It sure would be nice if software could be partitioned in an efficient
manner, including considerations of interconnect topology, with a
compiler flag. Alas, this we must still do ourselves.

This is a strange sentiment to be displaying on this list, if I may say
so. Beowulfers sit further out on the frontier so they can derive more
performance from their hardware budgets. The consequence of this is
additional development time, application complexity, and sometimes
hardware specificity.
