Chrysler Adopts Linux For Vehicle Simulations
eMilkshake writes "According to this ComputerWorld article, Chrysler is adopting Linux for vehicle crash testing.

After running a simulation on windows to simulate a simulation crash of their testing simulations.

The more I learn about the Internet, the more amazed I am that it works at all.
MS-DOS: You get in the car and try to remember where you put the keys.
WINDOWS: You get in the car and drive to the store very slowly, because attached to the back of the car is a freight train.
MAC SYSTEM 8: You get in the car to go to the store and the car drives you to church.
UNIX: You get in the car and type GREP STORE. After reaching 2000 mph en route, you arrive at the barber's shop.
WINDOWS NT: You get in the car and write a letter that says 'go to the store'. Then you get out of the car and nail the letter to the dashboard.
TALIGENT/PINK: You walk to the store with Ricardo Montalban who tells you how wonderful it will be when he can fly you to the store in his Learjet.
OS/2: After fuelling up with 6000 gallons of gas you get in the car and drive to the store with a motorcycle escort and a marching band in procession. Halfway there, the car blows up, killing everyone in town.
S/36 SSP: You get in the car and drive to the store. Halfway there you run out of gas. While walking the rest of the way you are run over by kids on mopeds.
AS/400: An attendant kicks you into the car and then drives you to the store where you watch everyone else buy filets mignon.

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.

It says the Linux solution saves 40% over the prior Unix solution, but it doesn't say what the prior solution is. Are the savings here really coming from using Linux, or just from using cheap commodity hardware clustered together?
...especially for a public announcement. I remember a while ago Microsoft was touting their big thing with how their clustering was going to out-do anything opensource with a few months, yet more and more large corporations, and not simply startups or new, tech-savvy ones, are adopting Linux or some other form of open source instead. I hope this demonstrates a continuing shift away from poorly written server code to something more viable and of better spec.
IBM had PL/1, with syntax worse than JOSS,
And everywhere the language went, it was a total loss...
Good point except for those particular applications were running on Unix before, not Windows.
This space intentionally left blank.
Seriously, they're not going to draw attention to their #1 competitor by smearing it, especially when most of their customer base has never even heard of it.
Four men rode in a car, a mechnical engineer, an electrical engineer, a chemical engineer, and a computer engineer. The car stalled out.
The mechnical engineer said it must be the pistons, let's repair them and we'll be okay.
The electrical engineer said it has to be the spark plugs, we'll replace them and be ready to roll.
The chemical engineer said it's got to be bad gas, we'll flush the system and be on our way.
They turned to the computer engineer. What do you think we should do?
Let's get out of the car and get back in.
So this might explain why the SGI Octane I just bought off eBay had chrysler.com nameservers referenced in it. /me wonders

That's not true for home users, though. That market will come eventually, but we'll see Linux on corporate desktops before it's widely used in the non-geek home market.

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.
Care to try again?
Err... yes!, Linux?, crash?, Crysler?, Linus doesn't write in linux-kernel for a few days... Oh my god, it's true. They hit Linus!!!

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.

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. Plus, you have to take drivers education class in most places in the US, so people are informed. Kids now a days have computers everywhere - at home, at school, on tv, etc. In a decade or so, a majority of these semi-stupid complaints will probably be replaced by more intelligen ones... like why do I shutdown my computer from the start men? ;)
[Yes, I realize this was for comic relief, but there was something else I thought was worth saying]

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.

I thought the advantage that Linux brought was that it crashed LESS than the "other" brand software...
You see? You see? Your stupid minds! Stupid! Stupid!
How about: BillGates goes out and purchases a Chrysler Lebaron. He drives off the lot and the car automatically crashes into a tree. He goes back to the lot and tells them what happened and they give him another one. This time he drives off the lot and the car immediately runs into a wall. He goes back to the dealer and the dealer says "I am sorry Mr. Gates, I don't know what is wrong with these cars". Bill replies, "Wrong, I don't know what you are talking about. They are running just perfectly".
Worst. Sig. Ever!
Just following up on this and other replies. It has been said several times that the parent of the parent is incorrect, and several people have asked why it was modded up.
I don't know why it was modded up, but I have moderator points, and I'm not going to mod it as overrated. I'm posting instead.
Moderation shouldn't be about correct or incorrect. It should be about improving the discussion. Its better to leave the post alone and reply to it, that way both view points can be expressed.
Leave the readers to make up their own minds, rather then censoring any views that you disagree with.
Democracy isn't about no one telling you what to do. It's about everyone telling you what to do.

OK so they're using Linux to simulate car crashes, what will they use to simulate profits?
I think Enron used Windows.
You could just have provided a link, you know. As opposed to cut'n'pasting this outdated document.
WINDOWS NT: You get in the car and write a letter that says 'go to the store'. Then you get out of the car and nail the letter to the dashboard.
WTF?!

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.
... will still all run on a UNIX/Windows workstation, but the solving will be done (very quickly) on a Red Hat cluster.
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
It just rocks!

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.
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.

so pick Linux, does any OS have more choices (JFS, XFS, ext3, Reiser) ?
Infuriate left and right
Aren't we past the point were Linux needs to be "adopted"? Is Linux an orphan that needs a home? Is Linux the red headed step child of operating systems? I think this shoud read "Linux Takes Over Chrysler (for vehicle simulations)".
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.
There are 4 boxes to use in the defense of liberty: soap, ballot, jury, ammo. Use in that order. Starting now.
That applies to any product, not just cars.
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 !
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.
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.
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.
As other have pointed out, the car is taxed at multiple stages of production (or rather the company that makes the car). Additionally, the 6% you quote is only the sales tax. There are luxury taxes (which suprisingly apply to many vehicles you wouldn't consider luxurious) and excise taxes. Additionally, you can expect, in many states to pay property taxes on the car. If someone buys a car for you, both you and them have to pay a gift tax (if the value is over $10,000 I believe).
