MPICH question

[sheevy]

I have a Docker image of my python program which calls into parallel version of meep (https://meep.readthedocs.io/en/latest/) which is compiled against the MPICH (pymeep package in conda-forge). I'd like to run it on the K8s using MPI-Operator. I see 3 possible paths:

1. Extend MPI-Operator to support MPICH
2. Recompile Parallel Meep to use OpenMPI
3. This whole things won't work either way because of shenanigans of havin MPI enabled app inside conda environemnt in docker which is not supported.

Any advice which is better? Will it even work or am I doomed and I'll hit point 3 above?

I have no idea whether it would work, but I would be happy to review a PR to support MPICH.
