Any language supporting (current) OpenMP supports fork-join, tasking, SIMD specification, and offload, though you still want distributed memory, and overlapped communication and computation. Baking particular technology into a system isn't a good idea long-term, or even medium-term, unless you wait for the cycle of re-invention, like vector computing. (I don't know if Julia really does that.)
