Hi again,
with your help I've fix problem with "integer overflow" and now I get
correct results.
Also I clean up my code for reduce memory usage but problem with large
files is
remain. I have raster with size 11779*10663 and 5 bands. When I
calculate NDVI
on Linux box (2 Gb RAM, 2Gb swap, GDAL 1.6.3) all works fine and I get
correct
results.Peak memory consumption during this operation is 1900 Mb RAM and
300 Mb swap (monitored with htop).
When I run same code with same raster on Windows box (2 Gb RAM, swap
size is
selected by OS ~1.3 Gb, GDAL 1.6.3) I get MemoryError. Peak memory
consumption
during this operation is 600 Mb RAM and 700 Mb swap. I've try smaller
raster with size
8500*7600 pixels but get MemoryError too.
Hi,
I'll bet the problem is that you are hitting the normal 2GB user address
space in Windows.
Google for "/3GB" and you will find how to increase this to 3GB.
