VS Aero and VS 1000 ... spend over half their time writing out answers

[David Hough]

This is amazing.  Presumably the machines in questions
are supercomputers.  Presumably the data is not going to intermediate
temporary files; otherwise unformatted I/O would be used.
What happens to the reams of formatted output that these programs produce?
Even half a minute's time on any Cray is a lot of formatted output.
If it's being read by another computer, it's hard to see how anything
but a Cray could keep up - which suggests unformatted I/O again.
