Abstract
In a shared memory type multiprocessing system, when data stored in each processing element is managed in a directory method, a plurality of processing elements are grouped in advance. A directory memory is provided along with a data memory mounted in a shared memory. Directory information held in the directory memory indicates which one of the groups holds a copy of a data block. In response to a request from the processing element, the shared memory executes a process of finding the processing element from the processing group, or a process of finding the processing group from the processing element.
