NOTE >> The ReplayEngine toolbar appears only on supported platforms, which are Linux x86-32 and Linux x86-64.
In the Settings (middle item), you can control which toolbars are displayed, and request that the toolbar items include descriptive text:
Another set of toolbars to support CUDA debugging is available when a CUDA program is being run. While you can display these at any time, they are responsive only when TotalView is debugging a CUDA program. See "GPU Toolbars".
