Abstract

This thesis proposes an automatic environment for the development of distributed simulation ASDA (Ambiente de Simulação Distribuída Automático (in Portuguese), whose main goal is to make easier the use and development of distributed simulation. The ASDA functionality makes it different from all other environments found in the literature. The ASDA has been specified through a modular diagram, composed of seven modules built with the help of the UML (Unified Modelling Language) tool, using three of its diagrams: use case, class and activity. ASDA users can define the distributed simulation by means of the specification of a new simulation program or the replication of a simulation program already developed. If the user chooses to develop a new simulation program, he must only provide the model and the parameters. The environment will then generate the simulation program code using the approach that provides the best performance considering the model and platform characteristics. Besides the specification, this thesis presents a prototype of the ASDA environment with the goal of showing its viability. Three modules have been implemented for the prototype, highlighting the Replication module, which uses the MRIP (Multiple Replication in Parallel) approach. Another contribution of this thesis is the definition of a set of guidelines to the utilization of the MRIP approach. The basis to define these procedures was the results obtained with the utilization of the Replication module (AU)
