NVTX

A safe and ergonomic #![no_std] crate to bind the NVIDIA® Tools Extension SDK (NVTX) with zero-cost abstraction.

NVIDIA® Tools Extension SDK (NVTX) is a C-based Application Programming Interface (API) for annotating events, code ranges, and resources in your applications. Official documentation for NVIDIA®'s NVTX can be found here.

This library is a wrapper over that SDK, safely, and with zero-cost abstractions. This library facilitates integration into the rich CPU and GPU profiling tools provided by NVIDIA®, such as NSight Systems. The primary motivation for this library is to assist research GPU analysts and bring NVIDIA® tools to Rust. This crate is #![no_std].

➡️ Quickstart

The crate is published on crates.io and the easiest way to use nvtx is by adding the dependency to your Cargo.toml file:

nvtx = "1.1.1"

There are several examples in the examples folder which can be executed through tools such as NSight Systems. Each example has a README document with easy to read steps, screenshots, and documentation. Check out the first example, 'Hello, World!'
