Threading and PBS resources violation

Java uses the garbage collector and other techniques. This can increase the number of used processors which can violate the CPU limit set by scheduler. To avoid this you can:

• try to request more resources (eg. 4 more processors)
• run Java with some parameters, eg. java -XX:+UseSerialGC -XX:-BackgroundCompilation
