I also haven't seen this error, and I have no ideas.

I can tell you CADO has no randomness in its procedure- so if you've seen this outcome twice, restarting with the same params is extremely...

I've been testing 3LP with much lower mfb's than usually used- say, 90 and 102 for 35/36LP job. I don't see nearly the speed hit that e.g. 103/105 would be, and I get quite a bit better yield. I...

The one big trick remaining to extend nfs@home's reach is to use 3 large primes on both sides. A 50% yield improvement would add a few digits of range, making high 220s or low 230s in reach. It may...

Pretty sure the matrix won't fit in 24GB; for reference, the C207 we team-sieved in 2019 had a 72M matrix. This is why Greg should have first crack at it!

Looking at post #2315 for test-sieve params, I think you'll find better results with the smaller lim on the 3LP side: switch the 190M and 260M. If you like, I can explore this myself.

Is there...

As I return to testing R36, I note that my sieve file is CPU-sieved, to a depth of roughly 2e14. With ~30 k's, is this a candidate to have sieved by yoyo? My sieve file is 425k-2M base 36 (shows as...

1 out of 16 for a trebling of n-range seems notably low. Low enough to make sure there wasn't a mistake somewhere?

R327 is complete to 750k. Each of the 3 k's was on its own thread on an old Sandy Bridge; I'll recombine at 760k and run multi-threaded in the future so all k's are at the same exponent size.

Enlarging the lambda *on the sieve side* beyond this 0.05 "extra" is indeed useful, because GGNFS reduces the lim on the sieve side to {start of Q range -1}. So, if you have sieve-side lim of 60M...
