Abstract

In this paper, we discuss the computational complexity of the problem of configuring a computing site. The theoretical considerations are based on the Quattor framework configuration model. We also present some experimental results. Quattor is a framework for managing large scale computing fabrics. It is a result of developments of the Fabric Management Work Package of the European DataGrid project. Our experience on using the Quattor framework in the DataGrid testbed and the CERN Computing Centre shows that the ability of proper configuration and management of a computing fabric is essential for having a working grid.
