There is a small bug, if you imput a 'not prime' exponent in the worktodo. It enter in a ' MXXX is not prime' loop and doesn't get the next assignment.

Hi,

Yepp, allready known: [url]http://mersenneforum.org/showpost.php?p=245285&postcount=511[/url]

and fixed in my current development version. :smile:
Anyway thank you for reporting issues.

mfaktc 0.15 is planned as pure bugfix release, this should not take too much time to release, just give me some weeks.

[QUOTE=Karl M Johnson;248909]Amphoria, what were the drivers you compiled mfakt under ? The toolkit/sdk was 3.1, for sure.[/QUOTE]

As others have surmised the driver I use on Windows is 260.99. However, I am surprised that the binary cares what runtime I am using, only the CUDA toolkit version. In fact the win32 binaries are compiled on a PC that doesn't even have an Nvidia card installed.

What I did forget to include in the zip files was the cudart dll. I can re-upload with these if it would help.

mfackt is really quick... time to TF 66->67 of a M80xxxxxx exponent is 4 Minute and 23 sec

What a pity
 

My new notebook GPU "Geforce 540M" is not (yet) supported by CUDA drivers. I tried CUDA 3.2 (260.99) and it said somthing like "no compatible hardware". There are even no non-CUDA drivers at Nvidia available. Preinstalled is 265.83.
I will wait... How long to next CUDA release..?

I remember something like this happening when trying to get CUDA working on my 320M-equipped laptop but can't now remember the exact work around. It certainly involved installing a CUDA driver which wasn't "supported" but which still "worked". A Google search of the forums, especially the nVidia CUDA forum, will reveal what I did.

Good luck!

One last try
 

If I read it correctly I do have a CUDA driver (see below). Do I really have to install the CUDA 3.2 toolkit only for running the app? Or should the driver file be sufficient?
I also appended the mfaktc 0.14 error message from the provided Win64 build. It names the missing dll file. Any thoughts appreciated... Tnx.

I'm also getting "cudaStreamCreate() failed for stream 0 ." on a brand new Win7 64-bit build with a GTX 460.

I downloaded Amphoria's pre-built Window binary and the DLL from his previous pre-built binary.

Suggestions?

the cuda toolkit ?

[QUOTE=firejuggler;250526]the cuda toolkit ?[/QUOTE]

Beats me. I didn't download any CUDA-specific stuff. I just figured a binary would work without any further downloads.
