QLogic OFED+ Host Software User Guide, Rev. B

A–mpirun Options Summary
Shell Options
Shell Options
-shell shell-name
This option specifies the name of the program to use to log into remote hosts.
Default: ssh, unless $MPI_SHELL is defined.
-shellx shell-name
This option specifies the name of program to use to log into remote hosts with X11
forwarding. This option is useful when running with -debug or in xterm.
Default: ssh, unless $MPI_SHELL_X is defined.
Debug Options
-debug
This option starts all the processes under debugger, and waits for the user to set
breakpoints and run the program. The gdb option is used by default, but can be
overridden using the -debugger argument. Other supported debuggers are
strace and the QLogic debugger pathdb.
-debug-no-pause
This option is similar to -debug, except that it does not pause at the beginning.
The gdb option is used by default.
-debugger gdb|pathdb|strace
This option uses the specified debugger instead of the default gdb.
-display X-server
This option uses the specified X server for invoking remote xterms. (-debug,
-debug-no-pause, and -in-xterm options use this value.)
Default: whatever is set in $DISPLAY
-in-xterm
This option runs each process in an xterm window. This is implied when -debug
or -debug-no-pause is used.
Default: write to stdout with no stdin
-psc-debug-level mask
This option controls the verbosity of messages printed by the MPI and InfiniPath
protocol layer. The default is 1, which displays error messages. A value of 3 displays
short messaging details such as source, destination, size, etc. A value of FFh prints
detailed information in a messaging layer for each message. Use this option with care,
since too much verbosity will negatively affect application performance.
Default: 1
-xterm xterm
This option specifies the xterm to use.
Default: xterm
