Using -gtool for Debugging

runtime option can help you with debugging, when attaching to several processes at once. Instead of attaching to each process individually, you can specify all the processes in a single command line. For example:
> mpiexec -n 16 -gtool "gdb:3,5,7-9=attach" myprog.exe
The command line above attaches the GNU* Debugger (GDB*) to processes 3, 5, 7, 8 and 9.
