I'm running gradual selection on a 386 million point cloud (from 82,000 cameras) and the initial "Analyzing Point Cloud" step after I select which parameter to use and before I select the gradual selection threshold is taking quite a while. It looks like it's going to be about 5-6 hours on my workstation (80% done @ 4h), and it's going to take > 8 hours on a HPC login node with slower RAM. Wondering if there's anything I can do to speed this up (headless? 1.7.x?).
On the workstation (Threadripper 3960x with 256GB 3000MHz RAM and 2x RTX 2080 Super GPUs) it appears to be using minimal CPU resources (maybe a single core, resource monitor says ~4% CPU) and it's using about 60GB of 256GB total RAM (total system usage is about 72GB).
