msieve 1.45 windows binary and GPU (-np)?

Andi47 · 2010-06-16, 17:53

I have just downloaded the windows binary of msieve 1.45. Some questions:

Is this version able to do -np on the GPU? (my GForce GTS 250 should be CUDA-enabled) What will msieve 1.45 do by default for poly search? GPU or CPU? Is there a flag which I can type in the command line to force it to either one?

To use a GPU you have to use the GPU-enabled precompiled binary from the sourceforge page. That will use only the GPU to select polynomials; you use -np just like before.
