I wonder if POV-Ray 3.7 has ever been tested with that many rendering
threads, and whether it would cope.

I presume the machine is essentially a cluster, so not much luck there:
You'll have a huge number of dual- or quad-core machines to crunch away
at a single frame of an animation each, but that'll be about it.
Unfortunately, although 3.7 is SMP-ready, it isn't "network-ready" yet.

I think there's some support in linux to make a cluster look like a
bunch of local processors.

If there isn't, Debian have a hacked PVM version of POV-Ray...

Uh.. yeah, POV-Ray was designed to be portable.

Well, since apparently this puppy is running Linux (which POV-Ray
already supports) and an AMD64 CPU (which POV-Ray also supports), sure,
it's pretty trivial. But if you wanted to do this on some OS where
libPNG isn't available (for example)...

POV-Ray doesn't support any processors. Compilers do.

POV-Ray can be compiled without pnglib.

Oh, right. I didn't know that.
[Or rather, I didn't know it's easy to enable or disable - which I
presume is what you meant.]

If there really is, then be prepared for some serious performance
degradation, at least with some features (most notably radiosity,
probably also photons, and a few "smaller" ones like crackle patterns)
which rely on shared memory.
