Sixteenth Systems Administration Conference,
USENIX Association, 2002).
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 ``regional computing centres'' across Europe,
America, and Asia.
Implemented as a global computational grid, the goal of
integrating the large geographically distributed computing fabrics
presents challenges in many areas, including: distributed scientific
applications; computational grid middleware, automated computer system
management; high performance networking; object database management;
security; global grid operations.
This paper describes our approach to one of these challenges: the
configuration management of a large number of machines, be they nodes
in large clusters or desktops in large organizations.
