Abstract
An information processing apparatus according to an embodiment includes a first memory, a non-volatile memory, and one or more processors. The processor is configured to execute information processing on data stored in those memories. The processor allocates, to each of pages included in a file stored in the non-volatile memory by executing an operating system, a memory access method that indicates either copy access processing or direct access processing to be executed. The copy access processing performs writing and readout of data copied from the non-volatile memory into the first memory. The direct access processing directly performs writing and readout of data stored in the non-volatile memory. The processor accesses those memories by the memory access method allocated to each of the pages included in the file when the operating system receives a request from an application program for writing or readout on the file.
