Linux.com: So you need a lot of computing power but don't want to spend tens of thousands of dollars on a commercial cluster? Or maybe you just have a lot of machines sitting idle that you would like to put to good use? You can build a powerful and scalable Linux cluster using only free software and off-the-shelf components. Here's how.
To build our cluster we are going to use three pieces of software:
* Fedora Code 3
* DRBL (Diskless Remote Boot on Linux)
Fedora Core 3 will be our base distribution, since it's freely available and well supported by both DRBL and Condor. For the purposes of this tutorial we'll assume that you already have FC3 installed on the machine that is to become your server. The server machine will be responsible for storing and serving all the files necessary for the client machines to be able to work. It will also act as a firewall between the cluster and the outside world.
