2:50 h on a GeForce RTX 2060 SUPER for msieve stage1, about a minute for CADO sizeopt (one CPU core) and 15 minutes msieve rootsieve (one CPU core).

Do you still have a list of polys before and after CADO sizeopt? Could you please post both here or send them via PM? I would really appreciate it.

Could you please re-run this poly from *.fb file in msieve, firejuggler?
cownoise hangs (happens sometimes) and my msieve shows:

Default R337/c202

I tested the exceptionally good files.
The cpu-times are close to each other.
The poly-file from post 1931 (Gimarel/Max: skew: 50335474.00; size 8.799e-20; alpha -8.773, combined = 3.886e-15 ...)
clearly gives the most yields/1q.

parms: 16e; .lim ~ 450M; q-range: 50M - 425M; lpb. 33/33
target: 1050M r.rels; ~ 740M unique rels; matrix 45M - 49M;
Many thanks for the valuable preparatory work
Kurt

Greetings,

Any help that folks can provide in finding a poly for the C175 of of Aliquot sequence 829332 i3694 would be greatly appreciated. The composite has been ecm'ed to t55.

Code:
9536454284838131188510297375465325383144598450008668632355935685754692107419202674411506591342057862756227100567184249373517764331520778025660438418594966383559123819525015791
I am running a CPU poly search on this number for coefficients up to 1,500 using msieve through YAFU, and my intention is to use NFS@Home for sieving once a suitable poly is found.

Thanks very much!

Rich
