Apple Silicon's unified memory architecture enables zero-copy GPU inference from WebAssembly by allowing Wasm modules to share their linear memory directly with the GPU. The author explores this capability through Driftwood, a project using WebAssembly as a control plane and GPU as compute, eliminating the serialization overhead normally required on discrete GPUs. End-to-end tests demonstrate data flowing from Wasm memory through GPU computation back to the same pointer with no intermediate copying.

Zero-Copy GPU Inference from WebAssembly on Apple Silicon
WebAssembly running on Apple Silicon can now share GPU memory directly with zero-copy, eliminating the serialization overhead that typically bottlenecks GPU-accelerated inference on discrete GPUs.
