Chasing Bit-Equality Through a Wasm Actor Runtime

Agam Brahma

This is the second post in a series on Driftwood, a runtime for stateful Wasm actors with hardware-accelerated inference on Apple Silicon. The first post covered the zero-copy GPU path: that a Wasm actor's linear memory can be shared with the GPU without copying. This one covers a different...

Zero-Copy GPU Inference from WebAssembly on Apple Silicon

Agam Brahma

tl;dr: on Apple Silicon, a WebAssembly module's linear memory can be shared directly with the GPU: no copies, no serialization, no intermediate buffers. The CPU and GPU read and write the same physical bytes. End-to-end, it works: a Wasm guest fills a matrix in its linear memory, the GPU reads it,...
