Query: AI Powered Compiler Techniques for DL Code Optimization   Creating high performance implementations of deep learning primitives on CPUs
is a challenging task. Multiple considerations including multi-level cache
hierarchy, and wide SIMD units of CPU platforms influence the choice of program
transformations to apply for performance optimization. In this paper, we
present machine learning powered compiler techniques to optimize loop nests. We
take a two-pronged approach to code optimization: We first apply high level
optimizations to optimize the code to take optimal advantage of the cache
memories. Then, we perform low level, target-specific optimizations to
effectively vectorize the code to run well on the SIMD units of the machine.
For high level optimizations, we use polyhedral compilation techniques and deep
learning approaches. For low level optimization, we use a target specific code
generator that generates code using vector intrinsics and Reinforcement
Learning (RL) techniques to find the optimal parameters for the code generator.
We perform experimental evaluation of the developed techniques on various
matrix multiplications that occur in popular deep learning workloads. The
experimental results show that the compiler techniques presented in the paper
achieve 7.6X and 8.2X speed-ups over a baseline for sequential and parallel
runs respectively.
