Architectural optimizations to advanced distributed simulation

Abstract

Current DoD mechanisms to support distributed simulations have reached their limits in terms of size and fidelity. Several projects are underway to improve the state of the art in the DoD, defining a new class of distributed simulation: Advanced Distributed Simulation (ADS). This paper presents an architectural view of the problem area, i.e. identifying the conceptual objects in an ADS system, and describing their responsibilities and interactions. Classes of data transmission optimizations are identified and discussed in terms of scalability, flexibility, and current research efforts.

A load-sharing architecture for high performance optimistic simulations on multi-core machines

“…As for HLA-based simulation platforms (see, e.g., [9]), multi-threading has been used to implement non-blocking interoperability services across federations of simulators. The strongest difference from our approach is that multi-threading has been used to implement sector-specific functionalities, while we use it as a means to overtake differentiated operations (including event processing), depending on dynamical variations of the application level workload.…”
