Developers Question Bit-Level PyTorch Eager as Kernel Verification Gold Standard

Developers are debating whether kernel verifiers should treat bit-level equivalence with PyTorch Eager as the gold standard, as drisspg questions the assumption that PyTorch Eager's numerical implementation is definitive. The discussion draws on Edward Z. Yang's new essay "PyTorch: a reference language," which introduces the notions of a reference implementation and a reference language.
