Note on 32 bit even though the system may let you get to 3gb of memory seen
Your addressable memory space per process will be limited to around 1.8gb on a 32bit system Gordon -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Robert Balfour Sent: Thursday, November 29, 2007 7:03 AM To: OpenSceneGraph Users Subject: Re: [osg-users] 64-bit OSG Daniel Holz wrote: > > hi, > > what are the benefits of using a 64bit build of osg. as far as i know > at least the floating point precision is not higher than with 32bit, > or am i wrong? > My issue is the 32-bit 4GB system address space limitation, which actually will limit you to 3GB of usable CPU memory (even if you have 4x1GB memory cards) if you start using the new 1GB Nvidia cards (that will be mapped into device address space). Of course you can start paging the scenegraph, but I also have a handful of data caches that can grow pretty big under some conditions, so a larger 64-bit address space should at a minimum immediately get me access to the full 4GB of physical CPU memory for starters. Or maybe my 64-bit expectations are too high? Bob. -- Robert E. Balfour, Ph.D. Exec.
