Thanks a lot for all the help so far!

I read about srsieve2, but wasn't sure if it's ready yet. Maybe rogue can say if for fixed k and n in the 3M-4M range which of sr1sieve, sr2sieve or srsieve2 is fastest?

sr2sieve expects a file in format usable by LLR (-g flag from srfile), not abcd
sr2sieve accepts abcd as input, I'm currently using it.

If k is so large that you cannot build Legendre tables, then srsieve2 is probably faster. The Legendre logic fully coded and tested in srsieve2.

Sorry for the typo, that was intended to be sr1sieve not sr2sieve in the part you quoted.

You should test the 3 programs yourself to see which is faster!

I will do a comparison later, first I want to finish sieving... I'm at 5e12 now and factors are coming in considerably slower, but still at about 3 min per factor. The range 3320000 <= n <= 4100000 is down to 14550 candidates.



Somewhere I read proth20 did one test on a gtx 1660 in 6-7 minutes (forgot the specifics of the candidate). So I will continue sieving for a while.
