Yes, this is what I'm doing. I just wasn't sure if it would be enough with tests_saved=1 and (relatively) small RAM, given that the server is currently still handing out tests_saved=2.

Do you have a similar opinion about petrw1's sub-2,000 project?

I don't see how tying P-1 bounds to how much P-1 is being done is supposed to improve GIMPS throughput overall.

Doesn't the GEC make this a non-issue? I wouldn't be doing direct LL DC, so a memory error would only lose a few million iterations (at most), not the whole run.
