I have NFS and ECM running against the 2858:c120. It should be finished by tonight, if no one else goes ahead and factors it.

The machine should automatically update the db, so I might not post anything here in a timely manner, if I haven't noticed the completion.

EdH 2012-01-13 01:49

It traded for a c129. Working it...

Doing NFS on the c129.

[QUOTE=akruppa;286180]Doing NFS on the c129.[/QUOTE]
I'm about 2/3 done. I should have factors overnight or in the morning...

EdH 2012-01-14 04:36

Actually, I underestimated - it's already filtering...

Sorry, I wasn't more clear earlier when I wrote, "Working it..."

edit: Hmm, had some overlap between a couple machines and it looks like a huge percentage of duplicates.:sad: Might be back to overnight. Maybe you can get yours done before mine...

I put 7600 ECM curves @ 43M into yoyo@home queue and send then with high priority.
