World's Largest Computing Grid Surpasses 100 Sites

Geneva, 15 March 2005 – Today, the Large Hadron Collider Computing Grid (LCG) project announced that the computing Grid it is operating now includes more than 100 sites in 31 countries. This makes it the world's largest international scientific Grid. This Grid is being established in order to deal with the anticipated huge computing needs of the Large Hadron Collider (LHC), currently being built at CERN1 near Geneva, Switzerland. The sites participating in the LCG project2 are primarily universities and research laboratories. They contribute more than 10,000 central processor units (CPUs) and a total of nearly 10 million Gigabytes of storage capacity on disk and tape. This Grid receives substantial support from the EU-funded project Enabling Grids for E-sciencE (EGEE), which is a major contributor to the operations of the LCG project.

The LHC is a particle accelerator used to study the fundamental properties of sub-atomic particles. It is due to start operating in 2007. The LCG project was launched in 2003 and is growing rapidly. The Grid operated by the LCG project is already being tested by the four major experiments that will use the LHC, namely ALICE, ATLAS, CMS and LHCb, to simulate the computing conditions expected once the LHC is fully operational. As a result, the LCG partners are achieving record-breaking results for high-speed data transfer, distributed processing and storage. Already, other scientific applications from disciplines such as biomedicine and geophysics are being tested on this unique computing infrastructure, with the support of the EGEE project3.

 

Grid computing is a term used for many varieties of distributed computing. For the LCG project, the objective is to unite the computing capacity that exists in scientific organizations around the globe. This requires special middleware – the software that allows seamless operations across multiple institutional domains – so that users of the Grid perceive it as a single resource. Underlying the middleware is the basic infrastructure of this Grid, which consists of extremely high speed networks, clusters of hundreds of computers at the participating sites, as well as banks of disk servers and tape silos for the data storage, also distributed around the globe.

The LCG Project Leader Les Robertson, based at CERN's IT Department, said: "We are well ahead of our original schedule for reaching 100 sites, and thanks is due to the many partner sites around the world for their contribution to this success - making a Grid like this is a truly collaborative effort."

The Global Grid Forum, which is a community-initiated forum of thousands of individuals from industry and research leading the global standardization effort for Grid computing, is meeting in Seoul this week. The Chair of the GGF, Mark Linesch, described LCG's 100-site milestone as "great news for Grids, and great news for science. Without doubt the LCG project is pushing the envelope for what an international science Grid can do."

Despite the record-breaking scale of the LCG project today, Robertson notes that the current processing capacity of this Grid is estimated to be just 5% of the long-term needs of the LHC. Therefore, the LCG will continue to grow rapidly over the coming two years, both by adding sites and increasing resources available at existing sites. In addition, the exponential increase in processor speed and disk storage capacity inherent to the IT industry will help to achieve the LHC's ambitious computing goals.

2 The mission of the LHC Computing Grid (LCG) project is to build and maintain a data storage and analysis infrastructure for the entire high energy physics community that will use the LHC. Discovering new fundamental particles and analysing their properties with the LHC accelerator is possible only through statistical analysis of the massive amounts of data gathered by the LHC detectors ATLAS, CMS, ALICE and LHCb, and detailed comparison with compute-intensive theoretical simulations. The goals of the LCG project include: developing different software components to support the physics application software in a Grid environment; developing and deploying computing services based on a distributed Grid model; managing users and their rights in an international, heterogeneous and non-centralized Grid environment; managing acquisition, installation, and capacity planning for the large number of commodity hardware components that form the physical platform for the LCG project.

The LCG project relies on advanced networking infrastructures such as the GEANT network, a multi-gigabit pan-European data communications network supported by 26 National Research and Education Networks. For more information see the LCG website.

3 The Enabling Grids for E-sciencE (EGEE) project is funded by the European Commission and aims to build on recent advances in grid technology and develop a service grid infrastructure which is available to scientists 24 hours-a-day. The project aims to provide researchers in both academia and industry with access to major computing resources, independent of their geographic location. The EGEE project identifies a wide-range of scientific disciplines and their applications and supports a number of them for deployment. To date there are five different scientific applications running on the EGEE Grid infrastructure. For more information see the EGEE website.
