NVIDIA Nsight Compute

Nsight Compute is an interactive profiling tool for CUDA and NVIDIA OptiX applications. It gathers detailed performance metrics, correlates them with source code, and offers API debugging through both a graphical user interface and a command‑line utility. The profiler can examine GPU throughput, warp state statistics, and memory workload, and it supports CUDA graphs and guided analysis to highlight optimization opportunities.

The tool is aimed at developers who need to tune kernel performance or troubleshoot OptiX pipelines. It presents hardware activity in a hierarchical view, allowing users to trace issues down to individual lines of code, and it includes built‑in guidance from NVIDIA engineers on common performance limiters. Results can be compared, post‑processed, and integrated into custom analysis workflows.

Nsight Compute can be extended with user‑defined metrics and integrates with the broader Nsight suite, including Nsight Systems and Nsight Graphics. It is distributed as part of the CUDA Toolkit and runs on macOS, offering a stable, production‑ready solution for GPU compute profiling.
