... oh, and by the way, that's "56 processes", not "56 processors";
looks like 64 cores to me. What a shame to have such a machine run idle...

No, but it runs that web-based unbiased renderer somebody posted the
other day... ;-)

I'm struggling to think of any kind of scene that would require more
than about 10MB of RAM.
Image textures? Photon maps? Radiosity? Sure, those might eat some RAM.
But the scene itself? I can't think of a way...

Believe me - you /can/ fill /any/ size of RAM with a suitable SDL script ;-)
A huge crowd of individually-posed people might also do the trick.
I concede though that anything SDL to fill 2 TB might take /some/ time
to parse :-P

The writing is so tiny...
(The again, it does say "64 core" in the URL. Assuming all of those are
physical cores and not hyperthreads.)
Obviously this is some kind of server. I can't imagine what the hell it
costs to buy something like this, or where you'd get it from.

2TB of SDL? Yeah, that's going to be I/O-limited or parse-time limited,
or both. ;-)
The only time I've ever filled RAM with POV-Ray is attempting to use
volume photons. Apparently this is impossible. (Or rather, it's
impossible with a 0.25GB laptop. Maybe with 8GB it could be almost
possible...)

OK, so I just took a look at our supplier's website. They list /one/
server which supports 16 physical processors. If each one had 4
independent cores, that would give you 64 cores. The server costs
which type of CPU it supports...
Going down to 8 CPUs... actually I see an Intel-branded rack-mount
this is going to be a Xeon server. (Doesn't say which generation.) If
they make 8-core Xeons, you could get 64 cores this way.
(4x the price.) That's /with/ 4x AMD Opterons installed though. (Opteron
8384, quad-core, 2.7 GHz.) Also comes with 32GB of RAM installed.
Suffice to say, this stuff is expensive...

Looks like an 8-core 2.9 GHz Xeon will set you back about $3,500 from
So the 8 CPUs cost more than the entire server. (!)

The scene that I am running just now uses just under 200 Meg of ram.
There is only one poser figure and two bits of clothing.

Clearly something has to go. The latter, preferably. ;)

Funny you should say that. ;-)
The experiment is to see if I can reproduce something I read in a book
many years ago. A woman was wearing a dress to a party. The material
became transparent in random patches.
I think that I have the basics working but I am having difficulty with
the random patches.
So before someone screams ON TOPIC I'll post a link to the animation in
povray.animations when I am ready for some help.
