This paper introduces an expressive subset of X10, Flat X10, designed to permit efficient execution across multiple single-threaded places with a simple runtime and without compromising on the productivity of X10. We present the design, implementation and evaluation of a compiler and runtime system for Flat X10. The Flat X10 compiler translates programs into C++ SPMD programs communicating using an active messaging infrastructure. It uses novel techniques to transform explicitly parallel programs into SPMD programs. The runtime system is based on IBM's LAPI (Low-level API) and is easily portable to other libraries such as GASNet and ARMCI.
