TotalView ((c)) is a powerful, commercial-grade, portable debugger for
parallel and multithreaded programs, available from Dolphin Interconnect
Solutions
( http://www.dolphinics.com/toolworks). TotalView understands
multiple MPI implementations, including MPICH. By ``understand'' is meant
that if you have TotalView installed on your system, it is easy to start your
MPICH program under the control of TotalView, even if you are running on
multiple machines, manage your processes both collectively and individually
through TotalView's convenient GUI, and even examine internal MPICH data
structures to look at message queues. The general operation model of
TotalView will be familiar to users of command-line-based debuggers such as
gdb or dbx.
