Wanted a stress tester I could throw into scripts and CI without spinning up a GUI. Most open source options skip the GPU entirely, so I wired in Metal for the GPU side.

It runs matrix ops, FFTs, and particle sims concurrently and draws live utilization bars in the terminal — one for CPU, one for GPU.

Curious if the workload mix is actually representative or if I'm missing something obvious. Also open to feedback on the Metal implementation if anyone's gone down that path.
