HP MPI ships with xmpi, the trace visualization tool originally developed as part of LAM. xmpi is well-integrated with HP MPI. An additional flag to the mpirun command causes MPI programs to automatically generate trace files that can be displayed by xmpi. Furthermore, xmpi can run an MPI application interactively. For more information about xmpi see Section 5.1.

HP MPI is integrated with the debugger cxdb. The cxdb interface isn't great, but it's adequate for simple tasks. Unfortunately it isn't able to show message queues.
