[Opensim-dev] General status of OpenSim on 64 bit Linux Architecture

[Mike Dickson]

It doesn't take alot of "tricks" to use beyond 3.5GB of memory with a 32
bit OS.  The PAE kernel will handle it. I have one system with 24GB
that's 32bit (for othe reasons).  I've also run OpenSIm 64bit fine
recently so I think either approach is feasible.  If I was starting from
scratch with a system with lots of memory I'd probably do 64bit...
