To cater to the growing needs of computer applications, memory managers have to become smarter to minimize the cost of retrieving data from relatively much slower magnetic discs. Memory allocators determine which pages of virtual memory to store at various levels of memory hierarchy. This research paper utilizes the concept of reference locality to address the issue of page faults, describes how to measure page-level locality and presents the results of experiments on various allocator algorithms. Characteristics of allocator design are evaluated and directions for further research are...
