Abstract
A partition establishment arrangement for use in a computer system comprising a plurality of processors interconnected by a communications network. The communications network comprises a plurality of communications nodes connected in a series of levels, with the nodes of at least some of the levels being controllable to connect to multiple ones of the nodes in a subsequent level. The partition establishment arrangement determines the controlling of the communication nodes to facilitate the partitioning of the processors into a plurality of partitions. The partition establishment arrangement, in a plurality of iterations, identifies conflict sets of processors to be assigned to respective partitions at a level, each conflict set identifying partitions for which, at a selected level, a processor may be connected to the same communications nodes in the next level. In each iteration, a level processing portion determines a control value for controlling the communications nodes in response to the conflict sets identified for the level. The operations continue through each of the successive levels.
