RPiCluster: Another Raspberry Pi Cluster, With Neat Tricks

[wraggster]

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 (http://coen.boisestate.edu/ece/raspberry-pi/) is the result. I've written an informal document on why I built the RPiCluster, how it was built, and how it performs (http://coen.boisestate.edu/ece/files/2013/05/Rasp.-Pi.pdf) as compared to other platforms. I also put together a YouTube video of it running an MPI parallel program (http://www.youtube.com/watch?v=i_r3z1jYHAc&feature=youtu.be) 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 Slashdot community might be interested in this build as I believe it is a novel approach to the rack mounting and power management of RPis."
