Abstract
To perform a cluster operation of a plurality of multi-function devices, if the number of devices in a stand-by state is smaller than a required number of devices, a device in a sleep state is restored to the stand-by state. In this case, a device that returns to the stand-by state earliest is selected and restored to the stand-by state.
Claims38
A control device for controlling a cluster operation of a plurality of devices, comprising:
- a restoring portion for restoring a device in an energy saving state to a stand-by state, if the number of devices in the stand-by state is smaller than a required number of devices for the cluster operation;
- and
- a distribution portion for distributing a job to each device, if a sum of the number of devices in the stand-by state and the number of devices restored to the stand-by state by said restoring portion reaches said required number.
A control device for controlling a cluster operation of a plurality of devices, comprising:
- a selecting portion for selecting an insufficient number of devices from among the devices in an energy saving state, if the number of devices in a stand-by state is less than a required number of devices for the cluster operation;
- and
- a distribution portion for distributing a job to each device already in the stand-by state and each device in the energy saving state that is selected by said selecting portion.
A control method for controlling a cluster operation of a plurality of devices, comprising:
- a restoring step of restoring a device in an energy saving state to a stand-by state, if the number of devices in the stand-by state is smaller than a required number of devices for the cluster operation;
- and
- a distribution step of distributing a job to each device, if the sum of the number of devices in the stand-by state and the number of devices restored to the stand-by state at said restoring step reaches said required number.
A control method for controlling a cluster operation of a plurality of devices, comprising:
- a selecting step of selecting an insufficient number of devices from among the devices in an energy saving state, if the number of devices in a stand-by state is less than a required number of devices for the cluster operation;
- and
- a distribution step of distributing a job to each device already in the stand-by state and each device in the energy saving state that is selected at said selecting step.
A computer program for controlling the cluster operation of a plurality of devices, which runs on a computer, comprising:
- a restoring step code for restoring a device in an energy saving state to a stand-by state, if the number of devices in the stand-by state is less than a required number of devices for the cluster operation;
- and
- a distribution step code for distributing a job to each device, if the sum of the number of devices in the stand-by state and the number of devices restored to the stand-by state at said restoring step reaches said required number.
A computer program for controlling the cluster operation of a plurality of devices, which runs on a computer, comprising:
- a selecting step code for selecting an insufficient number of devices from among the devices in an energy saving state, if the number of devices in a stand-by state is less than a required number of devices for the cluster operation;
- and
- a distribution step code for distributing a job to each device already in the stand-by state and each device in the energy saving state that is selected at said selecting step.
A network device in which a cluster operation can be realized in cooperation of a plurality of network devices, comprising:
- a determination portion for determining whether or not the cluster operation is running if the conditions for transferring to an energy saving state are met;
- and
- a state transfer portion for transferring to the energy saving state in accordance with an instruction from an external device, irrespective of said conditions, if it is determined that the cluster operation is running.
A control method for a network device in which the cluster operation can be realized in cooperation of a plurality of network devices, comprising:
- a determination step of determining whether or not the cluster operation is running if the conditions for transferring to an energy saving state are met;
- and
- a state transfer step of transferring to the energy saving state in accordance with an instruction from an external device, irrespective of said conditions, if it is determined that the cluster operation is running.
