2,1084+ seems to be nearing completion. Perhaps machines that had been working
on it have switched over to 14e and 15f before the next large one starts up??

There’s also this where Carlos calls for work to be added to 16e. This seems to gel with Bob’s observation.

Regardless I say enjoy it while it lasts!

Skew was chosen by cownoise, rather than math; the 6th root of 4/13 is 0.822, which is the skew I used for test-sieving (before thinking to try cownoise for skew just this morning).
Q from 10-240M is sufficient for ~590M raw relations on this 32/33 hybrid:

Code:

q-ranges of 500 were tested, on -r side
#Q=20M	2730 rels, 0.134 sec/rel	
#Q=40M	1772 rels, 0.173 sec/rel	
#Q=60M	1664 rels, 0.189 sec/rel	
#Q=100M	1390 rels, 0.218 sec/rel	
#Q=120M	1352 rels, 0.230 sec/rel	
#Q=140M	1413 rels, 0.234 sec/rel	
#Q=160M	1194 rels, 0.259 sec/rel	
#Q=180M	827 rels, 0.249 sec/rel		
#Q=200M	1379 rels, 0.254 sec/rel	
#Q=220M	793 rels, 0.304 sec/rel		
#Q=240M	995 rels, 0.282 sec/rel

I'd like to handle the matrix.

2,1084+ seems to have "ramped up" again. I suspect that there was a hiccup
of some kind in the server with respect to the 16e queue.

I'd like to handle the matrix.

Looks like I somehow skipped Q=80M, so my estimate of Q-range is 20M too high. If it's possible to edit the job in the queue, Q to 220M should be sufficient!

The server dried a few days ago but Greg in the meantime extended the sieve range for it.

I wonder why the yield on this number is half from my testing. I just realized I used 15e during test sieving. I should have realized something was up because the relations came so quickly for this size number. Probably need to go to at least Q=40M, or more.

Someone kicked Q up to 40M, but I’ve kicked it again to 45M.
