TotalView 2023.1 includes the following primary new or updated features. For a complete change history for TotalView, MemoryScape and ReplayEngine, see the TotalView Change Log on the TotalView documentation page on the website.

Optimization to user interface updates and debug event processing now results in faster debugging session launches, especially for large scale parallel jobs. These changes also improve UI updates during debugging operations, such as when quickly stepping through multiple lines of source code.

This release adds support for ROCm 5.4, as well as automatic discovery for target programs using the ROCm toolkit. As a result, the -rocm command line switch is no longer needed to debug ROCm programs.

Paint memory to find memory access problems for uninitialized or freed memory. For both newly allocated memory blocks and freed memory blocks, a hexadecimal paint pattern is written into the memory block, providing a consistent memory value for cases in which your program tries to read from those memory blocks. See the Release Notes for more detail.

Specify a working directory where TotalView will execute your target program. If not provided, the default is the directory from which you invoked TotalView. Define the working directory in either the UI or on the command line when starting TotalView. Modify it during a debug session using the Process > Modify Arguments menu or in the Sessions Manager.
