Large Hadron Collider - powered by Linux From the "tearing the fabric of space-time" files:
The most powerful physics project in the history of the known universe - The $10 Billion Large Hadron Collider (LHC)- shot its first light speed beam this morning around its 27 km circuit. Beyond the 20 years it took to build and half of all the world's astrophysicists, it also takes another key ingredient to make LHC work -- Linux. CERN which is the organization that runs the LHC project is using something called CernVM which is is custom Linux distribution. According to VMware, CernVM runs inside of VMware virtual machines that include PC and Macs across a grid that encompases the power of approximately 40,000 CPUs and some 15 petabytes of data a year. CERN itself is no stranger to Linux and is one of the lead backers of the Scientific Linux distribution, which is a recompiled version of Red Hat Enterprise Linux. **UPDATED** Got a comment (listed below) from a commenter with an IP within CERN that writes,".. the primary configuration for machines in the LHC computing grid (http://lcg.web.cern.ch/LCG/) is based on Scientific Linux distribution running directly on the hardware. This grid is used to receive and distribute the 15PB of data across the 100,000s of CPUs across the world" ** Considering that the LHC, according to some, could be powerful enough to destroy the Earth, create a blackhole or rip a hole in the fabric of space itself, it is somewhat re-assuring that at least some of the key software behind it is not at risk from the blue screen of death. 1 TrackBacksListed below are links to blogs that reference this entry: Large Hadron Collider - powered by Linux.

How far can you go with open-source software? Quite a ways, apparently: Beyond the 20 years it took to build and half of all the world’s astrophysicists, it also takes another key ingredient to make [the Large Hadron Collider] work — Linu... Read More 19 CommentsLeave a comment |

GNU/Linux rules where it matters. Cause science ain't got no borders or barriers and GNU/Linux is steeped in the same. Bravo GNU/Linux!
Considering that the LHC, according to some, could be powerful enough to destroy the Earth
Not by anyone with their head screwed on straight.
Please stop propagating the myth that the LHC can somehow "destroy the earth". People are now receiving death threats over this idiotic media induced nonsense.

You are right! Even if it can destroy the Earth, nobody will ever know :)
O! Rly?
In photos from LHC command centre we can see Windows screens on monitors. So Windows takes care of Linux to protect LHC against failure.
While VMware is in use (http://www.vmware.com/company/news/releases/cern.html), the primary configuration for machines in the LHC computing grid (http://lcg.web.cern.ch/LCG/) is based on Scientific Linux distribution running directly on the hardware. This grid is used to receive and distribute the 15PB of data across the 100,000s of CPUs across the world.
LHC could form black holes that eat the planet so the researchers choose Linux not Windows to control it. :D
The Earth gets bombarded daily by cosmic particles that have greater energy than the LHC can accelerate particles to.
The Universe is already creating everything we can create with the LHC, and it does not result in black holes swallowing things.
Someone in India killed herself because she thought the world was going to end.
Erik said: 'Not by anyone with their head screwed on straight.' You mean the same people that developed nuclear fission devices for peace? Some people are really really gullible.
I work for CERN specially ATLAS, and yes we use scientific Linux (Red hat based) in all our tasks. the main data acquisition program runs in a Linux machines as well as a lot of infrastructure servers.
I work for CMS and yes, we luv linux =)

Please Zenn... Show us the pics of Window$ screens??? I have a Ubuntu Linux background on my Win PC at the office... Drives the boss crazy... ;)
I Luv my Linux boxes at home!!!
That's why we use Scientific Linux... and RHEL
Well, if it matters at all, the indicated website for the LHC computing grid is running IIS
as far as I know there are no computer clusters (supercomputers) in the entire world which run on windows. linux/unix IS the standard in science and there are several reasons for that: first reliability, linux is more reliable that windows.
second you can use a linux box remotely as if you were present in front of the machine, that means that scientist from all over the world can be working remotely without being actually in the laboratories.
third, when you do scientific computing a graphical interface is at best a nuisance and finally, this specific market is so small that has no interest for microsoft.
O! Rly?
Yes, rly!

clearly shows a Scientific Linux login screen.
There are a lot of scientific apps that don't have Linux versions, so they will have to run both OSes.
This is the most powerful and the largest project in the history of human science, which has shaken the head of the whole world, with it's life taking threats. But everything went fine.
Moreover, a TV news channel claimed that the machine stopped working just after a few hours of it started. If this is right, it's a matter of pity.
I think these are all such rumours are meant to spoil the status of biggest machine ever :)
It is said that the large hadron collider had been stopped working only after a few hours of it's start, is it true ? Was there any problem in the machine ?
