Pulikal, Krishnan Rangarajan, Ankur Sood, " Using WebHLA to Integrate HPC FMS Modules with Web/Commodity based Distributed Object Technologies of CORBA, Java, COM and XML", In Proceedings of the Advanced Simulation Technologies Conference ASTC 99, San Diego, April 99. HLA standards for interoperability between various DoD Modeling and Simulation paradigms are being enforced in parallel with the rapid onset of new Object Web / Commodity standards for distributed objects and componentware, emergent at the crossroads of CORBA, COM, Java, and XML technologies. WebHLA explores synergies between and integrates both trends by offering Object Web based implementation of the HLA framework. Our goal is to deliver a uniform platform that facilitates conversion of legacy codes to and development of new codes in compliance with HLA, HPC and Object Web standards. We outline here the overall design of WebHLA, we summarize the system components prototyped so far and we illustrate our approach for one HPC FMS application - Parallel CMS (Comprehensive Mine Simulator) - in the area of large scale minefield simulation and countermine engineering. 2.

Sood, "WebHLA as Integration Platform for FMS and other Metacomputing Application Domains", In Proceedings of the DoD HPC Users Group Conference, Monterey, CA, June 8-15, 1999. High Level Architecture (HLA) standards for interoperability between various Modeling and Simulation paradigms are being enforced by the DoD in parallel with the rapid onset of new Object Web / Commodity standards for distributed objects and componentware, emergent at the crossroads of CORBA, COM, Java, and XML technologies. WebHLA explores synergies between and integrates both trends by offering Object Web based implementation of the HLA framework. Our goal is to deliver a uniform platform that facilitates conversion of legacy codes to and development of new codes in compliance with HLA, HPC and Object Web standards. In this paper: a) we outline the overall design of WebHLA; b) we summarize the system components prototyped so far; c) we illustrate our approach for one HPC FMS application - Parallel CMS (Comprehensive Mine Simulator) - in the area of large scale minefield simulation and countermine engineering; and finally d) we describe initial steps within our WebHLA based approach towards more general purpose Metacomputing, initially driven by FMS applications but applicable also for other CTAs within the HPC Modernization Program. 3. CRPC Book Chapter, Morgan-Kaufmann 2000 (in progress): WebHLA based Metacomputing Environment for Forces Modeling and Simulation We discuss here the use of HPC for the DoD Modeling and Simulation, addressed by the Forces Modeling and Simulation (FMS) Computational Technology Area (CTA) within the DoD HPC Modernization Program. Syracuse University acts as a technical lead of the academic part, PET (Programming Environments and Training) of the FMS CTA and we provide assistance for the FMS users both in the infrastructure and application development sectors. Our approach presented here explores synergies among and integrates distributed object standards emerging from industry (CORBA), Web (Java, XML) and the DoD (HLA). More specifically, we developed a 3-tier WebHLA environment that offers standards based plug-and-play support both for the back-end HPC simulation modules and for the front-end Web/Commodity interfaces. In this section, we overview DoD Modeling and Simulation domain from the perspective of HPC, we summarize the High Level Architecture (HLA) standard, we outline our WebHLA environment and we illustrate its use for building a metacomputing level battlefield simulation that involves large scale minefields (of order of million mines).
