Debugging is an essential but also rather time consuming step during application development. Tools dramatically reduce the amount of time spent to detect errors.

These errors may also be detected with debuggers (preferably debuggers with support for parallel applications), however, specialized tools like MPI checking tools (e.g. Marmot) or thread checking tools (e.g. Intel Thread Checker) can simplify this task. The following sections provide detailed information about the different types of debugging tools:
