Title:
Modern Fortran, with emphasis on coarrays

Abstract:
Fortran is now 60 years old and has evolved steadily during this time. It
was the first computer language to be standardized (1966) and the standard
was revised in 1977, 1990, 1995, 2003, and 2008. A further revision is on
schedule for completion this year.

I have been a user of Fortran since the late 60s and have contributed many
Fortran codes to HSL (formerly the Harwell Subroutine Library). I have been
involved in Fortran standards since 1983, when I was asked to join the
committee because of the heavy investment in Fortran programmes by the UK
Atomic Energy Authority. I have continued ever since with the aim of
improving the language, despite the Numerical Analysis Group moving to the
Rutherford Appleton Laboratory in 1990.

Fortran has lost the dominant position it held in the 70s, but modern
Fortran is well used, particularly on supercomputers and is a very
different language, though old programs are still accepted and efficient
execution has been retained. I will give you my explanation of why it lost
its dominant position and quickly summarize the main changes in each of the
revisions.

My main objective is to give you an overview of Fortran 2008, paying
special attention to coarrays, which provide a particularly pleasant way to
perform parallel programming. I will also explain the main additional
features of Fortran 2018. It includes the ability to continue executing in
the presence of a small number failed processes, not unlikely when long
runs are made on huge numbers of processes.
