Reserving C215_121_81 and 90007_248.

RichD · 2016-05-31, 20:37

I'll take 3511_71_minus1 next.

swellman · 2016-06-01, 15:23

I'll take C173_139_59 if it is available.

C190 from HP2 has, after approximately a month, completed and factors as:

Code:

p63 factor: 146667907054527619947831591866982064387388548030916606859838061
p128 factor: 16798062034160540136421895656299799399411001573412461266587556236179140564237600812370540515819101931523107481109190334998517397
elapsed time 15:25:16

The factor was found on the 5th dependency.

Density of the matrix was 110 (120 didn't build), and matrix was 34,089,340 x 34,089,518. Just over 22GB of RAM was used during the linear algebra phase. I don't have the exact wall time of the LA phase due to a move and some other stoppages, but it was approximately 850 hours or so on 8 threads of an i7-4930K.

I went to put the factors into FactorDB, and the database is, naturally, down for a bit. Regardless, thanks to NFS@Home for running this number.

Had to drop down to TD=112.
188 hours remaining in LA.

I'll take C215_134_74 next.

I am putting it on a box that has been spastic lately. It may take a little longer than expected.

I'm beginning to think it may be a thermal issue or loose connections. Once I get through this job I'll break the box down and blow it out (and fasten it back up).
