Oracle JVM version "1.7.0_07"
Java(TM) SE Runtime Environment (build 1.7.0_07-b10)
Java HotSpot(TM) 64-Bit Server VM (build 23.3-b01, mixed mode)

4 JVMs were run, one for each node.

JVM switch specified was -Xmx12901m so it would consume roughly 80% of
memory overall.

Machine is x86-64 4-node, 64G of RAM, CPUs are E7-4807, 48 cores in
total with HT enabled.
