The computational requirements for the new Large Hadron Collider are enormous: 5-8 PetaBytes of data generated annually with analysis requiring 10 more PetaBytes of disk storage and the equivalent of 200,000 of today’s fastest PC processors. This will be a very large and complex computing system, with about two thirds of the computing capacity installed in(More)
This paper describes the quattor tool suite, a new system for the installation, configuration, and management of operating systems and application software for computing fabrics. At present Unix derivatives such as Linux and Solaris are supported. Quattor is a powerful, portable and modular open source solution that has been shown to scale to thousands of(More)
We present a framework for the co-ordinated, autonomic management of multiple clusters in a compute center and their integration into a Grid environment. Site autonomy and the automation of administrative tasks are prime aspects in this framework. The system behavior is continuously monitored in a steering cycle and appropriate actions are taken to resolve(More)
