CAF (Coarray Fortran)
CAF is a parallel programming extension of the Fortran syntax that allows a programmer to view a single shared partitioned address space.
CAF is available on Edison and Cori via the Cray compilers.
To compile a CAF source file you must first swap the Cray compiler with the default compiler.
% module swap PrgEnv-intel PrgEnv-cray
Then compile the code like this:
% ftn -h caf -o CAFProg CAFProg.f
The "-h caf" option is needed on the cc command line.
