X10 is a type-safe, modern, parallel, distributed object-oriented language intended to be very easily accessible to Java programmers. It is targeted to future low-end and high-end systems with nodes that are built out of multi-core SMP chips with non-uniform memory hierarchies, and interconnected in scalable cluster configurations. X10 highlights the explicit reification of locality in the form of places; lightweight activities embodied in async, future, foreach, and ateach constructs; constructs for termination detection and phased computation; the use of lock-free synchronization; and the manipulation of global arrays and data structures.
