The Windows HPC Server 2008 Beta has now begun!
Windows HPC Server 2008 enables cluster based supercomputing based on x64 versions of Windows Server 2008 (32-bit and ia64 hardware is not supported). Windows HPC Server can be used for massively parallel programs (computational fluid dynamics, reservoir simulation) as well as embarrassingly parallel programs (BLAST, Monte Carlo simulations).
The Windows HPC Server is a cluster of servers that includes a single head node, and one or more compute nodes. The head node controls and mediates all access to the cluster resources and is the single point of management, deployment and job scheduling for the compute cluster. It utilizes the existing corporate Active Directory infrastructure for security and account management.
