For a workstation (or extravagant home system) look at the RTX A6000. It's likely faster than a V100 for about half the price (currently ~$5k). For that matter the RTX 3090, currently ~$1.5k, will likely be faster but will be memory constrained to e_small and some e jobs.

9p8_610L has built a 13.87M matrix and LA will complete on January 5 on an i7 with 6 threads. Even though I set target density = 130, the filtering stage only achieves a density of 85. I'll just let it chug along.

That usually means it was over-sieved. Try setting filter_maxrels=255000000 or something there about.

f72_137p1 built a matrix on 24 Dec (I've been visiting relatives so couldn't report it sooner). LA should finish in about 15 hours.

Reduced max relations to 255M and matrix size reduced to 12.98M with a density of 123, but time increased from 200 to 205 hours. So I'm just going to let it run now.

If anyone wants to do LA for f43_169m1 they are welcome to. If not I'll do it once I've done f88_131p1.
