It's definitely warranted. Using a 4% guideline for poly select to expected sieve time, this ~120 core-year job should take ~5 core-years of poly select.

I don't know Gimarel's resources, but I...

I didn't ask for the procedure, I asked which primes you would use that slowest-possible procedure on, instead of something faster.

No, ECPP isn't a factoring algorithm. You could try wiki for a...

What sorts of primes do you prove by trial factoring?

In what context do you mean "ECPP is factoring regardless"?

Sounds like way too big a matrix for an e-small job. Maybe add 10MQ, if you haven't already moved it to post-processing?
Or, we could do some sieving locally. Let's knock off at least a week from...

Squaring the 31 is the manner in which one breaks 2^4 * 31.
Other powers of 2 would not be a driver; only the perfect number 496 = 2^4 * 31 is a driver.
