Shared Memory Architecture and Explored Alternatives for Interoperability
Abstract
The Air Combat Environment Test & Evaluation Facility (ACETEF) is a major component of the Naval Air Systems Command (NAVAIR) Integrated Battlespace Simulation and Test (IBST) Department. The IBST Department is a collection of geographically distributed yet integrated test facilities and many diverse activities all designed to provide effective, affordable and repeatable test & evaluation (T&E) capabilities for a variety of naval aircraft, weapon systems, and other platforms. IBST includes facilities in both the Naval Air Warfare Center Weapons Division (NAWCWD) and the Naval Air Warfare Center Aircraft Division (NAWCAD). When the operating paradigm is "Simulate-Stimulate-Analyze & Fix-Fly," real-time, concurrent computing is going to be the order of the day. The ability to combine interoperability with concurrency both defines and distinguishes ACETEF and its stakeholders. As new systems are conceived to address modern warfighting doctrine, the need for applying this paradigm along the entire life-cycle spectrum from drawing board to operational support of these systems puts ACETEF's capabilities in the spotlight. ACETEF's concurrency model is not merely about shared memory, but rather the combination of elemental entity data and event transactions, whose interchange fit a shared memory model reasonably efficiently, combined with the effective stimulus-decision-response interaction between the external world and reflected entities in a virtual Joint Integrated Mission Model (JIMM) world. While the learning curve for this approach can be steep, it has successfully supported environments with thousands of entities.
