Abstract

An information processing apparatus manages distributed processing by a plurality of devices which are connected to a computer network and have a power-saving mode. The apparatus includes a retriever, arranged to retrieve device information and operation states of the plurality of devices, and a selector, arranged to select target devices of the distributed processing based on at least one of the device information and operation states.

Claims

1. An information processing apparatus for managing distributed processing by a plurality of devices which are connected to a computer network and have a power-saving mode, comprising:

a retrieve section, configured to retrieve device information and an operation state of each device; and

a selection section, configured to select target devices of the distributed processing,

wherein, in a case where the device information retrieved from a device indicates that power consumption of the device in a normal operation of the device is equal to or less than a predetermined threshold, the selection section selects the device as the target device without determining the operation state of the device regarding the power-saving mode, and

wherein, in a case where the device information retrieved from a device indicates that power consumption of the device in a normal operation of the device is greater than the predetermined threshold, and the operation state retrieved from the device indicates that the device is in the power-saving mode, the selection section does not select the device as the target device.

2. The apparatus according to claim 1, wherein, in a case where the device information retrieved from a device indicates that power consumption of the device in a normal operation of the device is greater than the predetermined threshold, and the operation state retrieved from the device indicates that the device is not in the power-saving mode, the selection section determines whether or not the device is selected as the target device in accordance with unused time information required until the device will shift to the power-saving mode and current unused time information of the device indicated by the device information.

3. The apparatus according to claim 1, further comprising a notification section configured to notify information indicating the target devices selected by the selection section to a request source of the distributed processing.

4. A method of controlling an information processing apparatus for managing distributed processing by a plurality of devices which are connected to a computer network and have a power-saving mode, the method comprising:

using a processor to perform the steps of;

retrieving device information and an operation state of each device; and

selecting target devices of the distributed processing,

wherein in the selecting step, in a case where the device information retrieved from a device indicates that power consumption of the device in a normal operation of the device is equal to or less than a predetermined threshold, the device is selected as the target device without determining the operation state of the device regarding the power-saving mode, and

wherein in the selecting step, in a case where the device information retrieved from a device indicates that power consumption of the device in a normal operation of the device is greater than the predetermined threshold, and the operation state retrieved from the device indicates that the device is in the power-saving mode, the device is not selected as the target device.

5. The method according to claim 4, wherein in the selecting step, in a case where the device information retrieved from a device indicates that power consumption of the device in a normal operation of the device is greater than the predetermined threshold, and the operation state retrieved from the device indicates that the device is not in the power-saving mode, it is determined whether or not the device is selected as the target device in accordance with unused time information required until the device will shift to the power-saving mode and current unused time information of the device indicated by the device information.

6. The method according to claim 4, further comprising the step of notifying information which indicates the target devices selected in the selecting step to a request source of the distributed processing.

7. A non-transitory computer-readable medium storing a computer-executable program for causing a computer to perform a method of controlling an information processing apparatus for managing distributed processing by a plurality of devices which are connected to a computer network and have a power-saving mode, the method comprising the steps of:

retrieving device information and an operation state of each device; and

selecting target devices of the distributed processing,

wherein in the selecting step, in a case where the device information retrieved from a device indicates that power consumption of the device in a normal operation of the device is equal to or less than a predetermined threshold, the device is selected as the target device without determining the operation state of the device regarding the power-saving mode, and

wherein in the selecting step, in a case where the device information retrieved from a device indicates that power consumption of the device in a normal operation of the device is greater than the predetermined threshold, and the operation state retrieved from the device indicates that the device is in the power-saving mode, the device is not selected as the target device.
