Sam asked me to queue these smaller but needed numbers for NFS@Home. Unfortunately my cluster with the GPU nodes is down right now and I don't have time to address it for a bit. I would appreciate appropriate polys for these numbers. Thanks!

I will start on C181_133_103 and move on to the Cunninghams afterwards (assuming no one else hasn't already taken them, which honestly I consider unlikely).

I will start msieve-gpu on the C190 beginning at 25M. I am only in town for a little more than a week. My GTX 560 Ti can't do much but maybe I can set a low level baseline to beat. Or get lucky.

VBCurtis · 2016-08-05, 04:16

I'll also have a go on the C190, starting at 1M till 5M (or I'll update if I proceed past 5M).

VBCurtis · 2016-08-06, 20:56

36 hr, best on the C190 are 1.85 and 1.82. If we get two in the 1.90's for test-sieving, that should be good enough.

RichD · 2016-08-07, 23:06

Nothing close on the C190. My best is 1.73. I'll keep running past 30M until I leave town later this week. I'll only post something of significance.

RichD · 2016-08-11, 19:42

The best poly I got on the C190 is 1.861. I'll be closing up shop for a few weeks while I am out of town.

VBCurtis · 2016-08-11, 20:34

Rich-
you should post your 1.86, it's at least as good as mine.
7,401- C190, I root-sieved about 400 hits of 4e25 or better (stage 2).

I tested A1 from 1M to 2.1M.
Between Rich and I, we ran about 12 GPU-days, pretty weak for a composite this big. I can give it more GPU time after the weekend if desired.

RichD · 2016-08-11, 20:45

OK, I was only running mine about half-time.
