Nsight Perf SDK Discuss all things related to the NVIDIA® Nsight Perf SDK - a graphics profiling toolbox for DirectX, Vulkan, and OpenGL, enabling you to collect GPU performance metrics directly from your application. Nsight Visual Studio Code Edition Nsight Visual Studio Code Edition is an extension to Visual Studio Code editor for CUDA programming and debugging. Nsight Copilot Nsight Copilot is NVIDIA’s AI-powered accelerated computing assistant. It provides intelligent code suggestions and assistance for CUDA development. Nsight Python Nsight Python is a Python-first GPU profiling framework API that automates performance analysis using Nsight tools. CUDA Developer Tools Welcome to the CUDA Developer Tools Forums. Nsight Systems Dicussions about the Nsight Systems suite of tools Nsight Eclipse Edition Edit, build, debug and profile CUDA-C applications directly within the Eclipse environment Nsight Compute 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. Nsight Aftermath SDK NVIDIA® Nsight™ Aftermath SDK is a simple library you integrate into your DirectX 12 game’s crash reporter to generate GPU "mini-dumps" when a TDR or exception occurs. Other Tools Discussions about tools not specifically addressed in other forum areas (OpenCV, cuvid, etc.) Nsight Visual Studio Edition Build, Debug, Profile and Trace heterogeneous compute and graphics applications using CUDA C/C++, OpenCL, DirectCompute, Direct3D, and OpenGL. Nsight Graphics Debug, profile, and export your graphical applications in a standalone developer tool Nsight DL Designer Nsight DL Designer is an integrated development environment that helps developers efficiently design and develop deep neural networks for in-app inference. CUPTI – CUDA Profiler Tools Interface CUPTI is a dynamic library that enables the creation of profiling and tracing tools that target CUDA applications. Nsight Cloud Nsight Cloud is a set of tools and utilities to help users enable the Nsight tools family on their cluster/cloud set up.
