Abstract
An information processing system includes Spine switches, Leaf switches coupled to the Spine switches in a form of a Latin square fat tree, and apparatuses each coupled to any one of the Leaf switches and including a processor. The processor performs, in a case where the processor is included in one of first apparatuses coupled to one of first Leaf switches, first collective communication with others of the first apparatuses on a route via a first Spine switch. The first Leaf switches correspond to at least a portion of points other than points at infinity of a finite projective plane corresponding to the Latin square fat tree. The processor performs second collective communication with others of the first apparatuses on a route via a second Spine switch at each phase of the first collective communication. The second Spine switch is different from the first Spine switch.
