ngkabra writes "In November 2007, a previously unheard of supercomputer called EKA, built by CRL, India came out of nowhere to become the 4th fastest supercomputer in the world. It is also the only supercomputer in the top 10 that hasn't taken any government funding — which means it has no strings attached against commercial exploitation. That is one of the reasons why Yahoo! chose EKA for the cloud computing research that they announced at the Hadoop Summit earlier this week. Yesterday, I attended a presentation by the team that built EKA, and they touched upon a lot of the technical details of EKA, and the challenges faced in designing and building it, which makes for interesting reading."
