vyre-driver-wgpu

wgpu backend for vyre IR: implements vyre::VyreBackend on any wgpu-capable GPU (Vulkan, DX12, Metal, WebGPU).

This crate is the 0.4.2 portable GPU fallback backend. It is a GPU fallback for systems where CUDA is not the target path, not a CPU fallback.

cargo add vyre vyre-driver-wgpu

Example

use vyre::ir::Program;
use vyre::{DispatchConfig, VyreBackend};
use vyre_wgpu::WgpuBackend;

let backend = WgpuBackend::new()?;
let program: Program = my_program();
let inputs: Vec<Vec<u8>> = vec![b"input data".to_vec()];
let config = DispatchConfig::default();

let outputs: Vec<Vec<u8>> = backend.dispatch(&program, &inputs, &config)?;

Features

Pipeline cache: reuses compiled WGSL pipelines across dispatches by content hash.
Buffer pool: reuses GPU buffer allocations across dispatches.
Validation cache: skips repeated capability checks for already-validated programs.
Lowering happens internally. Consumers never pass WGSL strings; the crate lowers Program through lowering::lower_with_features.
Release evidence must prove feature-surface coverage, backend metadata, and conformance for vyre-driver-wgpu@0.4.2.

Requirements

A wgpu-capable GPU. This crate does NOT silently fall back to CPU. Absence of a GPU is surfaced as an actionable error, not a degradation.
wgpu = 25.x. Pinned: major wgpu version bumps are a vyre-driver-wgpu major bump.

MSRV

Rust 1.85.
