[Insight-users] Fwd: itk allocation limitation on a winXP 32 bit system

[Juan Vidal]

I got an error when sending this message, sorry if it is posted twice.


There is also a trick that you could use with Windows XP: 4GT. The bottom
line is that enabling this feature, you can let a process use up to 3GB of
main memory (default limit is 2GB per process in windows xp 32 bits). I
enabled this feature for a memory-intensive itk app that I wrote some time
ago, and it worked fine.

Hello all,
