Compiling FlashAttention from SQL: new demo draws attention
Original: Show HN: Automatic deduction of FlashAttention kernel from ~25 lines of SQL
A developer has shown a system that automatically derives a FlashAttention GPU kernel from roughly 25 lines of SQL. The demo, posted on GitHub as part of an xarray-sql project, suggests high-level declarative code can be lowered into optimized attention kernels. Readers are debating how the compiler achieves the transformation and what it means for writing machine learning code without hand-tuned kernels.
Why now: The surprising claim that a famous GPU kernel can be generated automatically from short SQL code is drawing curiosity and skepticism.
