Modern Fortran's only parallel feature is coarrays, which operate at the whole program level.

DO CONCURRENT is a serial construct with an unspecified order of iterations, not a parallel construct. A DO CONCURRENT loop imposes requirements that allow an arbitrary order of iterations but which are not sufficient for safe parallelization.

How do you feel about Nvidia endorsing do concurrent migration to GPUs? Would that be classified as parallelization?
