Following on from my blog “Race to the largest Raspberry Pi Cluster“, James J. Guthrie has built a 3 node cluster out of Raspberry Pi 2’s using 3 nodes, out performing the 64 node cluster.

The Iridis Pi has a peak CPU performance benchmark was around 1 GIGAFLOPS (floating point operations per second)

The cluster presented here is made of 3 second generation Pi’s (nodes) and has a peak performance of over 3 GIGAFLOPS.

A short paper on the cluster can be found at the link below.
