[Beowulf] Redmond is at it, again

For some people, me being one of them, this is a HUGE threat. Let me
explain.

Redhat, Suse, etc. have gone to a per-CPU price for license
and support driving up the costs of installing the OS on a cluster.
In fact, the last quote I got for a 72 node cluster averaged about
$400 a node! Now management has started to compare this price
to Windows and guess what? - Windows is cheaper on a per
node basis. This includes purchasing and support! We already
have a massive license with MS so we get Windows pretty
cheap, but I can get Windows myself cheaper than $400 a node.
We started to talk to management about the support costs, etc.
but they argue that they already have a whole bunch of admins
trained in Windows so support costs should be low (I tried to
explain the difference between admining a cluster and admining
a Windows server). Plus we have an infrastructure to push
updates to Windows machines, so they though updates would
be a no-brainer as well.

At the ClusterWorld conference I tried to talk to various distro
vendors about pricing, but they weren't listening. I don't mind
paying a relatively small fee to purchase a distro, but paying a
support costs for each CPU is nuts! If I have a problem on one
node, I have a problem on ALL nodes. The distro companies
have yet to understand this. Novell is starting to come around
a bit, but they still aren't there yet.

We are encouraging cluster vendors to support at least one
open distro. That way we aren't held hostage to these companies
that don't understand HPC. I don't know if we're making any
head way, but I constantly hope we are. We're also trying to
push IT management into "approving" a couple of open distros,
but they are reluctant because they don't see a company behind
them (they insist on the "one throat to choke" model of support).
However, I'm still hopefully.

If you work for a disro company and you are reading this,
all I can say is, WAKE UP! You are going down the tubes fast
in the HPC market. If you work for a cluster vendor and you are
reading this, please push your management hard to adopt at
least one open distro. We'll pay for support for it, but not using
the current pricing scheme that the Redhat's, Suse, etc. are
charging.

If you work for a company that sells commercial software for
Linux (e.g. compilers, MPI, etc.), please support more than
RHEL and SLES! Think seriously about supporting an open
distro and also supporting a kernel/glibc combo.

I'm sure I'm not the only one who feels this way. Let's tell the
distro companies that we won't stand for it!

Thanks!

Jeff

>High-performance computing once required massive, expensive, exotic machines

>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

>performing calculations on an Excel spreadsheet, said David Lifka, chief

>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."

>better support for very large databases and for running on clustered systems.

>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."
