Information processing system and information processing method

An information processing method in an information processing system that includes one or more information processing apparatuses to process information, the method comprising:

• a division step of, by the information processing apparatus, dividing processing information into a plurality of pieces, under a division condition that designates parallel processing among the information processing apparatuses, the processing information indicating a data processing procedure from a plurality of start points to one or more end points;
• a determination step of, by the information processing apparatus, uniquely determining an assignee of each piece of the processing information divided by the division step, as any of the information processing apparatuses;
• an execution step of, by the information processing apparatus, executing a process in the information processing apparatus determined by the determination step;
• and
• a division position recommendation step of, by the information processing apparatus, calculating at least one item selected between CPU processing time periods of a plurality of processing parts and a data output amount, based on sample data that corresponds to the processing information, wherein
• the division position recommendation step includes extracting each of the transfer candidate parts belonging to the sample data, creating one or more combinations of one or more transfer candidate parts from the extracted transfer candidate parts, dividing the processing information into a plurality of areas, with respect to each combination of the transfer candidate parts, based on the transfer candidate part belonging to the combination of the transfer candidate parts, calculating a total value of the CPU processing time periods with respect to each area of the created combinations, selecting the combination of the transfer parts from among the combinations of the transfer candidate parts, based on at least one of the calculated total value of the CPU processing time periods and a data transfer amount by the transfer candidate parts, updating the processing information so as to adopt each transfer candidate part belonging to the selected combination of the transfer parts, as the transfer part that performs data transfer between the processing parts, and outputting the updated processing information to the division function, and
• upon receiving the updated processing information, the division step further includes dividing a range in which the updated processing information is recorded, into a plurality of areas, based on the transfer part, and dividing the transfer part into a plurality of divided transfer parts, and distributing the divided transfer parts to the respective areas.
