Broadcast transfer method for a hierarchical interconnection network with multiple tags

摘要

A broadcast transfer method for transferring the same data from any one node of the interconnection network of the parallel processing computer to every other nodes. The object of the present invention is to provide a broadcast transfer method for a hierarchical interconnection network with multiple tags which can be easily expanded, wherein each switch can perform a routing control function, and which enables the same packet to be transferred irrespective of the receiving group of each layer even when multiple tags are used in the same manner as in the point-to-point packet transfer. The broadcast transfer method for a hierarchical interconnection network with multiple tags in accordance with the present invention comprises the steps of using a single tag structure; discriminating if a routing switch belongs to a layer one cluster interconnection network or a layer two cluster interconnection network by using a hub/cluster discrimination signal; and outputting the corresponding packet type in accordance with the input location where a packet is received at the corresponding routing switch to enable all receiving nodes to receive the same data.
