Abstract
An information processing system includes leaf switches connected in a form of a Latin square fat tree, information processing apparatuses connected to any one of the leaf switches, respectively, and a management apparatus including a first processor. The first processor extracts one or more rows and one or more columns from a lattice portion other than an infinite original point of a finite projection plane corresponding to the Latin square fat tree. The first processor specifies leaf switches corresponding to points included in the extracted one or more rows and included in the extracted one or more columns. The first processor transmits an instruction to execute an all-reduce communication, in which a result of the communication is shared by all members that execute the communication, to a predetermined number of information processing apparatuses among the information processing apparatuses connected to the specified leaf switches.
