Thanks for the warning. I have 3 15e-sized jobs ECMed in case we were chosen; I'll get them test-sieved and posted asap.

It's nice to have hard evidence that both-sides sieving is not helpful unless our choice of siever is restricted. Thanks for posting data!

Doesn't matter whether msieve or cado does the matrix; I use matrix size as a marker for whether target_relations was set too high or too low.

Sure, I can post a draft. There hasn't been a ton of testing at that size, but Charybdis did a few jobs. I'll track down the data this weekend and get one posted to this thread.

This depends quite heavily on what size large primes are in use. 200M relations is just getting started for a 33LP job, and will still have pleasant duplication rates in the 20% range.

How does msieve ever see the raw relations count, if you run remdups first? I mean, the whole point of remdups is to feed msieve only the uniques.

You're correct about that log *if* remdups is not...

The data point not in the log file that remdups provides, and I think is useful to others / future, is uniques vs raw relations. I post that data on almost every factor report.
