Rust on GPU 1/4: Introduction

Description

🦀 How does one achieve excellent GPU performance in Rust, without tying oneself to one vendor or suffering the endless pain of low-quality cross-vendor compute toolchains? In this 1-day lecture at Gray Scott School 2025, Hadrien Grasland teaches the use of Vulkan compute shaders for numerical computations. Following the lecture schedule, the recording was cut in 4 parts. 1. Introduction, Vulkan vs competition, instance setup (this video) 2. Squaring numbers with Vulkan (https://www.youtube.com/watch?v=wh-t9mijDt4) 3. Gray-Scott pipeline & dataset (https://www.youtube.com/watch?v=0EBiLDuimNM) 4. Gray-Scott simulation & optimizations (https://www.youtube.com/watch?v=MXRA1vK1uAo) This first session explains the challenges of portable GPU computing, and the reasons why Vulkan is the most mature option available today for this purpose. It then covers the process of configuring a Vulkan instance, complete with some configuration recommendations for an optimal debugging experience.
