Hi Robert,
Thank you for your quick reply.
I haven't changed the dimension, I'm still in 2D. And it's working fine
for me when size[0] * size[1] is less than 2 GB but not when it's more
than 3-4 GB :-(. So if you can try to make it work with a size of 5 GB
on your configuration, it would be really good / helpful!
Regards,
Florian
