-n|--nNumber of processes to run
-nolocal|--nolocal Do not run any MPI applications on the local node
-nooversubscribe|--nooversubscribe
Nodes are not to be oversubscribed, even if the
system supports such operation
--noprefix Disable automatic --prefix behavior
-npernode|--npernode
Launch n processes per node on all allocated nodes
-ompi-server|--ompi-server
Specify the URI of the Open MPI server, or the name
of the file (specified as file:filename) that
contains that info
-path|--pathPATH to be used to look for executables to start
processes
-pernode|--pernode Launch one process per available node on the
specified number of nodes [no -np => use all
allocated nodes]
--prefixPrefix where Open MPI is installed on remote nodes
--preload-files
Preload the comma separated list of files to the
remote machines current working directory before
starting the remote process.
--preload-files-dest-dir
The destination directory to use in conjunction
with --preload-files. By default the absolute and

-tv|--tv Deprecated backwards compatibility flag; synonym
for "--debug"
-v|--verbose Be verbose
-V|--version Print version and exit
-wd|--wdSynonym for --wdir
-wdir|--wdirSet the working directory of the started processes
-xExport an environment variable, optionally
specifying a value (e.g., "-x foo" exports the
environment variable foo and takes its value from
the current environment; "-x foo=bar" exports the
environment variable name foo and sets its value to
