7489_71m1 can be moved to post-processing. With TD 120, it build a matrix of size 27M.
Do we have a guide on how to select the first TD value that should be tried in dependecy of the relation count?

It depends.

Seriously it’s roughly a function of siever used (14d, 15e, 16e_small) and lpb (31,32,33). I personally use historical data and experience. I would use TD=110 for a 31-bit job on 14, and go with TD of 130+ for the biggest jobs. IIRC the biggest TD I can remember ever seeing is 140.

In this case I think TD of 126 or 128 would probably build a matrix. But higher TD does not guarantee a huge reduction in solve time - sometimes it’s just a few hours to maybe half a day savings.

The above is what has worked for me, obviously not the optimal solution backed with rigorous analysis!

ETA: the number of rels is obviously a factor but I tend to use the same number of rels for a given lpb value.

C213_146_132 is done. I used this as a test run on the NCSA Delta cluster on 4x A100 gpus. The 26M matrix took 3.5 hours to solve.

I use 120 for all but the smallest jobs (and I don't post-process the small jobs on e-small or 14 anymore). I'm not convinced 124 or 130 results in a faster-to-solve matrix anyway, and if I get a matrix of a size I expect at 120 I just solve it.

It's a useful experiment to take a job from 15e or a big e-small job and filter with TD 120 then start the matrix step and note ETA, then repeat at 128 or 130. I doubt the ETA will change much, like on the order of 5% of expected time. So, i'd rather not filter multiple times... but I may be mistaken about the time savings.
