--cn_guid_file, -u <path to file>
Set the compute nodes for the Fat-Tree routing algorithm
to the guids provided in the given file (one to a line)
--io_guid_file, -G <path to file>
Set the I/O nodes for the Fat-Tree routing algorithm
to the guids provided in the given file (one to a line)
--port-shifting
Attempt to shift port routes around to remove alignment problems
in routing tables
--scatter-ports <random seed>
Randomize best port chosen for a route
--max_reverse_hops, -H <hop_count>
Set the max number of hops the wrong way around
an I/O node is allowed to do (connectivity for I/O nodes on top swithces)
--ids_guid_file, -m <path to file>
Name of the map file with set of the IDs which will be used
by Up/Down routing algorithm instead of node GUIDs
(format: <guid> <id> per line)
--guid_routing_order_file, -X <path to file>
Set the order port guids will be routed for the MinHop
and Up/Down routing algorithms to the guids provided in the
given file (one to a line)
--torus_config <path to file>
This option defines the file name for the extra configuration
info needed for the torus-2QoS routing engine. The default
name is '/etc/opensm/torus-2QoS.conf'
--once, -o
This option causes OpenSM to configure the subnet
once, then exit. Ports remain in the ACTIVE state.
--sweep, -s <interval>
This option specifies the number of seconds between
subnet sweeps. Specifying -s 0 disables sweeping.
Without -s, OpenSM defaults to a sweep interval of
10 seconds.
