Kurt showed a picture of this in his last BLU talk I believe... http://coen.boisestate.edu/ece/raspberry-pi/
In the process of developing a novel data sharing system, Kiepert became convinced that the best way to test his ideas was to simulate them on a Beowulf cluster. A Beowulf cluster is a group of computers, usually identical, that are networked together in order to share the task of processing complex problems. ... Kiepert decided to build his own Beowulf cluster using RPis. Not only were the RPi's unique features for controlling simple hardware very useful, but the cost of creating the cluster was incredibly low. 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. ... Perhaps the biggest downside is that an RPi is nowhere near as powerful as a desktop PC. Also, because of the limited processing capability, the RPiCluster will not reliably support multiple users simultaneously. However, Kiepert believes these drawbacks do not have a negative impact on his current research. And a video showing it off: https://www.youtube.com/watch?v=i_r3z1jYHAc&feature=youtube_gdata_player Ignoring the issue of whether this is worth doing (as Kurt pointed out, the performance of a Pi makes this somewhat pointless, though might make sense if your objective is to test clustering functionality rather than performance), I've yet to see a Pi cluster with a mechanical design that allows you to easily extract/replace an individual Pi. -Tom _______________________________________________ Hardwarehacking mailing list [email protected] http://lists.blu.org/mailman/listinfo/hardwarehacking
