To set the heap memory to be used by a java program export the _JAVA_OPTIONS variable in the environment the program runs in - either on the command line, in a personal module, or in a job script. For example,
export _JAVA_OPTIONS="-Xms1g -Xmx4g"
will set Java heap memory usage to a minimum of 1g and a maximum of 4g. Please note that _JAVA_OPTIONS environment variable overrides the respective command-line arguments. For example, the above '_JAVA_OPTIONS' variable will override the '-Xmx500m' argument in
java -Xmx500m -jar someprogram.jar....
