Linear algebra reservations, progress and results - Page 167

I did 13*2^792-1 last week, an easy (poly score 4.966e-13) 14e/32 job. 363M raw relations used 6024MB in filtering to produce a 9.2M matrix @ density 125, which needed 4450MB during LA phase (numbers are according to msieve log, not actual linux measurements).

I think filtering can use less memory if need be, so I wager you'll be under 7GB with a 400M-raw-relation dataset and resulting matrix.

I would like to reserve C171_829332_3638 for post-processing. I will need access to the relations once sieving completes. Thanks!

I'll take C204_19xx41_11 next from the 14e queue.

swellman · 2017-03-13, 23:50

I'll take C172_327668647153_19 once sieving is complete.

fivemack · 2017-03-14, 09:13

I'll take C201_142_80 (ETA morning of 20 March)
