Title: PET FMS demos, including Parallel Minefield Simulation (CMS), JWORB (Java Web Object Broker) based RTI and WebHLA Infrastructure Description: We present a set of demonstrations of PET FMS (Forces Modeling and Simulation) modules under development at Syracuse, including Parallel CMS, Object Web RTI and WebHLA based interactive training and authoring tools. Parallel CMS is our port to the Origin2000 platform of the Comprehensive Mine Simulation (CMS) System under development by the Night Vision Lab at Ft. Belvoir, VA. The system simulates a broad spectrum of minefields, their components and individual mine technologies, and it cooperates with ModSAF that is used to support terrain databases and simulation of vehicles propagating through terrain areas with minefield obstacles. At Syracuse, we are building parallel version of the CMS module to run on the Origin2000 platform and we are also developing a Windows NT based commodity visualization front-end based on Microsoft DirectX/Direct3D interactive multimedia technologies. In this metacomputing demo, we will attempt to integrate the following modules: a) an early version of our Parallel CMS running at ARL MSRC in Aberdeen, MD; b) a set of ModSAF vehicles running on a workstation cluster at Syracuse; and c) our visualization front-end running on NT laptops in Orlando. JWORB (Java Web Object Request Broker) is new middleware technology from Syracuse that enables distributed objects based Web computing by offering a uniform software bus that integrates Web HTTP and CORBA IIOP protocols. We have recently developed Object Web RTI - a full implementation of DMSO RTI 1.3 packaged as a Java/CORBA based JWORB service. We also specified our 3-tier WebHLA architecture that builds DMSO HLA on the pervasive Web base and it includes: a) Commodity Front-Ends such as DirectX Multimedia, b) Object Web RTI middleware; and c) JWORB encapsulated FMS simulation modules. We will present early WebHLA demos of OW-RTI for DMSO Jager game and of our OMDT-style FOM/SOM authoring tool OMBuilder with XML scripting support, constructed by VBA extension of the Microsoft Excel control. Metacomputing support for CMS - Comprehensive Minefield Simulation CMS is an advanced DIS system under development by the Nigh Vision Lab at Ft. Belvoir, VA. CMS simulates a broad spectrum of mines, minefields and countermines and it cooperates with ModSAF based terrain and vehicle simulators. Modern warfare requires minefields of millions and more mines and the associated simulations require High Performance Computing support. Syracuse University is building Metacomputing CMS by porting the CMS module to Origin2000 and linking it with a collection of distributed simulators handling terrain, vehicles and visualization. Current demo illustrates initial capabilities of the system and it includes: a) Parallel CMS running on Origin2000 at ARL MSRC; b) a set of ModSAF vehicles running at Syracuse workstations; and c) visualization front-ends including Mak Stealth and in-house made PC/Direct3D based CMS viewer. Work is under way to provide HLA based federation support and to include HPC resources at CEWES MSRC. Demos: 1) OMDTBuilder 2) Donuts with Automatic Interaction Generator through Web Interface To reveal the OWRTI Functionality. 3) CMS demo with Origin2000 & DirectX Output JDIS for direct performance analysis. DirectX based Visual front end has DIS PDU parse capability. 4) HeartBeat Demo from Ankur(?) To show the possible usage of RTI Middleware for Cluster Management purposes. 5) WebFlow Demos(?)
