Method and system for improving cache performance in a multiprocessor computer

摘要

A method and system for allocating and storing data to a cache memory in each processor in a multiprocessor computer system. Data structures in main memory are partitioned into substructures that are classified as either exclusive substructures or sharing substructures. The exclusive substructures are cached exclusively by a specified processor, and the sharing substructures are cached by specified groups of processors in the multiprocessor computer. This classified partitioning results in an improved cache hit ratio compared to standard caching schemes, which improvement increases with the number of processors in the multiprocessor computer.
