Nice one Borys - 93 on the big list

CRUS's largest to date and R10 is now a 1ker

The depressing part is that I calculate only 19.56% chance of a prime by n=2M for r10.

What is really needed is a fixed-k non-base-2 GPU sieve similar to srsieve

An excellent reward for three years of persistence. 8579*10^373260-1 seems to have been your previous R10 prime...

Unfortunately we are a way from doing that. BSGS needs too much memory so the GPU is not practical. Memory light methods are not very smooth.

This has been discussed in the past.
http://www.mersenneforum.org/showthr...ht=bsgs&page=3
Is the memory usage dependent on p or the range of p?
Also you talk about needing 256 sets of 80MB data as there are 256 cores. Is there a way to utilize multiple cores on the same set of data?
Another option is to make it use only a few cores(as many as possible) and expect the user to also run a thread of mfaktc to saturate the gpu.
