elapsed time 01:01:19

The matrix was paused for many hours over the days I took to complete this, being a personal computer; the elapsed time is *not* representative of the computing required. I really should remember to time these things. The log will show me forgetting the correct options to use. Fortunately, no computations needed to be rerun due to that.

Releasing C192_124_97 since it is too large for my laptop.

Hi guys, it's been a long time... I'll run the post-processing of 126^125+125^126,
nothing like an SNFS(268) to put me back on track, can you reserve it for me please?

fivemack: OK, reserved. Please say if you want more sieving done, I think it's a bit marginal at present. Also could you PM me your actual name?

Carlos - I will attempt to run this job. According to the log file you posted it made it into LA - why did you abort the factorization? 3 weeks ETA is not uncommon for a 32-bit job, at least with my hardware (laptop). Just curious.

I've aborted due to its high memory demand and second for me 20 days is a lot on this laptop.
