• X Windows: X Windows is required on all platforms to run the NextGen UI.
• OpenMP: Most languages now support OpenMP. If your language supports it, and if your OpenMP code compiles successfully with one of our supported compilers, then your OpenMP is considered supported by TotalView for HPC.
Version information first lists compilers that support both C/C++ and Fortran, followed by compilers specific to one language or the other.
• CUDA debugging: Supported on Linux x86-64, Linux PowerLE/OpenPOWER, and Linux-arm64 operating systems. Current support is for the 8, 9, and 10 tool chains. Notes: 1) There is limited support for the Dynamic Parallelism feature; 2) On the NVIDIA Jetson Xavier Developer Kit, you must debug applications as root. For more information, please see the CUDA chapters in the TotalView for HPC NextGen User Guide.
• ReplayEngine for reverse debugging: Supported on Linux x86 and x86-64 operating systems. On other platforms, ReplayEngine buttons and menu selections are grayed out in the UI. For more information, please see the document Reverse Debugging with ReplayEngine.
Replay Engine supports the IP transport mechanism on most MPI systems. It supports communication over Infiniband using either the IBverbs or the QLogic PSM transport layers on some systems. Please see the section “Using ReplayEngine with Infiniband MPIs” in the TotalView for HPC Users Guide for details.
• Python debugging: Python 2.7 and 3.5 and above debugging is supported on Linux x86-64 operating systems. For more information, please see “Debugging Python” in the NextGen TotalView for HPC User Guide.
