• Recently, the optimization of the power consumption has become one of the crucial factors to design PC clusters. In this paper, we propose an on/off link regulation method that dynamically deactivates and reactivates the links for power regulations with maintaining the performance in InfiniBand which is a typical system area network used in PC clusters. The proposed method only requires the use of the APM (Automatic Path Migration) and the SMA (Subnet Manager Agent) for monitoring the traffic load. Thus, no modification is required on the hardware of switches, host-channel adapters, nor drivers. Since the available network resources (switch and links) are changed by link activation, the path set is updated by modifying forwarding tables of InfiniBand switches. Evaluation results show that the proposed method reduces the power consumption of InfiniBand by 13% with no performance degradation.
