Microsoft creating Windows for supercomputers

Microsoft has launched an effort to produce a version of Windows for high-performance computing, a move seen as a direct attack on a Linux stronghold.

What's new:
Microsoft has launched an effort to produce a version of Windows for high-performance computing, a move seen as a direct attack on a Linux stronghold.

Bottom line:
For now, Linux has the upper hand, owing to its affinity with Unix--the OS environment the high-performance crowd is most comfortable with--and the open-source model, which lets users turn directly to source code for answers to problems. But a Microsoft product would theoretically integrate better with Windows desktop machines, and if the company can serve up an impressive offering, Linux could be in for a tussle.

High-performance computing once required massive, expensive, exotic machines from companies such as Cray, but the field is being remade by the arrival of clusters of low-end machines. While the trend could be considered an opportunity for Microsoft, which has long been the leading operating-system company, Linux has actually become the favored software used on these clusters.

Now Microsoft has begun its response, forming its High Performance Computing team and planning a new OS version called Windows Server HPC Edition. Kyril Faenov is director of the effort, and Microsoft is hiring new managers, programmers, testers and others.

The Redmond, Wash.-based software colossus has its work cut out in the market--and knows it.

"Winning in this important space against entrenched Linux/open-source software competition requires creativity, innovation, speed of execution, and deep engagements with hardware, software and academic partners," reads a job posting for a program manager responsible for setting up the team's academic partnerships.

In a recent interview, Bob Muglia, a Microsoft senior vice president who leads the development of Windows Server, said the company is interested in two particular areas: building high-performance computing clusters and harvesting the unused processing power of PCs.

Although Microsoft is a comparative newcomer to the market, the company could bring several advantages:

• Machines running Windows HPC Edition could seamlessly connect to desktop computers, providing instant power for someone such as a financial analyst performing calculations on an Excel spreadsheet, said David Lifka, chief technology officer for the Cornell Theory Center, Microsoft's premier high-performance computing partner.

• Microsoft could create a specialized version of its widely praised programming tools, said Phil Papadopoulos, director of the grids and clusters program at the San Diego Supercomputing Center. "Windows could make that much easier with their integrated development environment. They have the manpower to do that piece of the puzzle."

• Microsoft could also adapt its popular SQL Server database software to run on high-performance systems. The company has already said the next major version of SQL Server, code-named Yukon and due next year, will include better support for very large databases and for running on clustered systems.

• And Microsoft could build software into its desktop version of Windows to harness the power of PCs, letting companies get more value from their computers. It's a technology that's applicable to tasks such as drug discovery and microchip design.

The business imperative
The high-performance effort doesn't mark the first time Microsoft has tried to head off Linux's progress. With Windows Server 2003, Microsoft released a lower-priced Web server edition, as Linux was growing popular for use on the machines that host Web sites.

"The Windows Server group is really focused on countering Linux," said Rob Helm, an analyst with Directions on Microsoft. "They've identified specific areas where Linux has the most traction."

The HPC Edition is also an example of a Microsoft strategy to increase revenue by creating versions of Windows tailored for specific market segments--for example, Windows for tablet PCs, digital TV recorders and storage servers.

"Another way for them to keep Windows sales moving is to roll out more of these editions," Helm said. "When you've got a product that you need to keep moving, one way to do it is to segment it. You introduce Tarter Control Windows Server and Sensitive Teeth Windows Server."

High-performance computing is a lucrative market, with sales that increased 14 percent to $5.3 billion in 2003, according to IDC. And "bright clusters," Linux servers that manufacturers know will be used in a cluster, had sales of $384 million in the fourth quarter.

Beating the incumbent
But for once, Microsoft is the newcomer, and Linux is the incumbent. Linux got its first foothold in academia and research labs, which already had expertise and software for the functionally similar Unix operating system.

"The majority of people doing high-performance computing are a lot more comfortable and efficient inside a Unix environment," a category that includes Linux, the SDSC's Papadopoulos said. To convince people to invest the time and money to switch, Microsoft will have to offer something much better, he said.

Linux, boosted by low-cost servers using processors from Intel and Advanced Micro Devices, now is used on prestigious machines. Thunder, a machine at the Lawrence Livermore National Laboratory with 512 Linux servers running Red Hat Enterprise Linux, can perform more than 19 trillion calculations per second, second only to Japan's Earth Simulator.

Dozens of machines in a list of the 500 fastest supercomputers run Linux, including five of the top 10. Only two on the list are identified as Windows machines.

One reason Windows has been slow to catch on is that Unix and Linux were bred to be administered remotely, a necessary feature for managing a cluster with dozens or hundreds of computers.

In Windows, "the notion of remote computing is significantly more difficult than in Unix," Papadopoulos said. "Because Windows was born out of the desktop, (it is) deeply ingrained in the Microsoft culture that you have somebody sitting in front of the machine to do work."

Management is on Microsoft's agenda, though. The company is hiring one programmer to work on a "graphical and script-based user interface for efficient job and resource management across large clusters" and another to create "automated infrastructure to uncover performance and reliability problems with high performance, large-scale server applications."

Linux adds another advantage: It's open-source software, meaning that anybody may see and modify its underlying source code. Most business customers aren't interested, but high-performance technical computing users need to extract every bit of performance and track down difficult bugs.

"The nice thing is that because everything is open, if you have a problem, you can get at the root of the problem in terms of the software. That moves things along quite a bit faster," Papadopoulos said.

That openness also makes it easier to accommodate the multitude of different technologies used in the high-performance market but not necessarily in the mainstream computing market, said Brian Stevens, vice president of operating system development for Linux seller Red Hat.

Releasing a product
Microsoft declined to share schedule information about the HPC Edition, but work is already under way.

For example, a software developer kit for HPC Edition will include support for the Message Passing Interface, or MPI, widely used software to let computers in a cluster communicate with one another.

The Cornell Theory Center's Lifka believes that an early software development kit for the HPC Edition could arrive as soon as this fall. The center is helping Microsoft develop and test the new software.

Microsoft has several upcoming server releases, to which an HPC version of Windows could be added. Service Pack 1 of Windows Server 2003 is due later this year, followed by a more substantive upgrade, code-named R2, slated for 2005. The next major update to Windows, code-named Longhorn, is scheduled to arrive in server form in 2007.

According to job postings, Microsoft is adapting MPI to Microsoft's .Net infrastructure. A key foundation of .Net is the C# programming language and the Common Language Runtime, or CLR, which lets C# programs run on a multitude of different systems.

Lifka said the first phase will use a version of MPI written for a specific operating system and hardware type. The next foundation will be a version of MPI for the CLR that will let administrators run the same programs on a wide variety of different Windows machines--for example, those using Xeon, Opteron or Itanium processors.

So far, programs written for the CLR and .Net aren't as fast as those written for a specific machine, "but we see constant improvement in that," Lifka added. Another area that needs work is security and easy patch installation, he said.

Overall, Lifka is a fan of Windows for high-performance computing. The biggest reason for his enthusiasm is that it can dovetail easily with other versions of Windows in a company.

And companies are more familiar with Windows than Linux, he added. "Moving to Windows has allowed us to have a greater number and quality of corporate relationships," Lifka said.

Microsoft takes a long-term view of the challenge.

Muglia often discusses technology moving from possible to practical to seamless, as it matures. High-performance computing on Windows today is in the possible stage, he said, but the goal is to make it practical.

"That is something that will happen in the next few years," Muglia said. "There is an opportunity to make this better."

Oh Boy!
The rush to acquire this will probably be as great as it is for Windows on mainframes.

Hardware Vendor for Windows HPC
Gee, I wonder who the hardware vendor of choice will be for this venture? Why not draw the obvious conclusion - Sun Microsystems will be on the HCL for Windows HPC before you know it. It certainly won't be Linux favorites, HPQ or IBM.

Why not just SAY it? What's holding you back? Granted, Sun must be swallowing hard to make this one work, but it makes sense in light of the recent truce called for by Gates and McNealy.

Give me a break!
As someone with years of research experience in high performance, parallel and supercomputing I can't see how Windows could meet a couple of major requirements for efficient supercomputing applications, such as: providing lightweight(!) and optimized(!) execution environment for number crunching purposes with all other services (IO, user interface, compilation, editing, data storage...) moved to front-end computers and/or processors. Now the real question is: What Microsoft assumes to be a supercomputer? Just a bit faster than usual Pentium 4 box maybe? Or they think superservers or server clusters are the same thing as supercomputers?

I believe MS is attempting to once again exploit relative computer illiteracy of an average customer/user by using bold terms for purely marketing purposes further blurring terminology up to the point when they can claim everything imaginable is invented by MS or supported by Windows. What could be the next step? Maybe providing a couple of desktop themes featuring DNA molecules and claiming that Windows is "genetic computing compliant" platform? I would not be surprised at all.

Here we go again....
Once more, some one has slapped Bill Gates across the face with
a dead carp to get his focus on one more idea that he had totally
overlooked. And once more, Bill turns to the MS cookie jar and
begins to throw money against the wall hoping to find either an
answer he can buy or an answer he can steal.

Does anyone ever wonder why DOS looks so very much like
CPM?

Leading OS Company?? I don't think so!!
I just had to send this "ZDNe Talk Back" to you since it you need to get after your writers. It has to do with the article "Microsoft creating Windows for supercomputers" by Stephen Shankland and Ina Fried. I hope you will read this and possibly try to take corrective actions and have your writers check their facts.

ZDNet - TalkBack -

I take real offense at the lie that was written in this article "Long been the leading operating-system company". Both Stephen Shankland and Ina Fried should go back to school and get their Comp Sci degrees. Maybe then they will learn who has been writing operating systems longer, IBM. I do not work for IBM nor never have. But I have been working with computers since 1980 and I know that before this, IBM was one of a few that were writing operating systems for few machines that existed at that time. As for the operating system that is the leading OS in computer technology, no operating system as yet holds a candle to the MVS operating system that run the largest data centers in the world. It also has one of the fewest hacker incident reports of all the operating systems. So please get your stories straight before you give credit to such a kid company as MicroSoft, they haven't as yet taken off their training pants.

PS: The day that MS creates a supercomputer OS is the day I'll probably retire. But I think at the rate that MS is going, I've got a number of years to go.

Interesting but incomplete
Great story. This will set the HPC initiative 20 years back!
Which operating system was used by Virginia Tech to build the
third largest supercomputer as a 2000+ cluster in record time
and little money? MAC OS X!
Which is the company that has had a HPC initiative and group for
several years and has made inroads in Biotech and other high
tech areas? Apple Computers
Where are these facts mentioned in your article? Nowhere!

Face the Facts
MS might not have been the Co, that wrote the OS and a lot of poeple know the story.... now a lot of you can keep wining about who did and who did not, whown invented and who did not .... and i can mention quiet a few of those starting from the heads of Sun, Oracle, Apple .... all the way down to you guys... i think you should retire now and save yourself the hassle of watching the HPC come through.

MS knew how to build products that suited several needs and has long been VERY successful in doint it. Now it bothers you and poeple like you that they are looking at the supercomputer arena ???? WATCH THEM DO IT ...
I don't think your position is much better then the longtime inventor of supercomputers (cray's founder) who has joined MS to do exactly what you and other don't think MS is capable of...
True, it will take them few years to get there, but they will while you guys are wining...

FACE THE FACTS and get over it...
