Oh, there's no thought that MPI would be even remotely appropriate here, however, if someone is looking for a dissertation or thesis topic <grin>?
Virtually all of my recent HPC has been essentially EP jobs submitted through PBS, with no need for MPI (yet).

    MPI is not likely the best programming model at present for such a 
    scenario, because fault tolerance is not great. However, there are 
    people running many loosely coupled parallel programs on clusters 
    because the computational capacity and storage mechanisms make it 
    convenient, even if the interconnect is heavily underutilized. Thus it 
    is more a matter of finding appropriate workloads. Many data centers 
    often have idle capacity, appropriate preferential pricing policies can 
    make use of this - not something HPC community typically considers, but 
    something cloud and grid computing people have been working on for a 
    while. Comet computer at SDSC is targetting some of these workloads.
