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 fixedk nonbase2 GPU sieve similar to srsieve

An excellent reward for three years of persistence. 8579*10^3732601 seems to have been your previous R10 prime...

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. Last fiddled with by henryzz on 20130701 at 22:33
