And unfortunately that goes very deep and does certainly not stop at the
operating system. Once you deart from a von-Neuman architecture, many
respected truths are no longer applicable. Take the well-known suggestion
that a binary chop is the fastest way to serch an ordered list. If you have
two processors (and a few more performance parameters ...) you will find
the fastest search splits the population at the 62/38 % rather than at 50/50.
Once you design hardware that requires people to redefine and rethink
their problems before they can use of it you have some selling to do.
