May I have another 15-20M relations? Density 128 does not build, and density 124 yields a ~32M matrix.
L2995B is GNFS188 and has 23M matrix; I hope I can do better than 31M for GNFS191!

Err, I'm already running L5355A. Sorry, something has clearly got confused. ETA is 16th August.

fivemack · 2018-07-28, 11:32

ETA for C197_4788_12515 is 6 September, at which point I will be in Canberra so it may take a little while for the log to get onto pastebin.

Sorry about the delay; the water-cooling failed on my i9-7940X machine, and running 14 cores of linear algebra in the middle of a heatwave with a hot water bottle attached to the CPU works poorly. I've substituted a large Noctua heat sink with fan, and temperatures are much happier.

swellman · 2018-07-28, 17:46

One of my boxes did not survive a recent heat wave combined with some electrical work at the house. (The second may have been coincidence as the computer was powered off.) Regardless of the cause, I’m down a machine with a job that was over 80% complete. Such is life.

As such, I must restart the “C253_131_98b 131^98+98^131 C253 cofactor second attempt” job of 15e on another machine when one becomes available in a week or so.

At least there is a demonstrable need for a new high speed computer. SWMBO surely cannot object.

swellman · 2018-07-29, 12:44

Can someone add more relations to Fibonacci(2247)? It’s still sieving but will come in about 400M. Thank you.

TD=136 produced a 20.83M matrix. About 16 days on 6 threads of a 6-core 5820.

L2785B Failed with td=115, giving a shot with 100. Let’s see what comes up!
