That's me. And yes, it's pretty much negligible given how long it takes to do a PRP.

EDIT: Just did a quick test. ms/iter are about 1% lower without mfaktc.

No, no. Factoring is all I do. I do a couple of PRPs, but most my work nowdays is just GPU factoring for GPU72.

Actually, never mind. That was when I tested by putting the assigned exponent into worktodo, which does a P-1 on it simultaneously?

On GeForce GTX 970 getting worse results. 12.3 ms/iter when running one instance. When running 2 I get 28.6 average. That's about 16% worse throughput.

Clean way of closing gpuowl?
