As a data point from the "real world", the Australian Supercomputing
Facility currently offers Open MPI but not MPICH2 [1]. Mind you the
clusters are just x86_64 so no arcane architecture.
They will install new software if users request and justify the need, so
they might potentially build MPICH2 if someone asked, though I imagine
they'd first strongly encourage the user to try Open MPI first.
