Strong scaling on Summit

Dear PyFR developers,

My colleague and I would like to setup two separate projects with PyFR:

1 external flow over a detailed car geometry,
2 internal incompressible flow through pipe bends with strong buoyancy.

I have asked about the latter before, although never managed to run appropriate
tests since then. We now have some preliminary tests on our medium size
internal P9+6xV100 cluster and we see perfect scaling. Currently, we are
evaluating whether our applications could benefit from Summit.

My question to you is whether any Summit results have been published or
presented in some format already? I would assume you have run benchmarks there.
We want to avoid work repetition if possible and are interested if there are
any lessons to be learnt for such installations.

Please let us know.

Best wishes,
Robert

Hi Robert,

Freddie,

Thanks for this. This is precisely what I was looking for. I've been also
testing CUDA Aware MPI but on simpler benchmarks, but internally rather than on
Summit.

Best wishes,
Robert
