[QUOTE=RichD;459946]I haven't tried my attempt at something off the 15e queue but C212_142_108 (14e) is similar size and is ready for post-processing. It might be a touch over-sieved but I don't know for sure since I have only done one 32-bit job - which did fit into 14GB.[/QUOTE]

Oops, didn't realize that (Est pending rels == 0) != finished. I see the one I mentioned is only 7% pushed.

I guess I'll reserve C212_142_108, thanks.

I've done a few 14e/32 jobs and they worked with 16 Gb. Shouldn't be a problem for you Dubslow.

I requsted too small a Q-range, so I added 10M relations sieved locally for a total of 329M raw relations, which failed at TD 118 but built an 11.0M matrix at TD 110:

C191_3408_1668 is now in LA.
[code]
linear algebra completed 117605 of 28957954 dimensions (0.4%, ETA 1149h51m)
[/code]

So it should finish in late July.


Also, can a few more 10M rels be added to 144^91+91^144? 450M is not terribly undersieved but seems low for a SNFS 285.

RichD 2017-06-04 21:46

I'll take C195_148_98 next.

Thank you for joining me at the long-duration processing party :)
