Updates in 2025.3 — NsightCompute 13.2 documentation

# Updates in 2025.3

General

- Added support for CUDA 13.0. See the tool’s CUDA driver system requirements.

- Added or improved support for Blackwell chips.

- For Green Context launches, `launch__waves_per_multiprocessor` is now scaled to the number of SMs in the Green Context.

- Added support for profiling individual nodes of device-launchable CUDA graphs launched from the host.

- Added metric `launch__persisting_l2_cache_size` to the Memory Workload Analysis section.

- Removed metric `profiler__pmsampler_dropped_samples`.

- Added support for not importing SASS cubins into the report.

NVIDIA Nsight Compute

- The Source page now shows the instruction category in SASS and the instruction mix for high-level source.

- Added a new instruction mix and scoreboard dependencies table to the Source page.

- Added improved tooltips to the memory chart.

- Added information on the GPC Constant Cache (GCC) and DSMEM atomics in the memory tables.

- The Metric Details tool window now shows the breakdown for throughput metrics.

- Added support for searching web forum and rule results.

- Multiple results from the same search source are now combined to make the output more readable.

- Improved the occupancy calculator.

NVIDIA Nsight Compute CLI

- Added the option –forward-signals to transparently forward signals to the profiled application.

Resolved Issues

- Fixed that some `ncu` console messages were truncated after 1024 characters.

- Fixed some display issues related to Green Context tables.

- Improved the performance of remote profiling in application replay mode.

- Fixed a hang in certain scenarios when profiling dependent kernels with device-mapped host allocations.

- Fixed missing correlation between JIT-compiled PTX to SASS in some situations.

- Fixed an error when profiling a CUDA graph kernel node doing a cluster launch on driver 580 or newer.
