| Debian Linux cluster beats supercomputer in tsunami warnings
2008-03-13 by Andrew hendry: "Our ICT group came out with Debian as the most stable in servers, especially when things are being done pretty much in automatic mode. In our workstations the preference among programmers is Ubuntu, which is basically Debian-based," he said." |

| What CAN'T Linux Do?
2008-03-26 by Jack Wallen "A few weeks ago a colleague of mine sent me a link to a story about a man who clustered together sixteen Playstation 3s using Linux to simulate black holes (HERE'S THE LINK for those interested.) I had forgotten about this until yesterday when I was thinking 'What can't Linux do?' I know, I know, you're thinking: Alright fanboy, bring on your dogma. Not so. This isn't one of those pie in the sky, wishful thinking blog entries where I am going to go on to spout that Linux will, in fact: Cure cancer, solve global warming, fix the US economic crisis, and release the world from its dependency on oil..." |

| PelicanHPC GNU/Linux
PelicanHPC is a live CD image that let's you set up a high performance computing cluster in a few minutes. The frontend node (either a real computer or a virtual machine) boots from the CD image. The compute nodes boot by PXE, using the frontend node as the server. All of the nodes of the cluster get their filesystems from the same CD image, so it is guaranteed that all nodes run the the same software. The CD image is created by running a single script, which takes advantage of the Debian Live infrastructure. If you need to add packages, it is very easy to create a custom version by adding the package names to the script and then running it.
Historical note: Pelican works very much like ParallelKnoppix, and is the continuation of that project. Thanks to Debian Live, Pelican is much easier to maintain and customize than is ParallelKnoppix. I now recommend that new users start with Pelican. |

A computer cluster is a group of loosely coupled computers that work together closely so that in many respects they can be viewed as though they are a single computer. The components of a cluster are commonly, but not always, connected to each other through fast local area networks. Clusters are usually deployed to improve performance and/or availability over that provided by a single computer, while typically being much more cost-effective than single computers of comparable speed or availability.
Grid computing or grid clusters are a technology closely related to cluster computing. The key differences (by definitions which distinguish the two at all) between grids and traditional clusters are that grids connect collections of computers which do not fully trust each other, or which are geographically dispersed. Grids are thus more like a computing utility than like a single computer. In addition, grids typically support more heterogeneous collections than are commonly supported in clusters.
