An apparatus for performing partition scheduling in a manycore environment. The apparatus may perform partition scheduling based on a priority and in this instance, may perform partition scheduling to minimize the number of idle cores. The apparatus may include a partition queue to manage a partition scheduling event; a partition scheduler including a core map to store hardware information of each of the plurality of cores; and a partition manager to perform partition scheduling with respect to the plurality of cores in response to the partition scheduling event, using the hardware information.
