Correct poly. I used 268/400M for lim's, and 33LP 64/95 for mfb's.
Basically, I chose params as if ggnfs was all we were using for the job, also the ones we used for the job that we just sieved in...

Update: Q=43.1M, 114.4M relations. Yield average almost exactly 5.0, down a bit from the 20-25MQ range.

Forecast is 350M or so relations by Q=100M (80MQ * 4.x yield).
That leaves ~650M for...

My guess is the timeout is for poly select workunits, because they are prone to get "stuck" and because one late WU can delay an entire factorization by quite a bit; while a missing WU on sieving...

Next time you think your formula found a prime, check it yourself- the software is found at mersenne.org. That way you won't have to share credit with anyone else!

after 20 hours, we have done almost 2.5MQ, 13.9M raw relations. Yield is just under 6.

I have seen no errors on the server, no workunits timing out. There were a couple of reissued WUs because I...

Yep! My records suggest it's large-prime-size choice and siever area, but lim's might go into the calculation of Bf and Bg too.
