Abstract
Systems and methods for reducing power consumption during data transport across multiple processors when link utilization is low. In a multi-node system, at least one of two nodes may indicate low utilization for a given link between them. In response to further determining no enabled link between the two nodes is over utilized, each of the two nodes may remove the given link from consideration for being scheduled to receive data for transfer and turn off the given link when no more transactions are scheduled for the given link. Disabled links may be re-enabled when high utilization is detected on at least one link between the two nodes.
