56M relations, ETA is now late Wednesday. Surely that will lengthen when Ed's farm naps, but that's impressive for a day's work!

Q is approaching 47M, so yield is 3.3 so far.

Pretty cool to see what we can do in a week, even without nfs@home!

I added a couple Sandy Bridge Linux systems as "localhost" today.

Cownoise scores this as 2.023e-14. I tried spinning with EdH's script but didn't get an improvement.

Try EdH's script on a scaled poly:

# size 1.581e-18, alpha -7.281, combined = 2.372e-14 rroots = 3

Maybe the script will improve it even more.

Too late for use in this GNFS job, but an impressive new high score for a c191. And it could improve even further with the script if someone wants run it.

Max's magic beats the CADO group's score for RSA-190, on a C191.
Nice find!

It only took us three years to shave a digit off then! :-)

You could fiddle with some values for -bkthresh1. I have seen this reduce memory usage a lot in large memory cases. Reducing the memory too much can slow it down.

Thanks, but as far as I can tell, all the machines I'm connecting are working fine this time. I will try to keep your note in mind for the future.

It came up with some different coefficients, but no improvement for score:
