Information processing system for performing mutual control of input/output devices among a plurality of clusters

摘要

In an information processing system including a first cluster which issues a control instruction for controlling an input/output device (14) of another cluster and a second cluster which executes processing by the input/output device according to the control instruction, which are connected through a network interconnecting clusters, a processor (11) mounted on the first cluster comprises a cluster discrimination unit (111) for discriminating a cluster which executes the control instruction and an instruction transfer unit (112) for transferring the control instruction to the corresponding second cluster depending on the judgment of the cluster discrimination unit, while a data transfer processing device (15) mounted on the second cluster comprises a transfer buffer (157) for temporarily storing the data to be transferred to another cluster, a transfer buffer control unit (158) for controlling reading and writing of the data from and into the transfer data storage unit, and a transfer control unit (154) for controlling the transfer buffer control unit according to the control instruction from the first cluster.
