Interactive Data Analysis Cluster

• The nodes in this cluster need to have:

  • Excellent CPU performance
  • Large memories (to cache as much data as possible)
  • Lots of local high performance disk (to have fast access to the data)
  • High performance, low latency, switched, inter-node networking (for efficient interprocess communication)

• The cluster size is constrained by Amdahl's law to, typically, 8 to 12 nodes (depending on the network performance and amount of interprocess communication).
