Linux Claims 4 of the Top 5 Supercomputer Spots

Anonymous Coward writes to tell us that the November 2005 list of supercomputers has been published. Certainly something to note is that four of the top five use linux. Relatedly Multiflow writes "CNET is reporting that the number of supercomputers on the Top500 list which use Intel Itanium 2 microprocessors has fallen by almost 50% in the past year. While new higher performance Itanium chips are in the pipeline, the article reports that 64 bit Xeons and Opterons have increased their representation on Top500."

      Actually, it doesn't show that at all. Supercomputing is a very specialised niche use of hardware. Generally, this sort of software wants the operating system to get out of the way as much as possible and allow the fastest possible access to memory and processors and (depending on the situation) I/O systems. In the past major supercomputer applications have required very little operating system functionality to back them up.

      There is little comparison between specialised numerical supercomputing and general multi-processor mainframe use, which requires concurrent multiuser access to app servers, general filesystems, databases etc. This is where older OSes such as IBM operating systems and Solaris work very well, and where Linux is now making inroads.

      It is rather like comparing a formula one racing car to a truck. I agree that Linux is suited to both purposes, but working well in one environment does not indicate usefulness in another.

  12. Re:Oh but they are by Grishnakh · · Score: 5, Insightful

    There's probably at least two camps of Linux users, based on their belief on whether marketshare is important or not. I'm somewhere in the middle.

    On the one extreme is people who don't give a rat's ass if other people use it or not, or at least say this. On the other extreme is people who want global domination.

    The problem with the first extreme is that for the whole open-source concept to work, you have to have a critical mass of users so that you have a large enough base of developers (which are a subset of the users) to keep the project working. Since most open-source software isn't owned by corporations (though some is certainly supported to some extent by them), open-source requires a large number of users to help work on the various projects.

    The problem with the other extreme is that, in order to make Linux (as a group of distributions) a viable choice for all current Windows users, certain concessions and changes might have to be made, such as providing an API for closed-source drivers, removing features from the most popular software because it's "too flexible" for many users, standardizing on one desktop (GNOME or KDE), etc. Many powerful people in the open-source community don't like these things, and it's quite debatable whether they might end up hurting or destroying the open-source movement instead of helping it. (For instance, if it became easy to distribute closed-source drivers, then while Linux might become more popular initially, it might suffer from the same problem as Windows where companies release crappy drivers for their hardware, which makes Linux systems unreliable, and the companies refuse to help any open-source driver efforts).

    Personally, I don't want Linux to become a commercialized, closed-source OS with a few open-source bits, but all the important stuff closed as some companies are trying to do. I also don't care if "Aunt Tillie" uses it, as long as she doesn't ask me for free support for her Windows computer, so I don't really care about it becoming the dominant OS. What I do want is for it to gain enough marketshare so that it's taken seriously, most hardware is supported on it (by open-source drivers), most worthwhile application software is ported to it, and that there's enough business in it that the dominant distros can make very polished versions without any major shortcomings like we still see today. In a nutshell, I want to be able to use Linux at work and at home to do anything I need to do (including buying and using the latest TurboTax or AutoCAD, for instance), without ever running into any major problems because I don't use Windows. If Linux reached 50% marketshare, this dream would probably be realized. The Windows users could happily live with their BSODs, activations, client-access licenses, high license prices, etc., and me and the other Linux users could happily ignore all that crap without being hindered because some web site is "optimized" for IE, TurboTax doesn't have a Linux version, ATI cards have crap drivers for Linux, etc.

    Already, we're getting fairly close: certain types of hardware still have serious driver problems (video cards and WLAN adaptors), most lower-end commercial software does not have a Linux version (although much high-end software, such as that by MentorGraphics, Cadence, etc., does), and we still have serious problems with non-HTML-compliant websites. But on the plus side, we have a very reliable kernel and OS, we have very functional desktop environments (GNOME and KDE, and apps from one will work in the other), we have tons of free software to satisfy most of your needs both on the server and the desktop, and we have tons of drivers for most popular and also much older and obscure hardware. We're at the point now where you can get a recent Linux distro and install it, easily and quickly, on the hardware of your choice, and probably not run into any problems at all. You'll get tons of included software (web browsers, CD burners, word processors, etc.), and be able to do just about anything you reasonably need to do with a computer, unless perhaps your raison d'etre is to play all the latest 3D PC games.

    Ie, there's books and ads for just about anything.

    All the time I see evangilism on how much better things would be if we all ran Linux. No viruses, no license fees, no crashes, etc, etc.

    Well, most evangilism is about Linux now. Yes, there are some idiots who believe there would be no viruses (history would disagree) or no crashes (there's crashes now, though thankfully having open source means it's more likely that once can find the cause if one's willing to do some work).

    There are a great many in the Linux community that seem to believe the ultimate Linux goal should be the domaination of the OS market.

    Cue the moron comment again. Fanatics tend to be like that. Just look at Apple fanatics.

    Of course non[e] are willing to change Linux in the ways needed for this, but they state it as a goal all the same.

    Well, some probably are actually. But you're right that the majority of fanatics aren't interested in changing Linux to meet the demands of the general public. To a certain extent I'm happy with that, since some of the demands of the general public are stupid (mostly, the removal of various security features to make it "easier"). Of course, working to solve those shortcomings that makes sense would make sense.

    Some people don't care about Linux market share, but many do, including most of Slashdot and some very notable figures.

    I care about Linux market share. I wouldn't try to claim to know what most (which I take to mean, a majority of) Slashdoters think. Now, yes, many (as in, a sizable number or percentage, but not necessarily a majority) Slashdoters care about Linux's market share (I'm going on the fact that I've seen several thousand comments by various people). But many care primarily because of the side effects of a Linux market share. That doesn't necessitate that they're out there evangelizing. It's hard to say, though, that they don't have something of a vested interest in insuring that there isn't a single company using their monopoly to interfere with the development, deployment, or sale of competing goods. So, again, I care about Linux market share. That doesn't mean I, or others, am an idiot who would try to push everyone towards it.

    I've often been berated because I won't switch, and told my reasons for refusing to do so are invalid.

    Perhaps you should try to ignore such people, just as you have to ignore any fanatic. It's virtually impossible to argue with a fanatic. It's best to simply drop the subject. Just like it's necessary at times to drop the subject about what happens to a person after they die, since some people don't like the "I don't know" as a complete answer.

    Anyway, user share only matters (for us) to the extent that we do not want to be excluded from doing something simply because we haven't enough users to be relevant. The actual number doesn't matter, only the effect that number has on consideration of our OS as a "first-class citizen".

    First of all, this is not the "OS wars" so much as the machine wars - these are all different machines, even if they do use different OSes - the only reason they have different OSes is because their OSes were written specifically with that machine in mind. This is no different today - you still can't run MS Windows on a Mac.
