Distributed standalone driver benchmarks on bencher

pitch-2b9d64 · in Runtime improvements

  • No No-gos section. The pitch template asks for one — it is what keeps the appetite honest.

Problem

There is no continuous benchmarking for the full standalone driver distributed, so nobody can see whether the driver as a whole is getting faster.

Appetite

Two weeks at most. The minimum is the full standalone driver with one experiment; separate initial conditions, more experiments and more timesteps are bonus.

Solution

Follow the existing bencher benchmarks, which should be straightforward. The MPI setup needs verifying for bencher runs, in particular that results are uploaded by one rank only.

Rabbit holes

Too many variations of the benchmark. One is better than none.
