Debugging SiCortex MPI Applications
The RMS prun command executes and starts all MPI processes. After
TotalView acquires them, it asks if you want to stop them at startup. If you
answer yes, TotalView halts them before they enter the main program. You
can then create breakpoints.
Attaching to an RMS Job
To attach to a running RMS job, attach to the RMS prun process that
started the job.
You attach to the prun process the same way you attach to other processes.
For details on attaching to processes, see “Attaching to Processes” on page 61.
After you attach to the RMS prun process, TotalView asks if you also want
to attach to slave MPICH processes. If you do, press Return or choose Yes.
If you do not, choose No.
If you choose Yes, TotalView starts the server processes and acquires all
MPI processes.
As an alternative, you can use the Group > Attach Subset command to predefine
what TotalView should do. For more information, see “Attaching to
Processes” on page 124.
Debugging SiCortex MPI Applications
In many cases, you can bypass the procedure described in this section. For more information,
see “Debugging MPI Programs” on page 98
Specific information on debugging SiCortex MPI applications is located in
our discussion of running TotalView on SiCortex platforms. See “Debugging
SiCortex Applications” on page 147 for information.
Debugging SGI MPI Applications
In many cases, you can bypass the procedure described in this section. For more information,
see “Debugging MPI Programs” on page 98.
