DescriptionThe HPC community is embracing the advantages of mixed-language development environments, presenting challenges for debugging and testing when application execution and data flow cross languages. How can we take advantage of the unique features offered by different languages while minimizing the impact on bug reproduction, root-cause analysis, and solution?
This interactive session walks through the current mixed-language HPC landscape to describe the problems with testing these types of applications and best-practice solutions using TotalView for HPC. You will learn how these architectures make it easy to “steer” computation between modules of different languages, to accelerate prototyping and development, and how advanced testing techniques provide visibility into the call stack and data for efficient debugging. The session will include presentation material and demonstrations using mixed Python and C/C++ applications.
