    Abstract: Disclosed are a method of and a system for synchronizing clocks in a coordinated network of computers including a multitude of processing nodes, each of the nodes having a clock and one or more neighbor nodes. The method comprises the steps of electing one of the nodes as a correct leader node; and each of the non-leader nodes adjusting its clock rate, based on messages exchanged with neighbor nodes, to remain synchronized with the clock of said correct leader node. In a preferred embodiment, the adjusting step includes the step of each of the non-correct leader nodes using a weight assignment mechanism that gives neighbor nodes that are closer to the leader node more effect on the clock adjustment than those nodes that are further away from the correct leader node.
