If I were working around a GPU as you are, I'd do up to T30 on CPU before getting a GPU involved at all.
1e6 for T35 is good.
I'd use 8e6 for T40, or I'd stick with 6e6 but send "-k 2" to GMP-ECM...

I agree that a clear and accurate measure of "enough poly select effort" is difficult. So, rather than aim for a specific amount of effort, forum members who do team poly select efforts shoot for a...

If you're looking into any study of saving time vis-a-vis ECM, I suggest you try:
1. skip the 1e6 curves
2. Do 400 @3e6 to cover the T35 and a bit of T40
3. Do 850 @8e6 for the rest of a T40.

How do you translate "a couple A40-months" from post #4 into a percentage of total effort? I'm serious here- I don't know just how fast an A40 is.

More generally, how does one convert GPU time to...

I can get 13*2^934-1 test-sieved. I was running part of a second T60 on it, but it's ECMed enough.
I'll post the job in a day or so.

Try B1 of like 1e5 to test program function. Work your way up to see where your card's memory limit is. I'd expect 5e8 to work on most cards, 1e9 is a "probably". Is stage 2 still run on CPU? The...

Try smaller bounds for B1 and/or a smaller input.

Or, tell us what input number (in digits or an expression) and B1/B2 you're using- you may be asking the program to do something well outside the...

I believe Ed's plan is to use cado sopt *instead* of msieve -nps. That is, run -np1, take that output and convert to CADO format, sopt, then back to msieve for -npr.

If I were going this route, I think I'd want to feed CADO sopt thousands of hits but not tens of thousands. The stage1 norm is still a useful filter to keep only the best GPU stage 1 hits.

Might this be useful as some sort of patch for GGNFS? Then again, is anyone conversant-enough in the code to try changing the current cofactor-splitting routine for this one?
