Imagine you want to explore the atto-scale universe to determine what drives the earliest nanosecond quantum fluctuations at the birth of our Universe. To do so you'll need to build a computing system of 100,000 CPUs with access to PetaBytes of data that scale with Moore's law and Kryder's law. Network capacity will increase with Butter's law such that a Global system can be considered. You'll have to build this up within ten years and then make sure its stable and secure for thousands of users yet scales in compute power for up to twenty years. These considerations led to the adoption of the Grid for particle physics ten years ago. As the associated machine is now ready to start we highlight the challenges that have been overcome and those that lie ahead in Grid computing for the LHC.
The Large Hadron Collider (LHC) will enable us to explore the smallest distance scales and reach back to the earliest moments after the Big Bang. The complexity of the collider and detector systems is matched with a computing system that enables thousands of collaborators to share data worldwide. The Grid that has been developed is now providing compute and data resources for particle physics and a wide range of other disciplines. The talk will describe the steps taken to build the current Grid system, highlight the current issues, and explore what might be achievable using distributed computing systems of the future.
