Linux: It doesn't get any faster

The Windows' fan club likes to point out that Windows is far more popular than Linux. The reason for that has nothing to do with quality and everything to do with monopoly. Nothing shows that better than the semi-annual TOP500 list of the world's most powerful supercomputers. In the latest ranking, where performance is everything and nothing else matters, Windows is stalled out at the starting line, and Linux is lapping the field.

Specifically, Linux has increased its already substantial supercomputer market share to 88.6%. Linux is followed by hybrid Unix/Linux systems with 5.8%; Unix, mostly IBM's AIX, with 4.4%; and running close to last, Windows HPC (high-performance computing) with 1%. Only BSD, with a single representative on the list, trails Windows.

In the lead at the number 1 spot with 1.105 petaflop/s (quadrillions of floating point operations per second) is the Los Alamos National Laboratory Roadrunner system by IBM. Roadrunner was the first system, to break the petaflop/s Linpack barrier in June 2008.

How fast is that? According to the Department of Energy, which paid for the Roadrunner, "One petaflop is 1,000 trillion operations per second. To put this into perspective, if each of the 6 billion people on earth had a hand calculator and worked together on a calculation 24 hours per day, 365 days a year, it would take 46 years to do what Roadrunner would do in one day."

And, of course, the Roadrunner is fueled by Linux. In fact, all the top ten run Linux.

The hardware the supercomputers run on is quickly shifting over to multi-core processors. In this latest ranking, only four supercomputers still use single-core CPUs. Quad-core processor-based systems are found in 383 systems, while 102 systems are using dual-core processors. In addition, four supercomputers are now using IBM's Sony PlayStation 3 processor with 9 cores. Yes, that's right, top of the line supercomputers use the same top of the line processors found in PlayStations. Neat isn't it?

Most of the supercomputer processors though come from Intel. To be exact, 399 systems, 79.8% are Intel. IBM Power processors come in second with 55 systems, 11% with AMD Opteron family with 43 systems in the third spot.

Regardless of the processor, one thing isn't just staying the same, it's actually growing, and that's Linux in supercomputers. When being the fastest of the fast is all that matters, Linux isn't just winning, it's extending its lead.

What People Are Saying

What distro?

What distro of Linux are all these supercomputers running?

Chicken and egg

The fact that Windows is run on most PCs is a chicken and egg problem. Windows runs on most PCs, so software developers usually only develop for Windows. Because most system only works on Windows, people run Windows on their PC.

There is a lot of Linux software out there, but it isn't what the mainstream wants to run. They want MS office, Photoshop, etc. Having something that does almost the same isn't good enough.

It's very unlikely for the public to break this cycle. The software houses have to make revenue and can't be asked to put so much time into such a small percent of the market.

I believe there is only one solution. And that is to make Windows (and/or Mac) software work on Linux flawlessly. A project like wine should get a for more prominent place and should be integrated fully into gnome/kde, having the applications look and function the same as native apps.

The chicken came before the egg

You see a chicken and egg problem, but you are looking from the wrong perspective. The chicken definitely came first, in this case. Microsoft "Leveraged" (coerced) OEM's into exclusivity deals years ago. Why did they do that? Not for the ~$20 profit on each unit sold. That was nice, but it was a short term benefit. The REAL benefit is, today's generation grew up with Microsoft, and it's pretty much all that they know. Today's generation wants Microsoft, because they don't know any better. It is for this very same reason that Microsoft is quite happy with the mass pirating of Windows (and MS Office) in 3rd world countries. They WANT people to learn MS, and to become reliant on MS. The chicken laid the egg years ago.

The Cathedral, The Bazaar, And The Reseller

Hello Steven:

Do you remember when you wrote the following paragraph?

"It's not just an NT show, though. NetWare does SMP. Linux does SMP. And the commercial Reduced Instruction Set Computer (RISC) Unixes, especially IBM's AIX, does it best of all. Indeed, in cases where someone is bound and determined that SMP is the be-all and end-all of computing, a reseller would do well to set them up with an IBM RS/6000 and AIX solution."

Well, it's been more than 10 years since you announced "I've been accused of being a linux bigot by Windows fans..."

You even wrote your own "The Cathedral, The Bazaar, And The Reseller".

I've updated your page at http://tinyurl.com/lov6bd

I've also made it easier for people to learn about you and SCO via Google. Just search Google for SCO and Steven J. Vaughan-Nichols .

Cheers!

Interesting how no matter what the subject -

No matter what the subject, the conversation descends into Monopoly, anti-microsoft rhetoric, etc.

Unfortunately complaining here won't do you any good. It might make you feel better, but you won't accomplish anything.

Many of us old farts remember the days before Microsoft DOS. It was a painful experience. There might be 10 PCs in an office running 10 operating systems that were incompatible with each other. Like it or not, MS brought stability.

that stability is extrememly important for the business world. Change is something like IT is expensive and scared the managers half to death. that stability provided the foundation for computers to be useful.

Linux was present for lots of these activities, but was too unstable at the time to be of interest. MS was first and most stable.

Now after 18 years, Linux is finally somewhat grown up. Unfortunately, Linux has to get through the existing, hard won stability.

Microsoft rides on that stability and the related market inertia.

One must ask what reason people have to leave that nice safe stable world of Windows on the desktop?

Windows is slow, cludgy, etc. The windows interface does meet user needs. That's all that matters.

No way Windows will ever make the "Best" super computer in the world. Yet, it survives on the desktop rather nicely. All the technological advances really don't matter anymore. Windows is sufficient.

Until Linux provides sufficient reasons to convince the masses to move from Windows desktop, Linux on the desktop is a small sideline.

Perhaps SJVN should use his clout for pushing Linux forward instead of constantly harranging Windows. It just wastes time and energy repeating what we all know.

The conversation descends into Anti-MS disputes

One of the wonderful things that happened to the world was the introduction of Minix, Linux and BSD.

Apple was able to put a wrapper around BSD (a Unix derivative) and loo-- The Mac and more.

Red Hat took linux and the world is grateful, due to the high quality of the product and the ubiquitous nature of linux (can run on any hardware).

Microsoft recognized a PC phenomenon and developped XP, Vista and soon, Windows 7 for the PC. But... as hardware prices drop, and performance increases, MS software increases or holds itself steady.

University students cannot advance their knowledge with closed source software, so the benefit to them is to have BSD, Linux and Minux code, as well as a few other systems to handle multi-processor based operating systems. All of this generates a great affection for Microsoft, as Anonymous reported.

And the same applies to databases such as MySql, Postgress Sql, SqlLight as alternatives to propriatory closed source systems.

Now we are moving to business systems, and here again, Open Source is winning the battle. I refer you to OpenBravo ERP which compares favorably to Navision, Sugar CRM, another winner, and a few other systems.

I have XP, I will also get Windows 7, since the approximate dollar a day cost is something I can afford. But, there is a billion pcs out there where people cannot afford the dollar a day cost. What choices do they have.

That is the problem. Software should not be a major expense and that is the way of the future. SaaS will be the next utility enterprise. Our gas, water, electricity, is purchased at reasonable cost from utilities, I see software being delivered the same way.

No, it is not MS bashing, it is recognizing that one era is over, and another is starting. The Model-T gave birth to Dodge, (Chrysler), General Motors, and so many competitors. Same will occur with software because it has to occur. And I believe that XML and html5 and some other system file designs will cause it to happen.

Microsoft has never brought

Microsoft has never brought "stability" to computing. It has brought homogeneity. Before Windows, we may have been running a variety of operating systems, but they generally shared the common traits of reliability and actual stability.

Now I reboot my Windows (work) machine every day to avoid the inevitable slowdowns and lockups I've gotten in the trade. OK, to be fair, maybe I don't have to do it *every* day. I could probably make it up to three days before it becomes unusable. But by reboot every morning, I can *usually* get through an entire day of work. That work, btw, is generally done via Cygwin on the *real* computers.

We don't reboot our AIX machines or our Linux machines or our OS X machines every day because they're stable.

Amen

Homogeneity is exactly right. And in the anon MS shill's example, why were there 10 pc's in an office that were incompatible? That's right, because of proprietary systems! Had the vendors of the time seen beyond their short-sighted protectionism, the market wouldn't have had to have chosen just one -- and we would be enjoying a market of healthy competition, OS stability, and interoperability. MS isn't the answer, it is the inevitable result of the problem poorly handled.

"Popular" is the wrong word

Windows Popular?


By the same measurement, Death and Taxes are extremely popular! Way more popular than any US President or any flavor if ice cream! Therefore, we can safely conclude that everyone loves death and taxes.



Please do not let this go unchallenged. When windows fanboys say Windows is "Popular", point this out. Windows has a Monopoly. That is not the same thing as popularity. Windows also has a huge installed base both in number of units and as a percentage. But that is a result of Monopoly not Popularity -- just as Death and Taxes are the choice of almost 100% of every human who has ever lived!

"That word that you keep using...

... -- I do not think it means what you think it means."

The word you're looking for (instead of "popular") is "ubiquitous"

u⋅biq⋅ui⋅tousadjective
existing or being everywhere, esp. at the same time; omnipresent: ubiquitous fog; ubiquitous little ants.
