Abstract

Coarray Fortran (CAF) comprises a set of proposed language extensions to Fortran that are expected to be adopted as part of the Fortran 2008 standard. In contrast to prior open-source implementation efforts, our approach is to use a single, unified compiler infrastructure to translate, optimize and generate binaries from CAF codes. In this paper, we will describe our compiler and runtime implementation of CAF using an Open64-based compiler infrastructure. We will detail the process by which we generate a high-level intermediate representation from the CAF code in our compilers front-end, how our compiler analyzes and translate this IR to generate a binary which makes use of our runtime system, and how we support the runtime execution model with our runtime library. We have carried out experiments using both an ARMCI- and GASNet-based runtime implementation, and we present these results.
