Since MPICH is portable, it has no built-in debugging support. For
some devices, it is possible to start the root process under a
debugger, or to start the entire application under a parallel
debugger. The best debugging option for MPICH is the Totalview
debugger [8], a commercial product from Dolphin
Interconnect Solutions that is one of the best parallel debuggers
available. Totalview has a good GUI with an intuitive ``dive''
feature and a coherent approach to debugging parallel programs. It is
integrated with MPICH (the ch_p4, ch_shmem, and
ch_lfshmem devices), understands MPI communicators and MPI message
queues and ``captures'' MPI processes as they start. Totalview runs
on IBM RS6000, Sun and Digital platforms. By the end of 1997 it is
expected to run on SGI R10000 platforms as well.
