I'm having some [URL="https://pastebin.com/iJWttywi"]problems[/URL] with this. There were roughly 150M unique relations, for a 25% duplication rate. I think it's undersieved? Been a while since I've tried to discern under- from over-, I'd appreciate a second opinion from the log file above.

Definitely under-sieved. Borderline cases result in "too few cycles, matrix probably cannot build", but this fails well before that part. You need more relations.

Well I seem to recall seeing the "filtering wants x more relations" in cases of oversieved too.

Anyways, fivemack? The other similar size/bit jobs have another 50M spq beyond what this one had. (I guess that should have been my other clue :razz:)

Piling on, I think C186_134_77 in the 15e queue is also undersieved.

fivemack 2018-04-13 09:46

I queued a couple of numbers with the anticipation of putting up the Q count once I saw realistic yield figures; I missed that stage and am doing it now.

+30MQ on C220_148xx049_19
+30MQ on C186_134_77
+10MQ on C240_127_111
