Debugging OpenMP Applications

TotalView provides explicit support for many OpenMP C and Fortran compilers. The compilers and architectures that we support are listed in the TotalView Platforms document and our Web site.

Here are some of the features that TotalView supports:

• Source-level debugging of the original OpenMP code.
   
• The ability to plant breakpoints throughout the OpenMP code, including lines that are executed in parallel.
   
• Visibility of OpenMP worker threads.
   
• Access to SHARED and PRIVATE variables in OpenMP PARALLEL code.
   
• A stack-back link token in worker threads' stacks so that you can find their master stack.
   
• Access to OMP THREADPRIVATE data in code compiled by the IBM and Compaq compilers.

The code examples used in this section are included in the TotalView distribution in the examples/omp_simple_f file.

Note:   On the SGI IRIX platform, you must use the MIPSpro 7.3 compiler or later to debug OpenMP.
