It's a Core2-era 8 cpu node, so it won't be finished quickly!

At the rate that queue is moving that number may not be ready for post-processing until the end of summer.

I hope that's not true! I leave 10 Jul for a lengthy vacation, and won't be back to my office (and the server) until mid to late Aug.
130^121 should be done in 7-9 days, a day or three to top off the GNFS-195, and 2 weeks for the GNFS 196 should make it just in time.

But there is a loner lurking in the queue.

VBCurtis - It would be a terrible waste of assets to have your 32Gb machine sitting idle all summer because of scheduling issues. I have not yet started on 144^91+91^144, which is ready for immediate start. Do you want to take it? It will be a challenging job, one that may require 32Gb. Or take 148^83 + 83^148 if you prefer but it won't be ready for sieving for some weeks.

My own 32Gb box is still working the GNFS(190.47) job and won't be done until late July. I yield whichever numbers you wish to take. Have at 'em!

Thanks, Sean. I'll take 144_91+91^144, then. I should be able to get it started this week.

Outstanding. We can play the reservations by ear - if 144_91+91^144 finishes before you leave town (which is no sure thing), feel free to grab the biggest remaining sieved job. I'm around all summer so I have more flexibility.

Log is slightly inaccessible (I am using an iPad and attaching a file is hard) will update Sunday by which point C213_142_74 should also be done
