Add new benchmark: Nvidia HPCG #326

Open giordano opened 4 months ago

giordano commented 4 months ago

The Nvidia HPCG benchmark used to available only via containers, but it was open-sourced last week and it's available at https://github.com/NVIDIA/nvidia-hpcg. This works on both CPU (x86-64 and aarch64, with specific optimisations for Nvidia Grace, aka Neoverse V2) and GPU, and also mixed CPU-GPU configuration (maybe only on Grace-Hopper/Blackwell systems?).

@christophermaynard you may be interested in this.

This might be something @krishnakumarg1984 would be interested in

@krishnakumarg1984 started working on this. I added tasks in the main comment

How do we get cuSparse and cuBlas?

Those should presumably be in the cuda package? For example py-cupy claims to use those libraries

That'd be great! It wasn't clear to me when I looked at it yesterday
