The stats are in from www.blastwave.org on the initial build of a 64-bit ver
of POV-Ray 3.50c as a 64-bit binary with 64-bit libraries :
bash-2.03$ file povray_64bit
povray_64bit: ELF 64-bit MSB executable SPARCV9 Version 1, UltraSPARC1
Extensions Required, dynamically linked, stripped
bash-2.03$ file povray_sun
povray_sun: ELF 32-bit MSB executable SPARC32PLUS Version 1, V8+ Required,
UltraSPARC1 Extensions Required, dynamically linked, not stripped

the 64-bit version was a little slower ...

yes .. but a 5% difference is no big deal in speed for the ability to use
more ram. Sun servers, unlike the intel world, commonly have greater than 4Gb
of RAM and 16Gb to 32Gb of RAM is no big deal out of the box for a V880 with
eight CPUs. I plan to test POV-Ray with a large render on such a machine. At
the moment I am choked back to 8Gb of RAM in a 280R with dual 900MHz
processors. What I need now is a scene file with a LOT of very simple
objects, like spheres and cubes, that will chew up all that RAM. Should make
for a large test.
