Distributed processing apparatus and operating method thereof

A distributed processing method of a distributed processing apparatus, the distributed processing method comprising:

• receiving pieces of data from each of a plurality of child nodes in a first tree structure;
• performing a reduction operation on the pieces of data received from the plurality of child nodes;
• and
• controlling a data flow of a result of the reduction operation within a first tree structure based on a target height corresponding to the reduction operation,
• wherein the first tree structure comprises:
• a plurality of tree nodes configured to connect a plurality of nodes belonging to each of a plurality of groups, in which a plurality of operation nodes of the distributed processing apparatus is grouped, in a second tree structure;
• and
• additional nodes configured to connect root nodes among the plurality of tree nodes in a third tree structure.

A non-transitory computer-readable storage medium storing instructions that, when executed by a processor, cause the processor to perform a method of a distributed processing apparatus comprising:

• receiving pieces of data from each of a plurality of child nodes in a first tree structure;
• performing a reduction operation on the pieces of data received from the plurality of child nodes;
• and
• controlling a data flow of a result of the reduction operation within a first tree structure based on a target height corresponding to the reduction operation,
• wherein the first tree structure comprises:
• a plurality of tree nodes configured to connect a plurality of nodes belonging to each of a plurality of groups, in which a plurality of operation nodes of the distributed processing apparatus is grouped, in a second tree structure;
• and
• additional nodes configured to connect root nodes among the plurality of tree nodes in a third tree structure.
