To run your instrumented application, use the ppwrun command in front of your application's run command invocation. Note that you must recompile your application first; for more information please see Compiling MPI Programs.
For instance, if you normally run your application using the following command:
$ srun -n 16 ./myapp 1 2 3
you would use this command instead:
$ ppwrun --output=myapp.par srun -n 16 ./myapp 1 2 3
For more information on the ppwrun command, please see ppwrun.
