Consistency Model and Synchronization Primitives in SDSMS

Abstract

Abstract —consistency model like Strict Consistency, Sequential Consistency, Processor Consistency, Weak Consistency etc. Then the techniques for implementing distributed shared memory Systems and Synchronization Primitives in Software Distributed Shared Memory Systems are discussed. The analysis involves the performance measurement of the protocol concerned that is Multiple Writer Protocol. Each protocol has pros and cons. So, the problems that are associated with each protocol is discussed and other related things are explored. Keywords — Distributed System, Single owner protocol, Multiple owner protocolI. I NTRODUCTION distributed system is an application that executes a collection of protocols to coordinate the actions of multiple processes on a network, such that all components cooperate together to perform a single or small set of related tasks. II. M EMORY C ONSISTENCY M ODEL A memory consistency model is a contract between programmers and shared memory which specifies how the memory operations of a program will be executed. Computer scientists have proposed different memory models to enhance distributed shared memory systems. In this section, we will give an introduction to those memory models and some terminology used in this paper.
