<p>PURPOSE:To attain synchronous control and consistency guaranteed control by the small number of network packets and to improve access performance to a distributed shared memory in a distributed shared memory system in a loosely coupled computer system. CONSTITUTION:A main memory 106 is provided with a consistency guaranteed control specifying instruction string memory 201, a shared data memory 203, a shared data consistency guaranteed control instruction string memory 204, a shared data management table 206, a priority queue 205 with a shared data queuing counter, and so on. When an instruction string in the memory 201 is executed or a packet is received from another computer, an instruction string in the memory 204 is executed. When the instruction string in the memory 204 refers to and changes table 206 and the queue 205, the consistency of the memory 203 and the synchronism of parallel programs can be controlled.</p> |
