Linux.com: I set up a two-node Beowulf cluster at my house one time, but back then I had no clue what to do with it. It's tough for an administrator to make effective use of a cluster, being that there's no usable parallelized password cracker that I know of. Now I'm in an environment where other people can make use of a cluster, and I volunteered to try to set one up using Rocks 3.2.0.
System administration and cluster administration are very different things. The tools are different, the problems are different (though many are related to system-level stuff that we can sink our teeth into), and the options for implementing a cluster are many and varied.
