Researchers have developed Axon, a novel superoptimizer designed to enhance the performance of tensor programs for AI accelerators. Axon employs program synthesis to automatically generate target instructions from semantic specifications and empirically selects the most efficient kernel by exploring semantically equivalent program variations. The system discovers algebraic transformations through operator propagation in computation graphs, utilizing SMT solvers to ensure semantic preservation without manual rewrite rules. It then translates tensor operations into target ISA instructions, optimizes tiling configurations based on hardware constraints, and fuses operators to minimize memory traffic. AI
