Weird; two digits easier than the C165 from a few posts ago, with the same params, yet needed 10M more raw relations, more unique relations, and took the same amount of time as a poly that scored 20%+ worse.

Edit: Msieve runs filtering to test for a matrix success and then waits a short time and tests again. Last fiddled with by EdH on 20220614 at 15:29

No, I think your way is actually more accurate, since it measures when a matrix can be built of a certain density rather than using userset guesses for number of relations to find.

Presumably strategy 2 was removed because of the occasional CADO filtering crashes. But with your script setup that shouldn't be an issue, as long as CADO filtering doesn't run until msieve can build a matrix. Apart from increasing qmin, the other thing to try for small c17x would be raising lpb1 to 32, and correspondingly mfb1 to 92. Last fiddled with by charybdis on 20220818 at 14:07

Thanks! I've been trying to adjust rels_wanted to make sure it exceeds Msieve matrix build relations needed, so I'll stick with strategy 2. Part of this is so the CADO filtering isn't fighting for resources while Msieve filtering is testing for a matrix. I'll adjust qmin to 15M, and raise lpb1 and mfb1 for my next c17x run, whenever I do another one.
I do run CADO filtering briefly at the end to gather the data for this thread. At that point, if it crashes, it doesn't bother my scripts, but I might miss some of the values in these posts. I can look at that later if it does occur.

If you have some specific sizes you'd be interested in, let me know and I'll post them.

Comparing with earlier in the thread, it looks to me like 3LP is slower at c160.

Here's a c165:

It seems to be a bit longer than a c163, as expected. You think I should increase qmin some more and/or take mfb1 down a bit?
