I’m a structural engineer, running nonlinear analyses of buildings. These take about 3-5 days to run on an i9-9900k. The program runs each earthquake simulation on a single core.

Man, this is just begging for parallelization.

I can make multiple instances to run multiple simulations in parallel, but matrix factorisation within the program itself is single-threaded. The stiffness matrix of these structures needs to be reformulated frequently (every time a structural element yields / gets damaged), so this is the largest time-sink, I think.

thats just a shitty program lol

I'm not disagreeing with you... Its horrible but that is the industry standard.

Honestly my biggest problem right now is that I don't even know if there's anything I can buy/upgrade to speed it up. I don't know how to determine what the bottleneck is, so to speak.
