DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below in detail with reference to the drawings.

Referring to FIG. 1, one embodiment of the present invention is:
It comprises a job input and translation management function 2 for inputting and translating a job, a scheduling management function 3, a scheduling queue 5, and a job execution management function 6.

The scheduling management function 3 includes a function 4 for registering a job in the scheduling queue 5 and a function 16 for deleting a job from the scheduling queue 5.

The scheduling queue 5 includes a scheduling queue A (class A) 8 and a scheduling queue B (class B) 9. Although the scheduling queue 5 is usually composed of a plurality of classes, this embodiment will be described as having two classes.

The class A8 includes a job 1 (10) registered first in the class A8, a job 2 (11) registered second in the class A8, and a job 4 registered third in the class A8. (12).

The class B9 includes a job 3 (13) registered first in the class B9, a job 4 (14) registered second in the class B9, and a job 5 registered third in the class B9. (15).

The job input to the job input and translation management function 2 includes the input job 4 (1) and the user-specified value 7 of the job execution class for scheduling the job 4.

A job scheduling class management system according to an embodiment of the present invention will be described below with reference to FIGS.
This will be described with reference to FIG.

When the job 4 (1) is input (step 21), the job input / translation management function 2 translates the job 4 (1) (step 22) and transfers it to the scheduling management function 3.

The scheduling management function 3 registers the translated job 4 (1) in the scheduling queue 5 by the registration function 4. The scheduling management function 3
When the job becomes executable, the jobs are sequentially taken out of the scheduling queue 5 using the deletion function 16 and passed to the job execution management function 6 (step 24).

The registration function 4 assigns, for example, CLASS = (A,
If B) is specified, it is registered in the class A8 or the class B9 in the scheduling queue 5 in FIFO order (step 23). In other words, in the case of class A8, since job 1 (10) and job 2 (11) have already been registered, they are registered next to job 4 (12). Similarly, for the class B9, the job 4 (14) follows the job 3 (13).
Is registered.

Similarly, in the case of class A8, the delete function 16 deletes jobs 1 (10) and 2 (11) in this order.

By the way, in the present invention, the job 4
Can be registered in the third class A8 and the second class B9 at the same time.
3) is executed first, and then job 4 (1
When 4) is executed, the delete function 16 deletes the job 4 (14) of the class B9 from the class B9 and passes it to the job execution management function 6, and then deletes the job 4 (12) of the class A8 from the class A8. I do.

Similarly, when job 1 (10) and job 2 (11) of class A8 are executed first and job 4 (12) of class A8 is executed first, the delete function 16 By also deleting job 4 (14),
As a result, job 5 (15) becomes job 3 (13)
Will be registered next.

Even when there are a large number of classes, by designating an arbitrary class in the class information 7 of the job, the user can freely combine classes for scheduling.

As described above, the job 1 (1
0) and job 2 (11), and job B (1
If only job 3 is registered and job 4 is registered in class A8 and class B9, job 3 (13) of class B9 is completed faster than job 1 (10) of class A8 and job When 2 (11) is completed, the job 4 of the class A8 is executed.

Thus, the processing of the job scheduling class management system according to one embodiment of the present invention is completed.

The job scheduling class management system according to one embodiment of the present invention allows a user to specify a plurality of job execution classes for a job when submitting the job, thereby reducing the job execution load in each class. This has the effect of being averaged. In other words, there is an effect that it is possible to avoid a load imbalance between classes such that a large amount of jobs are accumulated in a waiting state in other classes even though a certain class is vacant. I have.

[0033]

As described above, the job scheduling class management system and the management method of the present invention are:
By allowing the user to specify a plurality of job execution classes for the job at the time of submitting the job, the load of job execution in each class is averaged, so that the job execution waiting time can be reduced. This has the effect that the job can be executed efficiently.
