Debugging OpenMP Applications

TotalView supports many OpenMP, C, and Fortran compilers. Supported compilers and architectures are listed in the TotalView Platforms and Systems Requirements document.

The following are some 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 supported compilers.

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

Topics in this section are:

“Debugging OpenMP Programs”

“Viewing OpenMP Private and Shared Variables”

“Viewing OpenMP THREADPRIVATE Common Blocks”

“Viewing the OpenMP Stack Parent Token Line”
