Not even the subway, but the bus:-) Currently just building the application on my laptop for prototyping. Will eventually move to a win-only commodity boxes in 1 lan, or RHEL boxes in the long term, Unfortunately not possible to mix both.
The ideal solution would be some hybrid of openmp + openmpi but single box shared-memory openmpi multiprocess is not necessarily worse than a single process multithread openmp. '-mca btl sm,self' indeed didn't work, Ralph, please let me know if testing required.

No network connection, yet OpenMPI is still operational in a standalone insular machine. IMHO, MM made a good case for his 'commuter MPI'. :) Times change, I would never have thought that people are doing parallel programming and HPC in the subway.
