Actor, an Elegant Model for Concurrent and Distributed Computation
summary
Presents the actor model as an alternative to native threads and shared-memory synchronization for exploiting multicore architectures. Uses the design of a video game to demonstrate what an actor is, how actors interact without shared memory, how actors communicate across a distributed system, and how to build a fault-tolerant distributed actor system.
