In a computing 
system where multiple servers are connected through a network and one or more jobs are run, a power reduction facility of a supervisory 
server relocates jobs according to predetermined conditions, thereby reducing the amount of power consumed by the computing 
system. For relocating the jobs, the power reduction facility obtains 
server-related information such as the power properties of the servers constituting the computing 
system and job-related information such as performance requirements for the jobs which are run in the computing system, and searches for one or more jobs to be relocated and destination servers, based on these 
server-related information and job-related information, to the extent that the performance requirements for each job are fulfilled. Based on the search results, the jobs are relocated to the destination servers, and servers on which no job is running, in consequence of the 
relocation, are powered off.
