This information session starts off by tips on how to avoid bugs, and introduces the concept of assertions and unit tests. In many contexts command line debuggers are the only tool at hand, and the concepts transfer easily to GUI debuggers, so gdb will be taken as an example in a small case study. For debugging parallel code at scale, Allinea Forge’s DDT is introduced. This convenient GUI debugger allows to debug OpenMP, MPI as well as CUDA code. Some use cases for additional tools such as valgrind and strace will be mentioned as well.
