DMASON is a parallel version of the MASON library for writing and running simulations of Agent based simulation models.

Agent-based simulation models are an increasingly popular tool for research and management in many, different and diverse fields. In executing such simulations the “speed” is one of the most general and important issues. The traditional answer to this issue is to invest resources in deploying a dedicated installation of dedicated computers. D-MASON is a parallel version of the MASON, a library for writing and running Agent-Based simulations. D-MASON is designed to harness unused PCs for increased performances.

Why Distributed MASON?

Among the motivations to our focus on distributing the simulation on several machines, we can underline how the need for efficiency among the Agent-Based modeling tools is well recognized in literature: many reviews of state-of-the-art frameworks place “speed” upfront as one of the most general and important issues. While a consistent work has been done to allow the distribution of agents on several computing nodes, our approach here is different in principle: we want to introduce the distribution at the framework level, so that the scientists that use the framework (domain experts but with limited knowledge of computer programming and systems) can be unaware of such distribution.

Generate build without runs test suite:

$ mvn -Dmaven.test.skip=true clean package

Add additional library to repository

If you need a library not included in the DMASON repo, you can add it by including the Maven dependency in the pom.xml. If the library is 3rd-Party and is not available on public repository, you can put in the DMASON repository. The first step is generate the dependency Maven data, in the fallowing there is an example of that using the MASON library:

$  mvn install:install-file -DgroupId=it.isislab.dmason -DartifactId=mason.18.jar -Dversion=18 -Dfile=./repository/jars/mrjadapter-1.2.jar -Dpackaging=jar -DgeneratePom=true -DlocalRepositoryPath=./repository  -DcreateChecksum=true

After that you must put the output data in the repository folder of DMASON GitHub and add to pom.xml:
