 Sometime ago I wrote some code to detect if a node is infiniband enabled or not, and based on the result, add command line arguments to the mpirun invocation.  If you use that code, you will need to change:  the path to obtain the port status (/usr/bin/ibv_devinfo) and in the block specifing the interface change eth1 to ib0. Sometime ago I wrote some code to detect if a node is infiniband enabled or not, and based on the result, add command line arguments to the mpirun invocation.  If you use that code, you will need to change:  the path to obtain the port status (/usr/bin/ibv_devinfo) and in the block specifing the interface change eth1 to ib0.
