Does anyone have a collection of performance (timing) data based 
on running a raytracer (preferablly a publicly available raytracer, 
e.g. mtv or qrt) on various machines? 

In specific, I am interested in the answer(s) to the following question:

	To make a ray-tracing based animation film, which commercial
	machine(s) (excluding in-house hardware) can give the shortest
	computation time with moderate effort in optimization.

For example, my experience indicates that mtv runs on a
Cray Y-MP (-hintrinsic,o_level3) ~2.6x than on a PMAX, is this
(Cray time) the fastest turn-around one can expect?
Will a Connection Machine do better than this? What about an Intel iPSC?
The Meiko transputer array? Silicon Graphics's Power series?

Any info. is appreicated.
