Client/server systems have been touted as the next step in the advance of the computer into modern, computer-aided drafting (CAD), computer-aided engineering (CAE), geographical information systems (GIS), engineering information (EI) technology, and information technology (IT) society, but they...

This paper is an overview of part of the beam optics code development effort in the Accelerator Technology Division at Los Alamos National Laboratory. The aim of this effort is to improve our capability to design advanced beam optics systems. The work reported is being carried out by a...

The Information Management Technology Architecture (TA) is being driven by the business objectives of reducing costs and improving effectiveness. The strategy is to reduce the cost of computing through standardization. The Lockheed Martin Idaho Technologies Company (LMITCO) TA is a set of...

Good decision-making in materials accounting requires a valid calculation of control limits and detection sensitivity for facilities handling special nuclear materials (SNM). A difficult aspect of this calculation is determining the appropriate variance and covariance values for the terms in the...

To help integrate activities in the environmental restoration and waste management mission of the Hanford Site, the Hanford Integrated Planning Project (HIPP) was established and funded by the US Department of Energy. The project is divided into three key program elements, the first focusing on...

A computing architecture is a framework for making decisions about the implementation of computer technology and the supporting infrastructure. Because of the size, diversity, and amount of resources dedicated to computing at the Savannah River Site (SRS), there must be an overall strategic plan...

Multiple copper-based commodity Gigabit Ethernet (GigE) interconnects (adapters) on a single host can lead to Linux clusters with mesh/torus connections without using expensive switches and high speed network interconnects (NICs). However traditional message passing systems based on TCP for GigE...

Structural system identification methods are analytical techniques for reconciling test data with analytical models. The response data frequently used to compare a finite element model and test data are the eigenvalues of the system. However, eigenvalues alone cannot assure an adequate model....

As enterprises become increasingly information based, making improvements in their information activities is a top priority to assure their continuing competitiveness. A key to achieving these improvements is developing an Enterprise Information Architecture (EIA). An EIA can be viewed as a...

With the ratification of the Threshold Test Ban Treaty (TTBT), there has been increased interest in lowering the nuclear test ban threshold from its present level of 150 kilotons and much debate about what this lower threshold should be. The uncertainties associated with verifying the TTBT,...

This report presents a discussion of directory-enabled policy-based networking with an emphasis on its role as the foundation for securely scalable enterprise networks. A directory service provides the object-oriented logical environment for interactive cyber-policy implementation. Cyber-policy...

Stanford Linear Accelerator Center (SLAC) was faced with the need to secure its PeopleSoft-Oracle business system in an academic environment that has no firewall. To provide protected access to the database servers for NT-based users all over the site while not hindering the lab's open...

We seek to understand which supercomputer architecture will be best for supercomputers at the Petaflops scale and beyond. The process we use is to predict the cost and performance of several leading architectures at various years in the future. The basis for predicting the future is an expanded...

In July of 1988, Argonne National Laboratory management approved the restructuring of Computing Services into the Computing and Telecommunications Division, part of the Physical Research area of the Laboratory. One major area of the Computing and Telecommunications Division is Management...

Speculation plays an ever-increasing role in optimizing the execution of programs in computer architecture. Speculative decision-makers are typically required to have high speed and small size, thus limiting their complexity and capability. Because of these restrictions, predictors often...

Arithmetically each level of human generation contributes to 6.72 generations of Computer upgrading. But, this effect could pay back to the human society only by tuning the corporate infrastructure to utilise these computer innovations optimally. The future computer electronics works towards...
