2.3. Hardware and Memory Requirements

The ICOL+ processor is a rather complex tool and requires extensive memory resources to work properly:

Usage of an up-to-date computer with at least 4GB RAM is strongly recommended. On less powerful machines, various kinds of failures may occur.
The standard BEAM/Visat VM options are not sufficient for ICOL+: In the 'bin' folder of the BEAM 4.10.x installation, edit the file 'visat.vmoptions' and change the 'Xmx' parameter (maximum Java heap space) from 1024M to at least 3000M. Restart BEAM to enable these new settings.
