Parallel and Thread-Safe Ruby at High-Speed with TruffleRuby

Description

Array and Hash are used in every Ruby program. Yet, current implementations either prevent the use of them in parallel (the global interpreter lock in MRI) or lack thread-safety guarantees (JRuby raises an exception on concurrent Array#<<). Concurrent::Array from concurrent-ruby is thread-safe but prevents parallel access. This talk shows a technique to make Array and Hash thread-safe while enabling parallel access, with no penalty on single-threaded performance. In short, we keep the most important thread-safety guarantees of the global lock while allowing Ruby to scale up to tens of cores!
