Abstract :
Consistency is an important issue in Distributed Shared Memory (DSM) systems. These systems share a set of objects or virtual memory pages. The data sharing enables the applications in workloads to access the data concurrently. But, these concurrent accesses can generate some inconsistencies in the shared data state. The consistency models are responsible for managing consistency of shared data for the workloads. In this work, we propose, present and analyze a reconfigurable consistency model for object based DSMs. We called this consistency model ROCoM (Reconfigurable Object Consistency Model). ROCoM behavior was represented using a reconfigurable algorithm (RA) and it analysis was made using a simulation tool (ClusterSim - Cluster Simulation Tool). Our results show that ROCoM, on average, had 55% better performance than the other traditional consistency models.
