....computers is the interconnection network that connects all the processing elements together. A system containing many high speed processors places a great burden on the interconnection network. Such a network must have a high degree of connectivity, a small diameter, and a high bisection bandwidth. [19][20] Traditionally, the crossbar switch has been the ultimate goal in high speed networks. A crossbar switch is a fully connected network that contains a connection from each processor to every other processor. The diameter of a crossbar switch is always one since each processor is directly ....

....into this category. Such systems with direct interconnections are being used for supporting either distributed memory or distributed shared memory programming paradigms. In order to support these paradigms, the systems need fast communication and synchronization support from the underlying network [16]. The Message Passing Standard [18] has recently defined the importance of collective communication [17] One important category in this class is global reduction (sum, max, min, or user defined functions) where there is involvement from all processes of an user defined group. As defined by the ....
