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.

SYNOPSIS

       ompi-iof [ options ]

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
		 Display a copy of the specified process' stderr.

       -stddiag | --stddiag
		 Display a copy of the specified process' stddiag.

       -rank | --rank
		 The rank of the process whose output is to be copied.

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.
