Debugging MPI Programs � TotalView lets you decide which process you want it to attach to. See “Attaching to Processes” on page 124. � See “Debugging Parallel Applications Tips” on page 124 for hints on how to approach debugging parallel programs. Debugging MPI Programs Starting MPI Programs MPI programs use a starter program such as mpirun to start your program. TotalView lets you start these MPI programs in two ways. One requires that the starter program be under TotalView control, and the other does not. In the first case, you will enter the name of the starter program on the command the line. In the other, you will enter program information into the File > New Program or Process > Startup Parameter dialog boxes. Programs started using these dialog boxes do not use the information you set for single-process and bulk server launching. In addition, you cannot use the Attach Subset command when entering information using these dialog boxes. Starting MPI programs using the dialog boxes is the recommended method. This method is described in the next section. Starting using a started program is described in various places throughout this chapter. Starting MPI Programs Using File > New Program In many cases, the way in which you invoke an MPI program within TotalView control differs little from discipline to discipline. If you invoke TotalView from the command line without an argument, TotalView displays its File > New Program dialog box. (See Figure 82 on page 99.) After entering program’s name (Start a new process should be selected by default), select the Parallel tab. (See Figure 83 on page 99.) You can now select the Parallel system, the number of Tasks, and Nodes. If there are additional arguments that need to the sent to the starter process, type them within the Additional starter arguments area. These arguments are ones that are sent to a starter process such as mpirun or poe. They are not arguments sent to your program. If you need to add and initialize environment variables and command-line options, select the Arguments tab and enter them. In most cases, TotalView will remember what you type between invocations of TotalView. For example, suppose you were debugging a program called 98 Chapter 6: Setting Up MPI Debugging Sessions
Figure 82: File > New Program Dialog Box Figure 83: File > New Program Dialog Box: Parallel Tab Debugging MPI Programs my_foo and set it up using these controls. The next time you start TotalView, you can use the following command: totalview my_foo TotalView will remember what you entered so there is no need to respecify these options.
