The DoD High Level Architecture: an update
1998 Winter Simulation Conference. Proceedings (Cat. No.98CH36274), 1998Co-Authors: Judith S. Dahmann, R.m. Fujimoto, Richard M. WeatherlyAbstract:The DoD High Level Architecture (HLA) provides the specification of a common technical Architecture for use across all classes of simulations in the US Department of Defense. It provides the structural basis for simulation interoperability. The baseline definition of the HLA includes the HLA rules, the HLA interface specification (IFSpec), and the HLA object model template (OMT). The HLA rules are a set of 10 basic rules that define key principles used in the HLA as well as the responsibilities and relationships among the components of an HLA federation. The HLA IFSpec provides a specification of the functional interfaces between HLA federates and the HLA runtime infrastructure. The HLA OMT provides a common presentation format for HLA simulation and federation object models. The paper provides a description of the development of the HLA, a technical description of the key elements of the Architecture, and a discussion of HLA implementation, including HLA support processes and software.

time management in the dod high Level Architecture
Workshop on Parallel and Distributed Simulation, 1996Co-Authors: R.m. Fujimoto, Richard M. WeatherlyAbstract:Recently, a considerable amount of effort in the U.S. Department of Defense has been devoted to defining the High Level Architecture (HLA) for distributed simulations. This paper describes the time management component of the HLA that defines the means by which individual simulations (called federates) advance through time. Time management includes synchronization mechanisms to ensure event ordering when this is needed. The principal challenge of the time management structure is to support interoperability among federates using different local time management mechanisms such as that used in DIS, conservative and optimistic mechanisms developed in the parallel simulation community, and real-time hardware-in-the-loop simulations.

The Guidelines and JPEG Encoder Study Case of System Level Architecture Exploration Using the SpecC Methodology
System on Chip Design Languages, 2002Co-Authors: Lukai Cai, M. Olivarez, Daniel D. GajskiAbstract:To implement chip design on satisfactory target Architecture, more Architecture exploration should be done at higher Levels of abstraction, in the earliest design stages. Using the SpecC language, Architecture exploration can be processed easily and smoothly. A SpecC methodology of system Level Architecture exploration is introduced within this paper to illustrate this process. The design of a JPEG encoder is used as an example to illustrate the system Level Architecture exploration methodology.

ISCAS 2001. The 2001 IEEE International Symposium on Circuits and Systems (Cat. No.01CH37196), 1Co-Authors: Lukai Cai, Daniel D. Gajski, M. OlivarezAbstract:To implement chip design on satisfactory target Architectures, Architecture exploration should be done at higher Levels of abstraction, in the earliest design stages. Using the SpecC language, an executable system Level design language, system Level Architecture exploration can proceed easily and smoothly as the system specification is being created. A SpecC methodology of system Level Architecture exploration is introduced within this paper to illustrate this process. The design of a JPEG encoder is used as an example to illustrate the system Level Architecture exploration methodology.

Research on Service-Oriented High Level Architecture
Computer Simulation, 2012Co-Authors: Wu Hai-bingAbstract:To solve the deficiency of traditional High Level Architecture(HLA)in solving large scale simulation and improve the interoperability under WAN,the Service Oriented Architecture(SOA)was combined to HLA,the Run-Time Infrastructure(RTI)layered framework was designed.The solutions of Web Services Provider RTI Component and federates design were given,and the dynamic modeling and simulation methodology based on semantic web services were put forward.An instance was tested under laboratory conditions,and the results show that it can achieve the expansion of HLA to WAN and support the dynamic discovery and execution of simulation services.This research has a certain reference value for the combination of SOA and HLA.

ZERO LOOKAHEAD AND REPEATABILITY IN THE HIGH Level Architecture
1999Co-Authors: R.m. Fujimoto, GeorgiaAbstract:A distributed simulation is said to be repeatable if successive executions utilizing the same inputs produce exactly the same outputs. Repeatability is a highly desirable property, particularly for analytic simulation models. This paper discusses the question of repeatability in distributed simulations in general, and in the context of the High Level Architecture in particular. Specifically, allowing zero lookahead, a feature not supported in the baseline HLA, has important ramifications with respect to achieving repeatable executions. Extensions to the existing time management services in the HLA are proposed that allow (1) repeatable executions, (2) federate control over the ordering of simultaneous events, and (3) zero lookahead. The extensions proposed in this paper are currently under consideration by DMSO for possible future inclusion in the High Level Architecture time management services.
