PROBLEM TO BE SOLVED: To flexibly re-divide a graph according to change following the time of the weight of a new node and the weight of a new edge after the graphic is divided. SOLUTION: After the lapse of a certain time since the division processing of a graph, a threshold managing part 35 makes a load managing part 34 calculate the weight of a new node and the weight of a new edge based on a current parameter. When at least one of the weight of the new node and the weight of the new edge exceeds a threshold, a graph re-division instructing part 36 makes a graph division processing part 33 execute the division processing of the graph again.
