    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 multiple baselines to compare variations in GPU architecture, kernel launch parameters, memory usage, ...
    • Compare performance metrics between baselines and the current run
    • New: Now with the ability to compare child processes

    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
