  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.
