WebGPU / WGSL Memory Model
A relaxed, scoped memory model for portable GPU compute in the browser, derived closely from Vulkan's. WGSL provides relaxed atomics, work-group barriers and storage/work-group address spaces; implementations lower it to Vulkan, Metal or Direct3D 12.
Ordering relationships
- Compiles correctly to
- Vulkan Memory Model — Browser WebGPU implementations lower WGSL to Vulkan (and to Metal/Direct3D 12); the WGSL model is derived from Vulkan's.
- Apple Metal Memory Model — On Apple platforms WebGPU implementations lower WGSL to Metal.
