Towards Device-agnostic PyTorch: Building Unified Infrastructure for a Multi-Backend Ecos... - W. Li

AI computing has moved from chips to platforms, and now to ecosystems. Cambricon's decade-long journey has proven that scale demands full-stack co-optimization—and we are taking that expertise upstream. With an upstream-first philosophy and a track record of real contributions, we are hardening PyTorch's device-agnostic foundation for every PrivateUse1 backend. Our goal: fixes upstream, seamless everywhere. Device-agnostic is just the enabler; the real prize is unlocking what each backend does best—broader device reach and richer backend-native capabilities.
