TotalView

TotalView will help you to visualize and debug parallel programs. You just include the debug switch when you compile, then invoke your program with appropriate debugger options.
TotalView is currently available on AVIDD and the Research SP.
It's featured in our parallel programming class notes:
- On the AVIDD cluster: Getting Started with MPI
- On the IBM SP: Older MPI Tutorial notes (Note: Information on the 2003 tutorial may be dated)
TotalView comes from Etnus. They have a pretty cool Getting Started document and a collection of TotalView Tips.

The current TotalView IU license is for up to 32 processes and limited to two simultaneous users across all platforms: IBM SP, AVIDD Intel Cluster and departmental systems (except Intel-IA64 linux, a separate license for one user at a time is available for Intel-IA64 linux avidd-i64 and departmental systems).
