  A first embodiment of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a block diagram showing the configuration of the resource management system 1 of this embodiment. The resource management system 1 of the present embodiment includes a resource management device 10 and central processing devices 20-1 to 20-n.

  The central processing units 20-1 to 20-n execute processes belonging to any of the workload classes. The workload class to which each process belongs is set by the user who instructs execution of the process. The central processing units 20-1 to 20-n share each other's data via a global memory (not shown) connected to a bus that connects each other.

  For each of the central processing units 20-1 to 20-n, the resource management device 10 grasps the status of the resource usage rate, which is the usage rate of the processing capacity with respect to the total processing capacity of the central processing unit, for each workload class. The upper limit value of the resource usage rate is adjusted between the central processing units 20-1 to 20-n.

  The resource management device 10 includes execution control units 11-1 to 11-n, storage units 12-1 to 12-n, measurement units 13-1 to 13-n, and change units 14-1 to 14-n. The adjusting unit 15 is included. The execution control units 11-1 to 11-n, the measurement units 13-1 to 13-n, the change units 14-1 to 14-n, and the adjustment unit 15 may be electronic circuits or computer programs. There is also. The storage units 12-1 to 12-n are storage circuits such as an electronic circuit or an electronic memory whose access is controlled by a computer program.

  The measurement units 13-1 to 13-n measure the resource usage rate for each workload class for the central processing units 20-1 to 20-n, respectively, and store the measurement results, respectively, in the storage units 12-1 to 12-12. -N is stored in the resource management tables 120-1 to 120-n. The measurement units 13-1 to 13-n measure the resource usage rate based on the ratio of the execution time of each workload class process in a predetermined interval.

  The execution control units 11-1 to 11-n allocate the central processing units 20-1 to 20-n to the execution waiting processes belonging to any of the workload classes, respectively. The execution control units 11-1 to 11-n refer to the resource management tables 120-1 to 120-n, respectively, and the resource usage rate of any workload class has reached the resource usage rate upper limit value Suspends the assignment of the central processing unit to the process waiting for execution belonging to the class.

  The adjustment unit 15 refers to the resource management tables 120-1 to 120-n and calculates an adjustment value of the upper limit value of the resource usage rate for each workload class in the central processing units 20-1 to 20-n.

  FIG. 3 shows a configuration example of the resource management tables 120-i and 120-j (i and j are any integers from 1 to n) in the present embodiment.

  The resource management tables 120-i and 120-j were measured by the measurement units 13-i and 13-j for each workload class in the central processing units 20-i and 20-j, respectively. Stores the resource utilization measurement value and the resource utilization upper limit value. In the resource management system 1 shown in the example of FIG. 3, classes A to C, which are three workload classes, are set.

  In the state before the change of the resource usage rate upper limit value in FIG. 3, the measured resource usage rates of the classes A to C in the central processing units 20-i and 20-j are 50%, 10%, and 10%, respectively. Yes, the resource usage rate upper limit values are 50%, 30%, and 20%, respectively.

  In any of the central processing units 20-1 to 20-n, the adjustment unit 15 performs the work when the resource usage rate measurement value reaches the resource usage rate upper limit value for any of the workload classes of classes A to C. Start calculating the adjustment value of the upper limit value of the resource usage rate for each load class. In the example of FIG. 3, the resource usage rate measurement value reaches 50% of the resource usage rate upper limit value in class A of the central processing unit 20-i.

  The adjusting unit 15 sets the resource unused rate obtained by subtracting the resource usage rate measured value from the resource usage rate upper limit value for class A in the central processing units 20-1 to 20-n except the central processing unit 20-i. A search is made for a resource unused ratio that is a value divided by the resource usage rate, and the central processing unit 20-j is selected. Note that the resource unused rate of class A in the central processing unit 20-j is 20%, and the resource unused rate is 0.67.

  The adjustment unit 15 refers to the resource management table 120-i and searches for the class B to C in the central processing unit 20-i that has the highest resource unused ratio. In the case of the example in FIG. 3, the resource unused ratios of the classes B to C in the central processing unit 20-i are 2 and 1, respectively, by the same calculation as described above. , Select class B.

  The adjustment unit 15 determines the resource usage rate measurement value of the central processing unit 20-i for the class A from the values of the resource management tables 120-i and 120-j, and the central processing units 20-i and 20-j. A value obtained by multiplying the value obtained by dividing the resource utilization rate measurement value by the resource unused rate of the central processing unit 20-j is calculated as an adjustment value of the resource utilization upper limit value. In the example of FIG. 3, for class A, the resource usage rate measurement value of the central processing unit 20-i is 50%, the sum of the resource usage rate measurement values of the central processing units 20-i and 20-j is 80%, and the central processing unit The resource unused rate of the device 20-j is 20%. Therefore, the adjustment value of the resource usage rate upper limit calculated by the adjustment unit 15 is 12.5% as a result of the above calculation.

  The adjustment unit 15 updates the class A resource usage upper limit to a value obtained by adding 12.5% to the changing unit 14-i, and subtracts the class B resource usage upper limit by 12.5%. Instructs to update to the new value. The adjusting unit 15 updates the class A resource usage upper limit to a value obtained by subtracting 12.5% from the changing unit 14-j, and adds 12.5% to the class B resource usage upper limit. Instructs to update to the new value.

  The changing units 14-1 to 14-n update the upper limit values of the resource usage rates of the respective workload classes in the resource management tables 120-1 to 120-n based on the instructions received from the adjusting unit 15, respectively. In the case of the example in FIG. 3, the changing unit 14-i updates the class A resource usage upper limit value to 62.5% obtained by adding 12.5% to 50% and class B resource usage upper limit value. Is updated to 17.5% obtained by subtracting 12.5% from 30%. The changing unit 14-j updates the class A resource usage upper limit value to 37.5%, which is obtained by subtracting 12.5% from 50%, and changes the class B resource usage rate upper limit value to 12. Update to 42.5% by adding 5%.

  Note that the ratio of the total resource utilization upper limit values of the central processing units 20-i and 20-j of classes A to C is the ratio before and after the resource management device 10 performs the above-described resource utilization upper limit change processing. Both are 5: 3: 2 and are constant.

  Next, the operation of this embodiment will be described in detail with reference to the flowchart of FIG.

  The measurement units 13-1 to 13-n measure the resource usage rates by class in the central processing units 20-1 to 20-n, respectively, and the measurement results are resource management tables in the storage units 12-1 to 12-n. Stored in 120-1 to 120-n (S101).

  When the resource usage rate does not reach the upper limit in class X (X is any one of A, B, and C) of the central processing unit 20-i (No in S102), the execution control unit 11-i The central processing unit 20-i is assigned to the process waiting for execution belonging to X (S109), and the entire process is completed.

  When the resource usage rate reaches the upper limit in class X (X is one of A, B, and C) of the central processing unit 20-i (Yes in S102), the execution control unit 11-i The allocation of the central processing unit 20-i to the process waiting for execution belonging to is suspended (S103). The adjustment unit 15 refers to the resource management tables 120-1 to 120-n, and among all the central processing units, for the class X, the value obtained by dividing the resource unused rate by the resource usage rate measured value is the largest center. The processing device 20-j is selected (S104).

  The adjustment unit 15 refers to the resource management table 120-i, and among all classes, the value obtained by dividing the resource unused rate by the resource usage rate measurement value is the largest class Y (Y is A and B excluding X). , C) (S105).

  The adjustment unit 15 refers to the resource management tables 120-i and 120-j, and for the class X, the resource usage rate measurement value of the central processing unit 20-i and the resource usage of the central processing units 20-i and 20-j. A value obtained by multiplying the value divided by the sum of the rate measurement values by the resource unused rate of the central processing unit 20-j is calculated as an adjustment value, and an instruction to adjust the resource usage rate upper limit value for classes X and Y It transmits to 14-i and 14-j (S106).

The changing unit 14-i updates the class X resource usage upper limit value to the value obtained by adding the adjustment value in the resource management table 120-i, and sets the class Y resource usage upper limit value to a value obtained by subtracting the adjustment value. Update (S107). The changing unit 14-j updates the class X utilization upper limit value to a value obtained by subtracting the adjustment value in the resource management table 120-j, and sets the class Y resource utilization upper limit value to a value obtained by adding the adjustment value. Update (S108). The execution control unit 11-i assigns the central processing unit 20-i to the execution waiting process belonging to the class X (S109),
The entire process ends.

  In this embodiment, the overall system dynamically adjusts the CPU resource allocation ratio to each workload class for some central processing units while maintaining the CPU resource allocation ratio to each workload class. Thus, there is an effect of efficiently allocating CPU resources. The reason is that when the resource usage rate reaches the upper limit value in the class X of the central processing unit 20-i, the adjustment unit 15 causes the central processing unit 20-j that has sufficient CPU resources for the class X and the central processing unit In the device 20-i, a class Y with a sufficient CPU resource is selected. Then, the adjustment unit 15 performs the central processing so that the upper limit value of the class X resource usage rate of the central processing unit 20-i increases while maintaining the distribution ratio of the CPU resources of the class X and Y as the entire system. This is because the updating units 14-i and 14-j update the resource usage rate upper limit values of the classes X and Y related to the devices 20-i and 20-j.

  In any processor in a multiprocessor system, when the resource usage rate of any workload class reaches the upper limit, resources can be allocated to processes waiting for execution in that workload class in that processor. Disappear. If the above-mentioned process waiting for execution is moved to another processor that has a sufficient resource usage rate of the workload class, process movement processing occurs, which causes a decrease in system performance.

  Moreover, if the resource usage rate upper limit value of the workload class of the processor is simply increased, the distribution ratio of CPU resources to each workload class as a whole system will deviate from the initial setting value. . The allocation ratio of CPU resources to each workload class is normally initially set to an optimal value for system performance. Therefore, if the allocation ratio of CPU resources deviates from the initial setting value, It becomes a factor of decline.

  In the present embodiment, the resource management device 10 maintains the initial setting value of the distribution ratio of CPU resources to each workload class as a whole system, and the workload of the processor whose resource usage rate has reached the upper limit value In order to increase the upper limit value of the class, it is possible to avoid the above-mentioned factor of the system performance degradation and to efficiently redistribute the CPU resources.

  In the present embodiment, for the class X, the adjustment unit 15 selects the central processing unit 20-j having a sufficient CPU resource from among a plurality of central processing units, and the above-mentioned resource unused ratio is the largest. It is supposed to be. In the central processing unit 20-i, the adjustment unit 15 also selects the class Y having a sufficient CPU resource from among a plurality of workload classes. Similarly, the resource unused ratio is the largest.

  That is, the adjustment unit 15 is affected even if the resource usage rate upper limit value is lowered as a target for adjusting the resource usage rate upper limit value in order to increase the resource usage rate upper limit value of the class X in the central processing unit 20-i. Select the smallest central processor and workload class. Therefore, the resource management apparatus 10 can adjust the resource usage rate upper limit value while suppressing the influence on the system performance as much as possible.

  Then, the adjustment unit 15 uses the resource unused rate of class X in the central processing unit 20-j as the adjustment value of the resource usage upper limit value, and the resource usage rate measurement values of the central processing units 20-i and 20-j. The value of the share of the central processing unit 20-i when distributed in proportion.

  That is, the adjustment unit 15 calculates an adjustment value on the assumption that the ratio of the resource usage rates of the central processing units 20-i and 20-j regarding the class X does not change even after the adjustment of the resource usage rate upper limit value. Therefore, the resource management device 10 can redistribute the CPU resource with an optimum value in accordance with the current resource usage status in the system having the above-mentioned premise characteristics.

  Note that the procedure by which the adjustment unit 15 calculates the adjustment value of the resource usage rate upper limit value is not limited to the above calculation procedure.

  The execution control units 11-1 to 11-n, the storage units 12-1 to 12-n, the measurement units 13-1 to 13-n, and the change units 14-1 to 14-n are respectively central processing units. It may be mounted on the devices 20-1 to 20-n.

Further, the resource management device 10 does not include an execution control unit, a storage unit, a measurement unit, and a change unit for each central processing unit, but performs processing corresponding to all the central processing units. In some cases, each of the storage unit, the storage unit, the measurement unit, and the change unit is provided.
<Second Embodiment>
Next, a second embodiment of the present invention will be described in detail with reference to the drawings.

  The configuration of the second embodiment of the present invention is the same as the block diagram of the first embodiment shown in FIG. In the present embodiment, the configuration of the resource management tables 120-1 to 120-n and the operation of the adjustment unit 15 are different from those in the first embodiment.

  A configuration example of the resource management tables 120-i and 120-j in this embodiment is shown in FIG.

  In addition to the first embodiment, the resource management tables 120-i and 120-j are waiting for execution for each workload class in the central processing units 20-i and 20-j, respectively. Stores the number of processes.

  As in the first embodiment, the adjusting unit 15 uses the resource usage measurement value for the workload class of any of classes A to C in any of the central processing units 20-1 to 20-n. When the rate upper limit value is reached, the calculation operation of the adjustment value of the upper limit value of the resource usage rate for each workload class starts.

  The adjustment unit 15 is a process that is a value obtained by dividing the resource unused rate by the number of processes waiting for execution of the class A for the class A in the central processing units 20-1 to 20-n except the central processing unit 20-i. The one with the largest unit unused rate is searched, and the central processing unit 20-j is selected. Note that the resource unused rate of class A in the central processing unit 20-j is 20%, and the process unit unused rate is 4%.

  The adjustment unit 15 refers to the resource management table 120-i and searches for a class B to C that has the highest process unit unused rate. In the case of the example in FIG. 4, the process unit unused rates of class B to C in the central processing unit 20-i are 10% and 5%, respectively. select.

  The adjustment unit 15 determines the number of processes waiting for execution of the central processing unit 20-i for the class A from the values of the resource management tables 120-i and 120-j, and executes the execution of the central processing units 20-i and 20-j. A value obtained by multiplying the value divided by the sum of the number of waiting processes and the resource unused rate of the central processing unit 20-j is calculated as an adjustment value of the resource usage rate upper limit value. In the example of FIG. 4, for class A, the number of processes waiting for execution of the central processing unit 20-i is 5, the sum of the number of processes waiting for execution of the central processing units 20-i and 20-j is 10, and the central processing unit 20-j The resource unused rate is 20%. Accordingly, the adjustment value of the resource usage rate upper limit value calculated by the adjustment unit 15 is 10% as a result of the above calculation.

  The adjustment unit 15 updates the class A resource usage upper limit to a value obtained by adding 10% to the changing unit 14-i, and updates the class B resource usage upper limit to a value obtained by subtracting 10%. To instruct. The adjustment unit 15 updates the class A resource usage upper limit to a value obtained by subtracting 10%, and updates the class B resource usage upper limit to a value obtained by adding 10% to the changing unit 14-j. To instruct.

  The changing units 14-1 to 14-n update the upper limit values of the resource usage rates of the respective workload classes in the resource management tables 120-1 to 120-n based on the instructions received from the adjusting unit 15, respectively. In the case of the example in FIG. 4, the changing unit 14-i updates the resource usage upper limit value of class A to 60% obtained by adding 10% to 50%, and changes the resource usage rate upper limit value of class B to 30%. Update to 20% by subtracting 10% from. The changing unit 14-j updates the class A resource usage rate upper limit value to 40% obtained by subtracting 10% from 50%, and the class B resource usage rate upper limit value obtained by adding 10% to 30% 40 Update to%.

  Note that the ratio of the total resource utilization upper limit values of the central processing units 20-i and 20-j of classes A to C is the ratio before and after the resource management device 10 performs the above-described resource utilization upper limit change processing. Both are 5: 3: 2 and are constant.

  In the present embodiment, as in the first embodiment, the entire system maintains the CPU resource allocation ratio to each workload class, and the CPU to some workload classes for some central processing units. There is an effect of efficiently adjusting CPU resource allocation by dynamically adjusting the resource allocation ratio. The reason is the same as in the first embodiment.

  In the present embodiment, the adjustment unit 15 selects the central processing device 20-j having a sufficient CPU resource from among the plurality of central processing devices for the class X whose resource usage rate has reached the upper limit value. It is assumed that the process unit unused rate is the maximum. In the central processing unit 20-i, the adjustment unit 15 selects the class Y having a sufficient CPU resource from among a plurality of workload classes.

  That is, the adjustment unit 15 is affected even if the resource usage rate upper limit value is lowered as a target for adjusting the resource usage rate upper limit value in order to increase the resource usage rate upper limit value of the class X in the central processing unit 20-i. The smallest central processing unit and workload class are selected based on information on the number of processes waiting to be executed. Therefore, the resource management apparatus 10 can adjust the resource usage rate upper limit value while suppressing the influence on the system performance as much as possible.

  Then, the adjustment unit 15 uses the resource unused rate of class X in the central processing unit 20-j as the adjustment value of the resource usage rate upper limit value, and the ratio of the number of waiting processes in the central processing units 20-i and 20-j. The value of the equity of the central processing unit 20-i when distributed in

  That is, the adjustment unit 15 calculates an adjustment value based on the premise that each process waiting for execution of the central processing units 20-i and 20-j related to class X uses CPU resources equally. Therefore, the resource management device 10 can redistribute the CPU resource with an optimum value in accordance with the current resource usage status in the system having the above-mentioned premise characteristics.

Note that the procedure by which the adjustment unit 15 calculates the adjustment value of the resource usage rate upper limit value is not limited to the above calculation procedure.

  The storage unit 12 stores the upper limit value of the ratio to the total processing capacity for each of the central processing units 20-1 to 20-n that can be assigned to the process of the class corresponding to the class to which the process belongs.

  The measuring unit 13 measures the above-mentioned ratio for each class for each of the central processing units 20-1 to 20-n.

  When assigning a central processing unit to a process, the execution control unit 11 does not assign a class whose process has reached the upper limit value to the process.

  In the first central processing unit, which is one of the central processing units 20-1 to 20-n, the changing unit 14 has a resource usage rate of the first class that is one of a plurality of classes, with an upper limit. When the value is reached, the first class in the first central processing unit and the upper limit value of the second class selected from a plurality of classes according to a predetermined standard, respectively, add a predetermined adjustment value, And change to the subtracted value.

  The changing unit 14 sets the upper limit values of the first and second classes in the second central processing unit selected from the central processing units 20-1 to 20-n on a predetermined basis, respectively. The adjustment value is subtracted and changed to the added value.

  In this embodiment, as in the first and second embodiments, as a whole system, the CPU resource to each class is partially assigned to the central processing unit while maintaining the distribution ratio of the CPU resources to each class. It is effective in efficiently allocating CPU resources by dynamically adjusting the distribution ratio. The reason is that when the resource usage rate reaches the upper limit value in the first class of the first central processing unit, the changing unit 14 selects the second central processing unit and the second class according to a predetermined standard. select. The changing unit 14 increases the first class resource usage upper limit value of the first central processing unit while maintaining the distribution ratio of the first and second class CPU resources as the entire system. This is because the first and second resource utilization upper limit values related to the first and second central processing units are updated.

  The reference for the changing unit 14 to select the second central processing unit and the second class may be the same as or different from the reference in the first or second embodiment. The value of the adjustment value at which the changing unit 14 adjusts the resource usage rate is a value calculated by the same calculation procedure as that of the first or second embodiment, or the first and second embodiments. The change unit 14 may receive a value calculated by a different calculation procedure from the outside.
