[RC5] dnet processing power?

top500.org has a widely used algorithm for
comparing across platforms, but again, it is
based on high-level language compilers 
translating mathematic operations into processor
ops--very different on each machine.


------------------------------------------------
A crude comparison is available at
http://n0cgi.distributed.net/statistics/
stats.html.  This puts d.net at
about the 20 TFLOP mark.

All of Dennis' comments regarding the accuracy of 
this figure apply.
