Ralph, orte-ps is a valuable addition to OpenMPI and one that allows me to build my tool on top of it, I couldn't even begin to work without it.
Could I request that the pid and hostname of the orterun process are included in the output, I can manage without it for the time being but I can see it'll be necessary to have it when it comes to tighter integration with other software.
