Subject: [OMPI users] btl_tcp_if_include setting
From: Ray Sheppard (rsheppar_at_[hidden])
Date: 2013-10-14 10:27:35

   I am setting up version 1.7.2 for a Cray XE-6. The build nodes have
different interfaces than the compute nodes. I have been able to set it
up, but users need to embed the following into their mpirun command:
--mca btl_tcp_if_include ipogif0

Currently, The ompi_info shows as below. I have been trying to figure
out the correct configure switch to add to the build to remove the need
for a permanent mpirun switch, but seem to be not getting it right. Any
suggestions are welcomed. Thanks,
