Create containers for CI #86
Description
To speed up the CI, especially for GPU-enabled compilations, we can use an ad-hoc image.
Ideally, we need:
- GPU and non-GPU aware MPI (but it should be for tests once we have GPU runners)
- Different flavors of MPI implementations
- Different levels of MPI support: with and without MPI_Sessions, for example (Draft kokkos-comm initialization/finalization using
MPI_Sessions #68)
