Configuring TotalView for Parallel Debugging
TotalView provides features and performance enhancements for scalable debugging in today’s HPC computing environments. In most cases, these require no special configuration. You can, however, customize a debugging session when working with multiprocess/multithreaded applications.
For example, you can configure how TotalView handles a dlopen event to support better performance if multiple shared libraries are being opened, or the debugger is processing multiple processes. You can also customize how TotalView handles system calls to execve() and fork(), in addition to other enhancements.
