  • System and method for determining a process's actual working set and relating same to high level data structures
    Patent number: 5721917
    Abstract: An interactive, information logging and processing tool that provides information regarding a process's data structure utilization to reduce the working set of a process's dynamically allocated memory. The actual working set (AWS) determinant determines which portions of the dynamically-allocated pages, referred to as the process's virtual memory (VM) working set (VWS) are actually used. It then determines the actual working set of a dynamically allocated memory for a given benchmark. The basic approach of the AWS determinator is to observe which data structures cause page faults when the targeted process is severely thrashing. AWS determinator includes a data logger and a data analyzer.
