A Cluster of Raspberry Pi

At Boise State University, a Beowulf cluster exists in the “MetaGeek Lab” (or Onyx Lab), which is run by the Computer Science Department.  The Onyx cluster currently consists of 32 processors, or nodes, each of which has a 3.1GHz Intel processor and 8GB of RAM, allowing substantial parallel processing capability. 

The cost for an RPi with an 8GB SD memory card is about $45, making the RPi platform one of the cheapest ways to create a cluster of 32 nodes. For comparison, each node in the Onyx cluster cost somewhere between $1,000 and $1,500. So, for close to the cost of one PC-based node, Kiepert was able to create an entire 32 node RPi cluster that requires less power than a single node in the Onyx cluster.
