Windows HPC Server 2008

Windows HPC Server 2008, released in September 2008, is the successor product to Windows Compute Cluster Server 2003. Like WCCS, Windows HPC Server 2008 is designed for high-end applications that require high performance computing clusters. This version of the server efficiently scales to thousands of cores and includes features unique to HPC workloads: a new high-speed NetworkDirect RDMA, highly efficient and scalable cluster management tools, a service-oriented architecture (SOA) job scheduler, and cluster interoperability through standards such as the High Performance Computing Basic Profile (HPCBP) specification produced by the Open Grid Forum (OGF).

In June 2008, a system built collaboratively with the National Center for Supercomputing Applications (NCSA) and Microsoft ranked #23 on the Top500 list, a ranking of the world’s fastest supercomputers, with a LINPACK score of 68.5 teraflops.

In the November 2008 rankings published by, a Windows HPC system built by the Shanghai Supercomputer Center achieved 180.6 teraflops, a peak performance that placed the so-called Dawning 500A system at #10 on the list of the world’s fastest supercomputers.
