Nsight Compute Profiler Occupancy Report

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.

Roofline Analysis

Memory Workload Analysis

Baseline Comparisons

  • 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

Source Code Correlation

  • 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
