FIELD: computer networks. SUBSTANCE: system circuit has local processor center, remote processor center, and center-to-center interconnection circuit; each local processor center has local interconnection circuit, processor, system memory, and controller; mentioned controller discards data received from remote processor center in response to request provided response to this request received in local processor center is coherence pointing to modified or joint intervention. Method includes following operations: request received from local interconnection circuit is speculatively transferred to remote processor center and upon arrival of response to this request at local processor center mentioned response to request is processed in compliance with solution of this request in local processor center; with such processing of mentioned response to request data received from remote processor center are discarded in case response to this request received in local processor center is coherence pointing to modified or joint intervention. EFFECT: reduced time of data transfer operation execution. 10 cl, 4 dwg, 6 tbl
