hybrid/evolutionary: MPI+ ___ ?
- MPI for inter-node prog, since # notes and inter-node concerns not expected to change dramatically
  - support for hybrid programming/interoperability
  - purer one-sided communications; active messages
  - asynchronous collectives

- something else for intra-node
  1. OpenMP
    - introduction of locality-oriented concepts?
    - efforts in OpenMP 3.0 ?

- 1. PGAS languages
    - already support a notation of locality in a shared namespace
    - UPC/CAF need to relax strictly SPMD execution model

unified/holistic: __ ?
- a single notation for inter- and intra-node programming?
