Subject: Re: [OMPI users] Printing information on computing nodes.

So there is no solution? e.g. my 2 computers that are computing nodes
and are placed in different room on different floors. And the target
user wants to monitor the progress of computation independently which
have to be printed on their lcd monitors.
