OMPI-IOF(1) Open MPI OMPI-IOF(1)NAME
ompi-iof, orte-iof - Displays a copy of the output streams from a process.
NOTE: ompi-iof, and orte-iof are exact synonyms for each other. Using any of the names will result in exactly identical behavior.

Options
ompi-iof will display a copy of the indicated stdout, stderr, and/or stddiag streams from the designated process.
-pid | --pid
The pid of the mpirun executing the process whose streams are to be copied
-stdout | --stdout
Display a copy of the specified process' stdout. If no options are specified, this will act as the default
-stderr | --stderr

-stddiag | --stddiag

DESCRIPTION
ompi-iof displays a copy of the indicated stdout, stderr, and/or stddiag streams from the designated process. At this time, a ctrl-C must
be used to terminate the program. The program will terminate cleanly, telling the associated mpirun to close the requested streams before
exiting.
