Debugging Memory Problems with MemoryScape : Chapter 4 Creating Programs for Memory Debugging : Setting Up MPI Debugging Sessions : Debugging Sun MPI Applications : Attaching to a Sun MPI Job
Attaching to a Sun MPI Job
To attach to an already running mprun job:
1 Find the host name and process identifier (PID) of the mprun job by typing mpps -b. For more information, see the mpps(1M) manual page.
The following is sample output from this command:
JOBNAME MPRUN_PID MPRUN_HOST
cre.99 12345 hpc-u2-9
cre.100 12601 hpc-u2-8
2 Go to Attach to Running Program and look for the process.
3 If MemoryScape is running on a different node than the mprun job, enter the host name in the Remote Host field.

You must link the MemoryScape agent into your Sun MPI Parallel Environment program before running it. For details, see Linking Your Application with the Agent”.
