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. The data logger ensures that a consistent benchmark is achieved in order to obtain the most accurate results, increases the number and granularity of heap page faults for the target process to enable the page fault mechanism of the processor to count the number of times the associated data structure is accessed, and log all heap page faults and transactions. The data analyzer is an interactive, information processing tool that efficiently process the large amounts of data logged by the data logger …
