Clarification: Fortran’s parallel programming model is agnostic about the
memory architecture. The 2008 standard made Fortran the only widely used
language with a parallel programming model that works in shared- or
distributed-memory systems. I’ve seen papers in which people have run coarray
Fortran (CAF) on over 100,000 cores with impressive results.
As a side note, the draft 2015 standard makes Fortran also the only widely used
language with support for fault tolerance, which makes Alessandro’s and Andre’s
work on failed-image support truly exciting and I’m amazed that there already
exists an MPI limitation with some support for what is needed to support
failed-image detection.
