Distributing rendering in chunks is rather crude, it is far better to write 
code that spreads computational loops and recursion etc. over as many 
threads as possible and then run the code on a MOSIX cluster where the 
operating system automatically distributes the threads among the available 
CPUs.

I mentioned this recently as but got zero replies.
:o(

I wanted to know if anyone has profiled POVRay to see where all the work 
was being done so that I could use the Cilk system to create a massively 
threaded version of POVRay that could run across a MOSIX cluster.

There is also a PVM version of POV but last time I looked it was based on 
an old version. I was hoping to look at the 3.5 source code some time soon 
and use that as a basis for a Cilk-MOSIX_Povray variant.

This would have to be the Linux/Unix version as MOSIX is not an option for 
a closed source operating system such as Windows, unless Microsoft make a 
MOSIX version of Windows XP (XS?) :o)  available.
