Co-arrays in the next Fortran Standard

2007
The WG 5 committee, at its meeting in Delft, May 2005, decided to include co-arrays in the next Fortran Standard. A Fortran program containing co-arrays is interpreted as if it were replicated a fixed number of times and all copies were executed asynchronously. Each copy has its own set of data objects and is called an image.

Unified analysis of co-array interpolation for direction-of-arrival estimation

2017 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2017
This paper considers the problem of co-array interpolation for direction-of-arrival (DOA) estimation with sparse nonuniform arrays. By utilizing the much longer difference co-array associated with these arrays, it is possible to perform DOA estimation of more sources than sensors.

Performance analysis of ESPRIT-Type algorithms for co-array structures

2017 IEEE 7th International Workshop on Computational Advances in Multi-Sensor Adaptive Processing (CAMSAP), 2017
In the recent field of co-array signal processing, sparse linear arrays are processed to form a virtual uniform linear array (ULA), termed co-array, that allows to resolve more sources than physical sensors. The extra degrees of freedom (DOFs) are leveraged by the assumption that the signals are uncorrelated, which requires a large sample size. In this

Co-prime array processing with sum and difference co-array

2015 49th Asilomar Conference on Signals, Systems and Computers, 2015
Among various sparse-array techniques, co-prime array is found to be more attractive because of its high efficiency and simplicity. In this paper, we propose a scheme that can exploit both sum and difference co-arrays to form a larger size of continuous virtual array while keeping the conventional co-prime array configuration.

Rationale for co-arrays in Fortran 2008

ACM SIGPLAN Fortran Forum, 2007
This paper explains some of the technical decisions made during the incorporation of co-arrays in Fortran 2008. Familiarity with John Reid's summary of co-arrays [R07] is assumed. This document is by no means exhaustive: It is a selection of issues from my recollection.

Co-array Python: A Parallel Extension to the Python Language

2004
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.

Parallel Programming with Co-arrays

2018
Parallel Programming with Co-Arrays describes the basic techniques used to design parallel algorithms for high-performance, scientific computing. It is intended for upper-level undergraduate students and graduate students who need to develop parallel codes with little or no previous introduction to parallel computing. It is also intended as a reference

Writing a multigrid solver using co-array fortran

1998
Co-Array Fortran, known previously as F−-, is an extension to Fortran 95 that combines elegance of expression with simplicity of implementation to give an efficient parallel programming language. We illustrate its power and efficiency with a multigrid solver for Poisson’s equation in three dimensions.

Co-array Fortran for Full and Sparse Matrices

2002
Co-array Fortran (Numrich and Reid 1998), abbreviated to CAF, is an extension of Fortran 90/95 for parallel programming that has been designed to be easy both for the compiler writer to implement and for the programmer to write and understand. It offers the prospect of clear and efficient parallel programming on homogeneous parallel systems.Each ...
