Abstract-In this paper, we describe the design and analysis of a scalable architecture suitable for large-scale distributed shared memory (DSM) systems. The approach is based on an interconnect technology which combines optical components and a novel architecture design. In DSM systems, numerous shared memory transactions such as requests, responses and acknowledgment messages propagate simultaneously in the network. As the network size increases, network contention results in increasing the critical remote memory access latency, which significantly penalizes the performance of DSM systems. In our proposed architecture called reconfigurable and scalable all-photonic interconnect for distributed-shared memory (RAPID), we provide high connectivity by maximizing the channel availability for remote communication to reduce the critical remote latency. RAPID provides fast and efficient unicast, multicast and broadcast capabilities using a combination of aggressively designed wavelength division multiplexing (WDM), time division multiplexing (TDM), and space division multiplexing (SDM) techniques. RAPID is wavelength-routed, permitting the same limited set of wavelength to be reused among all processors. We evaluated RAPID based on network characteristics, power budget criteria, and by simulation using synthetic traffic workloads and compared it against other networks such as electrical ring, torus, mesh, and hypercube networks. We found that RAPID outperforms all networks and still provides good performance as the network is scaled to very large numbers.Index Terms-Cache coherence, distributed shared memory, optical interconnects, scalable optical networks.

Executive SummaryThis document provides general guidance designed to help the U.S. Department of Homeland Security (DHS) Program Managers and other executives inside and outside of DHS. It is intended to provide useful information that may help personnel better understand the technologies used to maintain and support homeland security modeling and simulation (M&S) applications. It is also intended to help the relevant professional community in developing better technical specifications for homeland security modeling and simulation (M&S) applications. Contractors outside of DHS typically develop homeland security M&S applications. Often the M&S applications that are developed today are difficult to extend for new purposes, to integrate with other software systems, or to be used by persons other than the original developer or development team. Slight changes to a model or scenario may require major changes to a system and significant cost to the sponsor.

Abstract-In tactical networks, nodes move according to tactical maneuvers and network partitions occur frequently. To mitigate this problem, data replication is commonly used to increase data availability and reduce data access delay. However, different tactical maneuvers lead to different node mobility models, which affect the performance of data replication schemes. In this paper, we comprehensively study the data replication problem in mobile tactical networks. We propose a new intra-group data replication scheme and extensively quantify the effects of mobility on different inter-group data replication schemes from various perspectives. The study is based on several metrics, which include the average access delay and data availability, and the temporal and spatial analysis of these values. Through extensive experiments, we study the effects of three typical mobility models in tactical networks on data replication, and identify the most suitable data replication schemes under various mobility models.
