LHC-era computing

This course aims to show why computing for the LHC era will be difficult, and also why it will be interesting! An LHC experiment will be faced by some billion events per second. Even after the most rigorous selection, an experiment may record 1 Terabyte per day. How will this be organized, how shall we find the computing power? How shall we make the data easily accessible for analysis by thousands of physicists all over the world? And how shall we develop the sofware we need to do the job? We give an outline of these problems and the new approaches and technologies that will help us to solve them
