[Radiance-general] compiling Radiance 64-bit?

[Rob Guglielmetti]

Hello Radiance Users, Abusers and Confusers,

Please excuse my ignorance, but assuming one has a computer with a 
64-bit operating system (SuSe Linux) installed, can Radiance be compiled 
as a 64-bit application?  And if so, has anyone done it?  What's the 
makefile look like?  The reason I ask is that I'm looking at possibly 
building up a quad system (two dual-core cpus) and with the potential 
for four jobs running at once I think I need more addressable memory.  
As I understand it, with a 32-bit application you're limited to 4GB 
total, whereas with everything 64-bit, the system can address 8GB of 
RAM.  Since I rarely see jobs needing more than 2GB of RAM, I figure 
having 8GB available for a maximum of four jobs means no job would 
likely ever run out of RAM and start paging.  Maybe my first question 
should really be: am I thinking about this correctly?  =8-) 

Any input appreciated.  (I think I need coffee.)
