Default Feromant performance

So I did some test with Feromant. On a gtx 750 Ti, the CUDA version seem to go 10 time faster thaan my CPU (i5-2400k)

F CUDA normal
41 286,375,579 28,615,901
81 137,500,927 14,298,381
161 80,650,011 7,125,026
321 36,940,695 2,388,966
479 14,139,185 705,062

F479 is the highest i could use the cuda version without crashing.

Consider that Feromant_CUDA uses one CPU core for the sieving.

Hi All!
I have the results of some calculations on different equipment. I think they will be useful.

The program has not been tested for generation Pascal GPU, so I would be interested in information about timings and whether program test run (from a file _worktodo_factors).

Yes, the program fails when the speed is below 15M/sec

Can you build a linux CUDA binary (or let someone trusted build it and have it sent back to you, so then you could distribute the binary)? I'd be happy to help.

I plan on posting the source code for public use later.
