MPIR_CVAR_PMI_VERSION=1 ./a.out
[0] Hello, I am 0 of 1 tasks.
[1] Hello, I am 0 of 1 tasks.
still the same. I was not sure whether that option is for mpiexec or the
mpi library, so I set it twice just to be sure.

> Hm, there is a PMIx dependency that is presumably coming from the MPICH library. MPICH's mpiexec is not compatible with an external PMIx, so I suspect that is the issue. Can you try setting MPIR_CVAR_PMI_VERSION=1 and see if that works?
