24 Node Raspberry Pi Cluster

Former Member over 12 years ago

Details about the 24 node cluster we built are included in the following links

For comparison, there is another recent 24-node RPi cluster report at:

http://eclipsejpa.blogspot.com/2012/11/java-7-se-parallel-processing-cluster.html

It notes that the mpi pi-calculation benchmark scales very badly, running slower
with each additional node.
1 node: wall clock time = 0.017286
2 node: wall clock time = 0.020435
4 node: wall clock time = 0.037727
6 node: wall clock time = 0.043331

This is the same benchmark that the University of Southampton used,
although their published results were for only two nodes, and omitted the timings.
