SUPERIOR PERFORMANCE FOR LOW-LATENCY, HIGH-THROUGHPUT CLUSTERS RUNNING WINDOWS ® HPC SERVER 2008 Windows HPC Server 2008 and Mellanox InfiniBand interconnect adapters deliver maximum performance and scalability for HPC networks. OVERVIEW WINDOWS HPC High-performance computing (HPC) SERVER 2008 has become a fundamental resource for Windows HPC Server 2008 is built on innovative researchers, scientists, analysts proven Windows Server® 2008 x64- and engineers in industries spanning bit technology, and can efficiently manufacturing, computational science, scale to thousands of processing cores. life sciences, financial services, aerospace, Windows HPC Server 2008 is simple to oil and gas, and more. These experts deploy, manage, and use with existing require dedicated HPC capacity to run infrastructure, and enables a solution that PARTNER HPC performance-sensitive applications delivers high-performance and stability.

HPC applications achieve maximum performance over InfiniBand networks because CPU cycles are available Gilad Shainer, Mellanox to focus on critical application processing instead of networking functions. Node-to- node latency of less than 2µs and almost 3GByte/sec uni-directional bandwidth has been BENEFITS demonstrated on Mellanox InfiniBand clusters using the Microsoft MS-MPI protocol. The combination of Windows With InfiniBand’s proven scalability and efficiency, small and large clusters easily scale up HPC Server 2008 and Mellanox to tens-of-thousands of nodes. InfiniBand drivers for Windows HPC Server 2008 are based InfiniBand adapters increases: on the OpenFabrics Alliance Windows driver set (WinOF), ensuring that certified, high- performance networking drivers like InfiniBand, are available to both end users and to • Performance major original equipment manufacturers (OEMs) creating HPC offerings.
