GNFS might be faster, but I would not have time to search for a .poly before the BOINC pentathlon starts. And it might take more CPU time to find that it would save.

Sieve on 15e_small from 34M to 144M on the rational side.

Test sieving 10k ranges:
Code:
 34M 23804
 84M 19767
134M 17051
184M 15337
The first range test sieved is actually the 10k just below 34M, so I can add the relations in it to those downloaded.

I'll do the LA.

QUEUED AS 13_2_882m

13*2^882-1 is ready for 15e:
Code:

Test-sieving 1kQ blocks indicates Q from 25-200M should be sufficient for ~430M raw relations:
Code:
#Q=20M	3280 rels, 0.290 sec/rel
#Q=50M	3071 rels, 0.321 sec/rel
#Q=80M	2425 rels, 0.308 sec/rel
#Q=110M 2714 rels, 0.402 sec/rel
#Q=140M 2344 rels, 0.433 sec/rel
#Q=170M 1727 rels, 0.473 sec/rel
#Q=200M 2188 rels, 0.481 sec/rel
I would like to handle the matrix.
