DistSim

DistSim

DistSim is provides tools to define parameters of simulations, exectute them on various hosts in a LAN and collect the results in a database. The parameters, results and references to the code used to perform the simulations are kept in a central MySQL data base, so that little manual organization of data is required and all results of past simulations are easily accessible for comparison. DistSim consists of the following components:

• The simulation wrapper is a small program running on the hosts intended to execute the simulations. It regularly checks for changes in the database, fetches new simulation jobs and executes them.

• The object-relational mapping library is a helper library to simplify storing the results of simulations. It can save (almost) arbitrary java objects into the database using a simple persistence mapping.

• The configuration library provides routines to define simulations, groups of simulations and studies. It can be used to programmatically create simulations.

• The configuration library is also the back end for the configuration client, a swing GUI for defining parameters of simulations.
