Abstract:

A memory management system for managing memory of a processing device and a corresponding method thereof. The system comprises a memory manager and a garbage collector. The memory manager is configured to allocate memory after dividing discrete units of memory into smaller units. The garbage collector is configured to organize a memory availability collection of free units of memory in the memory manager. The collection is ordered based on at least one of the amount of each of the discrete units available and the allocation age of the discrete units.

Abstract:

A method for managing memory usage in a computer system having a kernel and a kernel memory class. The method includes ascertaining a size of a base memory of the computer system, the base memory representing memory designated to be non-evacuable. The method also includes setting a size of the kernel memory class to be no larger than the size of the base memory. Requests for additional memory by a kernel process is evaluated at the evaluation stage and granted only if the additional memory, if granted, would not cause an amount of memory used by the kernel to exceed the size of the kernel memory class.
