Do you understand how version numbers work? If you do, you can figure out whether 1.9 and 1.10 are in the future or the past. I say this since the context of the posts escapes you entirely.

There's a strong chance it's just a lucky polynomial with better-than-avg duplication rate. I could see a small improvement in unique-to-raw ratio if this run needed a smaller Q range (i.e. much...

Actually, I assumed GMP-ECM for the runs, as it is dramatically faster than P95 for this very small (by GIMPS standards) number. You'll find that B2 is much much more than 100* B1 when using...

Note that lim of 67.5M is just barely over 2^26; ggnfs sievers take a speed hit when we jump bitlevels on lim, so the lim's should be 67000000 rather than 67500000.
This isn't a big deal at 67M, but...

mersennne.org does something similar- I run ECM with B1=80k, B2=100*B1, and every 5 curves I run earns credit of 8 standard B1=50k curves. It's not a perfect conversion, but it works well enough for...

I don't think it applies to even-smaller primes than 1e5- small primes should divide many candidates.

By the time you're sieving out a prime near 100,000, I think there are fewer than 100k...

So, one fast GPU can spend 1e54 days to have roughly a 1 in 250 chance to find a factor.

Or, you could run regular ECM with large bounds (B1=3e9 or bigger) and actually contribute non-useless work.
