As parallel implementation of complex applications is becoming popular, the need for a high performance interprocessor communication system becomes imminent, especially in loosely coupled distributed-memory multiprocessor networks. An important factor in the efficiency of these networks is the effectiveness of the message-passing system which manages the data exchanges among the processors of the network. This paper presents the modeling and performance evaluation of a new Message-Passing System (MPS) for distributed multiprocessor networks without shared-memory and where the processors or Processing Elements (PEs) are connected to each other by point-to-point communication links. For maximum performance, the MPS manages the communication and the synchronization between the different tasks of an application by means of three approaches. One is an asynchronous send/receive …
