To address these shortcomings, Rice University is developing a clean-slate redesign of the Coarray Fortran programming model. Rice's new design for Coarray Fortran, which we call Coarray Fortran 2.0, is an expressive set of coarray-based extensions to Fortran designed to provide a productive parallel programming model... Coarray Fortran (CAF) is a SPMD parallel programming model based on a small set of language extensions to Fortran 90. CAF supports access to non-local data using a natural extension to Fortran 90 syntax, lightweight and flexible synchronization primitives, pointers, and dynamic allocation of shared data. An executing CAF program consists of a static collection of asynchronous process images. Like MPI programs, CAF programs explicitly manage locality, data and computation distribution; however, CAF is a shared-memory programming model based on one-sided communication. Rather than explicitly coding message exchanges to obtain off-processor data, CAF programs can..
