Its LINPACK rating is probably relatively poor, as LINPACK doesn't quite fit
well in the "embarassingly parallel" category - if you split it across a million
nodes, you *do* have some cross-node communication that needs to happen - and
preferably *fast* (we're talking the kind of fast where they buy Infiniband
or Myrinet gear because gigabit ethernet isn't fast enough)....
