A Resource Management Framework for Priority-Based Physical-Memory Allocation

Cheung, K. and Heiser, G.

New multitasking operating systems support scheduling priorities in order to ensure that processor time is allocated to important or time-critical processes in preference to less important ones. Ideally this would prevent a low-priority process from slowing the execution of a high-priority one. In practice, strict prioritisation is underminded by a lack of suitable allocation policy for resources other than CPU time. For example, a low priority process may degrade the execution speed of a high-priority process by competing with it for physical memory. We present the design of a flexible resource management framework which prioritises memory allocation, and examine a prototype implementation for the Mungi single-address-space operating system.
