Abstract
A Distributed Shared Memory (DSM) system that provides a single address space shared by a number of processes The DSM is capable of accomplishing lowered granularity of distributed shared memory. The DSM system includes the address space constituting a virtual address space that includes virtual pages. Two or more virtual pages in the virtual address space are mapped to the same memory page that includes one page. The page includes two or more minipages. There is further provided an assignor assigning independently, through the virtual pages, access permission to minipages that reside in the same page of the memory object. There is further provided processor processing independently in different processes minipages that reside in the same page.
