Hi, @trsh

Thanks for the feature request!

The Linux + AMD support is planned. However, developing a new backend might take months. We'll update this issue if any progress is made.

@Mike-Leo-Smith webgpu would be a very exotic backend, covering also webs.

Thanks for the information!

WebGPU seems like a promising candidate. We'll investigate and see if it's possible to lower LuisaCompute's DSL and runtime features to it.

Update: we plan to re-implement the IR (formerly in src/rust and src/ir). The new IR will be interconvertible with SPIR-V to support the Vulkan backend's code generation needs. This should also help other IR-level transformations, like automatic differentiation, by incorporating SPIRV-Opt's optimization passes.

Vulkan backend is working in progress.
