Supporting Array Programming in X10

Abstract

Effective support for array-based programming has long been one of the central design concerns of the X10 programming language. After significant research and exploration, X10 has adopted an approach based on providing arrays via user definable and extensible class libraries. This paper surveys the range of array abstractions available to the programmer in X10 2.4 and describes the key language features and language implementation techniques necessary to make efficient and productive implementations of these abstractions possible..
