Operator optimization

Below is what the Enflame AI Infra experienced-hire first round covered; the interview focused on the compiler tech stack.

Compilers and frameworks

  1. MLIR representation and optimization flow (Enflame’s software stack is based on MLIR + LLVM)
  2. XLA’s weaknesses around dynamism and how to handle them (e.g. hand-written operators)
  3. Current state and limits of TVM auto code generation; performance comparison of hand-written NPU operators vs auto-generated ones
