Title: INFORMATION PROCESSING DEVICE, INFORMATION PROCESSING METHOD, AND PROGRAM
Abstract:
[Problem] To avoid route competition when carrying out an all-reduce communication in a multilayer full mesh system. [Solution] Provided is a first information processing device, comprising: a first communication unit for carrying out a first all-reduce communication with other information processing devices connected to a first leaf switch which the first information processing device is connected to; a second communication unit for carrying out, using the result of the first all-reduce communication, a second all-reduce communication with a single information processing device which is connected to a second leaf switch included in the same layer as the first leaf switch, and a third all-reduce communication with a single information processing device connected to a third leaf switch which is connected to a spine switch connected to the first leaf switch and which is included in a different layer from the layer wherein the first leaf switch is included; and a third communication unit which transmits the result of the process performed by the second communication unit to the other information processing devices connected to the first leaf switch.
