A–mpirun Options Summary
Format Options
IB6054601-00 H A-7
A
Format Options
-l, -label-output
This option labels each line of output on stdout and stderr with the rank of the
MPI process that produces the output.
-y, -labelstyle string
This option specifies the label that is prefixed to error messages and statistics.
Process rank is the default prefix. The label that is prefixed to each message can
be specified as one of the following:
Other Options
-h -help
This option prints a summary of mpirun options, then exits.
-stdin filename
This option specifies the filename that must be fed as stdin to the node program.
Default: /dev/null
-stdin-target 0..np-1 | -1
This option specifies the process rank that must receive the file specified with the
-stdin option. Negative one (-1) means all ranks.
Default: -1
-v, -version
This option prints the mpirun version, then exits.
-wdir path-to-working_dir
This option sets the working directory for the node program.
Default: -wdir current-working-dir
%n Hostname on which the node process executes
%r Rank of the node process
%p Process ID of the node process
%L LID (InfiniPath local identifier (LID) adapter identifier) of the node
%P InfiniPath port of the node process
%l Local rank of the node process within a node
