- Section files support descriptions

- The default sections and rules directory has been renamed to sections

NVIDIA Nsight Compute

- Added new profiling options to the options dialog

- Details page shows rule result icons in the section headers

- Section descriptions are shown in the details page and in the sections tool window

- Source page supports collapsing multiple source files or functions to show aggregated results

- Source page heatmap color scale has changed

- Invalid metric results are highlighted in the profiler report

- Loaded section and rule files can be opened from the sections tool window

NVIDIA Nsight Compute CLI

- NVIDIA Nsight Compute CLI uses a temporary file if no output file is specified

- Support for new `--quiet` option

- Support for setting the GPU clock control mode using new `--clock-control` option

- Details page output shows the NVTX context when `--nvtx` is enabled

- Support for filtering kernel launches for profiling based on their NVTX context using new `--nvtx-include` and `--nvtx-exclude` options

- Added new `--summary` options for aggregating profiling results

- Added option `--open-in-ui` to open reports collected with NVIDIA Nsight Compute CLI directly in NVIDIA Nsight Compute

Resolved Issues

- Installation directory scripts use absolute paths

- OpenACC kernel names are correctly demangled

- Profile activity report file supports a relative path

- Source view can resolve all applicable files at once

- UI font colors are improved

- Details page layout and label elision issues are resolved

- Turing metrics are properly reported on the Summary page

- All byte-based metrics use a factor of 1000 when scaling units to follow SI standards

- CSV exports properly align columns with empty entries

- Fixed the metric computation for double_precision_fu_utilization on GV11b

- Fixed incorrect ‘selected’ PC sampling counter values

- The SpeedOfLight section uses ‘max’ instead of ‘avg’ cycles metrics for Elapsed Cycles
