Ray: A Distributed System for AI

As machine learning algorithms and techniques have advanced, more and more machine learning applications require multiple machines and must exploit parallelism. However, the infrastructure for doing machine learning on clusters remains ad-hoc. While good solutions for specific use cases (e.g., parameter servers or hyperparameter search) and high-quality distributed systems outside of AI do exist (e.g., Hadoop or Spark), practitioners developing algorithms at the frontier often build their own systems infrastructure from scratch. This amounts to a lot of redundant effort.Continue reading
