Thanks, but to do that, I think -np1 would work better since I wouldn't need to create as many other files first. But I'd still need to look for a value (such as "using GPU" in the log. I was...

A small follow-up:

I now have the Tesla M40 24GB running and am quite pleased. But, there is room for improvement. It is throttling due to insufficient cooling. It gets to 87C and cuts its...

Reinstalled driver and CUDA in different variations and no joy. The computer says it's there, but CUDA says it isn't. I put the K20Xm back in and it sees it every time. Both are PCIEx16 v3.0.

I'm hoping to set up a machine to primarily do GPU LA with an M40 24GB card.

- Will a Core2 Duo 3.16GHz be better (or much worse) than a slower Quad core?
- - When running the GPU, is LA doing...
