ABSTRACT:
A system for managing execution of a computer program. A domain array is used to reduce the overhead associated with managing multiple instances of a computer program. A portion of virtual address space is reserved for multiple instances of the computer program, each instance having virtual address space reserved for program code and data. The virtual addresses of the program code for the plurality of instances are mapped to shared physical address space having the executable code. The virtual addresses of data for the plurality of instances are mapped to respective dedicated portions of physical address space having data for the plurality of instances.
