600 (GMP-ECM stages 1 and 2) + 64 (GPU-ECM stage 1, GMP_ECM stage 2) @ B1=3e6 on the C99, NF.
I wanted to launch only 300 CPU curves, but I screwed up on the argument to the script...

bsquared · 2012-04-11, 17:44

Sorry, I did the C99.

I'm on the C118 now (actually - C98).

bsquared · 2012-04-11, 18:00

Done. I'll disappear back into the woodwork for awhile now. There's a easy c89 waiting for someone.

Isn't that enough ECM?

For the c140, the 13e siever is faster than 14e. Here's a poly:

(If RSALS wants to sieve it with 14e, then stop at Q=15M instead)

Code:

# sieve with ggnfs lasieve4 I13e on alg side from Q=5M to 26M
# est ~29M raw relations (avg. 0.029 sec/rel C2D @ 3.4GHz)

Looks like enough ECM. Maybe
