Message Passing for Linux Clusters with Gigabit Ethernet Mesh Connections

Jie Chen; Chip Watson; Robert Edwards; Weizhen Mao - 2008

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...

Modeling attacker-defender interactions in information networks.

Collins, Michael Joseph - 2011

The simplest conceptual model of cybersecurity implicitly views attackers and defenders as acting in isolation from one another: an attacker seeks to penetrate or disrupt a system that has been protected to a given level, while a defender attempts to thwart particular attacks. Such a model also...

Managing Errors to Reduce Accidents in High Consequence Networked Information Systems

Ganter, J.H. - 2008

Computers have always helped to amplify and propagate errors made by people. The emergence of Networked Information Systems (NISs), which allow people and systems to quickly interact worldwide, has made understanding and minimizing human error more critical. This paper applies concepts from...

Positioning the electric utility to build information infrastructure

2008

In two particular respects (briefly investigated in this study from a lawyer`s perspective), electric utilities appear uniquely well-positioned to contribute to the National Information Infrastructure (NII). First of all, utilities have legal powers derived from their charters and operating...
