[QUOTE=swellman;433053]Ryan is working C184_135_106 via GNFS.

He seems to have almost unlimited sieving capacity - he sieved this job in just a few hours[/QUOTE]


:shock:

:shock:


That's an order of magnitude more throughput than all of NFS@Home. That's approaching NSA-like capabilities... that's an order of magnitude less than a top 500 super computer. (I estimate a Sandy Bridge core to be around 5 Gflops, he has at least 5 Tflops available to him, maybe more than 10, and top500 entry barrier is just north of 200 Tflops)

C181_135_109 polynomial selection complete (9.5 days on GTX1080 plus a few CPU-days for the later stages), job has been queued on nfs@home 15e.

Murphy value for best-sieving polynomial is 7.801e-14

That's quite the gap. How many polys did you test sieve? How many total had a better score than the actual winner?

[QUOTE=Dubslow;439968]That's quite the gap. How many polys did you test sieve? How many total had a better score than the actual winner?[/QUOTE]

I test-sieved the 32 best E-scores, which were from 5.826e-14 to 6.929e-14; the fastest-sieving one had the second-best E score.

I'll take it.

I factored it on Aug 27: [url]http://www.mersenneforum.org/showpost.php?p=440875&postcount=118[/url]

Ok, thanks.

Ugh! Sorry. Forgot to remove it from the yoyo queue.
