## Reference timings

These benchmarks were run during the pilot phase of the LUMI-G supercomputer (December 2022), under
git commit d8f36242127b9a828f127550ecd9613eefb3f1cc. All calculations were run with 8 GPUs, 16 MPI

Thanks a lot for adding these benchmarks Augustin!

I'm a bit confused by the eight GPUs because AFAIK LUMI-G has only four GPUs per node.

Mi250 is 2 GCDs, so at the end Linux sees 8 GPUs in total
