Back from my trip, will get something on the C162, starting at 50M

VBCurtis · 2013-09-19, 06:42

I'll start tomorrow at 34M.

Here's an initial result from running overnight:

And here's one that's a bit better and is just shy of the expected range:

I got a 9.53 from my first 24h, so this composite is easy to find 9.5-9.7 polys for. We've often had one hit (perhaps a couple of polys) score 10% or more higher than our next-best, so I think 1.05-1.10 should be considered required on this one.

I think 15-20 GPU days is about right for poly select, so I plan to run this one until Thursday morning, or until we produce something > 1.10 - whichever comes first.

fed up by not finding anything worthy of mention in the 50M ( I poked and hopped around like a running rabbit), I went to the other extreme : the low -low leading coeficient

the skew mightbe a bit high but it is below 10M

Thanks for all the work everyone has put in. I ran a test case the old fashion way on a GTX 460 just to see what results would pop out.

Code:

./msieve -g 0 -np 9000000,9010000

It sounds like Curtis (and I have no idea what I am talking about in this thread) has the ideal situation figured out.

Lionel will grab the best poly(s) and take it from here near the end of the week.

Day 2 produced a 1.06 and a 1.02 for me.

Getting closer...

The 1.06 has size norm 1.134 e-15 and alpha -8.45.
