摘要：A NUMA type multiprocessor including a shared memory dispersedly arrangedin a plurality of nodes, wherein each node includes a register for instructing a page for

initialization and a register for giving an instruction to invalidate the data on the caches ofother nodes for each page when an OS recovers the page. Means is disposed for

restricting line transfer from other nodes and invalidating the data on the caches of othernodes when write occurs to the page designated by the former for initialization, etc. Acommand for collectively invalidating the page to other nodes is generated for the pagedesignated by the latter. There are further disposed means for storing the state wherethe page is exclusive, in response to each page of the main memory inside the node, andmeans for setting the state of the corresponding page to the exclusive state when theexecution of the latter command is completed.
