A Computational Grid is a collection of heterogeneous computers and resources spread across multiple administrative domains with the intent of providing users easy access to these resources. There are many ways to access the resources of a Computational Grid, each with unique security requirements and implications for both the resource user and the resource provider. A comprehensive set of Grid usage scenarios is presented and analyzed with regard to security requirements such as authentication, authorization, integrity, and confidentiality. Th ....etc

Amazon.com's Best of 2001
Five years ago, Jim Collins asked the question, Can a good company become a great company and if so, how? In Good to Great Collins, the author of Built to Last, concludes that it is possible, but finds there are no silver bullets. Collins and his team of researchers began their quest by sorting through a list of 1,435 companies, looking for those that made substantial improvements in their performance over time. They finally settle ....etc

1. Introduction
The last decade has seen a substantial increase in commodity computing and network performance, mainly as a result of faster hardware and more sophisticated software. These commodity technologies have been used to develop low-cost high-performance computing systems, popularly called clusters, to solve resource-intensive problems in a number of application domains. Particularly, in the scientific arena, the availability of powerful computing resources has allowed scientists to broaden their simulations and e ....etc
