Abstract

PROBLEM TO BE SOLVED: To control a power consumed in a control target device while placing priority to a reduction in consumption power of the entire control target device.SOLUTION: An information processing apparatus includes: temperature acquisition means for acquiring, when a first processing apparatus completes processing allocated thereto, temperatures corresponding to the first processing apparatus and a second processing apparatus in a standby mode, respectively; and processing allocation means for comparing between the acquired temperatures and allocating new processing to any one of the first and second processing apparatuses with the lower temperature.

Description

  The present invention relates to a technology for controlling power consumption, and more particularly to a technology for controlling power consumption of a controlled device based on the temperature of the controlled device.

  A technique for controlling the power consumption of a controlled apparatus based on the temperature of the controlled apparatus and various related techniques are known.

  For example, Patent Document 1 discloses an example of a method for controlling power in a multi-core central processing unit. The method described in Patent Document 1 includes the following steps. The first step monitors the die temperature of each core in the multi-core central processing unit, and the second step determines the degree of workload parallelism in the multi-core central processing unit. The third step turns on or off the power of each of the cores based on the die temperature and the determination result.

  Patent Document 2 discloses a technique for suppressing a decrease in performance while performing control so that the temperature of a hot spot does not exceed an allowable value in an information processing apparatus including a plurality of processors. The information processing apparatus described in Patent Literature 2 has the following configuration. The temperature sensor measures the temperature of each processor. The interrupt reception unit receives an interrupt. The processor selection unit selects the processor having the lowest measured temperature. The interrupt output unit requests the accepted interrupt from the selected processor.

  However, the technique described in the above-described prior art document has a problem in that it is not possible to control the power of the controlled target device in preference to reducing the power consumption of the entire controlled target device.

  The reason is as follows.

  The method described in U.S. Pat. No. 6,057,051 is based on whether there is sustained parallelism in the multi-core central processing unit when the die temperature reaches a threshold and there is a dormant core. The sleeping core is turned on or off. Therefore, priority is not given to reducing the power consumption of the entire multi-core central processing unit.

  Further, the information processing apparatus described in Patent Document 2 only determines which processor is requested to receive the accepted interrupt based on the temperature of those processors. Therefore, the power consumption of the entire information processing apparatus is not reduced.

  An object of the present invention is to provide an information processing apparatus, a power control method, and a program therefor that solve the above-described problems.

  The information processing apparatus according to the present invention acquires a temperature corresponding to each of the first processing apparatus and the second processing apparatus in standby when the first processing apparatus completes the assigned process. An acquisition unit and a process allocation unit that compares the acquired temperature and allocates a new process to one of the first and second processing devices having the lowest temperature.

According to the power control method of the present invention, when the computer completes the process to which the first processing apparatus is assigned, the temperature corresponding to each of the first processing apparatus and the second processing apparatus in standby is set. Acquire, compare the acquired temperatures, and assign a new process to one of the first and second processing apparatuses having the lowest temperature.
The program of the present invention acquires the temperature corresponding to each of the first processing device and the waiting second processing device when the first processing device completes the assigned process, and the acquisition Then, the computer is caused to execute a process of assigning a new process to one of the first and second processing apparatuses having the lowest temperature.

  The present invention has an effect that it is possible to control the power of the controlled target device by giving priority to the reduction of the power consumption of the entire controlled target device.

  This completes the description of each component of the functional unit of the power control apparatus 100.

  Next, components in hardware units of the power control apparatus 100 will be described.

  FIG. 3 is a diagram illustrating a hardware configuration of a computer 700 that implements the power control apparatus 100 according to the present embodiment.

Furthermore, the computer 700 includes a recording medium (or storage medium) 707 supplied from the outside. For example, the recording medium 707 is a non-volatile recording medium (non-temporary recording medium) that stores information non-temporarily. The recording medium 707 may be a temporary recording medium that holds information as a signal.

  The CPU 701 controls the overall operation of the computer 700 by operating an operating system (not shown). The CPU 701 reads a program and data from a recording medium 707 mounted on the storage device 703, for example, and writes the read program and data to the storage unit 702. Here, the program is, for example, a program that causes the computer 700 to execute an operation of a flowchart shown in FIG.

  The CPU 701 executes various processes as the temperature acquisition unit 110 and the process allocation unit 120 illustrated in FIG. 1 according to the read program and based on the read data.

  Note that the CPU 701 may download a program and data to the storage unit 702 from an external computer (not shown) connected to a communication network (not shown).

  The storage unit 702 stores programs and data. The storage unit 702 stores, for example, control information 180 shown in FIG.

  The storage device 703 is, for example, an optical disk, a flexible disk, a magnetic optical disk, an external hard disk, and a semiconductor memory, and includes a recording medium 707. The storage device 703 (recording medium 707) stores the program in a computer-readable manner. Further, the storage device 703 may store, for example, control information 180 shown in FIG.

  The input unit 704 is realized by, for example, a mouse, a keyboard, a built-in key button, and the like, and is used for input operations. The input unit 704 is not limited to a mouse, a keyboard, and a built-in key button, and may be a touch panel, for example. For example, the input unit 704 receives setting information for the power control apparatus 100 by the operator. For example, the setting information is an identifier of a server that is a target of power control by the power control apparatus 100.

  The output unit 705 is realized by a display, for example, and is used for confirming the output. For example, the output causes the operator to confirm the setting information described above.

  The communication unit 706 implements an interface with the servers 411 to 414, the temperature sensor 111, and the temperature sensor 112. It is included as part of the temperature acquisition unit 110 and the processing allocation unit 120.

  As described above, the functional unit block of the power control apparatus 100 shown in FIG. 1 is realized by the computer 700 having the hardware configuration shown in FIG. However, the means for realizing each unit included in the computer 700 is not limited to the above. In other words, the computer 700 may be realized by one physically coupled device, or may be realized by two or more physically separated devices connected by wire or wirelessly and by a plurality of these devices. .

  A recording medium 707 in which the above-described program code is recorded may be supplied to the computer 700, and the CPU 701 may read and execute the program code stored in the recording medium 707. Alternatively, the CPU 701 may store the code of the program stored in the recording medium 707 in the storage unit 702, the storage device 703, or both. That is, the present embodiment includes an embodiment of a recording medium 707 that stores a program (software) executed by the computer 700 (CPU 701) temporarily or non-temporarily. A storage medium that stores information non-temporarily is also referred to as a non-volatile storage medium.

  The above is the description of each component in hardware units of the computer 700 that implements the power control apparatus 100 according to the present embodiment.

  The power control apparatus 100 may include the computer 700, the temperature sensor 111, and the temperature sensor 112 as components in hardware units.

  Next, the operation of the present embodiment will be described in detail with reference to FIGS.

  FIG. 4 is a diagram illustrating an example of the control information 180 in the present embodiment. As shown in FIG. 4, the control information 180 includes a server identifier, a state, and a temperature.

  The server identifiers “SV11” to “SV41” shown in FIG. 4 are the identifiers of the servers 411 to 414 shown in FIG.

  The “operation”, “complete”, and “standby” in the state illustrated in FIG. 4 indicate that the servers 411 to 414 are executing the process t, completing the process t, and waiting. Show. In other words, the control information 180 illustrated in FIG. 4 indicates that the server 412 is a completion server and the server 413 is a standby server.

  Moreover, each numerical value of the temperature shown in FIG. 4 is the temperature acquired by the temperature acquisition unit 110.

  FIG. 5 is a flowchart showing the operation of the present embodiment. Note that the processing according to this flowchart may be executed based on the program control by the CPU 701 described above. Further, the step name of the process is described by a symbol as in S601.

  The power control apparatus 100 waits for the process t to end in any of the servers 411 to 414 (S601).

  When the process t ends in any of the servers 411 to 414 (YES in S601), the process proceeds to S602. Here, for example, it is assumed that the process t ends in the server 412. At this time, for example, as illustrated in FIG. 4, the power control apparatus 100 may rewrite the state corresponding to the server 412 from “operation” to “completed”.

  Next, the temperature acquisition unit 110 acquires the temperatures of the completion server (the server 412 in the case of the control information 180 shown in FIG. 4) and the standby server (the server 413 in the case of the control information 180 shown in FIG. 4) (S602). ).

  For example, the temperature acquisition unit 110 may record the acquired temperature in the control information 180 illustrated in FIG. For example, “93” of the temperature corresponding to the identifier “SV12” shown in FIG. 4 and “50” of the temperature corresponding to “SV13” are the temperatures (Celsius) acquired in S602.

  Next, the process allocation unit 120 compares the acquired temperatures and detects the lowest temperature. Subsequently, the process allocation unit 120 allocates a new process t to the server 413 identified by the identifier “SV13” corresponding to the lowest temperature “50” (S603). For example, the process allocation unit 120 may overwrite the state with the identifier “SV12” with “standby” and overwrite the state with the identifier “SV13” with “operation”.

  Next, the process returns to S601.

  The above is the description of the operation of the present embodiment.

  In the above description, the case where any one of the servers 411 to 414 is set to the standby state has been described, but a plurality of the servers 411 to 414 are set to the standby state in accordance with the required power consumption reduction amount. As good as Similarly in this case, the temperature acquisition unit 110 acquires the temperatures of the completion server and the plurality of standby servers. Then, the process assignment unit 120 assigns a new process t to the servers 411 to 414 corresponding to the lowest temperature among the acquired temperatures.

  The first effect of the present embodiment described above is that it is possible to control the power of the controlled target device with priority on reducing the power consumption of the entire controlled target device.

  The reason is that the temperature acquisition unit 110 acquires the temperatures of the completion server and the standby server, and the process allocation unit 120 allocates a new process t to the server having the lowest acquired temperature.

  The second effect of the present embodiment described above is that the heat generation points can be dispersed in the entire controlled target device.

  The reason is the same as the reason for the first effect.

  The 3rd effect in this embodiment mentioned above is a point which makes it possible to change the reduction amount of the power consumption of the whole controlled object apparatus.

  The reason is that the temperature acquisition unit 110 acquires the temperatures of the completion server and the plurality of standby servers, and the process allocation unit 120 adds new information to the servers 411 to 414 corresponding to the lowest temperature among the acquired temperatures. This is because the process t is assigned.

<<< Second Embodiment >>>
Next, a second embodiment of the present invention will be described in detail with reference to the drawings. Hereinafter, the description overlapping with the above description is omitted as long as the description of the present embodiment is not obscured.

  FIG. 6 is a block diagram showing the configuration of the information processing apparatus 420 according to the second embodiment of the present invention. As illustrated in FIG. 6, the information processing apparatus 420 includes management software 421, a process 423, an OS (Operating System) 424, a logical processor 425, a hypervisor 426, a physical processor 427, and a temperature sensor 428.

  The information processing apparatus 420 has a general software structure in a virtual multiprocessor. Specifically, “OS # A”, “OS # B”, and “OS # C” of the OS 424 are movable on “LP # A0 to LP # C1” of a virtual processor called a logical processor 425. “Pa0 to Pan”, “Pb0 to Pbn”, and “Pc0 to Pcn” of the process 423 are executed on “OS # A”, “OS # B”, and “OS # C”, respectively. “LP # A0 to LP # C1” of the logical processor 425 are transferred to the “pp # 0”, “pp # 1”, “pp # 2”, and “pp # 2” of the physical processor 427 by the virtualization layer software called the hypervisor 426. assigned to pp # 3 "in a time-sharing manner. In other words, each of “pp # 0”, “pp # 1”, “pp # 2”, and “pp # 3” of the physical processor 427 is assigned the process 423 in a time division manner. The process 423 executed by the logical processor 425 is also called processing. Hereinafter, the process defined here is referred to as process p.

  Further, the management software 421 manages the operation of the entire information processing apparatus 420 via the hypervisor 426.

  Next, the operation of the information processing apparatus 420 will be described.

  When the management software 421 determines that power consumption reduction is necessary, the management software 421 transmits a power consumption reduction instruction to the hypervisor 426.

  The hypervisor 426 performs the same operation as that shown in FIG. 5 and performs processing in any one of “pp # 0”, “pp # 1”, “pp # 2”, and “pp # 3” of the physical processor 427. When p is completed, a new process p is assigned to one of the physical processors 427 having the lowest temperature among the completed processor and the standby processor. Here, the completion processor is a physical processor 427 that completes the assigned process p. The standby processor is the physical processor 427 in the standby state.

  That is, the hypervisor 426 includes the power control apparatus 100 shown in FIG.

  FIG. 7 is a diagram illustrating an example of assignment of the process p to the physical processor 427 in the present embodiment. In FIG. 7, the assigned process p is indicated by “LP # A0 to LP # C1” of the logical processor 425, and the description of the process 423 operating on the logical processor 425 is omitted.

  As shown in FIG. 7, at time t0, “pp # 3” of the physical processor 427 is in a standby state.

  For example, at time t1, the process p of “LP # A1” of the logical processor 425 ends with “pp # 1” of the physical processor 427.

  In this case, the hypervisor 426 acquires the temperatures of “pp # 1” of the completion processor and “pp # 3” of the standby processor.

  Next, the hypervisor 426 adds a new process p (process of “LP # C0” of the logical processor 425) to the physical processor 427 having a lower temperature (here, “pp # 3” in the standby state). Assign. As a result, “pp # 3” of the physical processor 427 enters an operating state. On the other hand, “pp # 1” of the physical processor 427 enters a standby state.

  Further, at time t5, the process p of “LP # A1” of the logical processor 425 ends at “pp # 2” of the physical processor 427.

  In this case, the hypervisor 426 acquires the temperatures of “pp # 2” of the completion processor and “pp # 1” of the standby processor. Here, “pp # 1” of the standby processor has a standby state time (time from time t4 to time t5), and “pp # 2” of the completed processor has a short operation state time. It is assumed that the temperature of “pp # 1” is higher.

  Next, the hypervisor 426 assigns a new process p (process “LP # A0” of the logical processor 425) to the physical processor 427 having a lower temperature (here, “pp # 2” of the completed processor). . Thereby, “pp # 2” of the physical processor 427 is continuously in the operating state. On the other hand, “pp # 1” of the physical processor 427 continues to be in a standby state.

  In the above example, the standby processor has been described as 1. However, a plurality of physical processors 427 may be used as standby processors in accordance with the required power consumption reduction amount. Similarly in this case, the hypervisor 426 assigns a new process p to the physical processor 427 having the lowest temperature.

  Regardless of the configuration illustrated in FIG. 6, the information processing apparatus 420 does not have to have a virtual multiprocessor configuration. That is, the information processing apparatus 420 may include a power control apparatus that allocates a normal process operating on the OS to a physical processor.

  Further, the power control technique of the present embodiment can be applied to a case where tasks are allocated across a plurality of devices in a cluster environment or the like.

  The effect of the present embodiment described above is that the information processing apparatus 420 having a virtual multiprocessor configuration has the same effect as that of the first embodiment.

  The reason is that the hypervisor 426 performs the same operation as that of the power control apparatus 100.

<<< Third Embodiment >>>
Next, a third embodiment of the present invention will be described in detail with reference to the drawings. Hereinafter, the description overlapping with the above description is omitted as long as the description of the present embodiment is not obscured.

=== The process allocation unit 320 ===
The process allocation unit 320 receives the waiting number from the waiting number reception unit 340. The process allocation unit 320 determines a processing apparatus to which a new process is allocated based on the received standby number. In other words, the process allocation unit 320 determines a processing apparatus to be in a standby state based on the received standby number.

  The process allocation unit 320 outputs a change in the state of each processing apparatus (the state illustrated in FIG. 4) to the power saving mode control unit 330. The change in the state is that the processing device in operation has completed the assigned processing, and that the processing device in the standby state is assigned a new processing.

  Each time the process allocation unit 320 updates the control information 180 illustrated in FIG. 4, the process allocation unit 320 outputs the updated control information 180 to the history display unit 350.

=== Power Saving Mode Control Unit 330 ===
The power saving mode control unit 330 receives the state of each processing device, shifts the processing device in the standby state to the power saving mode, and returns the processing device in the operating state from the power saving mode to the normal power mode. Note that the technology for shifting to the power saving mode and the technology for returning from the power saving mode are well known to those skilled in the art, and thus description thereof is omitted.

=== History Display Unit 350 ===
The history display unit 350 stores the received control information 180 as a history. For example, the history display unit 350 records the control information 180 in the storage device 703 shown in FIG.

  In response to the request, the history display unit 350 directly or edits the control information 180 stored in the storage device 703 and outputs the control information 180 as history display information.

  For example, the history display unit 350 outputs the history display information via the output unit 705 shown in FIG. Further, the history display unit 350 may transmit the history display information to a device (not shown) via the communication unit 706 shown in FIG. The history display unit 350 may record the history display information on the recording medium 707 via the storage device 703 shown in FIG.

  The first effect of the present embodiment described above is that, in addition to the effect of the first embodiment, it is possible to easily set the number of processing devices to be in a standby state.

  The reason is that the standby number receiving unit 340 receives the standby number, and the process allocation unit 320 determines a processing device to be put into a standby state based on the standby number.

  The second effect of the present embodiment described above is that power consumption can be more effectively reduced.

  The reason is that the process allocation unit 320 outputs a change in the state of each processing device, and the power saving mode control unit 330 switches each processing device to the power saving mode or the normal power mode based on the change in the state. Because.

  The third effect of the present embodiment described above is that the power control history can be visualized.

  The reason is that the processing allocation unit 320 outputs the control information 180, the history display unit 350 stores the control information 180 as a history, and outputs the control information 180 as it is or after editing in response to the request. It is.
