I used msieve to find a polynomial for a c175.

msieve can’t sieve - GGNFS must be used for sieving

Yes. There is some randomness as to what is produced during polynomial searching as I understand it. Glad you got that part running.

It means increase one or the other or both values. Low norms are tight, higher norms are loose.



Seems low but not terribly so. I’ll check my records.

You just move the decimal point and adjust the exponent.

And remember you can round these to one or two significant digits if you wish, i.e. for...

No problem. Just keep in mind that “stock” msieve-GPU becomes less efficient as GNFS difficulty gets higher. I don’t really use it above 185-190. Then I go to CADO. But as I said in my previous post,...

In test sieving I first ran this as a 31-bit job and the yield was great. Would have been a perfectly fine way to sieve this job. But the upper end for 14d is 165-170, a 15e_small at lpba/r of 30 is...
