<p><P>PROBLEM TO BE SOLVED: To provide a distributed shared memory control system capable of reducing delay in operation processing and data screen display processing for each node without causing shortages of a band for performing other inter-application communications on the same network and a storage capacity for storing the past data group. <P>SOLUTION: When storing a data group, an operation node 11 writes the data group into a shared memory 13 of the operation node 11, a storage device 15 of the operation node 11, and shared memories 13a to 13n of respective display nodes 12a to 12n. When referencing a data group, the display nodes 12a to 12n read the data group from a shared memory of their own node if the data group is stored in the shared memory of their own node, and read the data group from the storage device 15 of the operation node 11 if the data group is not stored in the shared memory of their own node. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
