Dear all,
I have a script, which calculates the ndvi in parallel on the server with 8 cores (OS is Debian GNU/Linux 6.0with Linux Kernel 2.6.32-5).
The experiments show that the images with the sizes up 500 MB successfully run on all 2 to 8 cores, but in case of the 1GB image size when I run the script on 5 cores I receive the following error:
“Gateway time-out, gateway didn’t recieve a timely responce from the upstream server or application”
Could you pls. let me know how to check and find out the reason (memory, HDD, CPU)?
Regards
Albert Saribekyan.

This is not a GRASS GIS message, you need to tell more what your
upstream server could be.
