RPiCluster: Another Raspberry Pi Cluster, With Neat Tricks
New submitter 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 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."
Not to diminish your achievements which are otherwise quite cool, but this novel approach to rack mounting is anything but. Quite possibly the single most important feature of a rack is ease of component access. By tying all components together with PCB standoffs you basically can't remove a single RPi if there's ever a pressing need.
If anything you've shown a novel way of cramming things together without the use of a rack.
