Cool.
There was a 170 bit composite factor found via P1 recently. http://www.mersenne.org/report_expon...2259013&full=1 82 and 88 bits for the factors

Thanks to the venerable MadPoo for helping me figure out a numa issue with some new servers by using AffinityScramble2, I've currently got the ability to bring in 32 100M digit exponents every ~50 days. (at least until these servers get used for something.)
edit: that is, once they start LL. Last fiddled with by aurashift on 20160224 at 19:33 Reason: I wanted to.

I have a good feeling about 333,333,223 and 333,333,307. Or I just think they look neat. About 25 days before we start seeing results... lost 6 blades to projects (12 sockets)

So, if it is one exponent per blade, each blade is 1520% faster than a Titan [at the 100M digit range LL], plus the ECC memory benefit. If it is two exponents per blade, then it is another 50% faster.
What does a system with 32 such blades cost? What does a system with 16 such blades cost? Last fiddled with by TObject on 20160323 at 00:29

As for cost... let's just say metric fktons. (...really...at 1632 the blades and the infrastructure...hmm...think cost of a house. I'm privileged to get to use these until they get provisioned.) I'm glad you commented, I was just wondering what the GPUs could do in the 100M range the other day... Last fiddled with by aurashift on 20160323 at 02:55

Yea, a Titan (the original, nonoverclocked) does a 100M digit exponent in about 60 days (maybe a few days less if you are willing to be more adventurous with FFT sizes), with current CudaLucas. But it is really better to run two sideby side and compare residues along the way.
Cool info on the blades. I need to win a lottery, pronto; so I can get some. ;) Last fiddled with by TObject on 20160323 at 18:40
