The P-1 factoring CUDA program - Page 60

I have some issues getting Stage 2 going with the 0.22 version. It starts filling the GPU memory all the way to 9200 mb, then juist quits (CMD window closes). I'm using a GTX 1080 Ti with 11GB memory. (Windows 10 Home x64, driver 411.70)

CMD output:

If you're running it by double-clicking the exe then any message it may give when it terminates would be unfortunately lost. If you open a command prompt first and then run the program, any final error message output (if any) would remain visible.

Tried that, no message what so ever. It just terminates.

That's not unusual for CUDAPm1 v0.20, even with console redirection to a file. As I recall the original author owftheevil posted about certain error cases terminating with no message. In my notes, post 373 2013-09-23 win64 cuda5.5 version attached, discussion of fftbench parameters & threadbench.
"excessive stage 2 round-off errors simply halt the program without error messages."
"there could be some inefficient fft lengths that I haven't looked at yet, which will cause a test to terminate with an excessive round-off error."

The memory filling to 9.2GB on a mere 90m exponent is news.
On Quadro 2000,V0.20, I had issues completing exponents at 85m on one unit and not another. Also at 171m.

Interesting, and a possible new issue.

That exponent 89326001 has no P-1 assignment listed and is not available for assignment. https://www.mersenne.org/report_expo...exp_hi=&full=1
I could try it here for confirmation and maybe isolation of what environment(s) it occurs in. What was the worktodo entry for it? I suspect it was something like
PFactor=1,2,89326001,-1,76,2

I have reserved the exponent through GPU72.com.
Worktodo does indeed look like this:

Quote:

Pfactor=N/A,1,2,89326001,-1,76,2

A few assignments were completed from GPU72.com before this one. Funny thing was dat similar exponents in the 89M range only used roughly 4300MB memory.

FYI, it completed ok here on Win7 x64 CUDA5.5 build V0.20, driver 378.78 in about 2 hours on a GTX 1080 Ti. I'll try closer to your case later.

Code:

In prior windows releases, this program would not make use of more than 4GiB video ram. I released that restriction for this build, because I found no issues with it on my 8GiB RTX 2070. The only other cards I had available were 3GiB and 2GiB, so I didn't bother trying them.

Noticing that you have a device with 11GiB, I'm very curious to find out if there was another reason for this limitation that I hadn't been able to determine. Especially since you mention it "starts filling the GPU memory", which it's trying to malloc, and failing.

If you could please do me a favour and fiddle with the UnusedMem value in the .ini file, and see if you can determine a value that doesn't crash. I would start with a value something like 7168, as that would simulate the old 4GiB limitation. (11GiB - 4GiB = 7GiB * 1024 = 7168)

Interesting benchmarking, followed by a silent halt.

it was an attempt to continue a run that had a silent halt in v0.20. V0.22 did too.
