The APGAS library: resilient parallel and distributed programming in Java 8

We propose the APGAS library for Java 8. Inspired by the core constructs and semantics of the Resilient X10 programming language, APGAS brings many benefits of the X10 programming model to the Java programmer as a pure, idiomatic Java library. APGAS supports the development of resilient distributed applications running on elastic clusters of JVMs. It provides asynchronous lightweight tasks (local and remote), resilient distributed termination detection, and global heap references. We compare and contrast the X10 and APGAS programming styles, review key design choices, and demonstrate that APGAS achieves performance comparable with X10.
