Dear DGB users:
Is it possible that I use gdb to debug a MPI run on 4 processers. I
can't find any related documents around. Any suggestions? Many thanks.

It depends on which MPI you have.
For MPICH it's surely possible - you can have a gdb on each process and
switch between processes from your mpirun console.
For details see ch_p4 docs in $MPICH_HOME/doc.
Best regards,
Konstantin.
