There tends to be two flavors floating around. The one I usually follow is the 1/3 GNFS rule. So this number is 155/3 or about 51.67 or a full t50 plus nearly 2/5 of t55, or another 6000 @ 11e7. We are still days, if not weeks, away from poly selection time.
Passing through 1150 @ 43e6

GNFS 155 job takes 56 weeks on my computer, and a full t50 takes 9 days on the same machine.

Sorry, it takes about 4 (instead of 56) weeks, so I use (GNFS digits  6)/3 rule.

This will most likely be a team sieve.
Passing through 5240 @ 43e6 (total of 6540 @ 43e6) Switching a core to 11e7.

It's just my opinion though. Quote:
Because the 64bit siever brings 2x speedup over its 32bit counterpart, and each 6 digits added also mean 2x longer job, I think 6 is to be subtracted from the GNFS digits first. Last fiddled with by prgamma10 on 20130814 at 16:17

I understand what you doing. It looks like we are about poly ready. I'll make a request over in the Msieve thread.
Another 6285 @ 43e6  nothing Switching all to 11e7.

2500 @ 11e7  nothing.
We got a good poly thanks to firejuggler so it's time to sieve this number.
