Abstract in Portuguese
Esta dissertação apresenta uma proposta de um simulador de modelos de larga escala para o Ambiente de Simulação Distribuída Automático (ASDA), uma ferramenta que facilita a utilização e o desenvolvimento de simulação distribuída e que vem sendo objeto de pesquisas e estudos no Laboratório de Sistemas Distribuídos e Programação Concorrente (LaSDPC) do ICMC-USP. Tal simulador permite ao ASDA a construção de modelos e programas que simulam modelos de redes de filas de larga escala, operações estas que tornam a ferramenta ainda mais completa. O simulador é baseado no padrão público para simulação distribuída de larga escala denominado Scalable Simulation Framework (SSF). O protótipo do simulador desenvolvido é constituído de um programa cliente-servidor, mas podem ser observados três componentes principais: um compilador, que traduz os modelos escritos em linguagem de modelagem para linguagem C++; o módulo SSF que define a API utilizada pelos programas de simulação; e um módulo de execução, que executa os programas de simulação, analisa os resultados e os repassa para um gerador de relatórios. O simulador contribui ainda com mais estudos acerca de simulação, simulação distribuída e modelagem de sistemas utilizando as ferramentas desenvolvidas pelo grupo

Abstract in English
This dissertation presents a proposal for a large-scale model simulator, that is integrated into the Automatic Distributed Simulation Environment (ASDA), a tool that supports the development of distributed simulation, and that has been under studies and investigations in the Laboratory of Distributed Systems and Concurrent Programming at ICMC-USP. The proposed simulator allows ASDA to support the development of models and programs that simulates large-scale queuing models, making ASDA more complete and efficient. The simulator is based on a public standard for large-scale distributed simulation named Scalable Simulation Framework (SSF). The simulator prototype that was developed is a client-server program in which we can observe three main components: one compiler, that translates the models written in a modeling language to a simulation program, written in C++ programming language; the SSF library, that defines the API that is used by the simulation programs; and a runtime environment, which runs the simulation programs, analyzes the results and sends the information to a report builder. The simulator prototype also aggregates to the simulation community more studies regarding simulation, distributed simulation, systems modelling using the internal tools developed by our group
