VictordeHolland · 2018-05-20, 21:48

Not even at at TD=70 ?

swellman · 2018-05-20, 22:52

No, msieve is failing before it even attempts to build the matrix using TD. Or so it appears.

Dubslow · 2018-05-21, 04:14

Too few cycles is affected by TD. It's pretty close to building a matrix. 20-40 TD lower should definitely build, though maybe as few as 5 lower will build.

swellman · 2018-05-21, 10:34

My error, I did manage to build a matrix at TD 70 overnight, ETA 1360 hrs. Now attempting at TD 100.

TD=100 could not build a matrix. Trying 90.

C241_13829_59 is going to take some time:

I have put on 50MQ of extra sieving, which I suspect will finish in well under 1360 hours and make your life easier.

Thank you! For the record, TD=90 built a matrix with an ETA of 1265 hrs.
