Debugging MPI Programs
Starting MPI Programs
MPI programs use a starter program such as mpirun to start your program. You can start these MPI programs in two ways: with the starter program under TotalView control, or using the GUI, in which case the starter program is not under TotalView control. In the first case, you will enter the name of the starter program on the command line. In the latter, you will enter program information into the File > Debug New Parallel Program or Process > Startup Parameters dialog boxes.
NOTE >> Programs started using GUI dialog boxes have some limitations: program launch does not use the information you set for single-process and bulk server launching, and you cannot use the Attach Subset command.
Starting MPI programs using the dialog boxes is the recommended method. This method is described in the next section. Starting using a starter program is described in various discussions throughout this chapter.
