39 Parallel Transaction-oriented Simulation simulation systems are best suited for the simulation of systems that contain relatively independent sub-systems. In practice the ratio of computation performance to communication performance provided by the underlying hardware architecture of the Grid environment will have to match the ratio of computation performance to communication performance required by the parallel simulation as reasoned in 2.2. Whether a partitioned simulation model will perform well will therefore also depend on the underlying hardware architecture.
5 Implementation 40 Implementation The GPSS based parallel transaction-oriented simulator will be implemented using the Java TM 2 Platform Standard Edition 5.0, also known as J2SE5.0 [31] and ProActive version <strong>3.1</strong> [15] as the Grid environment. An object-oriented design will be applied for the implementation of the simulator and resulting classes will be grouped into a hierarchy of packages according to the functional parts of the parallel simulator and the implementation phases. The parallel simulator will use the logging library log4j [3] for all its output, which will provide very flexible means to enable or disable specific parts of the output as required. The log4j library is the same logging library that is used by ProActive so that only one configuration file will be needed to configure the logging of ProActive and the parallel simulator. 5.1 Implementation Considerations 5.1.1 Overall Architecture Figure 11 shows the suggested architecture of the parallel simulator including its main components. The main parts of the parallel simulator will be the Simulation Controller and the Logical Processes. The Simulation Controller controls the overall simulation. It is created when the user starts the simulation and will use the Model Parser component to read the simulation model file and parse it into an in memory object structure representation of the model. After the model is parsed the Simulation Controller will create Logical Process instances, one for each model partition contained within the simulation model. The Simulation Controller and the Logical Processes will be implemented as ProActive Active Objects so that they can communicate with each other via method calls. Communication will take place between the Simulation Controller and the Logical Processes but also between the Logical Processes for instance in order to exchange Transactions. Note that the communication between the Logical Processes is not illustrated in Figure 11. After the Logical Process instances have been created, they will be initialised, they will receive the model partitions from the Simulation Controller that they are going to simulate and the simulation is started.
