New in Classic TotalView for 2023.4

Classic TotalView includes the following primary new or updated features. For a complete change history for TotalView, MemoryScape and ReplayEngine, see the document “TotalView_for_HPC_Change_Log.pdf” in the PDF directory of your installation, or see the TotalView Change Log on the TotalView documentation page on the website.

Bug Fixes and Performance Improvements

Numerous bug fixes and performance improvements have been addressed, including performance improvements for data transformations.

New License Technology and Discovery

The Reprise License Manager (RLM) replaces both FlexNet Publisher (FNP) and FlexNet Embedded (FNE) licenses for new or renewing licenses. Existing customers using FNP or FNE will migrate to RLM beginning in 2024. In addition, license discovery has been simplified, as the installation creates a single license directory rather than directories specific to the type of license.

The New UI TotalView User Interface

To change between the new UI and the TotalView Classic UI, use the Preferences dialog on the Display menu. You can also launch the new UI with the -newUI switch:

totalview -newUI

New features added to the new, modern user interface in this release include:

Registers View

Examine CPU and GPU registers for target programs. Add them to the Data View to edit their value or cast to a different type.

Assembly View Early Access

Debug low-level machine instructions using the new Assembly view. Instruction-level stepping commands and breakpoints provide precise, fine-grained control.

C++ Type Transformations

Examine the data pointed to by an iterator to ease the debugging of STL collection data. See the Release Notes for a list of specific list of supported STL collection classes.
