Setting Up Parallel Debugging Sessions

This chapter explains how to set up TotalView parallel debugging sessions for applications that use the following parallel execution models.

The information in this chapter describes running many different environments on many different architectures. While there is a lot of information in this chapter you do need, you probably don't need the information on many of the environments and architectures. This means that you shouldn't just read this chapter. Instead, go to this book's table of contents and decide what's important to you.

This chapter discusses:

• Debugging MPICH Applications
• Debugging HP Alpha MPI Applications
• Debugging HP MPI Applications
• Debugging IBM MPI (PE) Applications
• Debugging QSW RMS Applications
• Debugging SGI MPI Applications
• Debugging Sun MPI Applications
• Debugging OpenMP Applications
• Debugging PVM and DPVM Applications
• Debugging Shared Memory (SHMEM) Code
• Debugging UPC Programs
• Parallel Debugging Tips

There are a few things that are of general interest:

• TotalView lets you decide which process you want it to attach. You will find information in Attaching to Processes.
   
• If you're using a messaging system, TotalView displays this information visually as a message queue graph and textually in a message queue window.
   
• The end of this chapter has some hints on how you can approach debugging parallel programs.
