Build MPI Test Apps and Copy to Hosts
(Host) This will build the MPI sample benchmarks on the InfiniBand Management
Node and copy the resulting object files to all the hosts. This is in preparation for
execution of MPI performance tests and benchmarks in a later step.
Reboot Hosts
(Linux) This will run the iba_host_admin reboot command to reboot all the
selected hosts and ensure they go down and come back up (as verified using ping
over the management network). When the hosts come back up, they will be
running the InfiniBand software installed.
Refresh SSH Known Hosts
(Linux) This will run the setup_ssh -U “” command to refresh the ssh known
hosts list on this server for the Management Network. This may be used to update
security for this host if hosts are replaced, reinstalled, renamed, or repaired.
Rebuild MPI Library and Tools
(Host) This will rebuild the MPI Library itself and related tools (such as mpirun).
This will be performed using the do_build tool supplied with the MPI Source.
When rebuilding MPI,
do_build will prompt the user for selection of which MPI
(openmpi, mvapich or mvapich2) to rebuild and provide choices as to which
available compiler to use. Consult the QLogic HCA and QLogic OFED Software
Users Guide for more information.
Run a command on all hosts
(Linux) This will run the cmdall command. A Linux shell command (or sequence
of commands separated by semicolons) may be specified to be executed against
all selected hosts.
Copy a file to all hosts
(Linux) This will run the scpall command. A file on the local host may be
specified to be copied to all selected hosts.
NOTE:
This option is available for the QLogicIB packaging of OFED, but is not
presently available for other packagings of OFED.
