      The application itself if not going to run on the cluster. The cluster is simply going to be used as a "compute farm" for solving the datasets and models produced by the application.

      This is similar to what is happening in the animation industry. The LINUX boxes are simply going to "crunch" the numbers and feed the results back to an application running under Windows or high end UNIX workstations.

      For a cheap "compute farm" cluster, you can't beat Red Hat Advanced Server with Xenon's.

      We are planning to build a 16 node cluster next year for the same purpose as Chrysler. Again, the apps aren't running here, LS-Dyna, DynaForm, Hypermesh, FEMB etc ... will still all run on a UNIX/Windows workstation, but the solving will be done (very quickly) on a Red Hat cluster.

      It just rocks!
      • For a cheap "compute farm" cluster, you can't beat Red Hat Advanced Server with Xenon's.

        Sure you can, how about redhat iso's running on Athlon MP's (or soon Opterons). Free software on better price/performance hardware.
        • Ok, you win.. that beats it :)

          However, I try to throw some cash Red Hat's way every now and then so they keep making distros.

          Assume your cluster costs $50,000 to build (including the Giga-bit ethernet gear), you are only going to pay $l000 or less for the O/S.

          That's a great deal and a half. Also, that paultry $1,000 investment keeps you in patches plus, gets your a year of email install/configuration tech support.

          But, your solution is definately cheaper !

      Actually, what accounts for about 50% of the cost of any given new car in America are the taxes. I was stunned to find this out.
      • It depends very much on the car. A foreign SUV or light truck has a 33% tariff. And, there is a small luxury tax on something like a BMW. There are property taxes and sales tax on transportation.

        So it can add up, but that's if you're buying an imported BMW or Lexus SUV. If it's a small US car the taxes are minscule, even an American $50k SUV doesn't then it's only a few percent.

        There is also taxes on the workers income, and any profit, but that's going to depend a lot on the country it's made in and where it's made. I could believe the 50% figure on an SUV made in Germany, but not on a some car made in Mexico(no tariff) for a US company racking up losses not profits.

      See the links modded up to (5, informative) elsewhere. The general idea is that these days you buy a Linux CoW or Beowulf cluster instead of upgrading the ageing Cray. And for some reason it's still newsworthy, though people have been doing it for the better part of a decade now [beowulf.org].

        Keep in mind that the majority of the news sources (or "news sources" where appropriate) covering this story are, if not actual pro-Linux sources (like /.), at the very least computer news sources. Google News comes up with only about 10 hits for chrysler linux (compared to 726 for sniper arrests), so it's not like it's even been that widely covered so far; and this kind of business change actually is a newsworthy development in the computer industry.

        You'd see this as a news story from computer-themed news sources; it'd be a "feature" in mainstream or general news sources.

    • And how precisely are they going to save money ? And save money relative to what ? The old system ?

      The savings are probably compared to buying a comprably powerful system running a proprietary Unix. I'd assume that the biggest chunk of the savings is that they can run on (comparatively) cheap commodity hardware. This seems to be a very common reason for moving to Linux: it lets you run your old Unix software on much cheaper boxes.

    • lets see,

      A decade ago RISC workstations (mostly running Unix, although NT started coming online soon after) had a far better price/performance on floating point compute cycles than Intel x86. If you needed to solve problems beyond the capacity of RISC processors (then 20-50Mflops) for $10-20K you needed to move to Cray (vector) processors (200+Mflops / CPU) with costs running in the range of a million $US per cpu.

      Unfortunately crush analysis (and structural FEA in general) doesn't scale all that well on multi cpu systems (at 8 CPUs you might see 4x speedup). Thus if you really needed run this sort of solution (in less than a couple of months compute time) it was worth the cost of the Cray.

      5 years ago while Xeon began to eclipse RISC in showing the best price / performance numbers, Unix/RISC (usually using super-scalar architectures) systems scaled to the point of replacing the vector based systems and proprietary Unix clustering has been solid and scalable to an order of magnitude beyond what you could think of doing with NT/W2k.

      Today the 'sweet spot' in price/performance is definitely intel Xeon and as most of this code has been developed on Unix, Linux is easy to do, and Linux clustering is certainly good enough to manage these tasks.

      Of course it could be run on win32 but why?

      Where you see FUD here is beyond me.

    On the off chance that you actually read the article, you'll see that they're replacing Unix machines, not Windows, with Linux. This is a no-brainer, especially since their software is probably custom-developed and can easily be recompiled under GNU/Linux.
    • Somehow, there's this perception that if a business migrates from Unix to Linux, that it's not a victory, that it might as well not be reported.

      But, keep in mind, that very many of these Unix to Linux conversions may well have been, 5-7 years ago, Unix to NT conversions. Maybe more than half.

      What's happened in the past few years is that Linux has all but halted NT/2000/XP's growth in the server space. And, being a *nix advocate, I think that's good news.

    • Funny, I was just thinking about this. A reletive just lost a whole bunch of data, due to a in a software program. While cars require a bit of basic knowledge, and licensing, there is liability there. If ford builds Taurauses with defective ignition controle modules(true), and my cars stalls and gets hit in the middle of an accident, I can sue them. When my relative lost his data due to something that was not his fault, who's liable. No one.
      • That's right, you can't sue them. And you don't want to. The car industry is horribly regulated, pretty much since the Ford Pinto. Typical markups on computers these days are about 10%, compared to a standard 100% markup for other products. Some products such as cables, enjoy a 12x increase.

        If you had to pay for insurance for a powersupply failing, you'd be spending $5000 for a $2000 computer, although it'd certainly be more reliable. Of course, it wouldn't run as fast, plus you'd then have to invest $1000 into an OS... even Linux most certainly wouldn't be free (as in beer) if liability was an issue.
      • Who's liable?
        She is.

        This is why any data you care about must be backed up. If she didn't take proper precautions with her data, that's her fault. Being a newbie doesn't change that.
        Think about it kinda the same way as wearing your seatbelt.
        I can only feel so bad for a person who dies in a car accident if they weren't wearing their seatbelt and it's the same for lost data.
        Hard drives are mechanical devices, as a result, their relibility is crap compared to just about everying else in your computer. Software isn't perfect, there are always a few bugs in some software package you could possibly install that will hose your system if you're not careful.

        It's easy to protect your data if you understand how to use a computer, and if you don't, you should expect sub-optimal results from your computer use until you learn.
        This doesn't mean I'm going to call the person an idiot for loosing the data. (Heck, it probably took most of us a disk crash or two before we realized just how important backups are.) I'll just tell them that there are various ways of protecting your data, so if they care about not losing it, they should learn how to back things up.
    • Yeah, well most people grew up with a car so they had experiences with all those terms and ideas, so that generally doesn't happen.

    So wait a minute, you save money by using Linux? Are you telling me that the folks at MS are lying and that the TCO for Winodws isn't lower?

    I thought that paying $200 for every copy of Windows and regular forced "update fees" would be cheaper than buying one Debian GNU/Linux CD and then updating using apt for free.

    Are you telling me that a product which costs less and functions equivalently will actually save you money? That doesn't make any sense. Microsoft says it doesn't.

      Red herring. The article was about a migration to linux from a proprietary unix, not from Windows. Therefore, the only conclusion you can draw here is that linux saves you money over other unix operating systems. You can't make any conclusions about linux TCO vs. Windows TCO based on this article.

        Well, if it was well-known that TCO for a windows cluster would be lower than for a linux cluster on the same hardware, then they would certainly have bought a windows cluster instead. I don't think portability is a big problem here. Most numerical code is quite portable.

        Looking at windowsclusters.org, it seems that most project there are using windows simply because MS agreed to supply both hardware and software, en exchange for using windows instead of linux.

          Unless the code for linux simply needed a recompile and maybe some touch-ups, while the code for windows would need a whole new interface. It's easier to switch from unix to linux, which would mean that the windows solution would have to have a much lower TCO, which probably isn't the case (whether or not Windows TCO is lower than Linux TCO is an argument for a different topic, and needs well-defined rules about what duties the target machine(s) would be fulfilling). I'd guess that the decrease in costs from a Unix to Linux switch would be sufficient enough that no investigation about a Windows switch would've been made unless a Microsoft account manager was working with them. Especially if porting the software was trivial when moving to Linux.


    • Too bad they replaced expensive UNIX computers with Linux ones. Same ole' same ole' around business these days. Hardly news worthy. Maybe in the Wall Street Journal but not a news for nerds/stuff that matters.
  • Well of course they're going to use linux.
    Can you imagine the price of all those new Windows XP licences they would have to buy to replace all those damaged computers?

      Chrysler is a big company, so they certainly have many projects going on at the same time. By centralizing on one big cluster they can increase utilization compared to each department needing simulation capabilities having its own minicluster. So what the article probably means is that at the same time they can run 18 different simulations each using on average 12 cpus (108*2/18).

      It's the same on (almost) all supercomputers. They have lots of users, but most users don't use that many cpus for their jobs. Take me, for example. On the supercomputer where I have an account there are 512 power4 cpus. Usually I use 8 or 16 cpus for my simulations, and so do almost all the other people using the same machine. About the only time the entire supercomputer is reserved for one job is when they're benchmarking it, which as you certainly can imagine isn't done so often.
  • Three developers were driving down the road when their car stops dead.

    They sit in the car and the Unix developer sayes "I think it's a problem with the core of the car, the engine. It can probably be fixed with a little bit of tinkering."

    The Apple developer sayes "No, I think that what ever is wrong must be a proprietary problem that we shouldn't mess with. Let's just have it towed to the manufacturer and wait until they fix it."

    Then the Windows developer spoke up and said "Wait...lets close all the windows, get out of the car, get back into the car and open the windows again, that'll fix it."

  • I thought the advantage that Linux brought was that it crashed LESS than the "other" brand software...
  • OK so they're using Linux to simulate car crashes, what will they use to simulate profits?

    I think Enron used Windows.
  • Although the article doesn't really elaborate you can see that the savings are in the choice of hardware. The article did not reveal what previous hardware was used however the mention of unix implies that it was probably and SGI cluster. A quick little search on google revealed an article [tenlinks.com] where Chrysler had previously using a SGI cluster consisting of a 126 node MIPS R14000 architecture running a 600 MHz. SGI is notoriously expensive and the custom hardware that is described in the article would represent a considerable cost savings.

    Or maybe we'll see a Apple Switch Ad that features Crash Tests...

    I was testing a car crash on the PC and it was like beeeeep beep beep beep beep beeeep! And then like half of my crash test was gone, and I was like unnnhhh...? It devoured my crash test.

    It was a really good test. And then I had to test it again and I had to do it fast so it wasn't as good.

    It's kind of...

    a bummer.
