Debugging Sun MPI Applications

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

TotalView 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:

1	Enter the following command:

totalview mprun [ totalview_args ] –a [ mpi_args ]

For example:

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

CLI: totalviewcli mprun [ totalview_args ] –a [ mpi_args ]

When the TotalView Process Window appears, select the Go button.­

CLI: dfocus p dgo

TotalView may display a dialog box with the following text:

Process mprun is a parallel job. Do you want to stop

the job now?

2	If you compiled using the –g option, click Yes to open a Process Window that shows your source. All processes are halted.
