Seems to have hit the sweet spot for me. Used a lot of memory but left plenty for the rest, and took forever too on this now-ancient Sandy Bridge.

It looks like C176_104281_47 is unclaimed, so I'll take it.

I just started running msieve on C193_251xx527_13. All I am getting is a running list of error -11 reading each relation. I think the poly and the fb files are not in sync based on prior experience.

In the poly file, m is positive while in the fb file, R0 is negative (the numbers are the same). Is this incorrect, or is there another problem that I should look for?

I would be appreciative if someone with more knowledge would take a look and advise. Thanks!

Remove the second set of R0/R1 lines from the .fb file. i.e, the
R1 1
R0 <negative big number>
and try again.

Thanks very much, Rich! That worked like a charm....

I have a 32GB server node that needs a task while I'm away from campus for the summer, so I'll reserve 135^124+124^135 (GNFS-196) from the 15e queue.

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