If you have a question about this talk, please contact Jack Atkinson.

In this presentation I will cover an introduction to gdb (GNU’s general purpose debugger) and how to use it to search for bugs in your code. You might think why HPC applications? Sure, gdb can be used on pretty much any binary but I have a focus on High-Performance Computing and scientific software. Typically HPC applications run on supercomputers where local access or X-forwarding may not be possible or practical—this is where gdb really shines. I will also cover how to debug parallel applications that are built on the MPI programming model and my efforts to make this easier / less painful.

Hybrid Zoom details will be emailed to the RSE mailing list; if you are not on the list, please contact the organisers.
