Reconfigurable object consistency model for distributed shared memory

Abstract

The consistency models are responsible for managing the state of shared data for the applications of a distributed shared memory (DSM) systems. The already proposed consistency models are inflexible and cannot adapt to the workload and environments characteristics. So, they cannot achieve the best performance for the workloads and environments in all the cases. In this work, we propose, present and analyze a reconfigurable consistency model (ROCoM -Reconfigurable Object Consistency Model) for object based DSMs. ROCoM behavior was represented using a reconfigurable algorithm (RA) and its analysis was made using a simulation tool. Our results show that ROCoM, on average, had 34% (upper bound) better performance than other ones. © Springer-Verlag Berlin Heidelberg 2005.
