RPiCluster: Yet Another Raspberry Pi-based Beowulf Cluster

TheJish writes: The RPiCluster is a 33-node Beowulf cluster built using Raspberry Pis (RPis). The RPiCluster is a little side project I worked on over the last couple months as part of my dissertation work at Boise State University. I had need of a cluster to run a distributed simulator I've been developing. The RPiCluster is the result. I've written an informal document on why I built the RPiCluster, how it was built, and how it performs as compared to other platforms. I also put together a YouTube video of it running an MPI parallel program I created to demo the RGB LEDs installed on each node as part of the build.

While there have certainly been larger RPi clusters put together recently, I figured the /. community might be interested in this build as I believe it is a novel approach to the rack mounting and power management of RPis.
