Static allocation must be done using a scheduler. The system will only 
enforce the maximum amount of memory usable per process. And if a 
process goes over this limit it will be killed.

If you want system-level enforcement of resource allocations, you will 
have to use a modified version of Torque with support for CGROUPS.
