CONSISTENCY MODELS IN DISTRIBUTED SHARED MEMORY SYSTEMS?

A Distributed Shared Memory (DSM) combines the advantage of shared memory parallel computer and distributed system. The value of distributed shared memory depends upon the performance of Memory Consistency Model. The consistency model is responsible for managing the state of shared data for distributed shared memory systems. Lots of consistency model defined by a wide variety of source including architecture system, application programmer etc. In this paper, we explore shared memory, memory consistency models and mechanisms for differentiating memory operations.
