Basic considerations of improving communication performances for parallel multi-processor system (PMPS) with optical interconnection network

Massively parallel processing is an important way to develop the high performance computer; and optical interconnection is of interest in the computer area. In this paper; the optoelectronic hybrid parallel multi-processor system (PMPS) developed in out laboratory is an attempt at using optical interconnection in order to solve the complex communication problem in the interconnection network of PMPS. Based on the model of communication sequential processes (CSP) a new architecture has been developed in which there are two multi-processor array layers; one of them is only for computation, the other for communication only between the processors in the first layer. The PMPS greatly improves the communication performances and releases the difficulties of system configuration by means of programs, and therefore the user could have a friendly interface.
