560_3_560m1 can be moved to post processing; it build a matrix of size 21.6M at TD=130. Since I was asked to report on the amount of bad relations, here is what msieve told me:

Code:

skipped 29842 relations with b > 2^32
skipped 251 relations with composite factors

Taking 11m10_263.

10p3_262 is factored.

Code:

f51_169m1 has built a matrix, with target_density=130. LA should finish in about 189 hours.

I seem to have underestimated the yield, so it's very oversieved (536,217,998 relations). -nc1 took 11:34:17 which is longer than I expected, is that likely to be caused by the oversieving?

Yes. More relations = more time spent in duplicate, singleton and clique removal.

13*2^927-1 is complete:

Code:

p73 factor: 2603898733805291076674019792028353809528241831869475176394735706195163081

645M unique relations were enough for this 33LP job to build a 35.0M matrix at TD 116. This took me nearly 18 days to solve on an idle 5950X, this CPU's first job.

5231_73m1 has built a matrix of size 32.9M at TD 110 (114 failed). ETA: 320 h.

kruoli · 2022-07-01, 17:25

About one or two hours later, I got submatrix is not invertible. Does that mean I need more relations or will I be able to proceed by lowering TD further (or something else entirely)?

Other threads about this problem suggested insufficient memory, but this is definitely no issue here.

It usually means there was a hardware error. If you restart, does it consistently fail in the same location?
