prime numbers

(1/1)

daydreamer2:
there is norwegian tvshow about numbers and in one episode he interviewed a guy who got a silverprice for the second biggest prime, he had left his computer on from 1996

would it be possible to speed it up with help of SIMD and a 64bit cpu having much more registers?
hopefully use a algorithm do the calculation and if you have a 8cores you use those+maybe pixelshaders
and run a custom minimum OS to that has no windoze etc that takes Resources and maximum ram

aw27:
I factored a 156-digit number with GGNFS back in 2010 and is still in 18th place in this site (the alias is JPascoa).
It took a few months, I can't remember now how many but around 8, but was not continuous. I had 6 CPU threads working on that from a total of 8. I have not used CUDA because it freezed the machine.
