High Performance Computing has been around for a long time but is starting to make headway into more and more areas. It is no longer just used in research, scientific and academic areas. A while ago I showed wrote how some research being done with HPC affects our daily lives (http://blogs.technet.com/canitpro/archive/2008/02/13/hpc-in-the-real-world.aspx)
That is cool and I continue to see how HPC is making its mark in everyday life. Like Xbox games for example. Seven Group in Vancouver BC is doing some cool things with their Windows HPC based render farms that are allowing xBox games to look better than ever!
