PROBLEM TO BE SOLVED: To reduce device start-up time of a computer, to improve utilization efficiency of the computer.SOLUTION: At least one of a plurality of arithmetic processing units executes initial processing, including at least one of initialization and diagnosis processing, to a first area of a main storage unit to be used for loading an operating system from an input-output unit. After the initial processing on the first area, one of the arithmetic processing units loads the operating system to the first area from the input-output unit. The other arithmetic processing unit starts initial processing for an unprocessed area of the main storage unit while the one arithmetic processing unit is in process. After the loading, the one arithmetic processing unit starts booting the operating system.SELECTED DRAWING: Figure 3 |
