I believe I have a solution. Testing will be needed.
I build a serial version of esmf
that I will upload to the e3sm
anaconda channel once I've tested.
I have updated the build script to include building mpi4py with native MPI on cori
, compy
, anvil
, cooley
and grizzly
. I won't do this on rhea
or acme1
unless it is requested.

@jhkennedy, I’ve been in discussion with Min about a workaround but worth discussing between the two of us, too.

I'm following these instructions at NERSC:
https://docs.nersc.gov/programming/high-level-environments/python/mpi4py/#mpi4py-in-your-custom-conda-environment
from e3sm-unified.
I also tested on compy with:
module load gcc/4.8.5
module load mvapich2/2.3.1
The resulting environment with mpi4py
appears to work for calls to mpirun
but not to srun
. @rljacob, do you know if/under what conditions srun
works on compy
?

I haven't tested yet, but I think the system MPI and the conda installation of MPICH aren't going to play nice with one another. The esmf
package depends on mpich
and is a dependency of nco
so we're going to be in a bit of trouble. Things might work at NERSC via srun
(which uses system MPI) for mpi4py
calls and mpirun
(which will use the conda mpich
) for esmf
calls. But, given that srun
didn't work for me on compy
, we might be in trouble there.

So the solution I came up with doesn't seem to work for esmpy
(and therefore maybe not for many of our packages, thought e3sm_diags
is the only one where I'm sure). I'll explore more for the next release...
