Happy factoring,

I have tried to run the windows version from Sourceforge.

After initial problems of missing b40c directory and files (cured by finding a copy in an earlier version of msieve binary package) I am now stuck with a runtime error :-

 
e:\MSieve152GPU>msieve152_gpu -g 0 -np
deadline: 1600 CPU-seconds per coefficient
error (line 1080): CUDA_ERROR_FILE_NOT_FOUND
e:\MSieve152GPU>

msieve.log contains the following :-

Anyone know what's missing, and where I can get a copy?

[jasonp]

Do you also have the sort_engine_*.dll files in a subdirectory or your DLL path? What CUDA version are you using?

[Andi_HB]

Same for me, i have this files:

cudart64_55.dll
msieve.exe
pthreadvc2.dll
sort_engine_sm20.dll
stage1_core_sm20
worktodo.ini

[jasonp]

Does the v5.5 runtime library have difficulty when the CUDA driver interface version is higher?

ok I added sm11 and sm13 dlls into the directory (and the .ptx files) and the problem moved : -

deadline: 1600 CPU-seconds per coefficient
randomizing rational coefficient: using piece #1 of 3
coeff 12 specialq 1 - 18521435 other 180742 - 433783
error (line 734): CUDA_ERROR_LAUNCH_FAILED

My system reports CUDA 7.0.23 driver.

[wombatman]

Are the dlls and the msieve exe the same file type (i.e., both 32-bit or both 64-bit)?

Good call ,
I'd picked up the 64bit sort_engine dlls by mistake - all sorted and running now, thanks.

[wombatman]

You bet! I had the same issue in the past, so I figured it wouldn't hurt to ask.

[BfoX]

just add x32 if any1 want it ;)

Would it be possible for you to compile a x64 version that is compiled for core 2? All the recent builds seem to use an instruction that my cpu doesn't have.
