Addressing the Problem of Cache Coherence in Multiprocessor Systems

Abstract

Computer systems (multi processors) need to avoid the cache coherence problem which has been solved by today's multiprocessors through implementing a cache coherence protocol. The cache coherence protocol affects the performance of a distributed memory-shared multiprocessor system. This paper discusses several different varieties of cache coherence protocols including advantages and disadvantages, the way they are organized, and some examples of systems that implement those protocols.
