Windows HPC hits top 10 among supercomputers

November 19, 2008 12:00 PM ET

Network World - Microsoft Corp. on Tuesday hit another high-performance computing (HPC) milestone by placing its server for the first time in the top 10 on the list of the Top 500 super computers as judged by Top500.org.

Just a year ago, the best Microsoft could do was 116th place based on rankings from Top500.org, which has been benchmarking supercomputers since 1993 with its bi-annual tests it calls "runs."

Windows HPC Server 2008, a 64-bit system that shipped Nov. 1, came in at No. 10, achieving 180.6 teraflops with 77.5% efficiency at the Shanghai Supercomputer Center and Dawning Information Industry Corp. A teraflops is a trillion floating-point operations per second.

Despite the high ranking, Microsoft's biggest high-performance computing challenge -- creating easy-to-use developer tools for writing applications for the platform -- is likely ahead of it.

The company's HPC strategy is to cut the cost and complexity of HPC, and surrounding its system with Microsoft's collection of applications, management wares, development tools and the independent software vendor community.

Microsoft currently lays claim to less than 5% of HPC server market revenue, according to market research firm IDC. Those numbers compare with 74% for Linux and just over 21% for Unix variants.

In addition, competitors such as Red Hat Inc. have been offering its Enterprise Linux for HPC Compute Nodes since last year. IBM is also in the mix, and Sun late last year re-entered the HPC fray with its Constellation System.

The next major milestone for Microsoft will come in the next year when it releases Visual Studio 2010, which was introduced last month at its Professional Developers Conference (PDC) and includes features that make it easier to design for parallel computing.

"The importance that development tools play in all of this can't be overestimated," says Charles King, an analyst at Pund-IT Inc. "The money and the effort Microsoft is putting into developing Visual Studio and other tools is really critical to making this work. Clustered systems have been around for a while, but one reason Linux has been such a popular platform is due to the complexity of writing for parallel environments. The easy customization of Linux allowed people in the know to get in there and design, build and tweak the system to maximize performance."

One of the HPC-related features coming in Visual Studio 2010 is .Net Parallel Extensions, which is designed to exempt developers from having to have specialized knowledge to write parallel code. Also included for transitioning to parallel code are Task Parallel Library, Parallel LINQ and Coordination Data Structures for managed code.

Microsoft also released a preview last month of its F# language, which is a specialty language that will help developers to easily write parallel code.
