Abstract
Disclosed is a computer system containing plural processors, a shared storage shared by the plural processors, a buffer storage for storing a copy of a portion of data of the shared storage disposed in each of the plural processors, and a storage controller having a communication buffer storage disposed halfway between the buffer storage and the shared storage for storing a copy of a portion of data of the shared storage as an object for storing only an operand data of a particular instruction. This computer system can implement communication of data of the shared storage between the plural processors by using the communication buffer storage in an efficient way.
