Random thought - please shoot it down if crazy...
Would it make any sense to expose system/environmental/thermal
information to the application via MPI_T ?
For our sort of systems with a grab bag of jobs it's not likely
useful, but if you had a system dedicated to running an in house code
then you could conceive of situations where you might want to react to
over-temperature cores, nodes, etc.
