GENERATIVE COORDINATION ENVIRONMENTS SUPPORTING PARALLEL DISCRETE-EVENT SIMULATION

The utilization of coordination languages based on the generative para digm for supporting the implementation of parallel discrete-event simu lators is considered. A parallel simulation methodology called Active- Events (ActE) which is based on a sophisticated generative coordinatio n model is proposed in order to make the task of designing a parallel simulator easier and to fully exploit the capabilities of coordination languages. An implementation of mechanisms of the coordination model by relying on the Linda coordination language is proposed. A simulator for queuing models based on ActE and developed in the coordination fr amework thus resulting is experimentally studied to assess the suitabi lity of different mechanisms which implement the particular object ret rieval criterion of the coordination model.
