Power Saving Method for Computer System
First Claim
1. A server computer system including a central processing unit (CPU) operable at a plurality of levels of power, the server computer system providing a service that follows a predetermined protocol identified by a port number to a client computer via a computer network, the server computer system comprising:
- a communication monitoring unit for monitoring a status of communication with the client computer and retaining a communication status data table that contains a connection ID and a port number for the communication;
a power level determining unit for determining a power level to be set as a power level of the CPU on the basis of data in the communication status data table; and
a power level setting unit for setting the power level of the CPU to the determined power level.

Abstract
A server system, method, and program product are provided for setting a power level of a central processing unit (CPU) included in the server computer system—the CPU being operable at a plurality of levels of power, and the server providing a service that follows a predetermined protocol identified by a port number to a client computer via a computer network. The method includes the steps of monitoring connection establishment or close of communication with the client computer and a port number for the established or closed communication, determining a power level to be set as the power level of the CPU in accordance with the port number, and setting the determined power level as the power level of the CPU.
