An attribute group storage unit acquires and holds attribute groups set to respective data blocks. A scenario determination unit determines respective transfer systems of the respective blocks between a memory of the lowest hierarchy and a memory of another hierarchy based on those attribute groups and a configuration of an arithmetic unit which is the parallel processor, and controls the transfer of the respective data blocks according to the determined transfer systems, and the parallel arithmetic operation corresponding to the transfer. Each of the attribute groups is necessary to determine the transfer systems, and includes one or more attributes not depending on the configuration of the parallel processor. The attribute groups of the write blocks are set assuming that each of the write blocks has already been located in the memory of another hierarchy, and is transferred to the memory of the lowest hierarchy.
