mpirun (Open MPI) 1.4r18761-ct8.0-b24a-r134

Usage: mpirun [OPTION]... [PROGRAM]...

Start the given program using Open RTE

-amAggregate MCA parameter set file list

--appProvide an appfile; ignore all other command line

options

-bynode|--bynode Whether to allocate/map processes round-robin by

node

-byslot|--byslot Whether to allocate/map processes round-robin by

slot (the default)

-c|-np|--npNumber of processes to run

-cf|--cartofileProvide a cartography file

-d|--debug-devel Enable debugging of OpenRTE

-debug|--debug Invoke the user-level debugger indicated by the

orte_base_user_debugger MCA parameter

--debug-daemons Enable debugging of any OpenRTE daemons used by

this application

--debug-daemons-file Enable debugging of any OpenRTE daemons used by

this application, storing output in files

-debugger|--debugger

Sequence of debuggers to search for when "--debug"

is used

-default-hostfile|--default-hostfile

Provide a default hostfile

-display-allocation|--display-allocation

Display the allocation being used by this job

-display-map|--display-map

Display the process map just before launch

--do-not-launch Perform all necessary operations to prepare to

launch the application, but do not actually launch

it

-do-not-resolve|--do-not-resolve

Do not attempt to resolve interfaces

-gmca|--gmca

Pass global MCA parameters that are applicable to

all contexts (arg0 is the parameter name; arg1 is

the parameter value)

-h|--help This help message

-H|-host|--hostList of hosts to invoke processes on

--hetero Indicates that multiple app_contexts are being

provided that are a mix of 32/64 bit binaries

-hostfile|--hostfile

Provide a hostfile

-loadbalance|--loadbalance

Balance total number of procs across all allocated

nodes

-machinefile|--machinefile

Provide a hostfile

-mca|--mca

Pass context-specific MCA parameters; they are

considered global if --gmca is not used and only

one context is specified (arg0 is the parameter

name; arg1 is the parameter value)

-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

relative paths provided by --preload-files are

used.

-q|--quiet Suppress helpful messages

-s|--preload-binary Preload the binary on the remote machine before

starting the remote process.

--tmpdirSet the root for the session directory tree for

orterun ONLY

-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

"bar" in the started processes)

--xml Provide all output in XML format
