The approach described provides dynamic system-level load balancing in a topology independent fashion that is appropriate for avoiding gross imbalances of load. A number of novel techniques are combined with a heuristic to form a hybrid local garbage collector and load balancer. Multiple load measures are regularly compared, by each node with a dynamically varying subset of the others; and clumps of objects, selected to avoid breaking cycles, are transferred to improve the load balancing.</ABSTRACT></RECORD></RECORDS></XML>
