Debugging IBM MPI Parallel Environment (PE) Applications

In many cases, you can bypass the procedure described in this section. For more information, see “Debugging MPI Programs”.

You can debug IBM MPI Parallel Environment (PE) applications on the IBM RS/6000 and SP platforms.

To take advantage of MemoryScape’s ability to automatically acquire processes, you must be using release 3,1 or later of the Parallel Environment for AIX.

Topics in this section are:

“Starting MemoryScape on a PE Program”

“You should tart all of your parallel tasks using the Run command.”

“Attaching to a PE Job”

The following sections describe what you must do before MemoryScape can debug a PE application.

You must link the MemoryScape agent into your IBM MPI Parallel Environment program before running it. For details, see “Installing tvheap_mr.a on AIX”.
