I think coarrays have a lot of promise; it's less ambitious than the single unified picture of a program that Chapel or UPC has, but maybe that's a feature, not a bug, for incrementally changing how we do things. One problem has been that implementations of coarrays depended on MPI-2 features which were brittle and not super optimized (because they weren't widely used); but with MPI-3s RMA, or gasnet (which I think gfortran is starting to use?) it could start being more practical for production use. |
