Motivation for building a Supercomputer

What was our motivation to build such a big Beowulf cluster? Well, there are different reasons, here are some:

Need for computing power
Low price and high power
Adaptability to our needs
Technological Challenge
Additional qualification for our students

Need for computing power

In science there is an increasing need for computing power. The classical way is to apply for an account on a supercomputer of a national computing center, for example Jülich. However, than you have to share this big, big computer with a lot of people. Your job has to wait a long time in the queue, until it is processed. With the aim of having supercomputer power in for our groups we planned Tina.

Low price and high power

Beowulfs are the best way to get a lot of GFlops for your money if you can parallelize your code. But why are commercial supercomputers so expensive in contrast to the "cheap" beowulfs? If you buy one of these computers, you spend most of your money for an high-bandwidth/low-latency network. If you don't need this, then you should choose a beowulf.

Adaptability to our needs

If you build a beowulf cluster, you can optimize the design according to your needs. Memory, CPU, hard-disk, network, everything can be fit to your needs.

Technological Challenge

Until now, there are not too many big beowulf clusters like Tina or CLIC in Germany. Building and running of such a computer is a big challenge. Sharing information is one of the basic ideas of LINUX/Gnu/Beowulf, so we will share our experiences with the community.

Additional qualification for our students

We are offering lectures about parallel computing. Our students can collect some additional experiences, if they can "play around" on a big supercomputer.

Fun

Hey, it's fun, really. Get some old PCs, get a cheap hub, a few cable, a penguin and enjoy your private supercomputer.
