Foil 46 Integration of DIS with Object Web Based Computing

From Overview of Integration of Databases and Distributed Objects with the Web Tutorial: ITEA HPCC Conference Aberdeen Md. -- July 13 98. by Geoffrey Fox, Nancy McCracken
1 DoD modeling and simulation (FMS,IMT) community is currently evolving towards the HLA(High level Architecture) framework with the RTI (Run Time Infrastructure) based communication bus.
2 The goal of HLA/RTI is to enhance interoperability across more diverse simulators than in the DIS realm, ranging from real-time to time-stepped to event-driven paradigms.
3 HLA defines a set of rules governing how simulators (federates) interact with each others. Federates describe their objects via Object Model Template (OMT) and agree on a common Federation Object Model (FOM).
4 The overall HLA/RTI model is strongly influenced by the CORBA architecture and in fact the current prototype development is indeed CORBA based.
5 Building HPCC on the Object Web implies that we can a common framework for both distributed (event driven) simulations and classic time stepped parallel computing
