#
[bug #1693]
WARNING: ConnectX XRC support was enabled together with coalescing
mode. This combination is not supported in this version of Open MPI
because it may cause random seg faults (please see Open MPI bug ticket
#1693 https://svn.open-mpi.org/trac/ompi/ticket/1693 for more
details). Message coalescing has been disabled in this job to prevent
catastrophic failure.
You can silence this warning either by disabling XRC (i.e., not specifying
an "X" queue in btl_openib_receive_queues) or disabling message
coalescing by setting the btl_openib_use_message_coalescing MCA
parameter to 0.
