GNFS targets which need more ECM - Page 9

fivemack · 2016-08-11, 14:41

I have started 12800@3e8 on C200_139_113 which should take about two weeks (it's running on half a GTX1080, the other half of which is doing cudalucas - the GTX1080 is really a very fast device, flat-out it's about equivalent to 8 cores Xeon Haswell at cudalucas). I think it deserves 38400@3e8 before going to polynomial selection.

I've decreased the amount of ECM in the work-to-do table: http://www.mersenneforum.org/showpos...30&postcount=1

Yes t55 should be enough. Thanks for queuing it.

Stage 2 run for full t55 with no factors found. Guess it's ready for yoyo@Home?

Either way, releasing number.

I'm currently running Stage 2 of t55 for C183_138_97 and C179_148_87. Results expected before the end of the month.

Just to change it up a bit, reserving C200_139_113 for Stage 1 curves. Will do 18k at B1 = 110M.

Cough cough😎

Knew I should have searched the thread first. Whoops.

Will instead work on C183_144_73. I searched the thread and no claims came up, so hopefully this one will be alright!

Completely factored using ecm_gpu for stage 1.
