I remember back in 2005, when Microsoft, an HPC outsider, created buzz in the supercomputing and grid computing spaces by tapping Tony Hey of the UK’s seminal e-Science Programme to serve as VP of Technical Computing. Later that year, Bill Gates keynoted the annual Supercomputing conference, and shortly thereafter Windows Compute Cluster Server came to fruition. In 2007, Microsoft added Dan Reed to its mix. Now, Redmond is an epicenter of webscale and high-end data center research, as evidenced by its new eXtreme Computing Group. What a difference a few years makes.
