Abstract: PROBLEM TO BE SOLVED: To provide a nonuniform memory access(NUMA) computer system having a short inter-node communication waiting duration by providing a buffer control logic or the like for extracting a specified communication transaction from a transaction buffer and processing it by a third processing node. SOLUTION: This NUMA computer system 8 is provided with the transaction buffer connected to a mutual connecting means. This transaction buffer stores a communication transaction which defines the processing node excepting for a third processing node 10c as the destination (target). Corresponding to the determination to process the specified communication transaction, which originally defines the other processing node as the destination, by the third processing node 10c, the buffer control logic connected to the transaction buffer extracts the specified communication transaction from the transaction buffer and the transaction is processed by the third processing node 10c.
