Description
The lecture introduces the topic of Grid Computing on the example of
high energy physics. Through presentations and hands on trainings the
participants will gain knowledge about the LCG-2 middleware, the common
grid environment of all four experiments of the upcoming Large Hadron
Collider. Although developed in the HEP-environment, LCG-2 is also of
more general use. For example, Biomedical applications are pilot users
of the LCG-2 middleware. The project also provides essential contributions
to the European Union grid project EGEE (\"Enabling Grid for
ESciencE\"). The perspectives of this project and the technical
background of the corresponding middleware gLite will be discussed.
Topics covered by the lecture include:
Introduction and motivation for Grid Computing
Historical development of Grid Computing
Standards in Grid Computing
Grid and Web Services and the Global Grid Forum
Various grid projects: The European Data Grid (EDG), LCG, AliEn, gLite and EGEE
Detailed introduction to the components of the LCG-2 middleware and their
functionality
Hands-on training in LCG-2 (basic principles of job description, job submission and data management)
An example application (high-energy physics data analysis) using LCG-2
and the ROOT toolkit
Grid Applications
Introduction to the next-generation EGEE gLite
middleware (based on LCG-2), its components and functionality
