摘要: A collective communication apparatus and method for parallel computing systems. For example, one embodiment of an comprises a plurality processor elements (PEs); interconnect logic to dynamically form virtual (VCI) between the PEs at runtime without global among all PEs, VCI defining logical topology in which each PE is directly communicatively coupled only subset remaining PEs; execution execute operations across wherein or more receive first results from portion perform operations, provide second PEs.
