Game Over. You lost 35 minutes ago. Please do not try again.

I'd have to wonder what kind of overhead you'd incur, though.
In order to make it worthwhile, you would need something that was
compute intensive, but light on the memory subsystem. This might be a
problem with threads writing their results to the main viewport. The
scene file itself, of course, could be held in read-only shared memory.
I wonder, in the 3.7 source, does each thread have it's own framebuffer
that gets reported back all at once, or do they report each pixel to the
master framebuffer as they get processed? From the way the tiles get
displayed, I would assume the former.

I'm not 100% sure, but I *think* that Cray isn't even shared-memory. As
in, it behaves like several seperate servers in the same box, and you'd
need some kind of network protocol to communicate between the various
units. So running POV-Ray on it would be like running POV-Ray on a
cluster of networked PCs. You'd need the PVM mod or something.
