Description

  The present invention relates to a power control system and a power control method for reducing unnecessary power consumption.

  A power control system for reducing power consumption is known in storage and data centers. This power control system predicts a future load from stored past information, controls the state of the apparatus based on the result, and reduces unnecessary power consumption.

  An example of a power control system is described in Patent Document 1. The job scheduling apparatus described in Patent Document 1 predicts an increase in power consumption and an increase in temperature of all computers due to job input. Further, the job scheduling apparatus determines a computer to which the desired job is assigned according to the prediction result.

  In addition, the storage system described in Patent Document 2 controls the power ON / OFF of the storage without causing performance degradation due to an input / output error.

  The load management device described in Patent Document 3 predicts the total number of future accesses, estimates the load of the server group from the prediction result, and controls the power saving state and the operating state.

  In addition, the load management device described in Patent Document 4 calculates an estimate of the electricity price from the load further estimated in the load management device described in Patent Document 3, and can be replaced with a cheaper resource.

  However, in the apparatus described in Patent Document 1 described above, the job is controlled only by the predicted temperature. Therefore, depending on the state of the computer, even if the temperature rise value is large, the power consumption is not necessarily large. Therefore, there is a problem that this control is not appropriate from the viewpoint of power consumption reduction. Further, the storage system described in Patent Literature 2, the load management device described in Patent Literature 3, and the load management device described in Patent Literature 4 reduce resources by reducing resources according to the processing status of the system. Therefore, there is a problem that the system must be fully operated at the time of power consumption peak and control that does not exceed the upper limit value of power cannot be realized.

  An object of the present invention is to provide a power control system that can solve the above-described problems.

The first power control system according to one aspect of the present invention is:
A power consumption storage unit storing past power consumption data for each server;
A power consumption measuring unit that measures current power consumption for each server;
Based on the predicted power consumption predicted from the past power data output from the power consumption storage unit and the current power output output from the power consumption measurement unit at the time of job submission, the power consumption of the server set in advance is set. It is determined whether or not the upper limit value is exceeded, and if it exceeds, a control unit that performs control to delay the job submission timing is provided.

A first power control method according to an aspect of the present invention is based on past power consumption data output from a power consumption storage unit for each server and current power consumption output from a power consumption measurement unit for each server when a job is submitted. The control unit predicts the predicted power consumption,
Based on the predicted power consumption, the control unit determines whether it exceeds a preset upper limit value of power consumption of the server,
If it exceeds, control is performed to delay the job submission timing.

  According to the present invention, it is possible to obtain an effect that it is possible to realize control that does not exceed the upper limit value of power even at the time of power peak.

[First Embodiment]
FIG. 1 is a block diagram showing a configuration of a power control system 100 according to the first embodiment of the present invention. Referring to FIG. 1, a power control system 100 includes a network 101, a control unit 102 connected to the network 101, and servers 111 (server A) and 112 (server B). Each of the servers 111 and 112 includes a power consumption storage unit 121 and a power consumption measurement unit 122. Servers other than the servers 111 and 112 may be connected to the network 101, and the number of servers connected is not limited.

  In the power control system 100 according to the first embodiment, when a job is input to the servers 111 and 112, the control unit 102 predicts the power consumption after the job is input from the past power consumption data and the current power consumption. Based on the predicted power consumption, the control unit 102 determines whether or not a preset upper limit value of power consumption of the server is exceeded. If it is determined that the number exceeds, the control unit 102 performs control to delay the job submission timing. Therefore, the power control system 100 according to the first embodiment can realize control that does not exceed the upper limit value of power even during peak power consumption.

  Next, the configuration of the power control system 100 in the first embodiment will be described.

  The power consumption storage unit 121 stores, for each user, the number of times a job has been submitted to the server 111 by the user in the past (number of times of job submission) and an average value of the increase in power consumption when the job is submitted (past power data). Remember. The past power data is, in other words, an increment of power consumption at the time of job submission for each user, and is stored for each server. The power consumption storage unit 121 also stores an upper limit value (peak power) of power consumption determined for each server.

  The power consumption measuring unit 122 measures the current power consumption of the server 111. Further, the power consumption measuring unit 122 measures the increase in power consumption that occurs when a job is submitted by measuring the power consumption of the server during job processing.

  Based on the operation by the user, the control unit 102 receives the designation of the job and the submission server (server 111 or 112), the designation of the priority of job processing, and the designation of performance, and determines the job submission timing based on these designations. You may control. Further, the control unit 102 may control the server 111 such that the higher the job processing priority is, the higher the system usage fee is collected from the user. In addition, the control unit 102 updates and outputs data that is referred to during job input control. The data updated and output during job submission control are past power data stored in the power consumption storage unit 121 of each server, the number of job submissions, and peak power.

  The job processing priority received by the control unit 102 includes an allowable value of the job submission waiting time and a charge collected from the user. In this case, for example, with respect to the job input server, the control unit 102 sets a lower waiting time tolerance and higher fee as the priority is higher.

  Note that the control unit 102 may include a CPU (Central Processing Unit) and a storage medium storing a program, and execute control operations described below based on the program stored in the storage medium.

  The server 112 and other servers have the same configuration as the server 111.

  The operation of the power control system 100 configured as described above will be described with reference to the flowchart of FIG.

  FIG. 2 is a flowchart illustrating an outline of job assignment operation in the power control system 100 according to the first embodiment.

  As shown in FIG. 2, it is assumed that the control unit 102 first receives a newly submitted job. In this case, the control unit 102 determines a job submission server by user selection (step S101).

  Next, the control unit 102 extracts past power data stored in the power consumption storage unit 121 of the job input server and current power consumption measured by the power consumption measurement unit 122 (step S102).

  Here, the control unit 102 determines whether or not past power data is registered in the power consumption storage unit 121 (step S103). When it is determined that the control unit 102 has been registered, the past power data is added to the current power consumption, and the added value is generated as predicted power consumption data (step S104).

  If there is no past power data in the power consumption storage unit 121, the control unit 102 calculates the average of the past power data of all users stored in the power consumption storage unit 121 and sets it as the past power data of the job input user. Then, the data is stored in the power consumption storage unit 121 (step S105). Similarly to the case where past power data is registered in the power consumption storage unit 121, the control unit 102 generates a value obtained by adding the past power data to the current power consumption as predicted power consumption data (step S104).

  Next, the control unit 102 confirms the peak power stored in the power consumption storage unit 121 of the job input server and compares it with predicted power consumption data (hereinafter also simply referred to as predicted power consumption) (step S106). .

  If the predicted power consumption exceeds the peak power, the control unit 102 determines that one of the jobs already executed on the job submission server until the job submission waiting time exceeds the allowable value specified by the user. Wait until completion (step S107). As a result, the job input timing can be delayed until the processing of one job currently being processed is completed.

  When one job is completed, the current power consumption decreases, and thus the predicted power consumption decreases. When the waiting time has not reached the allowable value (No in Step S111), the control unit 102 executes Steps S104 and 106, and again compares the peak power and the predicted power consumption.

  If the predicted power consumption is lower than the peak power, the control unit 102 submits the job to the job submission server (step S108).

  After the job is submitted, the power consumption measurement unit 122 measures an increase in power consumption due to the job submission (step S109), the control unit 102 reads the increase in power consumption of the job from the power consumption measurement unit 122, and the user has received the past. The number of job submissions is read from the power consumption storage unit 121. Next, the control unit 102 newly calculates an average value by the formula of (past power data × number of recordings + increased power consumption) / (number of recordings + 1), adds 1 to the number of job submissions, and consumes each. Output to the power storage unit 121. The power consumption storage unit 121 stores past power data and the number of job submissions (step S110).

  The operation of the power control system 100 when the job submission waiting time exceeds the allowable value according to the priority specified by the user (Yes in step S111) will be described with reference to the flowchart shown in FIG.

  If the waiting time exceeds the allowable value, the job submission user's request cannot be satisfied. In this case, the control unit 102 of the power control system 100 reduces the system usage fee for the user by a certain amount corresponding to the penalty (step S112). Specifically, the control unit 102 controls the usage fee to be lowered via a charging system (not shown) of the job input server or another charging server.

  Thereafter, similarly to step S104 to step S111, the control unit 102 calculates predicted power consumption (step S113) and compares whether or not the peak power is exceeded (step S114). When exceeding, the control unit 102 waits for completion of one of the jobs being executed (step S115), and again calculates the predicted power consumption and compares it with the peak power (steps S113 and S114).

  When the predicted power consumption is lower than the peak power, the control unit 102 inputs a job (step S108) as in the case where the predicted power consumption is lower than the beginning, and the power consumption measurement unit 122 measures an increase in power consumption due to job input (step S108). S109). The control unit 102 updates the past power data and the number of job submissions, and stores them in the power consumption storage unit 121 (step S110).

  Thus, the power control system 100 ends the job assignment operation.

  Next, effects of the first exemplary embodiment of the present invention will be described.

  The power control system according to the present embodiment described above can realize control that does not exceed the upper limit value of power even during peak power consumption.

  This is because the following configuration is included. That is, first, the control unit 102 predicts power after job submission based on past power data and current power consumption. Secondly, the control unit 102 determines whether or not the predicted power and the upper limit value (peak power) of the power consumption determined for each server are exceeded. When the upper limit value of the power consumption of the server is exceeded, the control unit 102 performs control to delay the job submission timing. As a result, when the predicted power exceeds the peak power, the control unit 102 performs control that does not submit a job until the predicted power falls, so that it is possible to realize control that does not exceed the upper limit value of power even during peak power consumption. Is obtained.

[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. 4 is a block diagram showing a configuration of a power control system 200 according to the second embodiment of the present invention.

  Referring to FIG. 4, the power control system 200 in the present embodiment further includes a power management unit 203 and an idling state power consumption storage unit 204 as compared with that in the first embodiment.

  The power management unit 203 manages the power state including the start and stop of the power of each of the servers 111 and 112 connected to the network 101 under the control of the control unit 102.

  The idling state power consumption storage unit 204 stores the power consumption when no jobs are input (also referred to as an idling state) for all the servers 111 and 112 connected to the network 101. The control unit 102 measures the power consumption of each server when the job is not submitted (idling state) by the power consumption measuring unit 122 and stores the measured value in the idling state power consumption storage unit 204 for each server. Also good.

  Next, the operation of the power control system 200 will be described with reference to the flowcharts shown in FIGS. 5, 6, 7, 8, 9, and 10.

  FIG. 5, FIG. 6, FIG. 7, FIG. 8, and FIG. 9 are flowcharts showing an outline of the job assignment operation in the power control system 200 in the second embodiment.

  Referring to FIG. 5, first, the control unit 102 determines a job submission server, compares the predicted power consumption with past power data, and the job submission waiting time exceeds the allowable value according to the priority specified by the user. Up to the process until the job input is delayed until the predicted power consumption falls below the peak power, the process is the same as steps S101 to S111 of the first embodiment (steps S201 to S211).

  The operation of the power control system 200 when the job submission waiting time exceeds the allowable value according to the priority designated by the user (Yes in step S211) will be described with reference to the flowchart shown in FIG.

  Since the job submission waiting time exceeds an allowable value, the power control system 200 needs to investigate a server that can urgently submit a job.

  The control unit 102 monitors the operating state of each server, for example, by monitoring the power supply state in the power management unit 203, and there are other servers in operation other than the server (for example, the server 111) scheduled to submit jobs. Whether or not (step S212).

  When there is an active server, the control unit 102 checks whether or not the server (for example, the server 112) has a performance capable of submitting a job (step S213).

  If there is a performance that can be submitted, the control unit 102 checks whether or not the server (112) waits for a job submission (step S214).

  When there is no job submission waiting, the control unit 102 submits a job at the server (step S208 in FIG. 5).

  The subsequent steps are the same as those in the first embodiment (steps S208 to S210).

  When there is a job submission wait or when the performance is not sufficient to submit the job, the control unit 102 checks whether there is any other active server, and if so, investigates similarly (steps S212 to S214).

  The control unit 102 examines all operating servers, and describes the operation of the power control system 200 when there is no server to which a job can be input (No in step S212), with reference to the flowchart shown in FIG.

  First, the control unit 102 sets Wm as the overall surplus power of each of the servers 111 and 112 connected to the network 101. Here, initialization is performed with Wm = 0 (step S215).

  The control unit 102 checks whether the gap between the peak power of the server and the current power consumption exceeds a threshold, for example, 100 W (step S216).

  If it exceeds, the control unit 102 updates the peak power stored in the power consumption storage unit 121 of the server by reducing it by 50 W (step S217). The decrease in peak power must be smaller than the above threshold. Next, the control unit 102 adds the power 50W corresponding to the reduced peak power to the surplus power Wm. Specifically, Wm = Wm + 50 is added (step S218).

  The control unit 102 checks whether there is any other server other than the server that is scheduled to submit the job (step S219). When there is an operating server, the control unit 102 repeats the above processing for the operating server (steps S216 to S219).

  Next, the control unit 102 checks whether there is a stopped server that satisfies the customer's request from among the servers 111 and 112 connected to the network 101 (step S220).

  When there is a stopped server, the control unit 102 confirms the idling state power consumption of the server stored in the idling state power consumption storage unit 204 (step S221). When the surplus power Wm is larger than the idle state power consumption of the server +100 W (100 W is a threshold value in step S216) (step S222), the power management unit 203 turns on the server and starts it (step S223). The control unit 102 submits a job at the activated server (step S208 in FIG. 5).

  The subsequent steps are the same as those in the first embodiment.

  If the surplus power Wm is less than the idle state power consumption of the server +100 W, the power is not turned on, and the control unit 102 repeats the above processing until it determines that there is no other stopped server (steps S220 to S222). .

  The operation of the power control system 200 (No in step S220) when all the stopped servers are investigated and no server can be turned on will be described with reference to the flowchart shown in FIG.

  First, the control unit 102 first selects a server designated by the user as a job submission server (step S224).

  Next, with respect to the server first designated by the user, the control unit 102 stores the past power data stored in the power consumption storage unit 121 in the current power consumption measured by the power consumption measurement unit 122 (in steps S203 and S205). A value obtained by adding the past power data of the server specified by the user first is generated as predicted power consumption data (step S225). The predicted power consumption data of the server designated by the user first has already been calculated in step S204, but since the current power consumption may have changed, it is calculated again in this step.

  Next, the control unit 102 adds the peak power stored in the power consumption storage unit 121 of the server first designated by the user and the margin power Wm, and compares it with the predicted power consumption (step S226). When the predicted power consumption is less than the sum of the peak power and the surplus power Wm, the control unit 102 uses the peak power stored in the power consumption storage unit 121 as the sum of the peak power of the selected server and the surplus power Wm. (Step S227). Next, the control unit 102 submits a job to the server designated by the user first (step S208 in FIG. 5).

  The subsequent steps are the same as those in the first embodiment.

  When the predicted power consumption exceeds the sum of the peak power and the surplus power Wm, the control unit 102 satisfies the customer's request from among the servers 111 and 112 that are operating and connected to the network 101, and has the highest peak power. Select one with a large difference in power consumption. (Step S228).

  The control unit 102 confirms the past power data stored in the power consumption storage unit 121 of the selected server and the current power consumption measured by the power consumption measurement unit 122 (step S229).

  Here, the control unit 102 confirms whether or not the past power data is in the power consumption storage unit 121 (step S230). If there is, the value obtained by adding the past power data to the current power consumption is set as the predicted power consumption (step S230). S231). If the past power data does not exist in the power consumption storage unit 121, the control unit 102 calculates the average of the past power data of all users stored in the power consumption storage unit 121, and uses the average value as the past power of the job input user. The data is set and stored in the power consumption storage unit 121 (step S232). Next, as in the case where the past power data is in the power consumption storage unit 121, the control unit 102 sets the value obtained by adding the past power data to the current power consumption as the predicted power consumption (step S231).

  Next, the control unit 102 adds the peak power stored in the power consumption storage unit 121 of the server selected in step S228 and the marginal power Wm, and compares it with the predicted power consumption (step S233).

  When the predicted power consumption is less than the sum of the peak power and the surplus power Wm, the control unit 102 uses the peak power stored in the power consumption storage unit 121 as the sum of the peak power of the selected server and the surplus power Wm. (Step S227). Next, the control unit 102 submits the job to the server selected in step S228 (step S208 in FIG. 5).

  The subsequent steps are the same as those in the first embodiment.

  The operation of the power control system 200 when the predicted power consumption exceeds the sum of the peak power and the surplus power Wm (No in step S233) will be described with reference to the flowchart shown in FIG.

  First, the control unit 102 reselects the server designated by the user as the job input server first (step S234).

  The control unit 102 waits for completion of one of the jobs being executed (step S235).

  Since the job input user's request could not be satisfied, the power control system 200 reduces the system usage fee for the user by a fixed amount (step S236).

  Thereafter, similarly to step S231 and step S233, the control unit 102 calculates the predicted power consumption (step S237) and compares whether or not the sum of the peak power and the margin power Wm is exceeded (step S238). If exceeded, the control unit 102 waits for completion of one of the jobs being executed (step S239), and again calculates the predicted power consumption (step S237) and compares the peak power with the sum of the marginal power Wm (step S239). S238).

  When the predicted power consumption is lower than the peak power, the control unit 102 updates the peak power stored in the power consumption storage unit 121 with the sum of the peak power of the selected server and the surplus power Wm (step S240). ). Next, the control unit 102 submits a job (step S208 in FIG. 5).

  The subsequent steps are the same as those in the first embodiment.

  Thus, the power control system 200 ends the job assignment operation.

  In the case of this embodiment, if the power control system 200 is left unattended, there is a possibility that the servers that are stopped are powered on and the number of idle servers increases and power consumption increases. For this reason, it is necessary to power off servers that are not being used. An example of the power-off operation of the server in the idling state will be described with reference to the flowchart shown in FIG.

  The control unit 102 searches for an active server from the servers 111 and 112 connected to the network 101 (step S241).

  If there is an active server, the control unit 102 checks whether there is a job that is currently submitted to the server (whether it is not in an idling state) (step S242).

  If there is an input job, the control unit 102 searches the servers 111 and 112 connected to the network 101 for other active servers (step S241).

  If there is no input job, the power management unit 203 stops the server and turns off the power (step S243).

  The control unit 102 adds the peak power of the stopped server evenly to all operating servers connected to the network 101, and outputs and updates the peak power to the power consumption storage unit 121 of each operating server. The power consumption storage unit 121 of each operating server stores the updated peak power (step S244).

  The control unit 102 searches the servers 111 and 112 connected to the network 101 for other servers in operation (step S241). If there is, the same processing is performed (steps S242 to S244).

  When all the servers in operation are confirmed, the process ends.

  Thus, the power control system 200 ends the power-off operation of the idle server. The power-off operation of the server in the idling state needs to be performed at a certain time period, but the system administrator may arbitrarily determine the setting of the time period.

  Next, effects of the second exemplary embodiment of the present invention will be described.

  The power control system according to the present embodiment described above can reduce the job input waiting time exceeding the allowable value.

  This is because the following configuration is included. That is, firstly, in addition to the first embodiment, the control unit 102 confirms the power consumption status of other servers such as the servers 111 and 112 connected to the network 101, and there is an active server that can submit jobs. Submit a job. Secondly, the control unit 102 reduces the peak power of other servers such as the servers 111 and 112 connected to the network 101, starts a stopped server connected to the network 101, and executes job submission. . Thirdly, the control unit 102 executes job submission by decreasing the peak power of other servers such as the servers 111 and 112 connected to the network 101 and increasing the peak power of the active server. Therefore, since the control unit 102 controls job submission not only for the server designated by the user but also for all servers connected to the network 101, it is possible to reduce the excess of the allowable job submission waiting time. Is obtained.

  It should be noted that all the stopped servers are investigated, and the operation of the power control system 200 (No in step S220) when there is no server that can be powered on may be directly transferred to step S228.

  Referring to FIG. 12, first, the control unit 102 selects a server selected by the user as a job input server (step S301). At this time, it is confirmed whether there is already a job waiting for submission on the server selected by the user (step S302), and if there is, the control unit 102 waits until there is no job waiting for submission already existing at the time of server selection (step S302). Step S303). The job matrix control unit 305 controls (sorts) the job matrix so that the margin of the job submission waiting time is in ascending order during standby (an example of the method will be described later).

  When there are no jobs waiting to be submitted at the time of selection, or there are no jobs waiting to be submitted from the beginning at the time of selection, the estimated power consumption and past power data are compared for the server selected by the user, and the job submission waiting time is compared. Until the value exceeds the allowable value according to the priority specified by the user, the job submission is delayed until the predicted power consumption falls below the peak power. The steps so far are the same as steps S102 to S111 of the first embodiment (steps S304 to S313).

  The operation of the power control system 300 when the job submission waiting time exceeds the allowable value designated by the user (Yes in step S313) will be described with reference to the flowchart shown in FIG. Also in this case, similarly to FIG. 3 of the first embodiment and steps S113 to S116, since the request of the job input user cannot be satisfied, the control unit 102 of the power control system 100 determines the system usage fee for the user. Is reduced by a certain amount corresponding to the penalty (step S314).

  Thereafter, similarly to step S104 to step S111, the control unit 102 calculates the predicted power consumption (step S315) and compares whether the peak power is exceeded (step S316). If exceeded, the control unit 102 waits for completion of one of the jobs being executed (step S317), and again calculates the predicted power consumption and compares it with the peak power (steps S315 and S316).

  When the predicted power consumption is lower than the peak power, the control unit 102 inputs a job (step S310) as in the case where the predicted power consumption is lower than the beginning, and the power consumption measurement unit 122 measures an increase in power consumption due to job input (step S310). S311). The control unit 102 updates the past power data and the number of job submissions, and stores them in the power consumption storage unit 121 (step S312).

  An example of a job matrix control (sort) method by the job matrix control unit 305 will be described with reference to FIG.

  First, the job matrix control unit 305 searches for an active server in the network 101 (step S318). If there is no active server in the network 101, the process is terminated. If there is an active server, the number N of jobs waiting for input of the active server is checked to determine whether N is greater than 3 (step S319). Since the first job in the job matrix is a job allocation operation target of the control unit 102, it is not subject to job matrix control (sorting) by the job matrix control unit 305. In other words, when the number N of waiting jobs is 1, there is no job queue control target job, and when the number N of job waiting N is 2, there is a job queue control target job, but there is not more than one, so the job queue is sorted. Does not occur.

  Next, j is defined as a parameter. The initial value of j is set as 0. Also, i is defined as the number of exchanges in the order of jobs in one sort process. The initial value of i is also 0 (step S320).

If j is smaller than N−1 (step S321), let T _L (j) be the allowable value for the jth job submission wait time in the job matrix and T _W (j) be the job submission wait time.
T _L (N−j) −T _W (N−j) <T _L (N−j−1) −T _W (N−j−1)
Is satisfied, the (N−j−1) th job in the job matrix has a smaller margin of job input waiting time than the previous (N−j−1) th job. It is preferable that the job is submitted before the first job. for that reason,
T _L (N−j) −T _W (N−j) <T _L (N−j−1) −T _W (N−j−1)
If this is true (step S323), the job matrix control unit 305 performs a process of replacing the (N−j) th job and the (N−j−1) th job (step S324). Further, the order exchange count i is updated to i + 1 (step S324). If it does not hold, do nothing.

  The job matrix control unit 305 updates the parameter j as j + 1 (step S325), and performs the processing from step S321 to step S325 again.

  These processes are performed when the job queue control unit 305 compares the last job of the job queue with the previous job, and if there is a job with a smaller margin of job submission waiting time at the back of the queue. This is a process of exchanging the order with the previous job.

  If j is greater than or equal to N−1 (step S321), the order exchange process from the last job in the job queue to the second job is completed once. This process is repeated until all jobs are sorted in order of increasing margin of job input waiting time. When the sorting is completed, the job order is not exchanged. Therefore, a case where the order exchange number i is 0 is set as a condition for completion of sorting.

  If the number of order exchanges i is not 0 when one order exchange process is completed (step S326), all jobs may not be sorted in the order in which the margin of the job input waiting time is small. Steps S320 to S326 are performed again.

  When the number of order exchanges i becomes 0 when one order exchange process is completed (step S326), the job matrix control unit 305 sorts the jobs into an order in which the margin of the job submission waiting time in the server is small. Is completed and a search is made as to whether there is another server in the network 101 (step S327). If there is an active server in the network 101, the job matrix control unit 305 performs the same process (steps S319 to S327), and if there is no active server, the process is terminated.

  Thus, the power control system 300 ends the job assignment operation.

  Next, effects of the third exemplary embodiment of the present invention will be described.

  The power control system according to the present embodiment described above can reduce the job input waiting time exceeding the allowable value.

  This is because the following configuration is included. That is, first, the job queue control unit 305 checks the waiting time and allowable value of two waiting jobs in the job waiting queue in addition to the first embodiment. Secondly, when the margin of the job submission waiting time is smaller than the job submission waiting time of the previous job, the job queue control unit 305 repeats the process of switching the order of the job scheduled to be submitted and the previous waiting job, Sort jobs in ascending order of job submission waiting time. Therefore, it is possible to reduce the job submission waiting time exceeding the allowable value.

[Fourth Embodiment]
Next, a fourth 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. 15 is a block diagram showing a configuration of a power control system 400 according to the fourth embodiment of the present invention.

  Referring to FIG. 15, the power control system 400 in the present embodiment further includes a job matrix control unit 305 as compared with that in the second embodiment. Further, compared with that of the third embodiment, a power management unit 203 and an idling state power consumption storage unit 204 are further provided. That is, a power control system in which the system of the second embodiment and the system of the third embodiment are combined.

  Next, the operation of the power control system 400 will be described with reference to the flowcharts shown in FIGS. 16, 17, 18, 19, and 20.

  16, FIG. 17, FIG. 18, FIG. 19, and FIG. 20 are flowcharts showing an overview of job assignment operations in the power control system 400 according to the fourth embodiment.

  Referring to FIG. 16, first, the control unit 102 selects a server selected by the user as a job input server (step S401). At this time, it is confirmed whether there is already a job waiting for submission on the server selected by the user (step S402), and if there is, the control unit 102 waits until there is no job waiting for submission already existing at the time of server selection (step S402). Step S403). The job matrix control unit 305 controls (sorts) the job matrix so that the margin of the job submission waiting time is in ascending order during standby.

  When there are no jobs waiting to be submitted at the time of selection, or there are no jobs waiting to be submitted from the beginning at the time of selection, the estimated power consumption and past power data are compared for the server selected by the user, and the job submission waiting time is compared. Until the value exceeds the allowable value according to the priority specified by the user, the job submission is delayed until the predicted power consumption falls below the peak power. The steps so far are the same as steps S101 to S112 of the first embodiment (steps S404 to S413).

  The operation of the power control system 300 when the job submission waiting time exceeds the allowable value designated by the user (Yes in step S413) will be described with reference to the flowchart shown in FIG.

  Since the job submission waiting time exceeds the allowable value, the power control system 400 needs to investigate a server that can urgently submit the job.

  The control unit 102 monitors the operating state of each server, for example, by monitoring the power supply state in the power management unit 203, and there are other servers in operation other than the server (for example, the server 111) scheduled to submit jobs. Whether or not (step S414).

  When there is an active server, the control unit 102 checks whether or not the server (for example, the server 112) has a performance capable of submitting a job (step S415).

  If there is a performance that can be submitted, the control unit 102 checks whether there is a job submission waiting state in the server (112) (step S416).

  When there is no job submission waiting, the control unit 102 submits a job at the server (step S410 in FIG. 16).

  The subsequent steps are the same as steps S108 to S110 of the first embodiment (steps S410 to S412).

  When there is a job submission wait or when the performance is not sufficient to submit the job, the control unit 102 checks whether there is any other active server, and in the same case, investigates (steps S414 to S416).

  The control unit 102 examines all operating servers, and describes the operation of the power control system 400 when there is no server that can submit a job (No in step S414) with reference to the flowchart shown in FIG.

  First, the control unit 102 sets Wm as the overall surplus power of each of the servers 111 and 112 connected to the network 101. Here, initialization is performed with Wm = 0 (step S417).

  The control unit 102 checks whether or not the gap between the peak power of the server and the current power consumption exceeds a threshold, for example, 100 W (step S418).

  If it exceeds, the control unit 102 updates the peak power stored in the power consumption storage unit 121 of the server by reducing it by 50 W (step S419). The decrease in peak power must be smaller than the above threshold. Next, the control unit 102 adds the power 50W corresponding to the reduced peak power to the surplus power Wm. Specifically, Wm = Wm + 50 is added (step S420).

  The control unit 102 checks whether there are other active servers other than the server that is scheduled to submit the job (step S421). When there is an operating server, the control unit 102 repeats the above processing for the operating server (steps S418 to S421).

  Next, the control unit 102 checks whether there is a stopped server among the servers 111 and 112 connected to the network 101 (step S422).

  When there is a stopped server, the control unit 102 checks the idling state power consumption of the server stored in the idling state power consumption storage unit 204 (step S423). When the surplus power Wm is larger than the idle state power consumption of the server + 100 W (100 W is a threshold value in step S418) (step S424), the power management unit 203 turns on the power of the server and starts it (step S425). The control unit 102 submits a job at the activated server (step S410 in FIG. 16).

  The subsequent steps are the same as steps S108 to S110 of the first embodiment (steps S410 to S412).

  If the surplus power Wm is smaller than the idle state power consumption of the server +100 W, the power is not turned on and the control unit 102 repeats the above processing until it determines that there is no other stopped server (steps S422 to S424). .

  The operation of the power control system 200 (No in step S422) when all the stopped servers are investigated and no server can be turned on will be described with reference to the flowchart shown in FIG.

  Referring to FIG. 19, first, the control unit 102 first selects a server designated by the user as a job input server (step S426). At this time, it is confirmed whether or not there is already a job waiting for submission on the server selected by the user (step S427), and if there is, the control unit 102 waits until there is no job waiting for submission already existing at the time of server selection (step S427). Step S428). The job matrix control unit 305 controls (sorts) the job matrix so that the margin of the job submission waiting time is in ascending order during standby (see the third embodiment for an example of a method).

  When there is no job waiting to be submitted already at the time of selection, or when there is no job waiting to be submitted from the beginning at the time of selection, the power consumption is compared with the current power consumption measured by the power consumption measuring unit 122 for the server selected by the user. A value obtained by adding the past power data stored in the storage unit 121 (it is clear that the past power data of the server first designated by the user in steps S405 and S407 exists) is used as the predicted power consumption data. Occurs (step S429). The predicted power consumption data of the server designated by the user first has already been calculated in step S406. However, since there is a possibility that the current power consumption has changed, it is calculated again in this step.

  Next, the control unit 102 adds the peak power stored in the power consumption storage unit 121 of the server first designated by the user and the margin power Wm, and compares it with the predicted power consumption (step S430). When the predicted power consumption is less than the sum of the peak power and the surplus power Wm, the control unit 102 uses the peak power stored in the power consumption storage unit 121 as the sum of the peak power of the selected server and the surplus power Wm. (Step S431). Next, the control unit 102 submits a job to the server designated by the user first (step S410 in FIG. 16).

  The subsequent steps are the same as steps S108 to S110 of the first embodiment (steps S410 to S412).

  When the predicted power consumption exceeds the sum of the peak power and the surplus power Wm, the control unit 102 determines that the difference between the peak power and the current power consumption is the largest among the operating servers 111 and 112 connected to the network 101. Choose a larger one. (Step S432). At this time, it is confirmed whether or not there is already a job waiting to be submitted in the selected server (step S433), and if there is, the control unit 102 waits until there is no job waiting to be submitted already at the time of server selection (step S434). ). The job matrix control unit 305 controls (sorts) the job matrix so that the margin of the job submission waiting time is in ascending order during standby (see the third embodiment for an example of a method).

  When there is no job waiting to be submitted that has already been selected at the time of selection, or when there is no job waiting to be submitted from the beginning at the time of selection, the past power data and power consumption measurement stored in the power consumption storage unit 121 for the selected server. The current power consumption measured by the unit 122 is confirmed (step S435).

  Here, the control unit 102 checks whether or not the past power data is in the power consumption storage unit 121 (step S436). If there is, the value obtained by adding the past power data to the current power consumption is set as the predicted power consumption (step S436). S438). If the past power data does not exist in the power consumption storage unit 121, the control unit 102 calculates the average of the past power data of all users stored in the power consumption storage unit 121, and uses the average value as the past power of the job input user. The data is set and stored in the power consumption storage unit 121 (step S437). Next, as in the case where the past power data is in the power consumption storage unit 121, the control unit 102 sets the value obtained by adding the past power data to the current power consumption as the predicted power consumption (step S438).

  Next, the control unit 102 adds the peak power stored in the power consumption storage unit 121 of the server selected in step S432 and the marginal power Wm, and compares it with the predicted power consumption (step S439).

  When the predicted power consumption is less than the sum of the peak power and the surplus power Wm, the control unit 102 uses the peak power stored in the power consumption storage unit 121 as the sum of the peak power of the selected server and the surplus power Wm. (Step S431). Next, the control unit 102 submits a job to the server selected in step S432 (step S410 in FIG. 16).

  The subsequent steps are the same as steps S108 to S110 of the first embodiment (steps S410 to S412).

  The operation of the power control system 400 when the predicted power consumption exceeds the sum of the peak power and the surplus power Wm (No in step S439) will be described with reference to the flowchart shown in FIG.

  First, the control unit 102 reselects a server designated by the user as a job input server first (step S440).

  The control unit 102 waits for completion of one of the jobs being executed (step S441).

  Since the job input user's request could not be satisfied, the power control system 400 reduces the system usage fee for the user by a fixed amount (step S442).

  Thereafter, similarly to step S438 and step S439, the control unit 102 calculates the predicted power consumption (step S443), and compares whether or not the sum of the peak power and the margin power Wm is exceeded (step S444). If exceeded, the control unit 102 waits for completion of one of the jobs being executed (step S445), and again calculates the predicted power consumption (step S443) and compares the peak power with the sum of the marginal power Wm (step S445). S444).

  When the predicted power consumption is lower than the peak power, the control unit 102 updates the peak power stored in the power consumption storage unit 121 with the sum of the peak power of the selected server and the margin power Wm (step S446). ). Next, the control unit 102 first submits a job to the server designated by the user (step S410 in FIG. 16).

  The subsequent steps are the same as steps S108 to S110 of the first embodiment (steps S410 to S412).

  Thus, the power control system 400 ends the job assignment operation.

  In the case of this embodiment, as in the second embodiment, if the power control system 400 is left unattended, the number of idle servers increases. For this reason, it is necessary to power off servers that are not being used. An outline of the power-off operation of the server in the idling state is shown in FIG.

  The control unit 102 searches for an active server in an idle state from the servers 111 and 112 connected to the network 101, and when found, the power management unit 203 stops the server and turns off the power. In addition, the control unit 102 updates the peak power by equally adding the peak power of the stopped server to the peak power of all the active servers connected to the network 101 (steps S236 to S239).

  When all the servers in operation are confirmed, the process ends.

  As described above, the power control system 400 ends the power-off operation of the idle server.

  Next, the effect of the 4th Embodiment of this invention is demonstrated.

  The power control system in the present embodiment described above can realize control that does not exceed the upper limit value of power more strongly than the first embodiment, the second embodiment, and the third embodiment even during a power consumption peak.

  This is because the following configuration is included. That is, first, when the predicted power exceeds the peak power, the control unit 102 performs control not to submit a job until the predicted power falls. Second, the control unit 102 controls job submission for all servers connected to the network 101 as well as the server designated for submission by the user. Thirdly, the control unit 102 controls the job waiting queue of the server, and optimizes the order of submission so that the margin of job submission waiting time is in ascending order. Therefore, the effect that the control which does not exceed the upper limit value of electric power can be realized more strongly than the first embodiment, the second embodiment, and the third embodiment at the time of the power consumption peak.
