An information processing apparatus transferring data between at least a plurality of processors through first and second routes running through first and second data transfer circuits, which retires the first and second routes so as to reduce the power consumption under the control of a system control device. The system provides a unit for measuring the amounts of data transfer on the first and second routes and measures the usage rates of the first and second routes. It monitors the measured usage rates by the system control device and, when the usage rates are below a predetermined value, controls the first or second data transfer circuit to make it retire the first or second route.
