I don't know if you are familiar with it but pdsh is a very useful parallel shell that uses a "$HOSTNAME: " syntax, going along with this there is a dshbak command which can take output in that form and present it to the user in a number of different ways. It would be a nice bonus if openmpi was to also able to benefit from this command. There is a dshbak manpage on-line but unfortunately no examples. Feel free to contact me on or off-list if I'm you want a example or further information. Ashley,
