I used msieve to find a polynomial for a c175. msieve can’t sieve - GGNFS must be used for sieving - one uses msieve to find a GNFS polynomial (or build your own in the case of SNFS) - sieve...

There is some randomness as to what is produced during polynomial searching as I understand it. Glad you got that part running. Stage 2 (that’s Step 7 in my example) doesn’t use the GPU,...

Low norms are tight, higher norms are loose. Seems low but not terribly so. I’ll check my records. I think so. Linux drive me crazy...

In Windows it’s a double quote symbol “ but I’m not sure if it’s single or double in Linux. But you must include -s output at the end of the invocation line. This will create a file called...

You just move the decimal point and adjust the exponent. 1826e+16 = 1.826e+19 648e+13 = 6.48e+15 And remember you can round these to one or two significant digits if you wish, i.e. for...

It is also active with a good bit of turnover - be aware of existing reservations, don’t poach, and be sure to reserve anything you choose to work on including ECM. Work an...

List of Near Redigit SNFS and GNFS jobs waiting to be run. Some need ECM, others NFS. https://stdkmd.net/nrr/wanted.htm Or PM me if you’d rather fish in deeper waters.

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,...
