Wow! A p59 at t50!!

As I was closing in on 4000 @ 43e6.

RichD 2013-08-09 18:29

c155 @ i1311
 
1000 @ 3e6 - nothing
passing through 500 @ 11e6

Edit: and -pm1 2e9

RichD 2013-08-10 06:00

2850 @ 11e6 - nothing
Passing through 50 @ 43e6

BTW, I intentionally don't complete a level incase others are working it and haven't reported their work. Backfilling can always be done at the end before starting GNFS.

RichD 2013-08-11 20:15

1300 @ 43e6 - nothing.

RichD 2013-08-13 02:06

Getting back into this one after needing all cores for an NFS job.

Passing through 800 @ 43e6
(Total of 2100 so far by me.)

VBCurtis 2013-08-13 04:18

Does the plan call for a full t50 for this one?
Rephrased: What ratio of ECM-test to digit-length is standard around here?

I don't have threads to spare for a few days, so firejuggler might have to poly-select this one too.
