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

Hello all,

after compiling itk under windows with visual studio 10 (32 bit), with
fftw3 enhancement and the fftconv wrapper proposed by Gaëtan Lehman, I
found some funny things in my code :

under windows I have to face memory limitation that are rather drastic : I
cannot process an image bigger than  250*250*250 double itkImage with a
fourier transform,

under linux there is no problem at all (I can go up to 500*500*500 double
itkImage), itk can allocate whatever is needed (eventually it falls on
swap).

My question is : how to overcome this ? Should I go for a windows 7 64 bit
os ? Does this will REALLY resolve this problem ? Is there a clever (or
usual) workaround that I am not aware of ?

Thanks in advance for your time !

Regards,
de Vieilleville François
