On July 7th, 2011, Microsoft published a free document entitled "Introducing Windows HPC Server 2008 R2 SP2" available through the Microsoft Download Center.
The free whitepaper is sponsored by the software giant and authored by David Chappell, Principal of DavidChappell & Associates, and is designed to provide insight into Windows HPC Server for those customers running parallel applications on clusters.
"To support Windows-based clusters, Microsoft provides Windows HPC Server 2008 R2. This technology offers a way to create and manage clusters built using Windows servers, Windows desktop workstations, and Windows Azure instances in the public cloud," Chappell explains.
"The goal is to support high-performance computing (HPC), a category that includes a range of applications that can benefit from being distributed across a cluster. To allow this, Windows HPC Server 2008 R2 Service Pack (SP) 2 supports four major types of parallel applications.
This paper provides an introduction to Windows HPC Server 2008 R2 SP2, including a look at the services it provides for creating and using clusters and an overview of how it supports each of the four application types."
