What card and CUDA version are you using? Do you run the binary from command line, from the directory above the one with the PTX files?

using GPU 0 (GeForce GTX 1050 Ti) selected card has CUDA arch 6.1
win 8.1 x64
all ptx-file in same directory
run from python script

It sounds like the stage1_core_sm60.ptx file is missing. (or sm61 ?)

You will have to add that to the "make" file and rebuild or find another binary which includes this later ptx file.

the card support a low version of the ptx-files.

I don't know how to tell msieve to use a lower version ptx-file.

Perhaps this [url=https://www.mersenneforum.org/showthread.php?t=23685]thread[/url] is helpful or post your question/request there.

I had the same problem with a arch 7.5 card. In msieve's source file stage1_sieve_gpu.c file, starting at line 1106, is this code:

[CODE]if (d->gpu_info->compute_version_major == 2) {
CUDA_TRY(cuModuleLoad(&t->gpu_module, "stage1_core_sm20.ptx"))
}
else if (d->gpu_info->compute_version_major == 3) {
if (d->gpu_info->compute_version_minor < 5)
CUDA_TRY(cuModuleLoad(&t->gpu_module, "stage1_core_sm30.ptx"))
else
CUDA_TRY(cuModuleLoad(&t->gpu_module, "stage1_core_sm35.ptx"))
}
else if (d->gpu_info->compute_version_major >= 5) {
CUDA_TRY(cuModuleLoad(&t->gpu_module, "stage1_core_sm50.ptx"))
}
else
{
printf("sorry, Nvidia doesn't want to support your card\n");
exit(-1);
}
[/CODE]

Which for anything at or above compute capability 5 attempts to load stage1_core_sm50.ptx.

I tried the following, which gets past the error message but appears to hang once the card gets going:

1) edit gpu_sm.props in the build.cuda.vc15 directory to update the CC_major and CC_minor fields (mine were 7 and 5)
2) in visual studio, edit the stage1_core_sm property pages by adding compute_75,sm_75 to the Code Generation item of the CUDA C/C++ section (or in your case, I guess compute_61,sm_61)
3) rebuild

This will make a stage1_core_sm61.ptx file in the bin/ directory alongside the msieve.exe executable. You'll then have to rename to stage1_core_sm50.ptx for it to be loaded by the code above.

But, like I said, some step or another is still missing because the code now just hangs after starting the search.

I think I've included all the necessary .dlls, but do reply if you miss any. Very little testing done, but enjoy.

P.S. I've included zlib, since I like to keep the relations compressed (.gz) and don't want to unzip a few GBs of relations when I post-process NFS@home jobs.[/QUOTE]
Is SVN 1028 still the latest version of M Sleve for Windows 10 64-bit?
Thanks
