Conventionally, as a technique for effectively using power, a power saving technique for reducing power consumption and a technique for effectively using surplus power are known.

  For example, as a power saving technique for reducing the power consumption of the information processing apparatus, a technique of adjusting the driving frequency or the driving voltage according to the operating state of the information processing apparatus is used. As an example, SpeedStep (registered trademark) of Intel Corporation, LongRun (registered trademark) of Trans Meta Corporation, or a technology for collectively controlling a plurality of information processing apparatuses on a network (see Patent Document 1) is used. Yes.

  Further, as a technique for effectively using surplus power, a technique for leveling power consumption has been proposed. For example, a technique for preferentially using a precharged battery when power consumption is concentrated in a predetermined area is proposed as a technique for leveling the bias of power consumption according to time zones (see Patent Document 2).

  FIG. 2 shows a block diagram of the calculation requesting device 20. The calculation requesting device 20 includes a power processing index information acquisition unit 200, a stability information acquisition unit 205, a computer environment database 210, a partial calculation request unit 215, a request history information storage unit 220, and a power consumption index information generation unit. 225, power consumption index information storage means 230, calculation content analysis means 240, condition information acquisition means 250, area information acquisition means 260, power charge information generation means 270, selection means 275, and processing result output means. 280.

Further, the power processing index information acquisition unit 200 acquires the power processing comprehensive information from the upper layer management devices 50-1 to 50 -L and stores it in the computer environment database 210.

  The stability information acquisition unit 205 acquires, for each of the calculation processing devices 30-1 to 30 -N, stability information indicating the stability of the power supplied to the calculation processing device, and stores it in the computer environment database 210. For example, the stability information acquisition unit 205 receives, from the region information acquisition unit 260, regional information indicating in which of the plurality of predetermined regions each calculation processing device is provided, and is supplied to the regional information. Information indicating the stability of electricity is received from the upper level management devices 50-1 to 50 -N as stability information and stored in the computer environment database 210.

  Instead of this, the power processing index information acquisition unit 200 and the stability information acquisition unit 205 receive power processing index information and information from each of the calculation processing devices 30-1 to 30-N without going through the lower layer management device and the upper layer management device. Each of the stability information may be acquired.

  The request history information storage unit 220 stores information in which information for identifying a set of calculation processing devices that have performed the calculation processing is associated with the type of calculation processing that has already been performed by the calculation requesting device 20. For example, the type of calculation process is information indicating the nature of the calculation performed by the calculation process, and is determined by an API of an operating system that is called when the calculation process is executed.

  When the partial calculation request unit 215 obtains the calculation process 700 to be executed from the user, the partial calculation request unit 215 obtains information for identifying a set of calculation processing devices associated with the type of the calculation process 700 based on the type of the calculation process 700. The request history information storage means 220 is searched. If the search is successful, the partial calculation requesting unit 215 causes the searched set of calculation processing devices to perform the calculation process 700. If the search is not successful, the partial calculation request unit 215 sends a message to that effect to the power consumption index information generation unit 225.

  Then, the partial calculation request unit 215 transmits each of the plurality of partial calculations to the calculation processing device so that the selection processing unit 275 causes the calculation processing device selected in association with the partial calculation to execute. Instead, the partial calculation requesting unit 215 transmits each of the plurality of partial calculations to each of the calculation processing devices via the lower layer management devices 40-1 to M and the upper layer management devices 50-1 to L. May be.

  Further, the partial calculation requesting unit 215 sends, to each of the plurality of partial calculations, information for identifying a calculation processing device that executes the partial calculation, to the processing result output unit 280. Further, the partial calculation request unit 215 stores the types of calculation processes constituted by a plurality of partial calculations in the request history information storage unit 220 in association with a set of calculation processing devices that execute a plurality of partial calculations.

  The power consumption index information storage unit 230 associates the type of partial calculation with power consumption index information indicating the amount of power required for the partial calculation compared with the case where another partial calculation is processed in the same calculation processing device. Store.

  When the partial calculation requesting unit 215 cannot search the request history information storage unit 220 for information for identifying a set of calculation processing devices, the power consumption index information generating unit 225 executes the calculation processing 700 acquired from the user by a plurality of calculation processes 700. Divide into partial calculations. For each of the partial calculations, when the type of the partial calculation is stored in the power consumption index information storage unit 230, the power consumption index information generation unit 225 uses the power consumption associated with the type of the partial calculation. The index information is selected from the power consumption index information storage unit 230.

  On the other hand, when the type of the partial calculation is not stored in the power consumption index information storage unit 230, the power consumption index information generation unit 225 sends the partial calculation to the calculation content analysis unit 240. Then, the power consumption index information generation unit 225 generates power consumption index information based on the analysis result received from the calculation content analysis unit 240 and sends it to the selection unit 275. Further, the power consumption index information generating unit 225 stores the type of partial calculation in the power consumption index information storage unit 230 in association with the generated power consumption index.

  The calculation content analysis unit 240 analyzes the processing content of the partial calculation received from the power consumption index information generation unit 225 and returns it to the power consumption index information generation unit 225. Further, the calculation content analysis unit 240 generates critical path information obtained by analyzing whether or not the partial calculation is included in the critical path of the calculation process, and sends the critical path information to the selection unit 275. Here, the critical path refers to a group of partial calculations having the longest time required for the calculation among a plurality of partial calculations whose execution order is fixed and cannot be executed in parallel.

  The condition information acquisition unit 250 includes power amount condition information that should be satisfied when the calculation processing devices 30-1 to 30-N execute a plurality of partial calculations, and the calculation processing devices 30-1 to 30-N include a plurality of portions. Stability condition information indicating the condition of the stability of electricity received when the calculation is executed is acquired from the user and sent to the selection means 275.

  The area information acquisition unit 260 receives area information indicating which of the plurality of predetermined areas each of the calculation processing apparatuses 30-1 to 30-N is provided from the upper layer management apparatuses 50-1 to 50-N. The information is acquired and sent to the stability information acquisition unit 205, the power rate information generation unit 270, and the selection unit 275.

  The power charge information generating unit 270 is configured to calculate, for each of the calculation processing devices 30-1 to 30 -N, the power charge information indicating the power charge per power consumption of the calculation processing device from the regional information acquisition unit 260. And is sent to the selection means 275.

  The selection unit 275 associates each of the plurality of partial calculations with a calculation processing device that satisfies the power amount condition information and the stability condition information when executing the partial calculation among the calculation processing devices 30-1 to 30-N. Selection is made based on the power processing index information, stability information, power consumption index information, critical path information, area information, and power charge information, and the selection result is sent to the partial calculation request means 215.

More specifically, the selection unit 275 uses the power processing index information and the power processing general information managed by the lower layer management devices 40-1 to M and the upper layer management devices 50-1 to L according to the following procedure. A computing device may be selected. First, the selection unit 275 selects an upper layer management device, for example, the upper layer management device 50-1, in which any of the power processing comprehensive information to be managed satisfies the power amount condition information and the stability condition information. And the selection means 275 is a lower hierarchy management apparatus in which any of the power processing index information to be managed satisfies the power amount condition information and the stability condition information among the lower hierarchy management apparatuses managed by the upper hierarchy management apparatus 50-1. For example, the lower layer management apparatus 40-1 is selected. Further, the selection unit 275 selects a calculation processing device that satisfies the power amount condition information and the stability condition information, for example, the calculation processing device 30-1 among the calculation processing devices managed by the lower layer management device 40-1. .
Thereby, even if it is a case where there are a huge number of calculation processing devices 30-1 to 30-N, it is possible to efficiently search for an appropriate calculation processing device.

  The processing result output means 280 receives from the partial calculation request means 215 information for identifying a calculation processing device that executes a plurality of partial calculations. Then, the processing result output means 280 outputs a set of partial calculation results received from these calculation processing devices to the user as a result of the calculation processing 700. In addition to this, the processing result output means 280 may output the result of further calculation using the received set of partial calculation results as the result of the calculation processing 700.

  Further, the processing result output means 280 associates the actual power consumption information indicating the amount of power actually consumed when each partial calculation is processed with the information for identifying the calculation processing device that has executed the partial calculation. Are acquired from the calculation processing devices 30-1 to 30 -N and sent to the power processing index information acquisition means 200. In addition, the processing result output unit 280 may output the actual power consumption information to the user in association with information for identifying the calculation processing device. In this case, the user can know the total amount of power used in a predetermined area, for example. As a result, the user can determine whether or not the content of the contract with the electric power company is appropriate as compared with the current total amount of power, and can change the contract as necessary.

  FIG. 3 is a block diagram of the calculation processing device 30-1. The calculation processing device 30-1 includes a partial calculation processing unit 300, a processing result transmission unit 310, an actual consumption transmission unit 320, and a partial calculation reassignment unit 330. Since each of the calculation processing devices 30-2 to 30-N has substantially the same configuration as the calculation processing device 30-1, only the differences will be described.

  The partial calculation processing unit 300 processes the partial calculation requested from the calculation requesting device 20 and sends the processing result to the processing result transmission unit 310. In response to this, the processing result transmission unit 310 transmits the processing result of the partial calculation to the calculation requesting device 20. Further, the actual consumption amount transmitting unit 320 generates power actual consumption amount information indicating the amount of power consumed when the partial calculation processing unit 300 processes the partial calculation by analyzing the processing content of the partial calculation processing unit 300. Then, it is transmitted to the calculation requesting device 20 in association with the information for identifying the partial calculation.

  An example of processing for generating actual power consumption information is shown below. First, the actual consumption amount transmitting unit 320 measures the power consumption amount of the calculation processing device 30-1 in the period in which the partial calculation is executed by a predetermined program for measuring the power consumption amount. Then, the actual consumption transmission means 320 refers to the statistical information of the operating system, and thereby the ratio of the time when the CPU is used by the partial calculation to the time when the CPU is used by the processing of the entire calculation processing device 30-1. Is identified. As a result, the actual consumption transmission means 320 can estimate the power consumption used by the partial calculation and generate it as the actual power consumption information.

  Moreover, the said measuring method about electric power consumption is an example, You may use another method. For example, the actual consumption transmission means 320 may generate the actual power consumption information using an API defined in the operating system, or generate the actual power consumption information using a system call defined in the BIOS. May be. Further, each of the calculation processing devices 30-2 to 30-N may generate the actual power consumption information by a method different from that of the calculation processing device 30-1.

  In response to the notification from the lower layer management apparatus 40-1, the partial calculation reassignment unit 330 determines in advance the total power consumption in the area where the calculation processing apparatus 30-1 is provided among the maximum suppliable power in the area. It is determined whether or not the specified standard ratio has been reached. When the partial calculation reassignment unit 330 determines that the total power consumption of the area has reached the reference ratio, the partial calculation processing unit 300 causes the partial calculation processing unit 300 to stop the partial calculation processing, and the partial calculation processing unit 300 processes the partial calculation. Is obtained from the partial calculation processing means 300. Then, the partial calculation reassignment unit 330 executes the partial calculation in another calculation processing device provided in a region different from the region, for example, the calculation processing device 30-N. 1 to send. In response to this, the lower hierarchy management device 40-1 transmits the partial calculation to the calculation processing device 30-N via the upper hierarchy management device 50-1 and the lower hierarchy management device 40-2.

  As described above, as illustrated in FIGS. 1 to 3, the distributed computing system 10 allows each of the computing devices that execute each of the plurality of partial calculations constituting the predetermined calculation process to be performed per predetermined calculation processing amount. Selection is made so as to satisfy the power processing index information indicating the power consumption and the stability information indicating the stability of the power supplied to the calculation processing device. Thereby, while satisfy | filling the conditions of power consumption, a calculation process can be performed at high speed and highly efficient.

  FIG. 4 shows an operation flow in which the distributed computing system 10 executes calculation processing. The power processing index information acquisition unit 200 acquires power processing index information for each of the calculation processing devices 30-1 to 30-N (S400). For example, the power processing index information acquisition unit 200 uses the power consumption per predetermined processing amount for at least one of the CPU, the hard disk drive, and the input / output device of the calculation processing apparatus as the power processing index information of each calculation processing apparatus. Get the performance information shown.

  Specifically, the power processing index information acquisition unit 200 may acquire information indicating the thermal design power consumption (TDP: Thermal Design Power) of the CPU and the type of CPU as performance information. Thereby, the calculation request | requirement apparatus 20 can estimate the power consumption per CPU 1 clock as power process parameter | index information.

  For example, in the Pentium (registered trademark) 4 processor (Northwood) of Intel Corporation, a plurality of types of processors having different operating frequencies have different TDPs. As an example, in a processor operating at 3.0 Ghz, the TDP is 81.9 W, and in a processor operating at 2.4 Ghz, the TDP is 57.8 W. Therefore, in the 3.0 Ghz operation processor, the power consumption per 1 Ghz is 27.3 W, and in the 2.4 Ghz operation processor, the power consumption per 1 Ghz is 24.1 W. As described above, the power processing index information acquisition unit 200 acquires the CPU TDP and type set as the power processing index information, so that the calculation requesting device 20 can estimate the power consumption per clock.

  In addition, the power processing index information acquisition unit 200 uses the power consumption of the calculation processing apparatus and the calculation processing apparatus when the calculation processing apparatuses 30-1 to 30-N perform a predetermined amount of calculation as the power processing index information. You may acquire the sum total of the power consumption of the network apparatus to which is connected. That is, the power processing index information is not limited to the power consumption of only the calculation processing device, but is the power consumption in a series of processes in which the calculation processing device performs the calculation requested from the calculation requesting device 20 and transmits the calculation result.

  The stability information acquisition unit 205 acquires stability information for each of the calculation processing devices 30-1 to 30-N (S410). For example, the stability information acquisition unit 205 acquires a value obtained by multiplying the average number of instantaneous interruption occurrences per unit time by the average instantaneous interruption time from the upper hierarchy management devices 50-1 to 50 -N as the stability information. Further, the stability information acquisition unit 205 stabilizes information indicating the power stability in the area where each of the calculation processing devices 30-1 to 30 -N is provided based on the area information acquired from the area information acquisition unit 260. It may be acquired as sex information.

  Furthermore, the stability information acquisition unit 205 may acquire information indicating whether or not the calculation processing device is managed by an uninterruptible power supply using a battery or a generator as stability information in each calculation processing device. . In this case, the selection means 275 is a calculation processing device with high power stability compared to a calculation processing device managed by the uninterruptible power supply device compared to a calculation processing device not managed by the uninterruptible power supply device. Judgment can be made.

  When the partial calculation requesting unit 215 obtains the calculation process 700 to be executed from the user (S420), the partial calculation requesting unit 215 identifies a set of calculation processing devices associated with the type of the calculation process 700 based on the type of the calculation process 700. Information to be searched is retrieved from the request history information storage means 220 (S430).

  When the search is successful, that is, when the type of the calculation processing 700 is a type that has already been processed by the calculation requesting device 20 (S440: YES), the partial calculation requesting unit 215 determines that the searched calculation processing device The set is subjected to the calculation process 700 (S450), and the process is terminated. As a result, the calculation requesting apparatus 20 can efficiently operate by omitting the process of selecting a calculation processing apparatus on which partial calculation is to be performed when repeatedly performing the same type of calculation processing. For example, when a plurality of calculation processes in which only some of the parameters are different from each other are repeated, for example, when performing Monte Carlo simulation, it is efficient.

  When the search cannot be performed, that is, when the type of the calculation process 700 is a type that has not yet been processed by the calculation requesting device 20 (S440: NO), the power consumption index information generation unit 225 executes the calculation process 700. Dividing into a plurality of partial calculations (S460). Subsequently, the calculation requesting apparatus 20 executes the following processing for each of the plurality of partial calculations (S470).

When the partial calculation type is stored in the power consumption index information storage unit 230 (S480: YES), the power consumption index information generation unit 225 stores the consumption stored in association with the partial calculation type. The power index information is acquired from the power consumption index information storage unit 230 (S490). On the other hand, the power consumption index information generation means 225 generates power consumption index information when the partial calculation type is not stored in the power consumption index information storage means 230 (S480: NO) (S485). Details will be described later.
The calculation requesting device 20 executes the above processing for each of the plurality of partial calculations (S495).

  FIG. 5 shows an operation flow subsequent to FIG. 4 in the distributed computing system 10. The condition information acquisition unit 250 includes power amount condition information that should be satisfied when the calculation processing devices 30-1 to 30-N execute a plurality of partial calculations, and the calculation processing devices 30-1 to 30-N include a plurality of portions. Stability condition information indicating the condition of the stability of electricity received when the calculation is executed is acquired from the user (S500).

  For example, the condition information acquisition unit 250 acquires a power upper limit value that defines an upper limit of power consumed per unit time in a plurality of calculation processing devices provided in a predetermined region as the power amount condition information. Instead of this, the condition information acquisition unit 250 may acquire the upper limit value of the total power consumption consumed from the start to the end of the calculation process as the power amount condition information. In addition, the condition information acquisition unit 250 may acquire the power amount condition information that sets the power consumption to a predetermined amount or less under the condition that the execution time of the critical path of the calculation process is within a predetermined time, You may acquire the electric energy condition information made into below predetermined.

  The area information acquisition unit 260 acquires area information indicating which of the plurality of predetermined areas each of the calculation processing devices 30-1 to 30-N is provided (S510). For example, the regional information acquisition unit 260 includes, as regional information in each of the calculation processing devices 30-1 to 30-N, information indicating the country in which the calculation processing device is provided, and a power company that supplies power to the calculation processing device. Information indicating a network domain to which the calculation processing device belongs, information indicating a building in which the calculation processing device is provided, or information indicating a floor or a room in which the calculation processing device is provided may be acquired. .

  The power charge information generation unit 270 generates power charge information indicating the power charge per power consumption for each of the calculation processing devices 30-1 to 30-N based on the regional information (S520). For example, based on the time zone in which the calculation process is performed and the time zone of the region determined by the region information, the power rate information generation unit 270 determines whether the time zone in which the calculation process is performed is daytime or nighttime in the region. The electricity bill information is generated in association with each of the calculation processing devices 30-1 to 30-N. More specifically, the power rate information generation unit 270 may acquire the current time acquired from the NTP server as a time zone during which the calculation process is performed. In addition, the power rate information generation unit 270 may determine a time zone of a region determined by the region information based on a database in which a time difference is recorded in association with each country or region.

  The selection unit 275 associates each of the plurality of partial calculations with a calculation processing device that satisfies the power amount condition information and the stability condition information when executing the partial calculation among the calculation processing devices 30-1 to 30-N. A selection is made based on power processing index information, stability information, power consumption index information, area information, and power rate information (S525). An example of the selection method is shown below.

  When the condition information acquisition unit 250 acquires the power upper limit value in a plurality of calculation processing devices provided in a predetermined region as the power amount condition information, the selection unit 275 indicates that the plurality of calculation processing devices in the predetermined region When the power consumed per unit time by processing a plurality of partial calculations is less than or equal to the power upper limit value acquired by the condition information acquisition unit 250 (for example, a value specified by wattage), the plurality of partial calculations are performed. A plurality of calculation processing devices in the predetermined area may be selected in association with each of the above.

  In this case, preferably, the condition information acquisition unit 250 sets a value obtained by subtracting a predetermined amount from the power upper limit value instead of the power upper limit value as a power amount that can be consumed in the predetermined area. That is, when the power consumed per unit time is equal to or less than a value obtained by subtracting a predetermined amount from the power upper limit value, the selection unit 275 preferably selects a plurality of calculation processing devices in the predetermined area. Thereby, even if the power processing index information or the power consumption index information has an error compared with the actual power consumption, it is possible to prevent the actual power consumption from exceeding the power upper limit value.

  As another example, the selection unit 275 is a calculation processing device that executes each of a plurality of partial calculations. In the area where the calculation processing device is provided, the calculation processing in which the partial calculation request unit 215 requests partial calculation is nighttime. A device is selected in preference to a calculation processing device whose time is daytime. This makes it possible to effectively use the surplus power at night and to save the electricity bill in the distributed computing system 10 as a whole. Here, the night refers to a time zone in which a night electricity charge is applied, which is determined by a company that supplies power. In addition, daytime means a time zone in which daytime electricity charges are applied. In addition, the distinction between nighttime and daytime is an example, and the selection unit 275 is configured so that the calculation processing device in the time zone in which power consumption in the predetermined area is smaller than the calculation processing device in the time zone in which power consumption is higher. You should select with priority.

  As yet another example, the selection unit 275 compares the calculation processing device that satisfies the power amount condition information and the stability condition information with a calculation processing device that selects and matches the partial calculation that is not included in the critical path. A calculation processing device having a larger power consumption and a faster processing speed indicated by the power processing index information is selected in association with the partial calculation included in the critical path of the calculation processing. As a result, the calculation in the critical path can be quickly processed even when the power consumption is large, so that the processing speed can be increased while satisfying the power amount condition information and the stability condition information.

  In addition, the selecting unit 275 associates the stability information with the partial calculation included in the critical path of the calculation processing device, as compared with the calculation processing device selected in association with the partial calculation not included in the critical path. Select a computing device that exhibits greater stability. Thereby, it is possible to prevent the completion of the calculation process from being delayed due to the interruption or recalculation of the calculation due to an instantaneous power interruption or the like.

  Subsequently, the partial calculation request unit 215 transmits an instruction to start execution of the partial calculation for each of the plurality of partial calculations to the calculation processing device selected by the selection unit 275 in association with the partial calculation ( S530). For example, the partial calculation request unit 215 transmits the partial calculation to the calculation processing device 30-1 selected in association with the partial calculation. Instead, the partial calculation request unit 215 may transmit the partial calculation to the upper hierarchy management device selected by the selection unit 275, for example, the upper hierarchy management device 50-1. In this case, the upper hierarchy management apparatus 50-1 transfers the partial calculation to the lower hierarchy management apparatus 40-1 that manages the calculation processing apparatus that executes the partial calculation. Furthermore, the lower layer management apparatus 40-1 transfers the partial calculation to the selected calculation processing apparatus. That is, the partial calculation request unit 215 may transmit the partial calculation to the calculation processing device via the upper hierarchy management device and the lower hierarchy management device.

  Here, when a plurality of calculation processing devices in the same region are selected as calculation processing devices for processing a plurality of partial calculations, preferably, the partial calculation requesting means 215 is assigned to one calculation processing device in the same region. The timing for starting execution of each of the plurality of partial calculations is adjusted so that the time at which the partial calculation is started and the time at which the other calculation processing device in the region starts the partial calculation are different. As a result, when the power consumption becomes higher at the start of the calculation than after the start of the calculation, for example, even when a hard disk drive or the like is driven at the start of the calculation, the instantaneous maximum power consumption in the same region can be reduced. it can.

  More preferably, the partial calculation requesting unit 215 starts the partial calculation that requires a longer processing time earlier than the partial calculation that requires a shorter processing time. Thereby, the time required from the start of calculation to the end of each of the plurality of partial calculations can be shortened.

  Subsequently, the partial calculation requesting unit 215 stores the types of calculation processing constituted by a plurality of partial calculations in the request history information storage unit 220 in association with a set of calculation processing devices that execute the plurality of partial calculations ( S533).

  When receiving an instruction to start execution of partial calculation (S535: YES), the partial calculation processing means 300 executes partial calculation (S540). The partial calculation reassignment unit 330 determines whether or not the total power consumption of the area where the calculation processing device 30-1 is provided has reached a predetermined reference ratio among the maximum suppliable power in the area ( S545).

  When the partial calculation reassignment unit 330 determines that the total power consumption of the area has reached the reference rate (S545: YES), the partial calculation processing unit 300 causes the partial calculation processing unit 300 to stop the partial calculation processing, and the partial calculation processing unit 300 The partial calculation to be processed in step S3 is acquired from the partial calculation processing unit 300 and transmitted to another calculation processing device (S550). Thereby, the calculation processing apparatus 30-1 can prevent the concentration of power consumption in a predetermined area autonomously regardless of the processing of the calculation requesting apparatus 20.

  When it is determined that the total power consumption in the area has not reached the reference ratio (S545: NO), it is determined whether or not the partial calculation is completed (S555). When the partial calculation is not completed (S555: NO), the calculation processing device 30-1 returns the process to S540 and continues the partial calculation process.

  On the other hand, when the partial calculation is completed (S555: YES), the processing result transmitting unit 310 transmits the processing result of the partial calculation to the calculation requesting apparatus 20 (S560). Further, the actual consumption amount transmitting unit 320 generates power actual consumption amount information indicating the amount of power consumed when the partial calculation processing unit 300 processes the partial calculation by analyzing the processing content of the partial calculation processing unit 300. Then, it is transmitted to the calculation requesting apparatus 20 in association with the information for identifying the partial calculation (S575).

  When the processing result output unit 280 receives processing results for each of the plurality of partial calculations from the calculation processing devices 30-1 to 30 -N (S 565: YES), the processing result output unit 280 As a result, it outputs to the user (S570). In addition, the power processing index information acquisition unit 200 uses the actual power consumption information indicating the amount of power actually consumed when each partial calculation is processed as information for identifying the calculation processing device that has executed the partial calculation. Correspondingly, it is acquired from the calculation processing devices 30-1 to 30-N via the processing result output means 280 (S580). Then, the power processing index information acquisition unit 200 stores the received actual power consumption as power processing index information in the computer environment database 210 (S590).

  FIG. 6 shows the details of the operation flow in S485. The calculation content analysis means 240 analyzes the number of instructions included in each partial calculation for each of the plurality of partial calculations (S600). For example, the calculation content analysis unit 240 may analyze the number of execution steps in the execution path predicted to be executed in the partial calculation as the number of instructions, or may analyze the number of instructions in the entire partial calculation. . Moreover, the calculation content analysis means 240 may analyze the number of instructions using the induction variable in the loop processing.

  In addition, the calculation content analysis unit 240 analyzes the number of times the input / output device is accessed in the partial calculation processing for each of the plurality of partial calculations (S610). For example, the calculation content analysis unit 240 may analyze the number of accesses based on the number of API calls used to access the input / output device.

  Furthermore, the calculation content analysis means 240 analyzes the size of the transfer data transferred by the input / output device in the partial calculation process for each of the partial calculations (S620). For example, the calculation content analysis means 240 may analyze the size of transfer data based on the value of an API argument used to access the input / output device.

  In addition, the calculation content analysis unit 240 analyzes, for each of the plurality of partial calculations, whether or not the partial calculation is included in the critical path in the calculation process (S630). Further, the calculation content analysis means 240 executes, for each of the plurality of partial calculations, a benchmark program that is another process that is the same type of process as the partial calculation and has a shorter processing time than the partial calculation ( S640).

  Subsequently, the power consumption index information generating unit 225 generates power consumption index information by the following processing based on the analysis result (S650). For example, the power consumption index information generating unit 225 compares each partial calculation with the other partial calculations when the partial calculation has a larger number of instructions than the other partial calculations. Power consumption index information indicating that the power consumption is large is generated.

  In addition, the power consumption index information generating unit 225 compares each partial calculation with the other partial calculations when the number of accesses is larger than that of the other partial calculations. To generate a power consumption index indicating that the power consumption is large. In addition, the power consumption index information generation unit 225 compares each partial calculation with another partial calculation when the size of the transfer data is larger than that of the other partial calculation. Then, a power consumption index indicating that the power consumption is large is generated.

  For example, the power consumption index information generating unit 225 includes, for each of the plurality of partial calculations, the amount of CPU computation required for the partial calculation processing compared to the case where another partial calculation is processed in the same calculation processing device, the hard disk drive Processing content information indicating at least one of the access amount to the device and the usage amount of the input / output device may be generated as power consumption index information. The power consumption index information generating unit 225 may generate power consumption index information based on the amount of power consumed as a result of executing the benchmark program.

  Subsequently, the power consumption index information generation unit 225 stores the type of partial calculation in the power consumption index information storage unit 230 in association with the generated power consumption index (S660).

  FIG. 7 shows details of the calculation process 700. The calculation process 700 includes application 1, application 2, application 3, application 4, application 5, application 6, and application 7, each of which is an example of partial calculation. A solid line arrow in this figure indicates a calling relationship between applications. For example, during processing by the application 1, the applications 2 to 4 are sequentially called and executed. Further, the power consumption index information generating unit 225 generates each of the power consumption index information A1 to A7 in association with each of the applications 1 to 7.

  Further, each of the applications includes a plurality of jobs, each of which is an example of partial calculation. For example, the application 4 includes job 1, job 2, job 3, job 4, job 5, and job 6. As in the case of the application, job 2 and job 3 are sequentially called and executed during processing by job 1. The power consumption index information generating unit 225 generates each of the power consumption index information J1 to J6 in association with each of the jobs 1 to 6.

  As described above, the calculation processing 700 is classified into a plurality of partial calculations for each unit that is called and executed, and the calculation requesting device 20 assigns each of these partial calculations to the calculation processing devices 30-1 to 30-N. Run in either. For example, in the case where the execution order relationship between the application 2, the application 3, and the application 4 is not determined, the calculation requesting device 20 performs three different calculation processes for the application 2, the application 3, and the application 4, respectively. The processing can be speeded up by executing in parallel by the apparatus.
