mpirun_openib is a tool that enables programs linked with the MVAPIch MPI library to run on a ParaStation MPI cluster under control of the ParaStation MPI management facility. Within ParaStation MPI the startup of parallel jobs is handled as described within the process_placement(7) manual page. The spawning mechanism is steered by environment variables, which are described in detail within ps_environment(7).
mpirun_openib typically works like this:
mpirun_openib -npnum
prog
[args
]
This will startup the program prog
num
times in parallel forming a
parallel job.
Args
are optional argument which will be
passed to each instance of prog.
-np nodes
Number of processes to create.
-nodes=nodeslist
list of nodes to use.
-hosts=hosts
list of hosts to use.
-hostfile=hostfile
hostfile to use.
-sort=criteria
Sorting criterion to use: proc
,
load
,
proc+load
or
none
.
-exports=envlist
Environment to export to foreign nodes.
-v, --verbose
Print diagnostic messages.
-V, --version
Output version information and exit.
-?, --help
Show this help messages.
--usage
