If you can live with the processes starting normally and attaching gdb to them after they have started then you could use padb. Assuming you only have one job active (replace -a with the job-id if you don't) and watch to target the first spawned job then the following command will launch an xterm for each rank in the job and automatically attach to the process for you. padb -Oorte-job-step=2 --command -Ocommand="xterm -T %r -e 'gdb -p %p'" -a You'll need to use the SVN version of padb for this, the "orte-job-step" option tells it to attach to the first spawned job, use orte-ps to see the list of job steps.
