The original poster wants two separate logs with stdout and stderr respectively and one with both of them in the correct order.

nice solution with the subshells , but unfortunately this does also not work at all.
This works well if you have outputs to stdout and stderr alternating, but if there is more then one lines written to one of stdout or stderr, the numbering increases for this one, but not for the other one ...

Just tried it out ...
You're right.
It just doesn't work.

orte-iof

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.

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.
