• Building the framework

Using ant build file. From root, $ ant compile (SCALA_HOME must be set to Scala home directory, i.e. /opt/local/share/scala

OLD WAY: $ scalac -d classes src/main/scala/ProcessingParallel.scala src/main/scala/Worker.scala

• Building the PageRank example

$ scalac -cp classes -d classes src/main/scala/PageRankParallel.scala src/main/scala/GraphReader.scala

• Running the PageRank example

Command-line arguments: #iterations datadir #pages $ scala -cp classes processing.parallel.PageRank 10 data/ 2000

Expected output:

Reading wikipedia graph from file... #vertices: 14672 Building page title map...
