Description

  The present invention relates to a job management apparatus, a job management method, and a job management program.

  2. Description of the Related Art Conventionally, job management apparatuses that submit jobs such as batch processing and automatic operation processing to servers connected via a network are widely known. The job management apparatus has a distributed control function for designating a job submission destination server from a plurality of servers and submitting jobs to the designated server. Therefore, the job management device uses this distributed control function and does not submit jobs to fixed servers, but instead automatically distributes jobs to servers with sufficient execution multiplicity. Can avoid overloading.

  By the way, in recent years, power consumption has increased rapidly due to reasons such as improved processor performance and higher density of computing environment, and the amount of heat generated by servers has also increased. This increase in heat generation may affect the stable operation of the server. However, although the conventional job management apparatus adopts a distributed control function for the purpose of ensuring stable operation of the server, it does not avoid submitting a job to a server having a high machine temperature. Therefore, even if the distributed control function is adopted, the actual situation is that no problem can be dealt with due to the server heat generation.

  Therefore, the conventional job management apparatus has a function of measuring the machine temperature of each server, determining a server having a low machine temperature as a job submission destination based on the measurement result, and submitting a job to this job submission destination server. Are known.

  For example, two of the three servers arranged adjacent to each other have a large machine load due to a large amount of jobs being input and the machine temperature is high, while the remaining one server is completely Assume that the machine temperature is low because no jobs have been submitted. Under such circumstances, since the machine temperature of the two servers is high, the ambient temperature of the remaining one server is also high.

  However, in the above job management apparatus, although the ambient temperature rises due to the operation of the adjacent server and is in a high temperature region, the machine temperature of a single server adjacent to the adjacent server is low. Is determined as the job submission destination server.

  Therefore, an object of one aspect is to avoid job submission to a server group in a high temperature region.

  Embodiments of a job management apparatus, a job management method, and a job management program disclosed in the present application will be described below in detail with reference to the drawings. Note that the present invention is not limited to the embodiments.

  FIG. 1 is a block diagram illustrating the configuration of the job management system according to the first embodiment. The job management system 1 illustrated in FIG. 1 includes, for example, a plurality of servers 2 arranged in a server room, and a job management server 3 that inputs jobs to the plurality of servers 2. When the server 2 is connected to the job management server 3 and detects a job input from the job management server 3, the server 2 executes processing corresponding to the job.

  The job management server 3 is connected to a plurality of servers 2 via a network, and has a distributed control function for submitting jobs to an arbitrary server 2 from the plurality of servers 2, and a control unit 10 that controls the entire job management server 3. Have The control unit 10 includes a temperature acquisition unit 11, a management unit 12, a management table 13, a group setting unit 14, a group selection unit 15, a server selection unit 16, and a job input unit 17.

  The temperature acquisition unit 11 acquires the supply air temperature and the internal temperature of each server 2 via a network. The management unit 12 registers the supply air temperature and the internal temperature of each server 2 acquired by the temperature acquisition unit 11 in the management table 13 for each server 2.

  The group setting unit 14 compares the supply air temperature of each server 2 based on the supply air temperature for each server 2 registered in the management table 13, and there is a predetermined correlation between the supply air temperatures based on the comparison result. Server 2 is identified. The group setting unit 14 sets a correlation group corresponding to a server group having a predetermined correlation based on the identification result. That is, the server group of each correlation group can be considered as a server group arranged in a certain area in the server room, for example. Then, when the correlation group is set by the group creation unit 14, the management unit 12 registers the corresponding correlation group in association with the server 2 in the management table 13.

  The group selection unit 15 selects a server group correlation group optimal as a job input destination based on the supply air temperature of the server group for each correlation group registered by the management table 13. That is, the group selection unit 15 selects a group of server groups in a low temperature region that is optimal as a job input destination.

  Based on the internal temperature of each server 2 registered by the management table 13, the server selection unit 16 selects the optimum server 2 as a job input destination from the server group of the correlation group selected by the group selection unit 15. That is, for example, the server selection unit 16 sets a server having the lowest internal temperature of the server 2 as a job input destination from the server group of the correlation group selected by the group selection unit 15.

  The job submission unit 17 submits a job corresponding to the job submission request to the server 2 selected by the server selection unit 16. As a result, the job submission unit 17 can submit a job from the server group having the lowest supply air temperature to the server 2 having the lowest internal temperature, that is, the server 2 that is the optimum job submission destination.

  Therefore, in the first embodiment, it is possible to identify a server group in a high-temperature region (heat accumulation) that is inappropriate as a job input destination based on the supply air temperature of the server group in units of groups, and to the server group in the high-temperature region based on the identification result. Job submission can be avoided. In addition, the heat accumulation occurs in a hot place in the server room, and not only the temperature of the adjacent server rises, but also, for example, when dust accumulates on the server or when objects are placed in front of the server. But it happens. Furthermore, in the first embodiment, it is possible to select a server group in an optimal low temperature region as a job input destination, and to input a job from the server group to the optimal low temperature server 2 as a job input destination. For example, out of three adjacent servers 2, a large number of jobs are input to two servers and the machine load is heavy, and the machine temperature is high, while the remaining one server 2 is Suppose the machine temperature is low because no jobs are submitted. Even in such a situation, in the first embodiment, since the supply air temperature of the server group in the group unit can be distinguished from the server group in the high temperature region that is inappropriate as the job input destination, it is possible to avoid the job input to the server group in the high temperature region. .

  Next, the job management system according to the second embodiment will be described in detail. FIG. 2 is a block diagram illustrating the configuration of the job management system according to the second embodiment. The job management system 1A shown in FIG. 2 includes, for example, a plurality of servers 2A arranged in a server room, and a job management server 3A that inputs jobs to the plurality of servers 2. The server 2A includes a communication unit 21, a job execution unit 22, and a supply air temperature measurement unit 23.

  The communication unit 21 is a communication interface that controls communication with a network. When the job execution unit 22 detects job input from the job management server 3A, the job execution unit 22 executes processing corresponding to the job. The supply air temperature measurement unit 23 measures the supply air temperature of the server 2A. Further, it is assumed that the server 2A incorporates a monitoring program for measuring the current temperature of an internal CPU (Central Processing Unit) (not shown).

  Further, the job management server 3A includes a communication unit 31 and a control unit 10A. The communication unit 31 is a communication interface that controls communication with a network. The control unit 10A has a distributed control function for submitting jobs to an arbitrary server 2A from among the plurality of servers 2 via the communication unit 31, and controls the entire job management server 3A. It is assumed that the control unit 10A recognizes the arrangement position of each server 2A in the server room. FIG. 3 is a block diagram illustrating the configuration of the job management server 3A according to the second embodiment. The control unit 10A includes a fixed information acquisition unit 11A, a variable information acquisition unit 11B, a management unit 12A, a management table 13A, a group setting unit 14A, a group selection unit 15A, a server selection unit 16A, and a job input unit 17A.

  The fixed information acquisition unit 11A acquires the fixed information of each server 2A via the network. Note that the fixed information includes a server name that identifies the server 2A and a CPU reference temperature that is a reference temperature of the CPU inside the server 2A. The variable information acquisition unit 11B acquires variable information of each server 2A via a network. The variable information includes the current supply air temperature of the server 2A and the current CPU temperature that is the current temperature of the CPU inside the server 2A.

  The management table 13A manages the input destination selection file. The management table is, for example, a semiconductor device such as a RAM (Random Access Memory), a ROM (Read Only Memory), or a flash memory, or a storage device such as a hard disk or an optical disk. FIG. 4 is an explanatory diagram showing an example of the input destination selection file. As shown in FIG. 4, the input destination selection file 50 manages a correlation group 55 described later for each server 2 in addition to the server name 51, the CPU reference temperature 52, the current CPU temperature 53, and the supply air temperature 54. The management unit 12A controls the management table 13A and registers the server name 51 and the CPU reference temperature 52, which are fixed information acquired by the fixed information acquisition unit 11A, in the input destination selection file 50 of the corresponding server 2A. Furthermore, the management unit 12A registers the supply air temperature 54 and the current CPU temperature 55, which are variable information acquired by the variable information acquisition unit 11B, in the input destination selection file 50 of the corresponding server 2A.

  The group setting unit 14A compares the supply air temperature of each server 2 based on the supply air temperature for each server 2A registered in the input destination selection file 50, and a predetermined correlation between the supply air temperatures based on the comparison result. Identifies the server 2 with Further, the group setting unit 14 sets a correlation group corresponding to a server group having a predetermined correlation based on the identification result. The group setting unit 14 </ b> A includes a temporary group setting unit 41, a sample job input unit 42, and a correlation group setting unit 43.

  The temporary group setting unit 41 sets a temporary group associated with a server group in which the supply air temperature 54 of each server 2A approximates within a predetermined error range based on the supply air temperature 54 of each server 2A in the input destination selection file 50. To do. The temporary group is a group of servers having a predetermined error range in which the supply air temperature is substantially equal.

  The sample job submission unit 42 submits a sample job from a server group in the temporary group to an arbitrary server 2A. The sample job corresponds to a batch job in which a large number of CPUs on the input destination server 2 operate or a job having a long execution time. The correlation group setting unit 43 sequentially acquires the supply air temperature within the monitoring time of each server 2A in the temporary group at predetermined time intervals through the variable information acquisition unit 11B in response to the input of the sample job. Moreover, the correlation group setting part 43 creates the regression line which shows the time transition regarding a supply air temperature for every server 2A based on the acquisition result of the supply air temperature of each server 2A. In addition, the correlation group setting unit 43 compares the regression lines of the servers 2A, and identifies the server 2A having a correlation with the slope of the regression line based on the comparison result. Further, the correlation group setting unit 43 sets a correlation group corresponding to a server group having a correlation with the slope of the regression line based on the identification result. When the correlation group setting unit 43 sets the correlation group, the management unit 12A registers the correlation group 55 corresponding to the server 2 in the input destination selection file 50.

  When the group selection unit 15A detects a job submission request, the group selection unit 15A selects an optimum server group correlation group 55 as a job submission destination based on the supply air temperature 54 of the server group for each correlation group 55. The supply air temperature 54 of the server group for each correlation group 55 corresponds to, for example, the average value of the supply air temperatures 54 of all the servers 2A in the corresponding correlation group 55 in the input destination selection file 50. Therefore, the group selection unit 15A selects the correlation group 55 whose average value of the supply air temperature 54 is the lowest temperature based on the average value of the supply air temperature 54 for each correlation group 55. That is, the group selection unit 15A selects a server group in a low temperature region that is optimal as a job input destination.

  The server selection unit 16A selects an optimal server 2A as a job input destination from the server group of the correlation group 55 selected by the group selection unit 15A based on the CPU temperature difference result of each server 2A. The CPU temperature difference result corresponds to the difference between the current CPU temperature 53 and the CPU reference temperature 52 of the server 2A. For example, when the difference between the current CPU temperature 53 and the CPU reference temperature 52 deviates in the + direction, the current CPU temperature is in the higher temperature direction, and when the difference between the current CPU temperature 53 and the CPU reference temperature 52 deviates in the-direction. The current CPU temperature is considered to be in the low temperature direction. That is, for example, the server selection unit 16A selects the server 2A having the lowest CPU temperature difference result from the server group of the correlation group 55 selected by the group selection unit 15A as the optimum server 2A as the job input destination. .

  The job submission unit 17A submits a job corresponding to the job submission request to the server 2A selected by the server selection unit 16A. As a result, the job input unit 17A can input a job from the server group having the lowest supply air temperature to the server 2A having the lowest CPU temperature difference result, that is, the optimal job input destination server 2A.

  Next, the operation of the job management system 1A according to the second embodiment will be described. First, a description will be given of the pre-processing until the submission destination selection file 50 that is the basis for selecting the job submission destination server 2A is set. FIG. 5 is a flowchart showing the processing operation of the control unit 10A related to the preliminary processing.

  In FIG. 5, the control unit 10A acquires fixed information and variable information for each server 2A in accordance with a predetermined timing, and registers the fixed information and variable information in the input destination selection file 50 for each server 2A. Processing is executed (step S11). The predetermined timing corresponds to a timing that is periodically activated every predetermined time, for example, every 12 hours. Then, the control unit 10A groups the server group considering the supply air temperature 54 and the position information into the correlation group 55 based on the registered charging destination selection file 50, and registers the correlation group 55 in the charging destination selection file 50. Correlation group registration processing is executed (step S12). After executing the correlation group registration process, the control unit 10A ends the processing operation illustrated in FIG.

  Next, the processing contents of the input destination selection file registration process in step S11 shown in FIG. 5 will be described in detail. FIG. 6 is a flowchart showing the processing operation of the control unit 10A related to the input destination selection file registration process.

  In FIG. 6, the fixed information acquisition unit 11A in the control unit 10A acquires the fixed information from each server 2A (step S21). The fixed information includes a server name 51 for identifying the server 2A and a CPU reference temperature 52 of the server 2A. Furthermore, when acquiring the fixed information, the management unit 12A in the control unit 10A registers the server name 51 and the CPU reference temperature 52 of the fixed information in the input destination selection file 50 for each server 2A (step S22).

  Furthermore, the variable information acquisition unit 11B in the control unit 10A acquires variable information from each server 2A (step S23). The variable information includes the current CPU temperature 53 and the supply air temperature 54 in the server 2A. In addition, the supply air temperature 54 corresponds to, for example, a plurality of supply air temperatures 54 that are sequentially measured at a predetermined time interval within a certain period immediately before the start of the predetermined timing from the start of the pre-processing. Further, when the variable information is acquired, the management unit 12A registers the current CPU temperature 53 and the supply air temperature 54 of the variable information in the input destination selection file 50 for each server 2A (step S24), and ends this processing operation. To do. As a result, in the input destination selection file, as shown in FIG. 7, the server name 51, the CPU reference temperature 52, the current CPU temperature 53, and the supply air temperature 54 are registered for each server 2A.

  In the input destination selection file registration process shown in FIG. 6, the server name 51, the CPU reference temperature 52, the current CPU temperature 53, and the supply air temperature 54 are acquired from each server 2A at each predetermined timing, and these information are stored in the input destination selection file 50. Can be registered within.

  In FIG. 6, after the fixed information is acquired in step S21, the variable information is acquired in step S23. However, the fixed information may be acquired after the variable information is acquired. In FIG. 6, fixed information and variable information may be acquired in parallel. Further, in FIG. 6, after obtaining the fixed information and variable information, the fixed information and variable information may be registered in the input destination selection file 50.

  Next, the processing contents of the correlation group registration processing in step S12 shown in FIG. 5 will be described in detail. FIG. 8 is a flowchart showing the processing operation of the control unit 10A related to the correlation group registration process, and FIG. 9 is an explanatory diagram showing the relationship between the average values of the supply air temperatures of the servers 2A used when setting the temporary group. FIG. 10 is an explanatory diagram showing an example of the arrangement status of the server 2A in the server room and the setting status of the temporary group, and FIG. 11 is a time transition (regression line) of the supply air temperature of each server 2A used when setting the correlation group. FIG.

  In FIG. 7, the temporary group setting unit 41 in the control unit 10A calculates the average value of the supply air temperature 54 in the input destination selection file 50 for each server 2A (step S31). The temporary group setting unit 41 compares the average value of the supply air temperature 54 of each server 2A, and identifies the server 2A having the same average value of the supply air temperature 54 based on the comparison result. Further, the temporary group setting unit 41 sets a temporary group corresponding to a server group having an average value of the supply air temperature 54 substantially equal based on the identification result (step S32). In the example of FIG. 8, the average value of the server A (2A) is 26 ° C., the average value of the server B (2A) is 26 ° C., the average value of the server C (2A) is 26 ° C., and the server D (2A) The average value was 25 ° C., the average value of server E (2A) was 24 ° C., the average value of server F (2A) was 30 ° C., and the average value of server G (2A) was 31 ° C. In this case, as shown in FIG. 10, the temporary group setting unit 41 sets the servers A to E (2A) having substantially the same average value of the supply air temperature 54 to the temporary group “1” and the servers F and G. (2A) is set to the temporary group “2”.

  Further, when a temporary group is set, the sample job execution unit 42 in the control unit 10A designates an arbitrary temporary group from these temporary groups (step S33), and sends it to an arbitrary server 2A in the designated temporary group. In response to this, a sample job is submitted (step S34). For example, in the case of the temporary group “1”, the arbitrary server 2A in the temporary group is any one server 2A in the servers A to E (2A).

  When a sample job is input to any server 2A in the temporary group, the correlation group setting unit 43 in the control unit 10A starts a monitoring timer that measures a monitoring time, for example, 1 hour (step S35). After starting the monitoring timer, the correlation group setting unit 43 measures the supply air temperature of each server 2A in the temporary group while sequentially measuring the supply air temperature of each server 2A at regular intervals, for example, every 5 minutes. The data is sequentially stored in a work area (not shown) in the setting unit 14A (step S36). Then, the correlation group setting unit 43 determines whether or not the monitoring timer started in step S35 has expired while sequentially measuring and storing the measurement time and the supply air temperature of each server 2A in the temporary group ( Step S37). That is, in the work area, for example, a total of twelve supply air temperatures measured sequentially at regular intervals, for example, every five minutes, within a monitoring time, for example, one hour, are stored in units of the server 2A.

  When the monitoring timer has not timed up (No at Step S37), the correlation group setting unit 43 proceeds to Step S36 to continue the sequential measurement and storage of the measurement time and the supply air temperature of each server 2A. Further, when the monitoring timer expires (Yes at Step S37), the correlation group setting unit 43 calculates a regression line of the supply air temperature shown in FIG. 11 based on the supply air temperature and the measurement time sequentially stored at Step S36. Created for each server 2A (step S38).

  The correlation group setting unit 43 compares the slope transitions of the regression lines of the supply air temperatures of the servers 2A, and identifies the servers 2A whose slope transitions are substantially the same based on the comparison result (step S39). Furthermore, the correlation group setting unit 43 sets a correlation group based on the identification result, with the server groups having the same tendency in inclination transition, that is, correlation (step S39). In the example of FIG. 11, in the inclination transition of the server A (2A), the supply air temperature rises during the sample job execution period, and the supply air temperature decreases after the sample job execution period is completed. Similarly, the inclination transitions of the servers B and C (2A) are almost the same as the server A (2A), whereas the inclination transitions of the servers D and E (2A) are different from the server A (2A). As a result, the correlation group setting unit 43 regards the servers A to C (2A) having the same inclination tendency of the regression line of the supply air temperature as the correlated server groups and sets them as the same correlation group. Furthermore, the correlation group setting unit 43 excludes servers D and E (2A) having different inclination transitions from the same correlation group as the server 2A having no correlation.

  Then, when a correlation group is set in the correlated server group, the correlation group setting unit 43 registers these correlated servers 2A in the input destination selection file 50 as the same correlation group (step S40). The control unit 10 </ b> A recognizes a server group having a correlation based on the correlation group 55 of the input destination selection file 50.

  Furthermore, when the correlation group 55 of the corresponding server 2A is registered in the input destination selection file 50, the correlation group setting unit 43 determines whether or not there is a correlation group exclusion server 2A in the designated temporary group ( Step S41). When there is no correlation group exclusion server 2A (No at Step S41), the correlation group setting unit 43 determines whether there is an unspecified temporary group (Step S42). When there is an undesignated temporary group (Yes at Step S42), the control unit 10A proceeds to Step S33 to designate an undesignated temporary group.

  Further, when there is no undesignated temporary group (No at Step S42), the control unit 10A ends this processing operation. Further, when there is a correlation group exclusion server 2A in the temporary group (Yes in step S41), the control unit 10A determines whether there are a plurality of correlation group exclusion servers 2A (step S43).

  When there are a plurality of correlation group exclusion servers 2A (Yes in step S43), the control unit 10A designates the exclusion server 2A as a temporary group (step S44), and sends a sample job to an arbitrary server 2A in the designated temporary group. The process proceeds to step S34 in order to make an input. Further, when there are not a plurality of correlation group exclusion servers 2A (No at Step S43), the control unit 10A sets a correlation group at the exclusion server 2A (Step S45) and registers the same correlation group in the input destination selection file. The process proceeds to M2 in the figure.

  In the correlation group registration process shown in FIG. 8, a temporary group is set with a server group having an average value of the supply air temperature substantially equal, a sample job is submitted to an arbitrary server in the temporary group, and within the monitoring time after the sample job is submitted. The supply air temperature at every predetermined interval is measured for every server 2A in the temporary group. Further, in the correlation group registration process, a regression line is created based on the supply air temperature for all the servers 2A in the temporary group, server groups having almost the same slope transition of the regression line are set as the same correlation group, and an input destination selection file The correlation group 55 is registered for each server 2A in 50. As a result, the control unit 10A can recognize the server 2A in the same correlation group 55 based on the correlation group 55 in the input destination selection file 50.

  In FIG. 8, a regression line of the supply air temperature is created for each server 2 in step S38, but another correlation function may be calculated. In FIG. 8, the server groups having the same trend in the regression line slope are set in the same correlation group in step S39. However, if there is a condition for identifying the correlation of the regression line, another condition is set. May be used.

  Next, a job submission process for selecting the job submission destination server 2A using the submission destination selection file 50 registered in the pre-process shown in FIG. 5 and submitting a job to the selected job submission destination server 2A will be described. FIG. 12 is a flowchart showing the processing operation of the control unit 10A related to the job input process.

  In FIG. 12, the control unit 10A determines whether or not a job submission request has been detected (step S51). When the group selection unit 15A in the control unit 10A detects a job submission request (Yes in step S51), the air supply of all the servers 2A in the correlation group 55 for each correlation group 55 in the submission destination selection file 50 An average value of the temperature 54 is calculated (step S52). For example, when the correlation group “1” is the servers A to C (2A), the average value 54 of the supply air temperature for each correlation group 55 is the supply air for the three servers A to C (2A). It is calculated by dividing the addition result of the temperature 54 by 3 for the number.

  When the average value of the supply air temperature 54 is calculated for each correlation group 55, the group selection unit 15A determines whether or not there is a correlation group 55 having the lowest supply air temperature average value (step S53). When there is a correlation group 55 whose supply air temperature average value is the lowest temperature (Yes at Step S53), the group selection unit 15A determines whether there are a plurality of corresponding groups (Step S54).

  When there are a plurality of corresponding groups (Yes at Step S54), the group selection unit 15A selects the correlation group 55 as an input destination group (Step S55). When the input destination group is set, the server selection unit 16A in the control unit 10A sets the server 2A whose CPU temperature 53 is currently equal to or lower than the CPU reference temperature 52 based on the input destination selection file 50 of each server 2A in the input destination group. It is determined whether or not there is (step S56).

  When the server selection unit 15A includes a server 2A in which the current CPU temperature 53 is equal to or lower than the CPU reference temperature 52 in the input destination group (Yes in step S56), the server selection unit 15A selects the server 2A having the lowest CPU temperature 53 in the input destination group. Select (step S56A). When the server selection unit 15A selects the server 2A having the lowest CPU temperature, the server selection unit 15A determines whether there are a plurality of corresponding servers 2A (step S57). When there are not a plurality of corresponding servers (No at Step S57), the server selection unit 15A selects the corresponding server 2A as the destination server 2A (Step S58), and submits a job to the destination server 2A (Step S59). The processing operation shown in FIG. As a result, the job management server 3A can submit a job to the optimum server 2A in the correlation group 55 corresponding to the low temperature region.

  Further, when there are a plurality of corresponding servers 2A (Yes at Step S57), the control unit 10A randomly selects the server 2A from the plurality of corresponding servers 2A using the existing distributed control function (Step S60), and the server 2A Is selected as the destination server 2A, the process proceeds to step S58. In addition, when there is no server 2A whose current CPU temperature 53 is equal to or lower than the CPU reference temperature 52 (No in step S56), the control unit 10A selects the server 2A whose current CPU temperature 53 is the lowest (step S56). S61) The process proceeds to step S57 in order to determine whether or not there are a plurality of corresponding servers 2A.

  Further, when the control unit 10A does not detect the job submission request (No at Step S51), the control unit 10A ends the processing operation illustrated in FIG. In addition, when there is no correlation group having the lowest supply air temperature average value (No at Step S53) or when there are a plurality of corresponding groups (No at Step S54), the control unit 10A executes the existing distributed control function from the corresponding group. The group is selected at random (step S62), and the process proceeds to step S55 to select this group as the input destination group.

  In the job submission process shown in FIG. 12, when a job submission request is detected, the average value of the supply air temperature of the server group in the correlation group unit in the submission destination selection file 50 is calculated, and the average value of the supply air temperature is the lowest temperature. Select the server group as the destination group. Further, in the job submission process, the server 2A having the lowest CPU temperature difference result among all the servers 2A in the submission destination group is selected as the job submission destination server 2A, and the job is submitted to this job submission destination server 2A. As a result, jobs are sent from the server group in the low temperature region to the optimum server 2A by avoiding the job input to the server group in the high temperature region in consideration of the supply air temperature in the group unit, that is, the server group, not the server 2A unit Can be thrown in. Therefore, by submitting a job to the server 2A of the server group in the low temperature region, the probability of the high temperature region due to the job submission can be greatly reduced, and by reducing the high temperature region, a stable job on the job submission server 2A side Processing capacity can be secured.

  In FIG. 12, the correlation group having the lowest supply air temperature average value in the correlation group is selected in step S53. However, the correlation group having the low supply air temperature average value may be selected. good. In FIG. 12, the server 2 having the lowest CPU temperature difference result is selected from the servers 2 in the input destination group in step S56 and step S56A. However, the low-temperature server 2 may be selected. In FIG. 12, the server 2 having the lowest CPU temperature is selected in step S61. However, the server 2 having a low temperature that does not become a high temperature region may be selected.

  Therefore, in the second embodiment, it is possible to recognize the temperature status of the server group in the server room based on the supply air temperature in the correlation group unit, that is, the server group unit, using the input destination selection file 50.

  Furthermore, in the second embodiment, the correlation job group in the job destination selection file 50, that is, the group having the lowest supply air temperature for each server group is selected as the job job destination group, so the optimum job job destination in the server room is selected. Recognize groups.

  Furthermore, in the second embodiment, since the server with the lowest CPU temperature difference result in the job submission destination group is selected as the job submission destination server, the optimum job submission destination server in the server room can be recognized.

  Furthermore, in the second embodiment, by submitting a job to the job submission destination server, it is possible to avoid submitting a job to a server group in a high temperature region and to secure stable job processing capability on the job submission server 2A side.

  In the second embodiment, when the job selection server 2A is selected by the server selection unit 16A, the job is input to the job input server 2A through the job input unit 17. However, the server selection unit 16A notifies the other job management server 3A of the server selection result, and inputs a job from the job input unit 17A in the other job management server 3A to the input destination server 2A. Also good.

  In addition, all or part of the processes described as being automatically performed among the processes described in the present embodiment may be performed manually. For example, the content of the submission destination selection file 50 is displayed on the monitor of the job management server 3A, and the user manually performs the job submission processing in FIG. 12 while visually checking the content of the submission destination selection file 50 on the monitor. Also good.
