Talking to your GPU with the Vulkan API and Rust: (Ep 2)

🎥 🔴 𝐕𝐢𝐝𝐞𝐨 𝐃𝐫𝐨𝐩: A new year, a new series

In Part 2 of my new series on GPU programming with Vulkan and Rust, we dive deeper into how applications communicate with GPUs and why Vulkan shines as a modern GPU API.

If you missed Episode 1, I introduced Vulkan’s modular architecture, walked through setting up Ash (Rust bindings for Vulkan’s C API), and demonstrated how to check Vulkan’s terminal output.

In Episode 2, we explore the software pipeline for GPU communication. Here’s what I cover:
Key components: Application, Vulkan runtime, drivers, and the command queue.
GPU-side processes: Command processing, decoding, dispatching, and task scheduling.
CPU-GPU collaboration: How they synchronize and communicate efficiently.
Command queues (ring buffers): What they are and how GPUs use them to manage tasks.
Practical demo: Sending a transfer command to fill a GPU buffer and debugging the output.

This episode peels back the layers to show how CPUs command and control GPUs behind the scenes. If you’re curious about GPU programming or love exploring the inner workings of modern hardware, you’ll enjoy this one!
