This job allocation method for allocating jobs to each computer that processes the job without intensively managing a load state of each computer includes: identifying computers having a configuration necessary for a processing of a generated job by using a profile management data storage storing data of a configuration of each computer; identifying a job allocation mode according to a current job generation state by using an allocation mode data storage storing data concerning an allocation mode of computers to the jobs in association with the job generation state; transmitting a job generation notification to at least one of the identified computers according to the identified job allocation mode; and when a job acquisition refusal notification is received in response to the job generation notification, resending a job generation notification to a computer having a configuration necessary for the generated job. Thus, by sending the job generation notification, not a job allocation notification, without intensively managing the load state of each computer, which processes the jobs, it is possible to reduce the processing load of a master computer.
