Debugging Sun MPI Applications

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

MemoryScape can debug a Sun MPI program and can display Sun MPI message queues. This section describes how to perform job startup and job attach operations.

To start a Sun MPI application, use the following procedure, type the following command:

memscape mprun [ totalview_args ] –a [ mpi_args ]

For example:

memscape mprun –g blue –a –np 4 /usr/bin/mpi/conn.x

When the MemoryScape Window appears, select the Go button.
