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...

Yes. 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,...

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.



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 a substantial list. 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...

Check out Kamada’s site. List of Near Redigit SNFS and GNFS jobs waiting to be run. Some need ECM, others NFS.

Or PM me if you’d rather fish in deeper waters.

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,...

@storm5510 -

You need one file in you msieve directory to generate a polynomial:

worktodo.ini

The worktodo.ini file contains only the number being factored in decimal notation.

You can then generate a...

And you should include -nc3 in the restart invocation line if you want msieve to immediately carry on to the full factorization, e.g.


./msieve -v -ncr -nc3 -t 4


Or whatever number of...
