[QUOTE=Batalov;296194] EDIT: musing about Jayson's correct message below (a primitive explanation) Norm makes this one faster, but less productive per the work range (due to alpha), so the range does need correction. Oh, wait, you shrunk it /I would have expected it to need be extended/. Anyway, Ben will adjust as needed.

Good call B[sup]2[/sup]! Too small for RSALS and even if they did it, the job would be first in queue for a day.[/QUOTE]

Yeah, I didn't want to wait for or bother RSALS with this middling number. Sieving 5M-25M yielded 32M+ relations, which was plenty (24-25 was done with 14e on my workstation, since that's what yafu decided to use, the rest with 13e on the mini-cluster).

Msieve will be done with it in another hour and a half.

Here we go again.

Yep! Now on i3014. ECMing the C117...

I've started NFS, but anyone is welcome to beat me to a factor.

How many cores do I need to beat you ;)

yoyo[/QUOTE]

That's the spirit!

I'm running on 6, but even with the head start you'd probably only need 8-12 cores or so :smile:.

bsquared 2012-04-12 18:48

Done, now on i3015. I'm stepping out for now.

akruppa 2012-04-12 21:01

Doing NFS on c111. Stopped, c111 got factored somehow.

Dubslow 2012-04-12 23:31

I guess somebody ECMd it. The C139 is gonna be a tough cookie.

When it's done with the 3M I'll kill it, then we'll run standard ECM... and restart the cycle.

Better a c139 than a bad p139 :-)

Dubslow 2012-04-13 04:17

I called it quits at 1600@3M; started 1000@12M, and somebody should probably run at least a few hundred north of 40M. (And of course, a volunteer to start nfs.)
