🦀 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](https://www.youtube.com/watch?v=zypUzckmQFg) 2. [Squaring numbers with Vulkan](https://www.youtube.com/watch?v=wh-t9mijDt4) 3. Gray-Scott pipeline and dataset (this video) 4. [Gray-Scott simulation & optimizations](https://www.youtube.com/watch?v=MXRA1vK1uAo) This third session scales up most of our simple Vulkan compute building blocks to Gray-Scott simulation building blocks, as the following topics are covered: - Integrating Vulkan logging with indicatif progress bars. - Initializing GPU data directly on device. - Sharing code and data between GLSL compute pipelines. - Comparing strategies for mapping computations to GPU work-items. - Adapting most of the previous CPU simulation code to GPU computing needs.
