• The file scripts/clusterperf.py is the top-level driver that runs the performance benchmarks. It uses scripts/cluster.py to set up a RAMCloud cluster, then invokes the C++ program ClusterPerf on client machines to run benchmarks.
• You must first have compiled ClusterPerf ("make all" will do that).
• In addition, you must create a file scripts/localconfig.py that describes the machines available in your cluster. Here Below is a sample file:
  • Note: If you have rcres access, an internal RAMCloud utility, the hosts definition below is unnecessary; leaving host hosts blank (i.e. hosts = []) will cause the scripts to automatically use the machines locked by the current user in rcres. A custom list can still be defined, but it will be validated against servers locked by the user in rcres.

# This file customizes the cluster configuration for John Ousterhout.
# It is automatically included by config.py.
