ExaModels is currently one of the fastest optimization modelers, and can evaluate (sparse) derivatives in parallel on various GPUs

The winter-school on numerical methods for nonsmooth optimal control is over. It has been a great pleasure to welcome Armin Nurkanovic at Mines Paris for a week!

For CPU versus GPU, our main message is that you don't have to use an expensive GPU: I can get reasonable speed-up on the GPU I have on my laptop.

Good question. We did some benchmarks a while ago, we found out it's non-trivial to estimate the energy usage on the CPU. As such we just made a benchmark comparing our new method (HyKKT) versus our previous one (Biegler). Solving one OPF problem amounts to at most 500J using the new method.
