“…Since the main reason for running a simulation on a distributed computer is to reduce the total computation time, the speedup is the most often used attribute for the performance of the distributed simulation (e.g., in Alian et al, 25 Bononi et al, 26 or Cavitt et al 27 ). 5 The performance of the distributed simulation is quite often investigated in relation to the size of the model (e.g., in Alian et al, 25 Djemame et al, 28 or Wegener et al 29 ) and the number of simulation processes (e.g., in Klefstad et al 3 or Lee et al 30 ). The number of used simulation processes usually depends on the number of nodes of the distributed computer.…”

A computer simulation of road traffic is a commonly used tool, which can help to manage constantly intensifying road traffic. It can help to analyze behavior of existing road traffic networks or to predict the behavior of new designed road traffic structures. There are several existing simulators designed or adapted to run in a distributed computing environment in order to achieve a faster execution. In this environment, the inter-process communication ensured by a high-level communication protocol is one of the main bottlenecks limiting the speed of the entire computation. Various high-level communication protocols can have various efficiency, applicability, and scalability. This paper describes an improved methodology for testing and assessment of high-level communication protocols for micro-scale (or microscopic) distributed road traffic simulations. The methodology investigates the dependencies of the communication protocols’ performance on various features of the simulation and enables to easily calculate score for each of the tested protocols. Using the scores, the tested protocols can be directly compared. This can be useful when designing or improving a distributed road traffic simulation as the best protocol can be used in this simulation to improve its performance (e.g., its speedup or communication time). The improved version of the methodology is an evolution of its original version. It newly incorporates the assessment of the error introduced into the simulation by lossy communication protocols and reduces overall number of performed tests. The improved methodology was tested using a case study assessing several communication protocols of our own design.

“…Os principais inconvenientes desta solução são custos relativamente elevados e uma abordagem de modelo centralizadora. Alguns pesquisadores propõem a criação e manutenção de uma lista global de eventos que deverão ocorrer (Chiola, Ferscha, 1993) (Djemame et al, 1998). A lista é por sua vez classificada e dividida entre os vários processadores.…”

Em função da capacidade computacional instalada e da estrutura dispersa de alguns sistemas produtivos, existe interesse em soluções de modelagem e simulação distribuída destes sistemas. Isso é considerado como um recurso fundamental para o projeto, implementação e melhoria de desempenho desses sistemas produtivos. A idéia é que por meio de simulações com o uso de computadores fisicamente dispersos, mas integrados através de uma rede de comunicação, pode-se avaliar o comportamento de sistemas em concepção e melhorar resultados de plantas existentes. Este trabalho propõe assim, um procedimento para a modelagem de sistemas produtivos em ambientes distribuídos. Esse procedimento foi aplicado com sucesso a alguns estudos de caso onde sua eficácia foi confirmada. Este trabalho envolve ainda a proposta de um algoritmo para o gerenciamento da simulação distribuída. Com o método de modelagem e o algoritmo de gerenciamento tem-se os principais elementos para a implementação prática de um simulador de sistemas produtivos dispersos.
Based on the existing computational capability and disperse infrastructure of some productive systems, there are interest for distributed modeling and simulation of these systems. These techniques are considered fundamental for design, implementation and performance improvement of productive systems. The approach is the simulation through the use of computers physically dispersed but integrated via a communication network to evaluate the behavior of systems still in conception level and also to improve the performance of existing plants. This work proposes a procedure for modeling of productive systems in distributed environment. This procedure was applied to case studies to confirm it effectiveness. The work includes an algorithm for the management of the distributed simulation. With the modeling method and the management algorithm we have the main elements for the practical implementation of the disperse productive system simulator
