Mm. I've quite often run MPI locally (it's nice for multicore scientific computing on Python), but I had no idea that OpenMP had cluster implementations. Thanks for the tip.

Intel has been selling one, I think there are others too. OpenMP has a flush pragma for synchronizing shared variables. This means that OpenMP is not restricted to shared memory hardware. A "pragma omp flush" can just as well invoke some IPC mechanism, even network communication. Sturla
