Somewhere between r22090 and r22109, ompi_info started (erroneously)
requesting CPUs.
E.g., r22090 is good:
% ompi_info | grep Open MPI:
Open MPI: 1.7a1r22090
But r22109 is bad:
% ompi_info | grep Open MPI:
--------------------------------------------------------------------------
Your job has requested more cpus per process(rank) than there
are cpus in a socket:
Cpus/rank: 1
#cpus/socket: 0
Please correct one or both of these values and try again.

A component framework failed to open properly.
ompi_info will likely not display all configuration information
Open MPI: 1.7a1r22109
