Harness the Power with Windows HPC Server 2008.

Windows HPC Server 2008
Overview: Windows HPC Server 2008, combining the power of Windows Server platform with rich, out-of-the-box functionality to help improve the productivity and reduce the complexity of your supercomputing HPC environment. Microsoft is providing Windows HPC Server for 180 days on trial basis. It can efficiently scale to thosands of processing cores and provides a comprehensive set of deployment, administration, and monitoring tools that are easy to deploy, manage, and integrate with your existing infrastructure.
Introduction: Microsoft® Windows® HPC Server 2008 (HPCS), the next generation of high performance computing (HPC), provides enterprise-class tools, performance, and scalability for a highly productive HPC environment. HPCS provides a complete and integrated cluster environment including the operating system, a Job Scheduler, Message Passing Interface v2 (MPI2) support, and cluster management and monitoring components. Built on Windows Server® 2008 64-bit technology, HPCS can efficiently scale to thousands of processing cores and includes a management console that helps proactively monitor and maintain system health and stability. Job scheduling interoperability and flexibility enables integration between Windows and Linux-based HPC platforms, and supports batch and service-oriented architecture (SOA) workloads. Enhanced productivity, scalable performance, and ease of use are some of the features that make Windows HPC Server 2008 best-of-breed for Windows environments.
Windows HPC Server 2008 is a two-DVD package comprised of Windows Server 2008 HPC Edition and the Microsoft HPC Pack 2008.
Windows Server 2008 HPC EditionThe first DVD contains the setup for a 64-bit version of Windows Server 2008 that is restricted to an HPC workload
Microsoft HPC Pack 2008
The second DVD contains Microsoft HPC Pack 2008, which provides the additional interfaces, tools, and management infrastructure described below:

Networking and MPI

System Requirements
Supported Operating Systems: Windows Server 2008
CPU: x64 architecture computer with Intel Pentium or Xeon family processors with Intel Extended Memory 64 Technology (EM64T) processor architecture; AMD Opteron family processors; AMD Phenom family processors; AMD Athlon 64 family processors; compatible processor(s)
RAM: 512 MB
Multiprocessor support: Windows Server 2008 HPC Edition and Windows Server 2008 Standard Edition support up to four processors per server. Windows Server 2008 Enterprise Edition supports up to eight processors per server.
Minimum disk space for setup: 50 GB
Disk volumes: A single system volume is required for the head and compute nodes.Redundant array of independent disks (RAID) is supported but not required.The system volume must be Master Boot Record (MBR). Additional volumes can be MBR or GUID Partition Table (GPT).
Network interface card: At least one network interface card (NIC) is required. If a private network is used, the head node requires at least two NICs, and compute nodes at least one. Each node may also require a high-speed NIC for an application network.
