India unleashes 4th fastest super computer

India has now official broke into top ten super computers in the world.

For the first time ever, India placed a system in the Top 10. The Computational Research Laboratories, a wholly owned subsidiary of Tata Sons Ltd. in Pune, India, installed a Hewlett-Packard Cluster Platform 3000 BL460c system. They integrated this system with their own innovative routing technology and achieved 117.9 TFlop/s performance.
