I started a run of 1956 ecm curves at 43e6 (b2 is 240490660426)

Greebley · 2009-10-07, 16:12

I just calculated that this will take about 48 hours.

Whoops, missed a digit. Make that 20 days instead of 2.

1172 curves @ B1=43e6, B2=240490660426, no factor.
Curves already reported to the DB. I have queued some more and will keep reporting them to the DB.

P+1 (3 runs) with B1=1e9, B2 = 1e14 also found no factor.

Looks like my single processor can do a bit less than 100 tries a day, so the 20 days seems fairly accurate. I will let it run until we are to the polynomial stage or it finds a factor.

I added 413 more curves at B1=43M, no factor.
I am now taking one of two CPUs from this number, hence sequence 10212, which I am working on, has hit a c124 which needs GNFS, which I don't want to do on a P4 which is NOT running 24/7. The second CPU will run more ECM curves until tomorrow in the early morning.

127 more curves @ 43e6, no factor.

4000 curves at 43M will be done tomorrow (~17hrs from now).

Done, no factor. I'll do a few curves at 110M overnight.

It survived 800 curves at 110M (B2 = 776278396540) done last night. Anyone have a complete ECM curve count? Where are we now?
