A bit lower score, but more reasonable skew.

1.88e-014, nice. I have a small collection of 1.7e-014 -1.79e-014 if you want to testsieve them.
There is a better poly derived from firejuggler's 1.881 (with a different c5 and lower skew):

Thank you, I have unqueued the number and am trial-sieving this new polynomial.

The new polynomial has a lower yield than the 1.881e-14 one in every one of the trial sieve buckets I used, so I'm going with the 1.881e-14 one.

Default L1532 C192 request

Would anyone be willing to do some polynomial selection on the following C192

Code:
218970570796182065698377596097024384788361869332761272840394703510787597605276873474046837687885995912329231998076410885135080521826943850036783229565403944064025633738188802389499489670808641
the cofactor of L1532 Lucas(1532) ?

msieve-cuda polynomial selection has entirely stopped working for me since I went to the cuda 8 compilers and drivers, and polynomial selection on CPU is distressingly slow (though I am hammering away at F2583)

Sure thing, taking 0-2M range.

I'll start with 4-5M with msieve-GPU.

Default poly for C156 kindly request

Would anyone be willing to do poly search on that one C156 ?
With simple yafu (no CADO nor Msieve) I receive poly not better than e = 1.952e-012.

Thanks a lot in advance,

cubaq

PS. Please use format of nfs.dat.p I.E.

Sure, I'll have something for you tonight or Sat morning (USA pacific time).
Edit: 10 minutes of search turned up 2.11e-12. Definitely absolutely don't use the poly you found!
Edit2: running coeff 500k-2M, just in case someone else wants to beat my score.
