware health. This is especially nice for headless operations. Rather than ssh into each GPU machine and grepping the log files, I can program the server to email a user whenever a non-zero error count is reported (this feature exists now for prime95 LL tests).

2) It lets us spot double check these PRP results someday. The first prime95 implementation had some windows of vulnerability. If there any vulnerabilities remaining, these machines would be the most likely to find them.

Approximately reproduced in 6.10-1. Renaming to a filename that already exists, in this case in subfolder <exponent> is a problem.

Code:

>gpuowl-win -h
2019-09-15 09:55:59 gpuowl v6.10-1-gea7d51c

Command line options:

-dir <folder>      : specify work directory (containing worktodo.txt, results.txt, config.txt, gpuowl.log)

Worktodo for anyone to try reproducing it:

Code:

B1=220000,B2=3960000;PFactor=0,1,2,24000577,-1,76,2
PRP=0,1,2,1257787,-1,70,0

The PFactor line is probably unnecessary. V6.10-0 did the same; 3 files, then boom. Also note that both V6.10-0 and 6.10-1 left a worktodo.bak behind. There may be a similar rename to existing filename issue with the worktodo file. I vaguely recall there being an issue like this rename fail due to existing target filenamewith gpuowl some months back.

Prime95 P90 years forever! Aug 2002 Yeehaw, FL 1110101101111₂ Posts	So it is slower. Thanks for the data. Oddly the -time option shows my variant spending less time in fftMiddleIn than the production version spends in TransposeW + fftMiddleIn. So -time says it should be faster but the wall clock shows it isn't. Back to the drawing board.
