Subject: [OMPI users] Open MPI 1.5 is not detecting oversubscription
From: Jed Brown (jed_at_[hidden])

Previous versions would set mpi_yield_when_idle automatically when
oversubscribing a node. I assume this behavior was not intentionally
changed, but the parameter is not being set in cases of oversubscription,
with or without an explicit hostfile.
