Updates in 2025.2 — NsightCompute 13.1 documentation

# Updates in 2025.2

General

> - Added support for collecting C2C link information on Blackwell GPUs.

> - CPU call stack filtering now supports Python call stacks.

> - Instruction statistics now show warp- and thread-level instruction counts per opcode category. Added new metrics `sass__inst_executed_per_opcode_category` and `sass__thread_inst_executed_per_opcode_category`. See the Metrics Reference for details.

> - Enhanced several rules to produce tables pointing to the source location of interest.

> - Improved the NvRules API to support generic tables for the UI and CLI.

> - Improved the NvRules and Python Report Interface documentations to be more pythonic.

> - Added APIs to the Python Report Interface for querying rules and source markers in the report.

> - Added Occupancy Calculator Python Interface, which provides a Python-based interface for performing occupancy calculations and analysis of kernels on NVIDIA GPUs.

NVIDIA Nsight Compute

- Added product-wide search functionality via a new search bar and tool window.

- The Source page now shows scoreboard dependencies in SASS.

- Converted more tooltips into interactive tooltips. Interactive tooltips can now be pinned and dragged.

- Added source correlation navigation controls which allow navigation to the previous or next block of correlated lines.

NVIDIA Nsight Compute CLI

- Added support for profiling MPS applications.

- Added support for filtering kernels based on a renamed kernels configuration during profiling.

Resolved Issues

- CUDA Graphs in the Resources View use the current UI theme.

- Resolved several issues when interacting with timelines on the Details page.

- Resolved issues with Python syntax highlighting on the Source page.

- Disabled deprecated columns in the API Stream tool window.

- Fixed that the Source page may show incorrect correlation when some source files were not resolved.

- Reduced the number of replay passes required for collecting the `PmSampling.section` on GH100 with applicable drivers.

- Resolved that `--native-include` did not work properly when using range replay and `cu(da)ProfilerStop`.

- Fixed an `Invalid or unsupported charset:ANSI_X3.4-1968` error when using the CLI on some systems.

- Fixed that memory available for saving context state during replay may be computed incorrectly when the app was using managed memory.

- Fixed that some metrics were not listed for collection in section files for GB20x GPUs.
