It did not make it into F2003 but:
[13:50] < toon> pinskia: No but it still stands a chance for F2008

[Bug fortran/18918] Eventually support the co-array f95 extension in gfortran

[burnus at gcc dot gnu dot org]

------- Comment #8 from burnus at gcc dot gnu dot org  2007-10-14 17:46 -------
For UPC (Unified Parallel C) - the C variant of something like Co-arrays - has
been implemented for GCC 4.0.x, see: http://www.intrepid.com/upc.html
I don't know whether they have signed a contract with the FSF or whether it
helps with implementing it.

Otherwise, one can use the OpenMP backend for shared-memory systems; for
distributed memory, one could either generate MPI 2 code directly or use - as
intrepid's gcc - Berkeley's GASNet library, http://gasnet.cs.berkeley.edu/.

Regarding the status: Co-arrays are one of the few remaining bigger changes
planned for Fortran 2003; see http://www.nag.co.uk/sc22wg5/, esp. on that page:
- "Co-arrays in the next Fortran Standard"
- "Rationale for co-arrays in Fortran 2008"
- Current draft: http://www.j3-fortran.org/doc/standing/links/007.pdf
- Timetable: ftp://ftp.nag.co.uk/sc22wg5/N1651-N1700/N1693.txt
2007-12 - first working draft; 2008-04 WG5 approval of draft; 2009-07 final CD
submitted.

[Bug fortran/18918] Eventually support Fortran 2008's coarrays [co-arrays]

[burnus at gcc dot gnu dot org]

------- Comment #9 from burnus at gcc dot gnu dot org  2008-03-25 18:49 -------
Fortran 2008 is now a Candidate Draft; the latest draft and a brand new Coarray
introduction is now also available. Links, see bottom of:
http://gcc.gnu.org/wiki/GFortranStandards

What I want to mention: The implementation should be such that OpenMP can be
combined with coarrays. Or, if this is too difficult, -fopenmp should be
rejected with an error when coarrays are found in th Fortran file.

Someone (Toon?) mentioned a plan to make the GOMP backend infrastructure usable
for shared memory. I also found the following paper: "Prototyping the automatic
generation of MPI code from OpenMP programs in GCC" at
http://gcc.gnu.org/wiki/GROW-2009

Assign to me - I'm working on it to get single-image support working. Real PGAS
support will follow later and not necessarily by me.

First patches for (single-image) Coarray support, see

about half of the work is already done & approved for committal when the 4.6

First committal (which went to the wrong PR: PR 39997):
URL: http://gcc.gnu.org/viewcvs?root=gcc&view=rev&rev=158008

Added: single-image support for CRITICAL block, SYNC MEMORY/IMAGES/ALL, and
num_images() (which is constantly one).

[Bug fortran/18918] Eventually support the co-array f95 extension in gfortran

[jblomqvi at cc dot hut dot fi]

------- Additional Comments From jblomqvi at cc dot hut dot fi  2005-06-20 07:25 -------
Apparently it has been decided that co-arrays will be included in the next
revision of the Fortran standard.  See  http://www.nag.co.uk/sc22wg5/  and
ftp://ftp.nag.co.uk/sc22wg5/N1601-N1650/N1639.txt

Something to think about once F2003 support is completed. ;-)

You might want to check out the "global arrays" toolkit at
http://www.emsl.pnl.gov/docs/global/ga.html

GA implements the same programming model as Co-Array Fortran, but it's a
library, so any standard F95 compiler should do.

I agree, but figured it was worth filing away for the future.  Here's another
doc from cray, the link to which I couldn't find earlier:
http://www.cray.com/cgi-bin/swpubs/craydoc30/craydoc.cgi?frames=1&html=toc_view&pub=S-3694-53
(Chapter 9 of the third volume of their Fortran Language Reference Manual
describes Cray co-arrays.)
NB: It's not Numrich and Reid, but I figure I'll note it here for future
reference just in case (in case, for example, there were an implementation
divergence in the future)

This might be interesting, even though I think it's far out of reach currently.

The available information on it is, admittedly, a bit dispersed, but I think
http://www.co-array.org/caf_def.htm might be close enough to what you are
looking for.
