[b]QUEUED AS 13_2_853_m1 [/b] 13*2^853-1 is ready for SNFS on 14e:

Test-sieving indicates Q range from 15-220M should yield ~650M relations:
[code]Q=20M 0.061 sec/rel, 4806 rels
Q=40M 0.067 sec/rel, 4119 rels
Q=60M 0.075 sec/rel, 3542 rels
Q=80M 0.080 sec/rel, 3236 rels
Q=110M 0.089 sec/rel, 3501 rels
Q=140M 0.100 sec/rel, 3101 rels
Q=170M 0.107 sec/rel, 2287 rels[/code]

Alternately, 32/64 on the rational side and 33/66 alg side should yield 510M relations from Q=15-240M; the expected sieve time is marginally longer, but this saves a bit of disk space and server bandwidth.
I'll handle the matrix, please.

C146_M17_k41 from the kosta project is ready for SNFS on 14e. Straightforward factorization job for someone weary of month long efforts. I don't have the bandwidth to take it right now.

Test sieving on the -r side with Q in blocks of 10K:

Q=10M 23266
Q=18M 22066
Q=25M 23229
Q=32M 21362
Q=40M 20389
[/code]
Suggesting a sieving range for Q of 10M-38M with a target number of relations = 60M. This many relations may be a touch high for a 29-bit run, but not overly so.

I'll do it swellman.

Just to warn that C173_542xx041_3 needs more relations since it can't produce a matrix with td set to 70. Check msieve log attached.

debrouxl 2018-06-27 14:20

Alright, I've just increased the upper end of the range from 150M to 164M.

[QUOTE=debrouxl;490703]Alright, I've just increased the upper end of the range from 150M to 164M.[/QUOTE]


Please divide by 10. I’m seing set to 1640M.

debrouxl 2018-06-27 14:26

Oops. And sure enough, the WU generation job ran in the meantime, so there are now WUs for a very large range of q values :'(

Protection, or at least warning, against a likely extra zero was on the wish list for the crunching management page rework, but nobody had and has time to do that.

[QUOTE=pinhodecarlos;488828]By looking at FreeDC stats the majority of the 14e/15e wus are done by the gridcoin pools and Syracuse University, which I think they have selected all types of wu's on the preferences page. If the 14e dries they will crunch 15e but I suppose Syracuse University has a few cores only dedicated to 14e but only Greg can help us there.


To clear my point, let the 14e queue dry and the long 15e queue will be picked up with 30k wu's/day.[/QUOTE]


Picking up an old message by posting an interesting stats. By letting 16e queue dry (I've stopped chasing Greg) it's clear the majority of the clients can run and process the 15e wus at a rate of 90k-100k per day. There was a peak of 120k when some friends were running Formula Boinc.

Test sieving on the -a side with Q in blocks of 10k:
[code]
Q=30M 27964
Q=60M 32007
Q=100M 32019
Q=150M 32243
Q=200M 27700
Q=250M 26018
[/code]
Which suggests a sieving range of 40-190M with a target number of relations = 470M.
