Windows Server HPC Pack
A variable unknown edition of Windows Server is the HPC edition. Since all computers and servers today have multiple cores (2,4,6,8-cores), there is an opportunity to use the processing power of those cores when not in use. Enter HPC. HPC or "High Performance Computing" is a new service that allows hardware to be grouped together and jobs assigned to run against those cores during off hours. Try it and see it in action at Microsoft Labs.
