A Critique of Co-array Features in Fortran
نویسندگان
چکیده
This note offers a critique of support for parallelism in Fortran 2008 based on co-arrays. We believe that there are some significant shortcomings in current design of co-array features that affect their suitability for mapping onto a range of parallel systems, expressing a wide range of parallel applications, supporting the development of parallel libraries, and providing an extensible framework for developing sophisticated parallel applications. Based on these shortcomings, we believe that it is premature to recommend to the WG5 committee that the collection of co-array features described in Working Draft J3/07-007r3 be incorporated into the language standard without significant refinements.

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 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 کاملCo-array Python: A Parallel Extension to the Python Language
A parallel extension to the Python language is introduced that is modeled after the Co-Array Fortran extensions to Fortran 95. A new Python module, CoArray, has been developed to provide co-array syntax that allows a Python programmer to address co-array data on a remote processor. An example of Jacobi iteration using the CoArray module is shown and corresponding performance results are presented.
متن کاملCo-Array Fortran Experiences with Finite Differencing Methods∗
Partial differential equations are used to describe physical phenomena in many science and engineering fields. Finite differencing methods map these continuous equations into discrete space so that they may be solved on computers. Co-Array Fortran provides the means for implementing such solution methods in parallel processing computing environments. In this report we describe our experiences w...
متن کاملADAPTing Fortran 90 Array Programs for Distributed Memory Architectures
We describe a system that we are developing, whose purpose is to automatically transform data parallel Fortran 90 programs for execution on MIMD distributed memory architectures. The system is called ADAPT (for`Array Distribution Automatic Parallelisation Tool'). Programs for the system should make full use of the array features of Fortran 90, as parallelism is automatically extracted from the ...
