Optimistic Synchronization of Parallel Simulations in Cloud Computing Environments

Cloud computing offers the potential to make parallel discrete event simulation capabilities more widely accessible to users who are not experts in this technology and do not have ready access to high performance computing equipment. Services hosted within the ldquocloudrdquo can potentially incur processing delays due to load sharing among other active services, and can cause optimistic simulation protocols to perform poorly. This paper proposes a mechanism termed the Time Warp Straggler Message Identification Protocol (TW-SMIP) to address optimistic synchronization and performance issues associated with executing parallel discrete event simulation in cloud computing environments.
