Abstract

An information processing system includes: a plurality of information processing devices; a plurality of power storage devices configured to supply DC power to any of the plurality of information processing devices; a plurality power source devices configured to supply DC power to the plurality of power storage devices; and an arithmetic unit configured to, in accordance with the charged state of any of the plurality of power storage devices and a task to be processed by the information processing device to which DC power is supplied from the power storage device, allocating the task to be processed by the information processing device to an information processing device to which DC power is not supplied from the power storage device.

First claim

What is claimed is:

1. An information processing system comprising:
a plurality of information processing devices;
a plurality of power storage devices configured to supply DC power to any of the plurality of information processing devices;
a plurality of power source devices configured to supply DC power to the plurality of power storage devices; and
an arithmetic unit configured to, in accordance with the charged state of any of the plurality of power storage devices and an amount of a task to be processed by the information processing device to which DC power is supplied from the power storage device, allocate the task to be processed by the information processing device to an information processing device to which DC power is not supplied from the power storage device, wherein
the power source device includes a power consumption monitoring unit configured to monitor power consumption of the corresponding information processing device,
the power storage device includes a charge power control unit configured to control the storage of DC power from the power source device and a charged capacity monitoring unit configured to monitor the charged capacity, and
the arithmetic unit collects the power consumption of the information processing device detected by the power consumption monitoring unit and the charged capacity detected by the charged capacity monitoring unit.

2. An information processing system comprising:
a plurality of information processing devices;
a plurality of power storage devices configured to supply DC power to any of the plurality of information processing devices;
a plurality of power source devices configured to supply DC power to the plurality of power storage devices; and
an arithmetic unit configured to, in accordance with the charged state of any of the plurality of power storage devices and an amount of a task to be processed by the information processing device to which DC power is supplied from the power storage device, allocate the task to be processed by the information processing device to an information processing device to which DC power is not supplied from the power storage device, wherein
the arithmetic unit allocates an amount of the task to the information processing device corresponding to the power storage device the charged state of which is lower than that of the other power storage devices less than the amount of the task of the other information processing devices.

3. An information processing system comprising:
a plurality of information processing devices configured to distribute and process a task;
a plurality of power source devices provided in correspondence to the plurality of information processing devices and configured to supply DC power to the corresponding information processing device;
a plurality of power storage devices provided in correspondence to the plurality of information processing devices and configured to back up DC power from the corresponding power source device; and
an arithmetic unit configured to allocate the task to the plurality of information processing devices in accordance with the charged state of the plurality of power storage devices, wherein
the power source device includes a power consumption monitoring unit configured to monitor power consumption of the corresponding information processing device,
the power storage device includes a charge power control unit configured to control the storage of DC power from the power source device and a charged capacity monitoring unit configured to monitor the charged capacity, and
the arithmetic unit collects the power consumption of the information processing device detected by the power consumption monitoring unit and the charged capacity detected by the charged capacity monitoring unit.

4. An information processing system comprising:
a plurality of information processing devices configured to distribute and process a task;
a plurality of power source devices provided in correspondence to the plurality of information processing devices and configured to supply DC power to the corresponding information processing device;
a plurality of power storage devices provided in correspondence to the plurality of information processing devices and configured to back up DC power from the corresponding power source device; and
an arithmetic unit configured to allocate the task to the plurality of information processing devices in accordance with the charged state of the plurality of power storage devices, wherein
the arithmetic unit allocates an amount of the task to the information processing device corresponding to the power storage device the charged state of which is lower than that of the other power storage devices less than the amount of the task of the other information processing devices.

5. An uninterruptible power system comprising:
a plurality of power source devices provided in correspondence to a plurality of pieces of DC equipment configured to perform processing in collaboration with one another and configured to supply DC power to the corresponding DC equipment;
a plurality of power storage devices provided in correspondence to the plurality of pieces of DC equipment and configured to back up DC power from the corresponding power source device; and
a control unit configured to allocate the processing to the plurality of pieces of DC equipment in accordance with the charged state of the plurality of power storage devices, wherein
the power source device includes a power consumption monitoring unit configured to monitor power consumption of the corresponding DC equipment,
the power storage device includes a charge power control unit configured to control the storage of DC power from the power source device and a charged capacity monitoring unit configured to monitor the charged capacity, and
the control unit collects the power consumption of the DC equipment detected by the power consumption monitoring unit and the charged capacity detected by the charged capacity monitoring unit.

6. An uninterruptible power system comprising:
a plurality of power source devices provided in correspondence to a plurality of pieces of DC equipment configured to perform processing in collaboration with one another and configured to supply DC power to the corresponding DC equipment;
a plurality of power storage devices provided in correspondence to the plurality of pieces of DC equipment and configured to back up DC power from the corresponding power source device; and
a control unit configured to allocate the processing to the plurality of pieces of DC equipment in accordance with the charged state of the plurality of power storage devices, wherein
the control unit allocates an amount of the processing to the DC equipment corresponding to the power storage device the charged state of which is lower than that of the other power storage devices less than the amount of the processing of the other pieces of DC equipment.
