- -p plane
Specifies the fabric plane the test will run on. The specified plane needs to be defined and enabled in the Mgt config file. Default is the first enabled plane.
- -f hostfile

- -n numprocs
Number of processes per host for NIC-SW test. Default is 3.
- start
Starts the NIC-SW tests.
- stop

The NIC-SW cable test requires that the FF_MPI_APPS_DIR is set, and it contains a pre-built copy of the Intel(R) mpi_apps for an appropriate message passing interface (MPI).
