Rust on GPU 3/4 : Gray-Scott pipeline and dataset

Описание: 🦀 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](   • Rust on GPU 1/4: Introduction  )
2. [Squaring numbers with Vulkan](   • Rust on GPU 2/4: Squaring numbers  )
3. Gray-Scott pipeline and dataset (this video)
4. [Gray-Scott simulation &
optimizations](   • Rust on GPU 4/4 : Gray-Scott simulation & ...  )

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.
