Like the Cray Y-MP or Cray 3?  IMHO, if you wish to be a player in the
supercomputing game, you'll have to consider systems which don't support
virtual memory.  How about enormously parallel machines with a large
number of processors but a small amount of physical memory per
processor?  I suspect that non-virtual memory machines will be around
for much longer than any of us care to think about.
