Description

The present invention relates to an information processing device, a power management method, and a power management program.

For example, a business operator operating a large-scale computing system that consumes a large amount of electric power makes a contract regarding electric power use with an electric power company as necessary. Specifically, the business operator makes a contract to pay an additional fee as a penalty when, for example, the power consumption for each unit time (for example, every 30 minutes) exceeds the upper limit threshold value.

In this case, the business operator needs to prevent the power consumption per unit time from exceeding the upper limit threshold value. Therefore, for example, the business operator periodically acquires the power consumption of the large-scale system in the unit time including the current time, and continuously monitors the acquired power consumption (for example, Patent Documents 1 to 3). reference).

Here, when it becomes necessary to suppress the power consumption in the large-scale calculation system, the business operator stops, for example, a job running in the large-scale calculation system. As a result, the operator can prevent the power consumption of the large-scale calculation system in the unit time including the current time from exceeding the upper limit threshold value.

However, stopping a job running in a large-scale computing system usually requires a stop time according to the job to be stopped. Further, in a large-scale calculation system, power is consumed even after all jobs are stopped. Therefore, the business operator cannot accurately specify the timing when the job needs to be stopped, and may not be able to suppress the power consumption for each unit time to the threshold value or less.

Therefore, in one aspect, it is an object of the present invention to provide an information processing device, a power management method, and a power management program capable of suppressing the power consumption per unit time to a threshold value or less.

In one aspect of the embodiment, the information processing device that stops the job operating in the parallel processing device in which the usable electric energy for each unit time is set is the minimum power consumption of the parallel processing device while the job is stopped. , A storage unit that stores the maximum power consumption that may be consumed by the parallel processing device and the job stop time required to stop a job that is operating in the parallel processing device, and a specification including the current time. The first power consumption is calculated by multiplying the time obtained by subtracting the job stop time from the remaining time until the unit time elapses by the minimum power consumption, and the maximum power consumption is set to the job stop time. The second power consumption amount is calculated by multiplying, and the reference power consumption amount is calculated by subtracting the first power consumption amount and the second power consumption amount from the usable power amount, and the specific unit time is calculated. When the power consumption amount in the above reaches the reference power amount, it has a power control unit for stopping a job in operation in the parallel processing device.

According to one aspect, it is possible to keep the power consumption per unit time below the threshold value.

[Information processing system configuration]
FIG. 1 is a diagram showing an overall configuration of the information processing system 10. The information processing system 10 shown in FIG. 1 includes an information processing device 1, a parallel processing device 2 constituting a large-scale calculation system, and an operation terminal 3. The information processing device 1 and the parallel processing device 2 are each composed of one or more physical machines. Further, the information processing device 1 and the parallel processing device 2 are arranged in, for example, a data center DC.

The operation terminal 3 is, for example, a PC (Personal Computer) in which a business operator inputs information to the information processing device 1. The operation terminal 3 is connected to the data center DC (information processing device 1) via, for example, a network NW.

The information processing device 1 periodically monitors the power consumption of the parallel processing device 2 for each unit time, for example. Then, when the information processing device 1 determines that it is necessary to stop the operating job in the parallel processing device 2, it transmits an instruction to stop the operating job to the parallel processing device 2.

Here, when it becomes necessary to suppress the power consumption in the parallel processing device 2, the business operator stops, for example, a job running in the parallel processing device 2. As a result, the operator can prevent the power consumption of the large-scale calculation system in the unit time including the current time from exceeding the upper limit threshold value.

However, in order to stop a job operating in the parallel processing device 2, a stop time corresponding to the job to be stopped is usually required. Further, in the parallel processing device 2, power is consumed even after all the jobs are stopped. Therefore, the business operator needs to stop the necessary job while considering the time required to stop the operating job, the power consumption while the job is stopped, and the like.

Therefore, the information processing device 1 in the present embodiment has the minimum power consumption of the parallel processing device 2 while the job is stopped, the maximum power consumption that may be consumed by the parallel processing device 2, and the parallel processing device 2. Memorize the job stop time required to stop a running job.

Then, the information processing apparatus 1 multiplies the time obtained by subtracting the job stop time from the remaining time until the unit time including the current time (hereinafter, also referred to as a specific unit time) elapses by the minimum power consumption. Calculate the first power consumption. Further, the information processing apparatus 1 calculates the second power consumption amount by multiplying the job stop time by the maximum power consumption. Further, the information processing device 1 subtracts the first power consumption amount and the second power consumption amount from the upper limit threshold value (hereinafter, also referred to as usable power amount) of the power consumption amount of the parallel processing device 2 for each unit time. By doing so, the reference electric energy is calculated.

After that, when the power consumption amount in a specific unit time reaches the reference power amount, the information processing device 1 stops the job running in the parallel processing device 2.

That is, for example, when all the jobs in operation in the parallel processing device 2 are stopped at the same time, the maximum value of the amount of power that may be consumed from the current time to the lapse of a specific unit time is the first. It can be determined that it is the sum of the power consumption amount and the second power consumption amount. Therefore, when the power consumption up to the current time in a specific unit time reaches the reference power amount, the information processing device 1 simultaneously stops all the jobs in operation in the parallel processing device 2 to obtain a specific unit. It is possible to prevent the power consumption in a specific unit time from exceeding the upper limit threshold value by the timing when the time elapses.

This makes it possible for the information processing device 1 to prevent the power consumption of the parallel processing device 2 for each unit time from exceeding the upper limit threshold value.

On the other hand, when the power consumption in a specific unit time does not reach the reference electric energy calculated in the process of S14 (NO in S15), the information processing apparatus 1 does not perform the process of S16.

This makes it possible for the information processing device 1 to prevent the power consumption of the parallel processing device 2 for each unit time from exceeding the upper limit threshold value.

[Details of the first embodiment]
Next, the details of the first embodiment will be described. 7 to 10 are flowcharts illustrating the details of the power management process according to the first embodiment. 11 to 20 are views for explaining the details of the power management process according to the first embodiment. Hereinafter, the details of the power management process shown in FIGS. 7 to 10 will be described with reference to FIGS. 11 to 20.

As shown in FIG. 7, the information management unit 111 of the information processing device 1 waits until the information storage timing (NO in S21).

Then, when the information storage timing is reached (YES in S21), the information management unit 111 stores the minimum power consumption information 131 including the minimum power consumption of the parallel processing device while the job is stopped in the information storage area 130 (S22). ).

Further, in this case, the information management unit 111 stores the maximum power consumption information 132 including the maximum power consumption that may be consumed in the parallel processing device 2 in the information storage area 130 (S23).

Further, in this case, the information management unit 111 stores the usable power information 133 including the usable power amount for each unit time for which the parallel processing device 2 is permitted to be used by the contract between the business operator and the electric power company. Store in 130 (S24).

Further, in this case, the information management unit 111 stores the job stop time information 134 including the job stop time required to stop the running job in the parallel processing device 2 in the information storage area 130 (S24). Hereinafter, specific examples of the minimum power consumption information 131, the maximum power consumption information 132, the usable power information 133, and the job stop time information 134 will be described.

[Specific example of information stored in the process of S22 to the process of S25]
FIG. 11 is a diagram illustrating specific examples of the minimum power consumption information 131, the maximum power consumption information 132, the usable power information 133, and the job stop time information 134.

The information shown in FIG. 11 includes "minimum power consumption" in which a value indicating the minimum power consumption information 131 is set, "maximum power consumption" in which a value indicating the maximum power consumption information 132 is set, and usable power information 133. It has "usable electric energy" in which a value indicating is set and "job stop time" in which a value indicating job stop time information 134 is set as items.

Specifically, in the information shown in FIG. 11, "400 (W)" is set as the "minimum power consumption" for the information in which the "item number" is "1", and "1200 (maximum power consumption)" is set as the "maximum power consumption". W) ”is set,“ 12000000 (J) ”is set as the“ usable power ”, and“ 300 (seconds) ”is set as the“ job stop time ”.

Returning to FIG. 8, the electric energy acquisition unit 112 of the information processing device 1 waits until the stop determination timing (NO in S31).

Then, when the stop determination timing is reached (YES in S31), the electric energy acquisition unit 112 measures the power consumption of the parallel processing device 2 in a specific unit time including the current time from the electric energy meter of the parallel processing device 2. Acquire (S32). Specifically, the electric energy acquisition unit 112 acquires the electric energy currently indicated by the watt hour meter of the parallel processing device 2.

Subsequently, the time determination unit 113 of the information processing apparatus 1 refers to the unit time information 135 stored in the information storage area 130, and determines the remaining time until a specific unit time including the current time elapses. Identify (S33). Then, the time determination unit 113 determines whether or not the specified remaining time is longer than the job stop time indicated by the job stop time information 134 stored in the information storage area 130 (S33). Hereinafter, a specific example of the unit time information 135 will be described.

[Specific example of unit time information (1)]
12 and 13 are diagrams for explaining a specific example of the unit time information 135.

The unit time information 135 shown in FIG. 12 and the like has "start time" in which the start time of a specific unit time is set and "end time" in which the end time of the specific unit time is set as items. There is.

Specifically, in the unit time information 135 shown in FIG. 12, "10:00" is set as the "start time" and "10:" is set as the "end time" for the information whose "item number" is "1". 30 "is set.

Therefore, for example, when the current time is 10:15, the time determination unit 113 specifies 15 minutes as the remaining time until a specific unit time elapses. Then, for example, as shown in FIG. 11, when the job stop time is 5 minutes (300 seconds), the time determination unit 113 states that the remaining time until a specific unit time elapses is longer than the job stop time. judge.

Returning to FIG. 8, when the remaining time until the lapse of the specific unit time is longer than the job stop time (YES in S34), the power amount calculation unit 114 of the information processing apparatus 1 is in the specific unit including the current time. The time obtained by subtracting the job stop time indicated by the job stop time information 134 stored in the information storage area 130 from the remaining time until the time elapses is calculated (S35). Then, the electric energy calculation unit 114 calculates the first electric energy amount by multiplying the calculated time by the minimum power consumption indicated by the minimum power consumption information 131 stored in the information storage area 130 (S35).

Specifically, in the information described with reference to FIG. 11, the job stop time is set to 5 minutes (300 seconds), and the minimum power consumption is set to 400 (W). Therefore, when the remaining time until the specific unit time elapses is 15 minutes, the electric energy calculation unit 114 is, for example, the time obtained by subtracting the job stop time from the remaining time until the specific unit time elapses. 240000 (J) calculated by multiplying 600 seconds (10 minutes) by 400 (W), which is the minimum power consumption, is calculated as the first power consumption.

Subsequently, the electric energy calculation unit 114 determines the maximum power consumption indicated by the maximum power consumption information 132 stored in the information storage area 130 at the job stop time indicated by the job stop time information 134 stored in the information storage area 130. The second power consumption is calculated by multiplying by (S36).

Specifically, in the information described with reference to FIG. 11, 1200 (W) is set as the maximum power consumption. Therefore, the electric energy calculation unit 114 secondly consumes 360000 (J) calculated by multiplying, for example, the job stop time of 300 seconds (5 minutes) and the maximum power consumption of 1200 (W). Calculated as electric energy.

After that, as shown in FIG. 9, the electric energy calculation unit 114 sets the first power consumption amount calculated in the process of S35 from the available electric energy amount indicated by the usable electric energy information 133 stored in the information storage area 130. , The reference electric energy is calculated by subtracting the second electric energy calculated in the process of S36 (S41).

Specifically, in the information described with reference to FIG. 11, 12000000 (J) is set as the usable electric energy. Therefore, for example, the electric energy calculation unit 114 subtracts 240000 (J) calculated in the process of S35 and 360000 (J) calculated in the process of S36 from the usable electric energy of 12000000 (J). Calculates 600,000 (J).

Then, the job stop unit 115 of the information processing apparatus 1 determines whether or not the power consumption amount acquired in the process of S32 has reached the reference power amount calculated in the process of S41 (S42).

As a result, when it is determined that the reference electric energy has been reached (YES in S43), the job stop unit 115 stops all the jobs in operation in the parallel processing device 2 (S44). On the other hand, when it is determined that the reference electric energy has not been reached (NO in S43), the job stop unit 115 does not perform the process of S44.

That is, when stopping all the jobs in operation in the parallel processing device 2, the maximum value of the amount of power that may be consumed from the current time to the elapse of a specific unit time including the current time is S35. It is the sum of the first power consumption amount calculated by the process of S36 and the second power consumption amount calculated by the process of S36. Therefore, when the information processing device 1 determines that the power consumption up to the current time in a specific unit time has reached the reference power amount, the information processing device 1 stops all the jobs operating in the parallel processing device 2 to specify the specific power consumption. It is possible to prevent the power consumption of the parallel processing device 2 in a unit time from exceeding the upper limit threshold (usable power amount).

This makes it possible for the information processing device 1 to prevent the power consumption of the parallel processing device 2 for each unit time from exceeding the upper limit threshold value.

On the other hand, in the process of S34, when the remaining time until a specific unit time elapses is equal to or less than the job stop time (YES in S34), the reset instruction unit 116 of the information processing apparatus 1 has, as shown in FIG. It is determined whether or not the remaining time specified in the process of S33 is 0 (S51). That is, the reset instruction unit 116 determines whether or not the current time is the time when the current time is switched to the next unit time.

As a result, when it is determined that the remaining time is 0 (YES in S51), the reset instruction unit 116 instructs the watt hour meter of the parallel processing device 2 to reset (S52).

That is, the watt hour meter of the parallel processing device 2 measures the power consumption of the parallel processing device 2 (power consumption up to the current time) in a unit time including the current time. Therefore, the reset instruction unit 116 resets the power consumption indicated by the watt hour meter of the parallel processing device 2 in response to the determination that the unit time including the current time has been switched to the next unit time.

As a result, the watt hour meter of the parallel processing device 2 can start measuring the power consumption of the parallel processing device 2 in the next unit time.

Subsequently, the information management unit 111 updates the unit time information 135 stored in the information storage area 130 so as to indicate the next unit time (S53). Hereinafter, a specific example of the unit time information 135 updated in the process of S53 will be described.

[Specific example of unit time information (2)]
FIG. 13 is a diagram illustrating a specific example of the unit time information 135 updated in the process of S53.

"10:00" and "10:30" are set in the "start time" and "end time" in the unit time information 135 described with reference to FIG. 12, respectively. Therefore, in the process of S53, for example, as shown in FIG. 13, the information management unit 111 sets the "start time" to "10:30", which is the time 30 minutes after "10:00", and sets the "start time" to "10:30". As the "end time", "11:00", which is the time 30 minutes after "10:30", is set.

If it is determined in the processing of S51 that the remaining time is not 0 (NO in S51), the reset instruction unit 116 and the information management unit 111 do not perform the processing of S52 and the processing of S53.

[Specific example of power management processing]
Next, a specific example of the power management process will be described.

FIG. 14 is a diagram illustrating a case where a straight line generated from each of the minimum power consumption, the maximum power consumption, and the usable electric energy at each time included in a specific unit time is represented on a plane. In the plane shown in FIG. 14, the horizontal axis represents time (time from the start to the end of a specific unit time), and the vertical axis represents the power consumption in a specific unit time.

Specifically, the straight line LN01 corresponding to the minimum power consumption and the straight line LN02 corresponding to the maximum power consumption are represented as straight lines increasing with the passage of time, respectively, as shown in FIG. Further, since the straight line LN03 corresponding to the usable electric energy is a value in which the usable electric energy does not change with the passage of time, as shown in FIG. 14, it is a straight line parallel to the horizontal axis and the vertical axis. It is represented as a straight line that intersects at point P01. Further, the straight line LN04 corresponding to the power consumption of the parallel processing device 2 in a specific unit time is expressed as a straight line (polygonal line) transitioning in the region between the straight line LN01 and the straight line LN02 as shown in FIG. ..

Subsequently, FIG. 15 shows the time at which the stop of the job must be started at the latest in order to stop all the jobs operating in the parallel processing device 2 by the elapsed time per unit time on the plane described with reference to FIG. It is a figure explaining the case which expresses (hereinafter, also referred to as a grace time).

Specifically, as shown in FIG. 15, the grace time is expressed as a time that goes back from the time when a specific unit time elapses to the job stop time.

In the process of S34, the case where the remaining time until the lapse of a specific unit time is longer than the job stop time is the case where the current time has not reached the grace time.

Then, FIG. 16 is a straight line parallel to the straight line LN02 in the plane described with reference to FIG. 15, and is a straight line passing through the point P02 when the horizontal axis of the points on the straight line LN03 is the unit time elapsed time. A diagram illustrating a case where a certain LN12 and a straight line LN11 which is a straight line parallel to the straight line LN01 and which is a straight line passing through the point P03 when the horizontal axis of the points on the straight line LN12 is the grace time is expressed. Is.

In the example shown in FIG. 16, the difference between the value on the vertical axis of the point when the horizontal axis of the points on the straight line LN01 is the current time and the value on the vertical axis of the point P03 is calculated in the process of S35. Corresponds to the first power consumption. Further, in the example shown in FIG. 16, the difference between the value on the vertical axis of the point P01 and the value on the vertical axis of the point P03 corresponds to the second power consumption calculated in the process of S36.

Further, FIG. 17 is a diagram for explaining a straight line LN21 which is a straight line corresponding to a reference electric energy amount (reference electric energy amount calculated by the process of S41) at each time included in a specific unit time.

Specifically, the straight line LN21 corresponding to the reference electric energy is represented as a straight line corresponding to the horizontal axis from 0 to the grace time in the straight line LN11 described with reference to FIG.

18 to 20 are views for explaining the relationship between the straight line LN04 described with reference to FIG. 14 and the straight line LN21 described with reference to FIG.

Specifically, in the example shown in FIG. 18, when the straight line LN04 and the straight line LN21 intersect, the power consumption acquired from the watt hour meter of the parallel processing device 2 is the reference power as described in the process of S43. When the quantity is reached. Therefore, in this case, the job stop unit 115 stops all the operating jobs at the timing when the straight line LN04 and the straight line LN21 intersect, as described in the process of S44.

As a result, as shown in FIG. 18, the information processing device 1 always consumes the maximum power consumption in the parallel processing device 2 from the start of the job stop to the completion of the job stop. Even in this case, it is possible to control the power consumption in a specific unit time (power consumption up to the elapsed time of the unit time) so as not to exceed the usable power amount.

On the other hand, when the stop of the operating job is started at a later timing than the timing at which the straight line LN04 and the straight line LN21 intersect, the power consumption in a specific unit time can be used as shown in FIG. It may exceed the amount of electricity.

That is, when the straight line LN04 and the straight line LN21 intersect, the information processing device 1 consumes power in a specific unit time on condition that all the operating jobs are stopped at the timing when the straight line LN04 and the straight line LN21 intersect. It becomes possible to prevent the amount from exceeding the usable electric energy.

As shown in FIG. 20, when the straight line LN04 and the straight line LN21 do not intersect, the power consumption in the parallel processing device 2 is always the maximum power consumption from the grace time to the elapsed time of the unit time. Even if there is, the power consumption in a specific unit time does not exceed the usable power amount.

[Outline of the second embodiment]
Next, the second embodiment will be described.

In the power management process according to the second embodiment, the information processing device 1 performs parallel processing at that time even when the power consumption amount acquired from the watt hour meter of the parallel processing device 2 reaches the reference electric energy. When the power consumption of the device 2 is less than the maximum power consumption, only the jobs that need to be stopped among the jobs operating in the parallel processing device 2 are stopped.

As a result, the information processing device 1 needs to stop all the jobs operating in the parallel processing device 2 even when the power consumption obtained from the watt-hour meter of the parallel processing device 2 reaches the reference electric energy. Will disappear. Therefore, the information processing device 1 can suppress the influence of stopping the operating job on the parallel processing device 2 (various processes being executed in the parallel processing device 2).

The power management process in the second embodiment is different from the power management process in the first embodiment only in terms of the content of the process performed in the process of S44. Therefore, among the power management processes in the second embodiment, only the process of S44 will be described below.

[Details of the second embodiment]
21 and 22 are flowcharts illustrating a part of the details of the power management process according to the second embodiment. Specifically, FIGS. 21 and 22 are diagrams for explaining the process of S44 among the processes in the second embodiment.

When the job stop unit 115 determines in the process of S43 that the power consumption amount acquired in the process of S32 has reached the reference power amount calculated in the process of S41 (YES in S43), the job stop unit 115 executes a new job. Instructs the parallel processing apparatus 2 to stop the start of (S61).

Then, the job stop unit 115 refers to, for example, the electric energy information (not shown) stored in the information storage area 130, and calculates the current power consumption in the parallel processing device 2 (S62). The electric energy information is, for example, information in which the electric energy acquired in the process of S32 is accumulated.

Specifically, for example, in the processing of S62, the job stop unit 115 refers to the power consumption amount corresponding to the recently acquired predetermined information among the information included in the electric energy amount information, and causes the parallel processing apparatus 2 to refer to the power consumption amount. It may be used to calculate the current power consumption.

More specifically, for example, the power consumption obtained in the processing of S32 this time from the watt hour meter of the parallel processing device 2 is 480000 (J), and the processing of the previous S32 (for example, the processing of S32 this time). When the power consumption acquired in the processing of S32 performed 60 seconds before the above is 420,000 (J), the job stop unit 115 subtracts 420,000 (J) from 480000 (J) to 60000. (J) is calculated. Then, in this case, the job stop unit 115 calculates, for example, 1000 (W) calculated by dividing the calculated 60000 (J) by 60 (seconds) as the current power consumption in the parallel processing device 2.

Subsequently, the job stop unit 115 calculates the third power consumption amount by multiplying the job stop time indicated by the job stop time information 134 stored in the information storage area 130 by the power consumption calculated in the process of S62. (S63).

That is, the job stop unit 115 cancels the start of execution of a new job in the process of S61. Therefore, in the information processing device 1, the power consumption calculated by multiplying the current power consumption in the parallel processing device 2 (the power consumption calculated in the processing of S62) and the job stop time is the power consumption in the parallel processing device 2. It is possible to determine that it is the maximum value of the amount of power consumed until the running job is stopped. Therefore, the job stop unit 115 calculates the third power consumption amount by multiplying the current power consumption in the parallel processing device 2 and the job stop time in the processing of S63.

Specifically, in the information described with reference to FIG. 11, 300 (seconds) is set as the job stop time. Therefore, when the power consumption calculated in the process of S62 is 1000 (W), the job stop unit 115 calculates 300,000 (J) as the third power consumption.

Then, the job stop unit 115 calculates the power consumption amount acquired in the processing of S32 and the third consumption calculated in the processing of S63 from the usable power amount indicated by the usable power information 133 stored in the information storage area 130. The electric energy is calculated by subtracting the electric energy from the electric energy (S64).

That is, the job stop unit 115 is consumed from the available power amount to the power consumption amount of the parallel processing device 2 in a specific unit time including the current time and to stop the job operating in the parallel processing device 2. Subtract the maximum value of electric energy. As a result, the job stop unit 115 determines the amount of electric power that can be consumed by the parallel processing device 2 between the time when the stop of the job running in the parallel processing device 2 is completed and the time when a specific unit time elapses. It becomes possible to calculate.

Specifically, in the information described with reference to FIG. 11, 12000000 (J) is set as the usable electric energy. Therefore, for example, when the power consumption acquired in the processing of S32 is 480000 (J) and the third power consumption calculated in the processing of S63 is 300,000 (J), the job stop unit 115 of the job stop unit 115 of S64. In the process, 420000 (J) is calculated by subtracting 480000 (J) and 300,000 (J) from 120000 (J).

After that, the job stop unit 115 transfers the electric energy calculated in the process of S64 from the remaining time until a specific unit time including the current time elapses to the job stop time information 134 stored in the information storage area 130. The reference power consumption is calculated by dividing the indicated job stop time by the subtracted time (S65).

That is, the job stop unit 115 calculates the power that can be consumed by the parallel processing device 2 as the reference power consumption from the current time to the elapse of a specific unit time.

Specifically, for example, when the time obtained by subtracting the job stop time from the remaining time until a specific unit time elapses is 900 seconds and the electric energy calculated by the processing of S64 is 420,000 (J), the job The stop unit 115 calculates about 467 (W) calculated by dividing 420000 (J) by 900 (seconds) as the reference power consumption.

Subsequently, as shown in FIG. 22, the job stop unit 115 consumes the total power consumption of the jobs operating in the parallel processing device 2 from the power consumption calculated in the processing of S62 to the reference consumption calculated in the processing of S65. Identify one or more jobs that are equal to or greater than the power consumption obtained by subtracting the power (S71).

That is, the job stop unit 115 is among the jobs operating in the parallel processing device 2 in order to reduce the power consumption from the current time to the remaining time until the lapse of a specific unit time to be equal to or less than the reference power consumption. Identify one or more jobs that need to be stopped.

Specifically, the job stop unit 115 may, for example, preferentially stop a job having a large power consumption among the jobs operating in the parallel processing device 2. Further, the job stop unit 115 may, for example, preferentially stop a job having a new job execution start timing among the jobs operating in the parallel processing device 2. Further, the job stop unit 115 may preferentially stop a job that has been stopped less frequently in the power management process performed in the past among the jobs that are operating in the parallel processing device 2. Further, the job stop unit 115 may preferentially stop a job having a low priority (importance) predetermined by the business operator, for example.

After that, the job stop unit 115 stops each of one or more jobs specified in the process of S71 among the jobs operating in the parallel processing device 2 (S72).

As a result, the information processing device 1 stops all jobs operating in the parallel processing device 2 even when the power consumption obtained from the watt-hour meter of the parallel processing device 2 reaches the reference electric energy. No need. Therefore, the information processing device 1 can suppress the influence of the stoppage of the operating job on the parallel processing device 2.

When the power consumption of the job operating in the parallel processing device 2 is a job that may change during the operation, the job stop unit 115 sets the job in operation in the parallel processing device 2 in the processing of S62. The maximum value of the power that may be consumed by the user may be calculated as the current power consumption.

As a result, the information processing device 1 identifies a job that needs to be stopped even if the power consumption of the job being operated in the parallel processing device 2 is a job that may change during the operation. Will be possible.
