SEEP is an experimental parallel data processing system that is being developed by the Large-Scale Distributed Systems (LSDS) research group (http://lsds.doc.ic.ac.uk) at Imperial College London. It is licsensed under EPL (Eclipse Public License). The SEEP system is under heavy development and should be considered an alpha release. This is not considered a "stable" branch. Further details on SEEP, including papers that explain the underlying model can be found at the project website: http://lsds.doc.ic.ac.uk/projects/SEEP The SEEP system consists of two modules, the runtime system (seep-system) and a compiler (java2sdg). Below is some information regarding how to build the system and modules. BUILDING: ##################### The project follows the standard Maven directory structure, with two differentiated modules, seep-system and seep-java2sdg. There are two options to build the SEEP system: Option 1, single jar (recommended) -- run: mvn clean compile assembly:single This produces one jar with all dependencies included. Option 2, without dependencies -- to compile it: mvn -DskipTests package In this case, ensure that the classpath includes the dependencies. You can alternatively build only individual modules, by running the same options above inside seep-system or seep-java2sdg, respectively. ************ seep-system ************ RUNNING: ######################### The system requires one master node and N worker nodes (one worker node per Operator). First set the IP address of the master node in "mainAddr" inside config.properties and build the SEEP system. Next run the master in the designated node: java -jar Master where query.jar is the compiled query and the last parameter is the name of the base class, not a path. Finally run as many worker nodes as your query requires: java -jar Worker Local mode: To run the SEEP system in a single local machine, append a different port to each Worker node: java -jar Worker ************* seep-java2sdg ************* RUNNING: ########################### It is mandatory to indicate an input program, an output file name and a target (dot/seepjar) and the classpath to the driver program and its dependencies. Examples: java -jar -i Driver -t dot -o myOutput -cp examples/ The above code will process input program "Driver" using the dependencies in "examples/" to generate an output file "myOutput.dot".
