摘要: A mechanism for performing collective operations. In software executing on a parent processor in first book, number of other processors are determined same or different book the data processing system that is needed to execute operation, thereby establishing plurality comprising and processors. processor, logically arranged as nodes hierarchical structure. The operation transmitted based hardware results received from execution processors, final result generated results, output.
