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

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.
