<p>A information processing apparatus having a processor is controlled to execute a procedure of reading from the memory attribute information indicating a usage frequency of a register used by a process to be executed as a next process by the processor when the processor switches a process currently being executed, saving a value of the register used by the next process to be executed by the processor to the memory when the usage frequency of the register indicated by the attribute information is larger than a certain frequency, reading from the memory owner information indicating a process using the register to be used by the next process when the usage frequency of the register indicated by the attribute information is larger than the certain frequency, and restoring a register value saved in the memory to the register when the owner information indicates a process other than the next process.
