Abstract

A job managing device distributes jobs to be processed to a plurality calculation devices. The job managing device includes an information obtaining unit that obtains at least one of characteristic information or load information of the plurality of calculation devices, a job size determining unit that determines a job size to be allocated to each of the plurality of calculation devices based on the information obtained by the information obtaining unit, a job dividing unit that divides a job to be processed into divided jobs based on the job sizes determined by the job size determining unit, and a job distributing unit that distributes the divided jobs to the plurality of calculation devices.

Claims

1. A job managing device for distributing jobs to be processed to a plurality of calculation devices, the device comprising:

an information obtaining unit that obtains either characteristic information, or load information, or both characteristic information and load information of the plurality of calculation devices;

a job size determining unit that determines a job size to be allocated to each of the plurality of calculation devices based on the information obtained by the information obtaining unit;

a job dividing unit that divides a job to be processed into divided jobs based on the job sizes determined by the job size determining unit; and

a job distributing unit that distributes the divided jobs to the plurality of calculation devices.

2. The job managing device according to claim 1, wherein the plurality of calculation devices include a calculation device in charge of input/output processing, and a calculation device which is not in charge of input/output processing, and

the job size determining unit sets a job size allocated to the calculation device in charge of the input/output processing to be smaller than a job size allocated to the calculation device which is not in charge of the input/output processing.

3. The job managing device according to claim 2, wherein the plurality of calculation devices make up one computing system, and

the calculation device in charge of the input/output processing is in charge of inputs and outputs to an external device in the computing system or to a storage device in the computing system, or is in charge of inputs and outputs to an external device and to a storage device in the computing system.

4. The job managing device according to claim 1, wherein the information obtaining unit dynamically obtains at least one of a processing unit usage rate, knowledge of the presence or absence of staging processing, an input/output processing occurrence rate, or a memory swap occurrence rate in each calculation device, and the job size determining unit dynamically changes job sizes to be allocated to the plurality of calculation devices by using the information obtained by the information obtaining unit.

5. The job managing device according to claim 1, wherein the information obtaining unit refers to a job script indicating a job operation schedule to make an estimation of the load transition of each of the calculation devices, and

the job size determining unit determines job sizes to be distributed to the plurality of calculation devices based on the estimation of the load transition.

6. The job managing device according to claim 1, wherein the information obtaining unit holds a record of the estimated load transition, and

the job size determining unit determines job sizes to be distributed to the plurality of calculation devices based on the record of the load transition.

7. The job managing device according to claim 1, wherein the information obtaining unit obtains information for every CPU which is provided in each of the plurality of calculation devices,

the job size determining unit determines the job size to be allocated to each CPU,

the job dividing unit divides the job based on the job size corresponding to the CPU, and

the job distributing unit distributes the divided jobs to the CPU.

8. The job managing device according to claim 7, wherein the job size determining unit allocates no job to the CPU in charge of the input/output processing.

9. The job managing device according to claim 1, wherein the job size determining unit determines job sizes to be distributed to the plurality of calculation devices so that synchronization timings of the processing of the plural calculation devices are substantially equal to one another.

10. A job managing device for distributing a job to be processed to a plurality of calculation devices comprising:

an information obtaining unit that obtains characteristic information, load information, or both characteristic information and load information of the plurality of calculation devices;

a first distributing unit that classifies the plurality of calculation devices based on the information obtained by the information obtaining unit and distributes jobs to the classified calculation devices;

a plurality of job schedulers that manage jobs independently for every classification; and

a second distributing unit that distributes the jobs distributed to each classification to the calculation device belonging to the classification.

11. A computer-readable recording medium in which a job managing program causing a computer execute a job managing method to distribute a job to be processed to a plurality of calculation devices is recorded, the job managing program comprising:

obtaining either characteristic information or load information, or both characteristic information and load information of the plurality of calculation devices;

determining job sizes to be allocated to the plurality of calculation devices based on the obtained information;

dividing the job to be processed into divided jobs based on the determined job sizes; and

distributing the divided jobs to the plurality of calculation devices.
