NVIDIA Nsight Compute 2022.1
NVIDIA® Nsight™ Compute is an interactive kernel profiler for CUDA applications. It provides detailed performance metrics and API debugging via a user interface and command line tool. In addition, its baseline feature allows users to compare results within the tool. Nsight Compute provides a customizable and data-driven user interface and metric collection and can be extended with analysis scripts for post-processing results.
Version 2022.1 New Features | Revision History
- Rooflines provide a visual representation memory and compute capacities of your system.
- Analysis pinpoints your achieved arithmetic intensity and FLOP performance with respect to these limitations.
- This visualization guides the direction and value of optimization efforts
- For more information, see our
Memory Workload Analysis
- Visualize Memory throughput on the profiled platform and follow guided analysis for improving performance
- For NVIDIA Ampere and later architectures:
- Compute Data Compression throughput and ratio, to ensure data is compacted for maximum performance
- Asynchronous Copy metrics, validates the most direct route to shared memory
- View our 2020.1 Spotlight, GTC 2020, Super Computing 2020, and GTC 2021 videos
- Read our "NVIDIA Ampere Architecture and NVIDIA Nsight Developer Tools" blog
- Set multiple baselines to compare variations in GPU architecture, kernel launch parameters, memory usage, ...
- Compare performance metrics between baselines and the current run, including the ability to compare child processes
Run from Nsight Compute GUI or from Console Command Line
- Nsight Compute GUI provides text for console commands
- GUI/Console provide similar features, functionality, output, and reports
CUDA Task Graph Profiling
- Stop at a kernel launch from a graph node
- State of graph node shown in resource page
- Export graph visualization
- Correlate individual Source, SASS, or PTX lines and metrics
- Shown here with PC Sampling data available in Volta and Turing architectures
- Heat map for identifying high metric values
Nsight Compute integrates into Visual Studio using NVIDIA Nsight Integration
Visual Studio project settings are transferred to the Nsight Compute
Other Features
- Interactive kernel profiler
