A full bisection bandwidth network, having a plurality of nodes and a plurality of paths among the nodes, is divided into a plurality of Virtual Local Area Networks ('VLANs') by assigning paths to the VLANs such that each VLAN satisfies a spanning tree protocol and all paths are active in at least one VLAN.

A 'group work sorting' technique is used in a parallel computing system that executes multiple items of work across multiple parallel processing units, where each parallel processing unit processes one or more of the work items according to their positions in a prioritized work queue that corresponds to the parallel processing unit. When implementing the technique, one or more of the parallel processing units receives a new work item to be placed into a first work queue that corresponds to the parallel processing unit and receives data that indicates where one or more other parallel processing units would prefer to place the new work item in the prioritized work queues that correspond to the other parallel processing units. The parallel processing unit uses the received data as a guide in placing the new work item into the first work queue.
