There have been a few good P-1 factors found, mainly by Aurashift.

Cool.

There was a 170 bit composite factor found via P-1 recently.

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.

sure, but there's a vetting process and registration fee.

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 15-20% 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?

It is a single blade with two sockets, which can handle two exponents. Each socket has 16 physical cores (this model anyway...you can max out at 18 cores per socket right now).

As for cost... let's just say metric fktons. (...really...at 16-32 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...

Thumbs up

Yea, a Titan (the original, non-overclocked) 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 side-by side and compare residues along the way.

Cool info on the blades. I need to win a lottery, pronto; so I can get some. ;)

There has been some serious firepower thrown at this range of late. Note the rise in expos taken to 80 bits.
We are now over 61% factored out for the 332M range as a whole.
