Abstract

To improve the task processing speed, when a large number of small-sized tasks are executed. When a task is completed, the event check means checks whether or not an event of the same kind as that of the event which created the completed task is registered in the event storing unit. When it is not registered, the resources which have been used by the completed task and should be rewritten are returned from the task resource management means to the task resource storing unit. When an event of the other kinds is registered in the event storing unit, the task creation and resource acquisition are repeated. When an event of the same kind is registered, the same task is continuously processed without release and re-acquisition of resource.

Claims

1. A task processing system, comprising:

a storage for storing an event identifier for each event of a plurality of events, wherein said event identifiers comprise a first event identifier corresponding to a first task;

a task control device for creating a task based on at least one of said plurality of events, wherein said task control device executes a search for said first event identifier to create a second task the same as said first task; and

a task processing device for executing a plurality of tasks, wherein the plurality of tasks comprise said first task and said second task,

whereupon completing said first task of said plurality of tasks, said task processing device initiates a search for a second event identifier, and if said second event identifier is the same as said first event identifier corresponding to said first task, then processes said second task corresponding to said second event identifier using a resource used by said first task.

2. The task processing system according to claim 1, wherein a first resource used by said first task, which is completed, is released from said task processing device toward said storage, when said second event identifier is not the same as said first event identifier.

3. The task processing system according to claim 2, wherein said first resource is released from said storage, when said first resource is transferred from said storage via said task control device to said task processing device.

4. The task processing system according to claim 1, whereupon completing said first task, said processing device deletes said first event identifier from said storage.

5. The task processing system according to claim 1, wherein said storage includes a task resource storing unit.

6. The task processing system according to claim 1, wherein said task control device includes an event checker that identifies said event identifier for each task of said plurality of tasks.

7. The task processing system according to claim 1, wherein said task control device includes a task creator that creates a task corresponding to said event identifier.

8. The task processing system according to claim 1, wherein said task control device includes a task resource manager that transfers a task resource, corresponding to said event identifier, to said task processing unit.

9. A task system, comprising:

a storage for storing an event identifier for each task of a plurality of tasks, wherein said event identifiers comprise a first event identifier corresponding to a first task; and

a task processing device for executing a plurality of tasks; and

a task control device, including;

an event checker that identifies said event identifier for each task of said plurality of tasks;

a task creator that creates a task corresponding to an identified event identifier; and

a task resource manager that transfers a task resource, corresponding to said task, to said task processing device,

wherein said task control device further executes a search for said first event identifier to create a second task the same as said first task;

whereupon completing said first task, said task processing device initiates a search for a second event identifier that corresponds to said second task and if said second event identifier is the same as said first event identifier, then processes said second task using a resource used by said first task.

10. The task system according to claim 9, whereupon completing said first task, said task processing device deletes said first event identifier from said storage.

11. The task system according to claim 9, wherein said storage comprises a task resource storing unit that stores a plurality of task resources corresponding to said plurality of tasks.

12. A method of processing a task, comprising:

storing a first event identifier corresponding to a first event and a second event identifier corresponding to a second event;

creating a first task corresponding to said first event;

processing said first task with a first task resource;

initiating a search for said first event identifier to create a second task the same as the first task;

determining whether said a first event identifier corresponding to said first task is the same as said second event identifier corresponding to a second task;

processing said second task with said first task resource, if said second event identifier is the same as said first event identifier; and

acquiring a second task resource and processing said second task using said second task resource, if said second event identifier is not the same as said first event identifier.

13. The method of claim 12, further comprising deleting said first event identifier from an event storing unit upon completion of said processing of said first task.
