Abstract
The large diffusion of multi-core machines has pushed the research in the field of Parallel Discrete Event Simulation (PDES) toward new programming paradigms, based on the exploitation of shared memory. On the opposite side, the advent of Cloud computing—and the possibility to group together many (low-cost) virtual machines to form a distributed memory cluster capable of hosting simulation applications—has raised the need to bridge shared memory programming and seamless distributed execution. In this article, we present the design of a distributed middleware that transparently allows a PDES application coded for shared memory systems to run on clusters of (Cloud) resources. Our middleware is based on a synchronization protocol called Event and Cross State Synchronization. It allows cross-simulation-object access by event handlers, thus representing a powerful tool for the development of various types of PDES applications. We also provide data for an experimental assessment of our middleware architecture, which has been integrated into the open source ROOT-Sim speculative PDES platform.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
