Just a quick progress report. Stage 2 is coming along nicely. Referring to (p*k)^e - rp^e, it understands different values of e and p, I'm teaching it about rp now. Then its just a matter of choreography and logistics. The general multiplication kernel is functioning properly, a quick and dirty test on M51943429 with b1 = 1248, b2 = 1249, e = 2, and p = 6 found the factor.

I realize your work is still under development, but I have to ask if CudaP-1 will have a similar configuration/.INI to MFAKTO/C. Of course, I ask this to determine or sway its development to ensure MISFIT can easily work with the final product. Ideally MISFIT for MFAKTO/C would be able to front CudaP-1 with only minor changes.


Thanks

CUDA P-1 is stil under development, and AFAIK (and have tested) there is still no user interface (though I found arecall to a !worktodo" file).

I expect that the final versio should be similar to either Mfakt? or CudaLucas to be usable with manual reservations.

The "final" version should be easy to make work the same way as CUDALucas, seeing as it's a CUDALucas conversion.

I suppose there is only a linux version atm?

flash/Brain ought to be able to compile it for Winbloze.

That would be very nice. I got one GTX 590 and one GTX 570 running full speed, P-1 could be a nice addition to that :smile:

No Windows compile
 

[QUOTE=Dubslow;332825]flash/Brain ought to be able to compile it for Winbloze.[/QUOTE]
I cannot compile for Windows for at least 2 reasons:
- #include <gmp.h> fails. Changed to "gmp.h" but I have no Windows GMP library, only the header file gmp.h
- #include <cuda_safecalls.h> fails
I could make an investigation but don't have much time and I'm no linker expert. If anybody else can offer/point to precompiled libs and a suitable VC10 makefile...

Hmm... I'm decently certain that the cuda_safecalls.h is included in CUDALucas as well, but I'm absolutely certain that the GMP dependency is new to P-1. You or others who desire a compilation ought to ask Brian Gladman for help; he's the forum's resident Windows/VS/GMP-for-Windows-aka-MPIR expert. :smile:

Question.

How is the GPU memory use computed, related to exponent, B1 and B2?

In other words, how can I know if B1 and B2 ranges fit in my GPU memory?
