Updates in 2024.1 — NsightCompute 12.6 documentation

# Updates in 2024.1

General

- Switched to using OpenSSL version 3.0.10.

- Added new metrics available when profiling on CUDA Green Contexts.

- Reduced the number of passes required for collecting PM sampling sections.

- Counter domains can now be specified for PM sampling metrics in section files.

- PM sampling metrics can now be queried in the command line and Metric Details window by specifying the respective `collection` option.

- Added a new optional PmSampling_WarpStates section for understanding warp stall reasons over the workload duration.

- Added a new rule for detecting load imbalances.

- Improved the performance of graph-level profiling on new drivers.

- Updated the metrics compatibility table for OptiX cmdlists and instruction-level SASS metrics.

- Improved PM sampling results by dynamically recollecting metrics to avoid outlier pass groups. Use the new pm-sampling-max-passes option to control the maximum number of dynamically replayed passes.

- Added interKernelCommunication sample CUDA application to show how to use NVIDIA Nsight Compute to profile kernels that depend on each other and must be launched concurrently. Refer to the `README.TXT` file and sample code under `extras/samples/interKernelCommunication`.

NVIDIA Nsight Compute

- Added SASS view and Source Markers support in Source Comparison.

- Improved Source Comparison diff visualization by adding empty lines on other side of inserted/deleted lines.

- The Source page column chooser can now be opened directly from the Navigation drop down.

- Added support to update a source-page profile.

- Added a Launch Details tool window for showing information about individual launches within larger workloads like OptiX command lists.

- Added support for CUDA Green Contexts in the Resources tool window, the Launch Statistics section and the report header.

- Property metrics can now be queried in the Metric Details window.

- Added support to show if a CUDA Graph kernel node is device-side updatable in the Resources tool window.

NVIDIA Nsight Compute CLI

- Improved documentation on NVTX expressions and command line output when a potentially incorrect expression led to no workloads being profiled.

- Improved checking for invalid expressions when using the `--target-processes-filer` option.

Resolved Issues

- Fixed that the L1 cache achieved roofline value was missing when profiling on GH100.

- Fixed several “Launch Failed” errors when collecting instruction-level SASS metrics.

- Fixed that Live Register values would be too high for some workloads.

- Fixed a scrolling issue on the Source page when collapsing a multi-file view.

- Fixed an issue that no PM sampling data would be shown in the timeline when context switch trace was not available.

- Fixed a display issue in the memory chart when adding baselines.

- Fixed a crash when adding baselines.

- Fixed a crash in timeline views when not all configured data was available.

- Fixed that the application history was not always deleted when selecting Reset Application Data.

- Fixed an error in the metric compatibility documentation.
