You should see one line of output for each rank, as well as debug output indicating the TCP/IP-

capable network fabric is being used.

5. Test the shared-memory and DAPL-capable network fabrics using:

$ mpiexec -n 2 -env I_MPI_DEBUG 2 -env I_MPI_FABRICS shm:dapl ./myprog

You should see one line of output for each rank, as well as debug output indicating the shared-

memory and DAPL-capable network fabrics are being used.

6. Test any other fabric using:

mpiexec -n 2 -env I_MPI_DEBUG 2 -env I_MPI_FABRICS <fabric> ./myprog

where <fabric> can be a supported fabric. For more information, see Selecting a Network

Fabric.

For each of the mpiexec commands used, you should see one line of output for each rank, as well

as debug output indicating which device was used. The device(s) should agree with the

I_MPI_FABRICS setting.
