dlopen Options for Scalability
When a target process calls dlopen(), a dlopen event is generated in TotalView. Because handling dlopen events impacts startup time for dynamically linked executables, TotalView provides ways to configure dlopen for better performance and scalability in HPC computing environments:
• Filtering dlopen events to avoid stopping a process for each event.
• Handling dlopen events in parallel to reduce client/server communication overhead with MRNet enabled.
