When scientists at the European Organisation for Nuclear Research (CERN), Switzerland, developed a data sharing system for physicists 21 years ago, little did they know that it would blossom into the World Wide Web (www) and revolutionise communications creating an array of benefits such as the development of international collaborative research infrastructures. Collaboration has always been very much part of the success of the web according to Tim Berners-Lee, the man attributed with inventing the world-wide web. “The human nature that I came across from the early web developers was very open, very giving, people very much working together, encouraging each other, very much full of excitement, getting a kick out of making things work together. The collaborative spirit was a driver for most of the people.1” As the web has developed and global collaboration becomes a feature of everyday life, collaboration in scientific research between Europe and India has also grown. The development of Grid Computing which sees the application of computational resources from numerous computers in a single network, now allows scientists to share information and computer power. Often compared with the electrical power grid offering users access to a massive reservoir of computational power, Grid Computing can potentially transform any desktop PC into the equivalent of a ‘super’ computer. The Worldwide Large Hadron Collider (LHC) Computing Grid (WLCG) is the perfect example of collaboration between a global network of researchers. The WLCG links grid infrastructures and computer centres around the world including India, storing and analysing the immense amounts of data generated by the LHC at CERN, the most powerful physics experiment ever built.

will combine the computing resources of more than 100,000 processors from more than 170 sites in 34 countries and will be accessible to thousands of physicists globally who will have real-time access to a massive 15 petabytes of data annually, the equivalent of the storage capacity of 20 million CDs. The development of Grid Computing has gone hand-in-hand with advances in global computing connectivity and also e-Infrastructures - innovative research environments in which researchers, whether working in the context of their home institutions or in national or multinational scientific initiatives, have shared access to unique, distributed scientific facilities including data, networks, tools and computing resources. The Indian Landscape Two main grids exist in India – the Regional WCLG Grid and GARUDA, the India National Grid Initiative (http://www. garudaindia.in/). GARUDA, managed by EU-IndiaGrid2 partner the Centre for Development of Advanced Computing (CDAC), is a collaboration of scientific and technological researchers on a nationwide grid comprising computational nodes, mass storage and scientific instruments which will provide the technological advances required to enable data and compute intensive science for the 21st century. With the growth of Indian Telecom and IT skills, Indian connectivity is allowing the evolution of e-Infrastructures uniting universities and research institutes. The Indian National Knowledge Network (NKN) aims to interconnect all higher education and scientific development institutions, some 5,000, with a high-speed network in the order of 10s of gigabits per second, providing the backbone for a scientific research e-Infrastructure in India. With 14 GARUDA sites currently connected with
Alberto Masoni INFN & EU-IndiaGrid2 Project Manager the NKN, including two LHC computing sites in Mumbai and Kolkata, it is clear that work to develop collaborative research communities is advancing well. The establishment of a reliable and quick connection between India and Europe has also been improving rapidly in recent years leading to the first file transfer in 2007 between CERN and India on the WLCG. Prominent landmarks have seen the establishment of the 45 Mbps ERNET-GEANT link and routing of regional WLCG data to CERN and subsequently EU-IndiaGrid traffic to EGEE, the European Grid Infrastructure, in 2006. In 2008, the GEANT-ERNET link was upgraded to 100 Mbps and then to 175 Mbps in 2009 which included an upgrade of domestic bandwidth for regional the WLCG network. 2008 also saw a dedicated 1 Gbps TIFR-CERN link for LHC research and peering with GEANT1 in 2009. In April 2009, the first phase of the NKN was initiated while February 2010 saw a major milestone achieved with the establishment of the The Trans-Eurasia Information Network (TEIN3) (http://www.tein3.net/) 2.5 Gbps GEANT link to India.
