PROBLEM TO BE SOLVED: To obtain a high speed communication method using socket API or MPI API. SOLUTION: Five novel functions are used. (1) The receiving side informs the transmitting side of a data length for determining which of reception at application data 202 or reception at a previously assigned buffer 242 is optimal. (2) An effect of informing the reception address of the application data 202 is calculated and information is suppressed if the effect is low. (3) A communication protocol enabling eight communication methods is used. (4) A transfer data length expected for transmitting/receiving operation is informed previously to the opposite party. (5) Previously assigned buffers 142 and 242 are altered (extension, contraction, addition, deletion, and the like) according to a communication pattern. According to these functions, high speed communication is attained while reducing the overhead of processing and the amount of memory being used.
