A Co-array Fortran program is interpreted as if it were replicated a number of times and all copies were executed asynchronously. Each copy has its own set of data objects and is termed an
image. The array syntax of Fortran 95 is extended with additional trailing subscripts in square brackets to provide a concise representation of references to data that is spread across images.
The ISO Fortran Committee decided in May 2005 to include co-arrays in the next revision of the Fortran standard (2008).
The only open source compiler which implements the core Co-array Fortran standard for Linux architectures is
G95G95 is a free, portable, open source Fortran 95 compiler. It implements the Fortran 95 standard, part of the Fortran 2003 standard and some old and new extensions including proposed features for the Fortran 2008 standard like Co-array Fortran....
