摘要
A method and directory system that recognizes and represents the subset of sharing patterns present in an application is provided. As used herein, the term sharing pattern refers to a group of processors accessing a single memory location in an application. The sharing pattern is decoupled from each cache line and held in a separate directory table. The sharing pattern of a cache block is the bit vector representing the processors that share the block. Multiple cache lines that have the same sharing pattern point to a common entry in the directory table. In addition, when the table capacity is exceeded, patterns that are similar to each other are dynamically collated into a single entry.
