摘要
“Per memory” atomic access for a distributed memory multiprocessor architecture is provided by marking bit masks for shared memories to indicate the access privileges of processors to the memories. A processor has access privileges to a shared memory if the bit mask retained for the memory is marked at a bit position reserved for the processor and does not have access privileges if the bit mask is not so marked. A bit mask is permitted to have only one mark at a given time to guarantee that access to each shared memory is atomic.
