GDB Support for Debugging High Performance Computing Applications - Upstreaming

Learn about the challenges and solutions in debugging High Performance Computing (HPC) applications in this 17-minute technical talk that explores the evolution of Forge GDB's specialized features. Discover how the development team transitioned from maintaining a large out-of-tree patch set to an upstream approach, addressing complex debugging scenarios involving massive debug information, thousands of processes, and multiple compiler interpretations of DWARF. Explore how this strategic shift not only reduced maintenance costs from months to weeks but also made HPC debugging capabilities more accessible to a broader user base through standard distributions.
