Chrysler Adopts Linux For Vehicle Simulations
eMilkshake writes "According to this ComputerWorld article, Chrysler is adopting Linux for vehicle crash testing. According to the article, 'the new system is expected to improve simulation performance by 20%, while saving about 40% in costs....'" Insert knee-jerk reaction joke about computers and crashing here.
What OS will the crash test dummies run?

HelpLine: "General Motors HelpLine, how can I help you?"
Customer: "I got in my car and closed the door and nothing happened!"
HelpLine: "Did you put the key in the ignition slot and turn it?"
Customer: "What's an ignition?"
HelpLine: "It's a starter motor that draws current from your battery
and turns over the engine."
Customer: "Ignition?Motor?Battery?Engine?How come I have to
know all these technical terms just to use my car?"
In the name of efficiency I've decided to combine all of these exceedingly clever jokes into one package!

Headline, six months from now:
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.
BeOSYour car goes faster, looks better, draws amazed stares everywhere you go, and has amazing preformance. Yet, when you try to fill it up, you find that it is incompatable with almost all know gas products.
Once
There were these guys who
Thought that using Linux would
Improve their product's safety
And when
they fin'ly did it
They found
Gates had set fire to their work
He said that it was because
The Sherman act had smacked him
sooooo hard

Ah, the good ol' Crash Test Dummies...we hardly knew ye.
We now have confirmed reports from an informed Orange County minister that Ethel is still an active communist.
And how precisely are they going to save money ? And save money relative to what ? The old system ? (I kind of doubt it) The same hardware system with a proprietay OS ? Maintenance costs ?
This article has all the characteristics of a "negative" FUD.

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.

,000 for this car!Now you tell me that
Customer: "My car ran fine for a week and now it won't go anywhere!"
HelpLine: "Is the gas tank empty?"
Customer: "Huh?How do I know?"
HelpLine: "There's a little gauge on the front panel with a needle
and markings from 'E' to 'F'.Where is the needle
pointing?"
Customer: "It's pointing to 'E'.What does that mean?"
HelpLine: "It means you have to visit a gasoline vendor and purchase
some more gasoline.You can install it yourself or pay
the vendor to install it for you."
Customer: "What?I paid
I have to keep buying more components?I want a car that
comes with everything built in!"
HelpLine: "General Motors HelpLine, how can I help you?"
Customer: "Your cars suck!"
HelpLine: "What's wrong?"
Customer: "It crashed, that's what wrong!"
HelpLine: "What were you doing?"
Customer: "I wanted to run faster, so I pushed the accelerator pedal
all the way to the floor.It worked for a while and then
it crashed and it won't start now!
HelpLine: "It's your responsibility if you misuse the product.What
do you expect us to do about it?"
Customer: "I want you to send me one of the latest version that
doesn't crash any more!"
HelpLine: "General Motors HelpLine, how can I help you?"
Customer: "Hi, I just bought my first car, and I chose your car
because it has automatic transmission, cruise control,
power steering, power brakes, and power door locks."
HelpLine: "Thanks for buying our car.How can I help you?"
Customer: "How do I work it?"
HelpLine: "Do you know how to drive?"
Customer: "Do I know how to what?"
HelpLine: "Do you know how to drive?"
Customer: "I'm not a technical person.I just want to go places
in my car!"
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.
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.
Due to pressure from the FSF, since Linux was used as part of the car production process, GM will be forced to release the 2003 GNU/Taurus.

...just kidding.
It won't be funny, but watch, someone will do it anyway
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?
The next release of Tux Racer will have improved front and rear crumple zones, wing mounted side airbags, and will meet California emission standards.

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.

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!

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.

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.
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.
