+Once these MPIs are built, using mpirun/mpiexec will result in the use
+of PSM by default -- no additional options needed.  Also if you have two 
+Intel True Scale HCAs per node, both of them will be used by default 
+when you run with 2 or more ranks per node.  No option is necessary on 
+the mpirun/mpiexec command.

+If you want to use just one of the HCAs, set the IPATH_UNIT variable to:
+export IPATH_UNIT=0   (or =1)
+If you have two Intel True Scale HCAs per node, and want to get additional 
+bandwidth performance even when only one MPI rank is active per node, set:

+For most applications, it is better not to use this PSM_MULTIRAIL variable
