Testing on Beowulf

Modify the script used in this project or create your own script according to the following guidance.

• running sbt on different beowulf nodes may re-compile the code.
• We use sbt-assembly to package all requried files in a single jar, so that the benchmark application can be run as standard JAVA application
• the bash script for running the benchmark are given at ***

$ sbt "project scalabilityBeowulf" "assembly"

• start node

$ java -cp ./scalabilityBeowulf/target/scala-2.10/scalabilityBeowulf-assembly-0.1-SNAPSHOT.jar scalabilityBeowulf.takka.TAkkaWorkerNode 01

• run bench
