So the MCA parameter that you mention is explained at the link below:
http://osl.iu.edu/research/ft/ompi-cr/api.php#mca-opal_cr_use_thread
This enables/disables the C/R thread a runtime if Open MPI was
configured with C/R thread support:
The description for MCA parameter "opal_cr_use_thread" is very short at
URL: http://osl.iu.edu/research/ft/ompi-cr/api.php
Can someone explain the usefulness of enabling this parameter vs
disabling it? In other words, what are pros/cons of disabling it?
I found that this gets enabled
