Richard Gooch <rgooch@atnf.csiro.au>:
: A good RT system would allow you to put it all on one computer and
: data would not need to be shipped around (you'd use threads or
: SHM). However, on such a system you will have a considerable number of
: (low priority) user processes sitting on the run queue (the latest
: generation of data reduction software is very modular and has lots of
: processes doing different parts of the work). A dozen processes is not
: unreasonable.

A dozen CPU bound processes? You've seen this? Or you think it would
happen? In every system like this that I've seen (and I've seen a bunch),
people eventually weed it down to a CPU bound process/CPU, maybe two.
The throughput of the system slows down otherwise. This is /especially/
true on RT applications - any inefficiency can't be tolerated.
