In India, Mumbai's Tata Institute of Fundamental Research and the Variable Energy Cyclotron Centre, Kolkata, have tier 2 systems. The Baba Atomic Research Centre (BARC), too, has contributed to the software used in the grid technology. BARC's contribution has been towards making software tools, problem-solving tools, and monitoring tools. The main aim is to see that smooth operations go on, since it is a wide network of countries from over the world.
