Re: Increasing EASI processing performance?

Hi Jonas, if your PC is dual or quad core you should split the script into multiple parts. Processing 50% of the MODIS tiles in one dir. and 50% in another dir.. Also using two different HDiscs is useful for these two routines than. That will utilise the multi-core character of your system much better. Geomatica is not scaling its CPU-load to multiple CPUs so this might increase your processing speed.

Dear list

I am running 10.1.3 using a decent PC with XP, currently processing some 2800 MODIS tiles (each 2400x2400) using an simple EASI script (including FIMPORT, MODEL on and MOSAIC as main features). This takes around 48 hours (estimated time, process not ready yet) and I probably have to run it several times and for larger areas further on.

How do I speed this up?

I can increase priority of the EASI process in Task Manager/Processes but this hardy help as the main functions taking power are called upon during each iteration and hence are FIMPORT, MOSAIC  etc. restarted  during each iteration (for each MODIS tile).

Migrate to LINUX for better utilization of resources? Any recommendations on this?
