(Thanks Andrew Dalke. You remember it after all these years!) Jonathan, actually, even in that set, OpenAtom is not a particle code. Its a quantum chemistry code where each electronic state is represented often by a large 3D array spread over processors.. For more recent examples of representative miniApps, see http://charmplusplus.org/benchmarks/ or our upcoming workshop (sorry for the plug: http://charm.cs.illinois.edu/charmWorkshop

The broader article deserves further though, and I hope to find time to respond. But it is clear that raising the level of abstraction beyond MPI is necessary.
