Add a comment. 2. Quite a simple way to debug an MPI program. In main () function add sleep (some_seconds) Run the program as usual. $ mpirun -np <num_of_proc> <prog> <prog_args>. Program will start and get into the sleep. So you will have some seconds to find you processes by ps, run gdb and attach to them.
