Abstract

A computer comprising a plurality of processing nodes, a control node and a request distribution network. Each processing node receives processing requests and generates in response processed data. The control node generates processing requests for transfer to selected ones of the processing nodes as identified by associated request address information, and receives processed data in response, the request address information identifying selected ones of the processing nodes to receive a processing request in parallel. The request distribution network distributes the processing requests to the processing nodes and returns processed data to the control node. The network includes a plurality of request distribution nodes connected in a plurality of levels to form a tree-structure, including an upper root level and a lower leaf level. Each request distribution node is connected to receive processing requests from, and to couple processed data to, a parent, the parent of the request distribution node of the root level comprising the control node, and each request distribution node being further connected to couple processing requests to and receive processed data from, selected children, the children of the request distribution nodes of the leaf level comprising the processing nodes. Each request distribution node, in response to request address information received from its parent, identifies selected ones of its children and thereafter couples further request address information which it receives and processing requests in parallel to its children.
