  The overall operation processing procedure in the processor management control according to the present embodiment is as a basic procedure, in which a management device functioning as a management-side control means acquires the measured temperature information of the processor (for example, as shown in FIG. 2). Step S11: Temperature information acquisition step) When the acquired temperature exceeds a threshold value, first control is performed to lower the operating frequency of the processor (for example, a step consisting of steps S12 and S16 shown in FIG. 2: first control). Step) When the processing performance of the processor is lowered in a state where the operating frequency is lowered, the second control for dynamically adding the spare cell including the spare processor is performed (for example, step S17 and step shown in FIG. 2).

In this case, when the second control is performed, if the cooling function is maximum and the processing performance of the processor is lowered in a state where the operating frequency is lowered to the reduction limit, the spare processor including the spare processor is included. Cells can be added dynamically.

(Detailed operation)
This will be described in detail below.
As shown in FIG. 2, first, the management software of the control terminal device that functions as the management-side control means starts accessing the system controller 50 of the management target device 20 through the NIC 12.

  Furthermore, the control terminal device 10 that functions as a management-side control unit acquires the current temperature of the CPU from the system controller 50 by the IPMI protocol (step S11: processor temperature information acquisition step or processor temperature information acquisition function).

  Next, the control terminal device 10 functioning as the management-side control means compares the acquired temperature information value with a threshold value (pre-set temperature threshold information) or temperature control condition information set in advance in the management software. Then, a process for determining whether or not the acquired temperature exceeds the threshold is performed (step S12: temperature threshold determination step or temperature threshold determination function).

In the determination process of step S12, when it is determined that the acquired temperature exceeds the threshold value, the control terminal device 10 functioning as a management-side control unit proceeds to step S13.
On the other hand, in the determination process of step S12, when it is determined that the acquired temperature does not exceed the threshold value, the control terminal device 10 functioning as a management-side control unit proceeds to step S19.

  Subsequently, in step S13, the control terminal device 10 that functions as a management-side control unit acquires information on the rotation speed of the fan from the system controller 50 by the IPMI protocol (rotation speed information acquisition step or rotation speed information acquisition function). A process of determining whether or not the acquired rotation speed information is the maximum rotation speed is performed (step S13: rotation speed determination step or rotation speed determination function).

When it is determined in the determination process of step S13 that the acquired number of rotations is the maximum, the control terminal device 10 functioning as a management-side control unit proceeds to step S15.
On the other hand, if it is determined in step S13 that the acquired number of rotations is not the maximum, the control terminal device 10 functioning as a management-side control unit proceeds to step S14.

That is, if it is not the maximum, the control terminal device 10 that functions as the management-side control means controls the rotation speed of the fan and sets the rotation speed to the maximum (step S14: rotation speed setting control step or rotation speed setting). Control function).
And it returns to step S11 again and continues monitoring of a state.

On the other hand, in the case of the maximum, the control terminal device 10 (the management software 11) functioning as the management-side control means accesses the operating system 31 operating in the first partition being monitored, and the CPU operating mode The processor operation mode confirmation step or the processor operation mode confirmation function is performed.
Then, the control terminal device 10 functioning as the management-side control means performs a process of determining whether or not the operation mode of the CPU is operating in the power saving mode (step S15: power saving mode determination step or power saving). Mode judgment function).

In the determination process of step S15, when it is determined that the acquired operation mode is the power saving mode, the control terminal device 10 functioning as a management-side control unit proceeds to step S17.
On the other hand, in the determination process of step S15, when it is determined that the acquired operation mode is not the power saving mode, the control terminal device 10 functioning as a management-side control unit proceeds to step S16.

That is, when not operating in the power saving mode, the control terminal device 10 that functions as a management-side control unit uses the power saving function of the operating system 31. Specifically, the control terminal device 10 functioning as a management-side control means uses ICPI P-State control from the clock control I / F 32 to lower the execution clock (operating frequency) of the CPU 34 and reduce power consumption. At the same time, a setting is made to lower the temperature of the CPU 34 (step S16: first operating frequency change control step or first operating frequency change control function).
Thereafter, the process returns to step S11 to monitor the state.

  Then, the control terminal device 10 functioning as a management-side control means performs a process of determining whether or not the CPU execution clock has decreased to a limit value (settable minimum value) (step S17: Availability of reaching operating frequency limit value). Judgment step or operation frequency limit value reachability determination function).

In the determination process of step S17, when it is determined that the execution clock is the limit value, the control terminal device 10 functioning as a management-side control unit proceeds to step S20.
On the other hand, in the determination process of step S17, when it is determined that the execution clock is not the limit value, the control terminal device 10 functioning as a management-side control unit proceeds to step S18.
That is, in the case where no improvement is observed in the temperature up to this point, the control terminal device 10 functioning as the management-side control means can set the execution clock (operating frequency) of the CPU 34 to the minimum value that can be set. A drop process is performed (step S18: second operating frequency change control step or second operating frequency change control function).
Thereafter, the process returns to step S11 to monitor the state.

  On the other hand, when the temperature does not exceed the threshold value in the determination process of step S12, the control terminal device 10 functioning as the management-side control means operates in the power saving mode, and OS (operating system) tasks are accumulated in the queue. (Step S19: queue staying state judging step or queue staying state judging function).

In the determination process of step S19, when it is determined that the task is accumulated in the queue, the control terminal device 10 functioning as a management-side control unit proceeds to step S20.
On the other hand, in the determination process of step S19, when it is determined that the task is not accumulated in the queue, the control terminal device 10 functioning as the management-side control unit returns to step S11 and monitors the state.

  In this way, when the temperature has not improved in the above procedure (“Yes” in step S17), or the temperature has been improved, the performance counter of the operating system 31 and the status of the process When it is determined that the tasks are queued and the processing performance is remarkably reduced (“Yes” in step S19), the control terminal device 10 functioning as the management-side control unit performs step S20.

That is, the control terminal device 10 that functions as a management-side control unit adds the spare cell 40 (step S20: spare cell addition step or spare cell addition function).
Specifically, the control terminal device 10 functioning as a management-side control means assigns the spare cell 40 to the first partition, and increases the number of CPUs by one from the operating system 31 (the CPU 34 of the main cell and the CPU 44 of the spare cell). ).
Thus, the processing executed in the operating system 31 is distributed by the two CPUs (CPU 34 and CPU 44), thereby improving the performance and stabilizing the temperature while maintaining the processing performance.
At this time, the management software 11 stands and stores a flag indicating that the spare cell 40 has been added in the management target partition in a specific storage area.

(Cell separation procedure)
Next, referring to FIG. 3, the procedure for reducing the power consumption by disconnecting the additionally allocated cell and turning off the power when the temperature is stable and the amount of processing of the operating system is reduced. explain.

  First, the control terminal device 10 that functions as a management-side control unit acquires IPMI information from the system controller 50 and acquires CPU temperature information (step S31: processor temperature information acquisition step or processor temperature information acquisition function).

  Subsequently, the control terminal device 10 functioning as the management-side control means checks whether or not a flag indicating that a spare cell is added (a spare cell addition flag) is set in step S20 shown in FIG. Processing for determining whether or not addition has been performed is performed (step S32: standby cell addition presence / absence determination step or spare cell addition presence / absence determination function).

  If it is determined in the determination process of step S32 that a spare cell has not been added, the control terminal device 10 functioning as a management-side control unit proceeds to step S37.

  On the other hand, if it is determined in step S32 that a spare cell has been added, the control terminal device 10 functioning as a management-side control unit determines whether the temperature of the partition is appropriate. Processing is performed (step S33: partition temperature determination step or partition temperature determination function).

  If it is determined in the determination process in step S33 that the partition temperature is not an appropriate temperature, the control terminal device 10 functioning as a management-side control unit returns to step S31 and monitors the state.

On the other hand, in the determination process of step S33, when it is determined that the partition temperature is an appropriate temperature, the control terminal device 10 functioning as a management-side control unit performs a process of separating the added spare cell from the partition (step S34). : Additional cell separation step or additional cell separation function).
At this time, the control terminal apparatus 10 functioning as a management-side control unit performs a process of deleting a flag (a spare cell addition flag) indicating that the spare cell 40 has been added.
In addition, the control terminal device 10 that functions as a management-side control unit also performs a process of turning off the power of the separated spare cell.

  After that, the control terminal device 10 that functions as the management-side control means is in a state where tasks are accumulated in the queue in the operating system 31 due to the effect of disconnecting the spare cell 40 after a certain period of time. (Step S35: queue separation state determination step after separation or queue retention state determination function after separation).

  In the determination process of step S35, when it is determined that the task is not accumulated in the queue after disconnection, the control terminal device 10 functioning as a management-side control unit proceeds to step S37.

On the other hand, in the determination process of step S35, when it is determined that the task is queued after the disconnection, the control terminal device 10 functioning as the management-side control unit performs the maximum execution of the CPU operating in the power saving mode. Processing to raise the clock is performed (step S36: execution maximum operation frequency increasing step or execution maximum operation frequency increasing function).
Thereafter, the control terminal device 10 functioning as a management-side control unit returns to step S31 and monitors the state.

  Next, since the state of the partition to be managed has returned to the state before the addition of the cell, the process of the temperature management flow shown in FIG. 2 is performed again and monitoring is continued (step S37: temperature re-management step or temperature). Re-management function).

  As described above, according to the present embodiment, when the temperature exceeds a set threshold, the processor clock is reduced to stabilize the temperature, and at this time, the device operates on this device. If a delay in task processing occurs due to lowering the processor execution clock in an operating system, adding spare cells reduces the processor processing load while maintaining the temperature constant, affecting operation. Do not.

  That is, in the present embodiment, as a management target device, for example, an IPMI (Intelligent Platform Management Interface) (especially a CPU temperature information acquisition function) and a plurality of cells configured by a CPU, a memory, and a system board corresponding to ICPI are provided. It can be a target computer.

Here, the management device (control terminal device) cooperates with the management target device, manages the temperature of the CPU with IPMI, and uses the ICPI P-State control when the temperature exceeds the danger threshold, Lower the execution clock, enter power saving mode, and lower the temperature.
At this time, the management device (control terminal device) cooperated with the management target device, and the task processing delay occurred due to the CPU execution clock being lowered in the operating system running on the management target device. In this case, by adding a spare cell, the partition (partition) is expanded, the load of the CPU processing is reduced, and the operation is not affected while the temperature of the management target device is kept constant.

  In addition, the management device (control terminal device) cooperates with the management target device, disconnects the dynamically added partition when the operating system load decreases, and turns off the power of the added cell. Save money. By doing so, hot spots in the data center are eliminated, and air conditioning power is reduced.

In this way, the management device (control terminal device) manages the temperature of the management target device that has a plurality of CPUs and can create a partition for each cell in which the CPU exists, in cooperation with the management target device. When the temperature exceeds a set threshold value, the CPU operates in a power saving mode to reduce the maximum execution clock and stabilize the temperature.
Further, the management device (control terminal device) cooperates with the management target device, and at this time, a task processing delay occurs due to the CPU execution clock being lowered in the operating system operating on the management target device. In this case, by adding a spare cell, the partition (partition) is expanded while keeping the temperature constant, the CPU processing load is reduced, and the operation is not affected.

  Furthermore, the management device (control terminal device) cooperates with the management target device, and when the load of the operating system decreases, the management device (control terminal device) disconnects the dynamically added partition and powers off the added cell. Save money.

Therefore, the following effects can be achieved.
The first effect is that the task processing capability of the operating system can be maintained even if the CPU execution clock is lowered in order to lower the temperature of the management target device.
The reason is that by dynamically adding a cell to a partition, the operating software has an increased number of CPUs and can perform parallel processing.

The second effect is that it is possible to minimize power consumption for temperature management.
The reason is that it is possible to contribute to power saving by reducing the execution clock of the CPU.
In addition, since the temperature is stabilized in the system without depending on the outside air temperature, the temperature can be stabilized without performing an act of lowering the set temperature of the air conditioning.
Furthermore, when the processing amount of the operating system is reduced, it is possible to cut off the added cell from the partition and turn off the power so as not to use power as much as possible.
