NVIDIA Nsight Compute 2020.1

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 2020.1 New Features | Revision History

NVIDIA® Nsight™ Compute is freely offered through the NVIDIA Registered Developer Program and as part of the CUDA Toolkit

Roofline Analysis

New in 2020.1: 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
