You're funny, finish before I leave town!
A 26.3M matrix has ETA of 72 days, roughly 1 Sep.
Lots of duplicate relations, only 373M unique.

I did say it was no sure thing!

There's plenty of other challenging jobs in the 15e queue, if you have interest and assets in Sep. Hope you have a fun vacation.

If 148^83+83^148 can get another ~60-70MQ scheduled to get raw rels over 700M, I can get the LA started before I leave. It's a 4-node Dell C6100, for which MadPoo sent me his drawer of server DDR2 4GB sticks; two nodes have 32gb and two have 24gb, so I can run a second LA job over summer.

I usually use it for my personal NFS jobs, but I've been sending half of those to the 14e queue; it's only fair I take care of some LA as thanks to MadPoo for the memory and thanks to NFS@home for sieving "my" work.

~78 hrs on 5 threads of a 6-core i7 to solve an 8.5M matrix at TD 120 (128 failed to build).

Sounds good to me. You getting 148^83+83^148 into LA successfully before leaving town seems a realistic scenario. I'll step back and wait for everything to settle out before I start another 15e job in order to give you flexibility.

About 12,000 consecutive bad relations were removed from the log for size.

I'll take C164_12400411646533_17 if no one else has claimed it? I'm not sure the 14e page has been updated in a while (at least my previous job is still listed there as incomplete).

Going back a few pages, I don't think anyone's claimed C207_127_103 have they? I'll start downloading, please alert me if anyone's started it.
