Performance modeling in the design process
Alexander, W.; Brice, R. - 2009
Here, in capsule form, are some lessons learned trying to integrate performance modeling into the design process. Performance modeling should play a central role in system design; ignore it at your peril. The role of performance modeling is not the same in all design projects. Clearly specify...

1991 Annual report on scientific programs: A broad research program on the sciences of complexity
2008
1991 was continued rapid growth for the Santa Fe Institute (SFI) as it broadened its interdisciplinary research into the organization, evolution and operation of complex systems and sought deeply the principles underlying their dynamic behavior. Research on complex systems--the focus of work at...

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...

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...

Managing Complex IT Security Processes with Value Based Measures
Abercrombie, Robert K; Sheldon, Frederick T; Mili, Ali - 2010
Current trends indicate that IT security measures will need to greatly expand to counter the ever increasingly sophisticated, well-funded and/or economically motivated threat space. Traditional risk management approaches provide an effective method for guiding courses of action for assessment,...

Critical infrastructure systems of systems assessment methodology.
Sholander, Peter E.; Darby, John L.; Phelan, James M.; … - 2008
Assessing the risk of malevolent attacks against large-scale critical infrastructures requires modifications to existing methodologies that separately consider physical security and cyber security. This research has developed a risk assessment methodology that explicitly accounts for both...
