PROBLEM TO BE SOLVED: To provide a device and a method improved in data processing efficiency by an improved context storage structure. SOLUTION: In a structure for executing data processing while relating a plurality of logical processors to a physical processor by time sharing, processing for mapping and storing a logical processor-corresponding context table laid in a non-applied state of the physical processor to a logical partition address space corresponding to a logical partition as the application object of the logical processors is executed. According to this structure, the context of the logical processors can be acquired in a state where the logical processors are not allocated to the physical processor, and processing such as access and program load can be executed to the logical processors without waiting for a physical processor allocation timing, and the data processing efficiency is improved.
