Co-Array Collectives: Refined Semantics for Co-Array Fortran
Co-array notation provides a compact syntax for programming parallel programs. Co-array Fortran (CAF) introduced and implements this notation, and CAF is currently proposed as an extension to the Fortran language standard. We believe that co-array notation requires a revised semantic definition beyond that specified by CAF for both pragmatic reasons within Fortran and to make the notation attra...
متن کاملCompiler Support for Machine-independent Parallel Programming in Fortran D Compiler Support for Machine-independent Parallel Programming in Fortran D
Because of the complexity and variety of parallel archi-tectures, an eecient machine-independent parallel programming model is needed to make parallel computing truly usable for scientiic programmers. We believe that Fortran D, a version of Fortran enhanced with data decomposition speciications, can provide such a programming model. This paper presents the design of a prototype Fortran D compil...

متن کاملA Performance Measurement Infrastructure for Co-array Fortran
Co-Array Fortran is a parallel programming language for scientific applications that provides a very intuitive mechanism for communication, and especially, one-sided communication. Despite the benefits of this integration of communication primitives with the language, analyzing the performance of CAF applications is not straightforward, which is due, in part, to a lack of tools for analysis of ...
متن کاملForOpenCL: transformations exploiting array syntax in Fortran for accelerator programming
Emerging GPU architectures for high performance computing are well suited to a data-parallel programming model. This paper presents preliminary work examining a programming methodology that provides Fortran programmers with access to these emerging systems. We use array constructs in Fortran to show how this infrequently exploited, standardized language feature is easily transformed to lower-le...
