Running finite element models with MSC NASTRAN, basically heavy matrix math. Matrices were NxN, N was around 10 million. This was on a server with 36 cores and a half terabyte of RAM, purchased in 2014.

Also seen Erlang workloads where you could get a bit of throughput increase with your VM scheduler scheduling more threads than your physical cores (so starting to use HT) but the latency would spike and become very unpredictable, which was a bad tradeoff for the use case.
