<p>PROBLEM TO BE SOLVED: To provide an ordering control mechanism which improves throughput and can perform management of ordering. SOLUTION: This concerns a distributed common memory system with plural nodes connected and has central operation processing parts A and B, memories C and D, input/output control partsαandβ, and input/output devices 1, 2, 3 and 4. The input/output control partsαandβhave memory write buffers 11 and 21 which successively store memory write outputted by the input/output devices 1, 2, 3 and 4, an ordering management circuit 4 for deciding a processed party, and a node selection table 5 having comparison data to select which node of 0 or 1 the memory write is for.</p> |
