Chapter 19 Setting Up MPI Debugging Sessions

Totalview® for HPC User Guide : PART IV Advanced Tools and Customization : Chapter 19 Setting Up MPI Debugging Sessions

This chapter discusses how to set up TotalView MPI debugging sessions for various environments and special use cases, as well as some application-specific debugging tasks. In most cases, you can just use the basic procedure, discussed in "Starting MPI Programs Using File > Debug New Parallel Program".

For information on setting up non-MPI parallel programs, see “Setting Up Parallel Debugging Sessions” on page 497.

NOTE >> For TotalView Individual, all your MPI processes must execute on the computer on which you installed TotalView. Further, you are limited to no more than 16 processes and threads.

This chapter describes the basics on setting up to debug an MPI system ("Debugging MPI Programs"), as well as the following MPI systems:

• "MPICH Applications"

• "MPICH2 Applications"

• "Cray MPI Applications"

• "IBM MPI Parallel Environment (PE) Applications"

• "IBM Blue Gene Applications"

• "Open MPI Applications"

• "QSW RMS Applications"

In addition, it includes these topics specific to MPI applications:

• "Starting MPI Issues"

• "Using ReplayEngine with Infiniband MPIs"
