I don't know if I ever got the sequence down to a C102 I believe I was at a C109 but the factorization may have come across one I guess. my gnfs test.n does have the number I wanted to test ( assuming it's the right one so it will add another line) but it didn't do that one. I'm unsure if I leave factMsieve.pl in there.

You also have to keep factmsieve.pl!

sorry I didn't think ( and yes I know what else is new).

One thing that will not be clear unless you've got a good grasp of the workflow is that when you start the script, it does a couple of things.....say you start thew script with perl factmsieve.pl test, here is what happens:
• Is there a file test.poly? If so, set up to sieve using that poly.
• Is there a file test.n? If so, search for a poly for a while, then start to sieve with that poly.
• If no *.n or *.poly, print USAGE info and exit.
That means that if you have a test.poly from the last run and only edit the test.n file, it will re-run the previous number....

even going up linearly ( I know likely best case scenario) time wise puts my current C109 at 18 h 21 min 36 seconds. if I did my math correct.

I'm using the "factmsieve.py"-version and 2 batches for easy-to-use (WIN):

1. "do.bat"
Code:
factMsieve.py test
2. "clear.bat"
Code:
ren test.n temp.n
del *test*.* spairs.save.gz .last* ggnfs.log
ren temp.n test.n
Step1: Using ggnfs for factoring, put the number in file "test.n" and call 'do'.

Step2: Before starting the next number, call 'clear' and all not used files are deleted. Goto Step1 next.

Be sure you got the factorization before calling 'clear' or remove the entry 'ggnfs.log' in 'clear.bat' (it contains the factors).

forgot to mention apparently over 1 million of the 12 million relation it says so far are hash collisions. though I did a virus scan so that might cause it.

That is normal. Also errors -1 and -15 happens from time to time, especially if you restart. If you have millions of them (as happened to me) then most probably you mismatched the poly or the job file. But just for a couple of them, is ok. Is normal to have 10, 20, 50 errors like that in few million relations. And hash collisions have nothing to do with the virus check.

thanks for the explanation.
