I needed to reverse where stdout and stderr get their input. So I needed an extra fd. I just went with 3. 4 through 9 would have worked as well. And 3>&- just closes fd 3. At that point we're done with it, so there's no point in leaving it open while the program actually runs.

1. The way I choose is - touch a file with "now - 2 hours", then use fine with '! -newer'
2. Do you have any other idea to do it ?

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

-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.
