Abstract:
Abstract. This paper deals with the minimization of inter-task and inter-processor communication costs in the context of one SQL query mapping onto a sharednothing architecture, as far as the parallel decisional query processing is concerned. After setting both the models of the application handled and the target multiprocessor architecture, a study aimed at minimizing both inter-processor transfer times depending on the interconnection network topology, and the impact of pipeline starting/closing (start-up) times, is mainly presented. 1
