Computer resource management system

摘要

A system and method for managing scarce computer system memory resources has three aspects. A first aspect allows large data structures to be replaced by a pointer that causes an intentional fault to occur. The fault is trapped, and the invention interposes the required data. A second aspect associates data structures with both the task and the module that own the structure. The structure can be eliminated from memory when both the owning task and the owning module have terminated. A third aspect utilizes swapping techniques to maintain multiple local data areas for multiple tasks. In conjunction, the three aspects of the invention provide improved resource availability and substantially unimpaired system performance
