Yep- you're going up "half" a siever, so yield will go up by about 40%, and you'll need about 70% of the Q you would have needed for I=14. However, since bur's tests are showing that Q-max to Q-min...

I think in Ed's case it's that at some point CADO stopped compiling for core-2 era chips, so some of his farm uses a CADO version from before A= sievers were implemented.

May I have another 15MQ on 13_2_922m1? 600M raw relations looks a little light; I've been targeting 620-630M.

Done.

Only the first step (polynomial selection) is cuda-enabled.
If you use a version of msieve compiled for CUDA, it will automatically use the GPU for that step.

Remember, big quartics really benefit from unequal large-prime bounds. I bet this would have been faster as 31/33 (or maybe 32/33).

I suspect you misunderstand how P-1 bounds work. Just because you find one doesn't mean the previous P-1 run missed it the way that TF report says "missed factor". Can you give us an example of an...

With yield under 1.5 and that wide a Q-range, you're likely to get an unpleasant duplicate ratio. A job this size really calls for 32-bit large primes, and I imagine 3LP on one side too. I bet yield...

I like this idea best! I'm not sure 20 factors needs 10 TF levels- P-1 with 9% add'l probability does the same, and once that's done there would still be a 1/100 or 1/120 shot for each TF level. For...
