C193_2340_742 linear algebra started, should be done by mid-August (31.5M matrix with density 120)

Taking 9109_61_minus1 (ETA Wednesday afternoon)

18 new factors have been reported in the last five weeks, due in part to the contribution of the sievers working for NFS@Home. They are given in the table below and have also been uploaded to the web site.

There are now 154 composites left in the tables. It's still possible that the latter will be extended this year if recent progress is maintained.

NFS@Home doesn't have any numbers scheduled.

My work has slowed down. Partially from lack of resources, partially from the numbers getting bigger.

Taking GW_11_229, should run over the weekend so ETA Monday morning (27th)

fivemack · 2015-07-23, 22:57

There may be a bit of a delay on some of the 15e jobs: I'm having the house redecorated, the decorators turned the power off at short notice, and the compute farm doesn't seem to come back up terribly well from a power outage - I should take the opportunity to replace a failing disc in the RAID1, but I can't work out where the decorators tidied away the replacement disc I'd bought :~|
