Greg has sent me login details to download relations. :)

Reserving 13*2^905-1 and 13*2^784-1 when-ready, the numbers I submitted to the queue. Once I (re)learn how to invoke msieve independently of factmsieve to solve these matrices, I'll begin postprocessing other numbers in the 15e queue. I have a 6-core i7 with 16GB, should be sufficient for the smaller end of 15e.

Filtering (attempt):
msieve -v -s N.dat.gz -l N.log -i N.ini -nf N.fb -nc1 target_density=128
(if it fails retry with lower target_density)
LA:
msieve -v -s N.dat.gz -l N.log -i N.ini -nf N.fb -nc2
Square root:
msieve -v -s N.dat.gz -l N.log -i N.ini -nf N.fb -nc3

You can use "-nc2 -nc3" to perform both LA and sqrt in one go,
you need a zlib enabled msieve.

Thanks - that did the trick! C192_124_97 is in LA, factors expected in mid-Jan.

My laptop cooling pad died and I don't intend to buy a new one this year therefore I need to unreserve 5+2_377. Once again I apologise. Trying my best to help the project but I'm really being unlucky.

I'll take C248_132_89 next.

70M dups. Matrix built at TD=120 (124 failed).
188 hours for a 14.5M matrix. ETA mid next week.
