Epidemiological modeling for infectious disease is important for disease management and its routine implementation needs to be facilitated through better description of models in an operational context. A standardized model characterization process that allows selection or making manual comparisons of available models and their results is currently...

Multithreading can significantly increase the performance of large agent-based simulations on multicore systems, but agent-based software packages do not commonly offer adequate support for multithreading. This report describes alterations and additions made to the MASON agent-based simulation package that allow the application programmer to make u...

The goal of the Collaboratory for the Multi-scale Chemical Sciences (CMCS) [1] is to develop an informatics-based approach to synthesizing multi-scale chemistry information to create knowledge in the chemical sciences. CMCS is using a portal and metadata-aware content store as a base for building a system to support inter-domain knowledge exchange...

This paper describes the details of a hardware realization of a framework to support parallel discrete event simulation [Reyn92]. We first motivate the need for hardware to compute and disseminate critical synchronization information in all parallel simulations. We establish correctness criteria and functional requirements of the framework hardware...

Collaboration tools and problem solving environments (PSEs) have historically evolved independently, despite the fact that most of their developers would agree that transitions between team and individual work are facile and frequent in the real world. The explanation of this paradox has roots in both technology limitations and our lack of understa...

The development of agent systems based on layered agent templates has expanded the development and deployment of agent applications. We are developing an agent template to support the integration of a wide range of enterprise applications.

The Diesel Combustion Collaboratory (DCC) is a pilot project to develop and deploy collaborative technologies to combustion researchers distributed throughout the DOE national laboratories, academia, and industry. The result is a problem-solving environment for combustion research. Researchers collaborate over the Internet using DCC tools, which in...

The global marketplace and the Internet have served as catalysts for enterprise integration (EI), both within a company and between a company and its suppliers and partners. EI software architectures, or frameworks, are often built on top of standard middleware and typically lack the ability to function in dynamic environments where flexibility, ad...

The authors are developing and deploying software agents in an enterprise information architecture such that the agents manage enterprise resources and facilitate user interaction with these resources. The enterprise agents are built on top of a robust software architecture for data exchange and tool integration across heterogeneous hardware and so...

Distributed object and software agent technologies are two integration methods for connecting enterprises. The two technologies have overlapping goals--interoperability and architectural support for integrating software components--though to date little or no integration of the two technologies has been made at the enterprise level. The primary dif...

A CORBA based distributed object software system was developed for Sandia's Agile Manufacturing Testbed (SAMT). This information architecture supports the goals of agile manufacturing: rapid response to changing requirements; reduction in both time and cost of the product realization process; and integration within a heterogeneous, wide area networ...

It is critical in today's enterprises that manufacturing facilities are not isolated from design, planning, and other business activities and that information flows easily and bidirectionally between these activities. It is also important and cost-effective that COTS (commercial-off-the-shelf) software, databases, and corporate legacy codes are wel...

In recent years, manufacturers of high precision mechanical parts have been required to produce increasingly complex designs, in smaller lot sizes, with improved quality. These requirements demand lower process costs, shorter development cycles and more accurate manufacturing technologies. To meet these demands, manufacturers are attempting to both...

Building on Reynolds's hardware/software framework for parallel discrete event simulation (PDES), we establish a number of novel and best known results based on the use of reduction-based computing to support PDES. We demonstrate the utility of reduction-based computing to a spectrum of wellknown PDES synchronization protocols, such as conservative...

It has been established elsewhere (Reynolds, Int. J. Comput. Simulation, to appear) that hardware to support parallel discrete event simulations (PDES) is desirable. We describe the steps leading to the implementation of a hardware-based framework to support PDES. We begin with an exploration of the criteria that must be met to make such a framewor...

A hardware-based framework which supports a wide range of parallel discrete event synchronization protocols has been proposed in [Reyn92].
