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.

Baseline Comparisons

  • Set mutliple baselines - Multiple architures shown above
  • Compare performance metrics between baselines and the current run

Run from NsCompute GUI or from Console Command Line

  • NsCompute GUI provides text for console commands
  • GUI/Console provide similar features, functionality, output, and reports
