Abstract

A distributed object execution system delegates the allocation and control of computing tasks to intelligent agent applications running on computing resources. User applications can invoke object methods associated with an application interface of the distributed object execution system. The system converts this method invocation into an available computing job with at least one computing tasks. The agents assess computing resources capabilities to perform available computing tasks. Based on these assessments, agents request jobs from a job server, which in turn assigns computing tasks to computing resources based on the job requests received. An agent instantiates a replica of the object and invokes a corresponding method on an associated computing resource. Upon completion of the invoked method, the user application is notified and provided with any method results. While an agent and associated computing resource is processing a method invocation, the user application can perform other activities.

Claims

1. A distributed computing system comprising:

an application interface adapted to receive an invoked object message from a user application, wherein the invoked object message indicates the invocation of a method of an object by the user application;

a control server including a job queue adapted to coordinate the processing of at least one job including at least one task by computing resources;

an object message processing module adapted to convert the received invoked object message into at least one object processing job including at least one object processing task and to add the object processing job and object processing task to the jobs and tasks of the job processing queue;

at least one agent adapted to operate on a computing resource, wherein the agent is adapted to select an object processing job and at least a portion of its object processing tasks in the job queue to be executed by the computing resource; and

an object execution module adapted to operate on the computing resource, to receive an object processing task from the agent, and to execute the method of the object indicated by the invoked object message.

2. The distributed computing system of claim 1, wherein the agent is adapted to select an object processing job based on characteristics of the computing resource and requirements associated with the object processing job.

3. The distributed computing system of claim 1, wherein the object execution module is adapted to instantiate a replica of the object of the user application and to invoke a method of the replica corresponding with the method of the object of the user application.

4. The distributed computing system of claim 3, wherein the object execution module is adapted to deserialize a serialized version of the object of the user application to instantiate a replica of the object.

5. The distributed computing system of claim 4, wherein the serialized version of the object of the user application is communicated with the object execution module via the received invoked object message and the object processing task.

6. The distributed computing system of claim 4, wherein the serialized version of the object is communicated with the object execution module via an object server.

7. The distributed computing system of claim 1, wherein the object execution module is further adapted to communicate a result of the method with the user application via the application interface.

8. The distributed computing system of claim 7, wherein the application interface is adapted to raise an event in the user application in response to receiving the result from the object execution module.

9. The distributed computing system of claim 1, wherein the invoked object message includes a serialized version of the object of the user application.

10. The distributed computing system of claim 1, wherein the invoked object message includes a reference to an object server providing access to the object of the user application.

11. The distributed computing system of claim 1, wherein the invoked object message utilizes the Component Object Model.

12. The distributed computing system of claim 1, wherein the invoked object message utilizes the .NET framework.

13. The distributed computing system of claim 1, wherein the object of the user application is derived from a class provided by the application interface.

14. The distributed computing system of claim 1, wherein the invoked object message includes an execution priority value.

15. The distributed computing system of claim 1, wherein the invoked object message includes requirements for executing the method of the object of the user application.

16. A method of processing objects in a distributed computing system, the method comprising:

receiving an invoked object message from a user application, wherein the invoked object message indicates the invocation of a method of an object by the user application;

converting the received invoked object message into at least one object processing job including at least one object processing task;

adding the object processing job and object processing task to jobs and tasks of a job processing queue;

selecting, by an agent adapted to operate on a computing resource, the object processing job and at least a portion of its object processing tasks in the job queue to be executed by the computing resource; and

receiving, by an object execution module adapted to operate on a computing resource, an object processing task from the agent; and

executing, by the object execution module, the method of the object indicated by the invoked object message.

17. The method of claim 16, further comprising:

selecting, by the agent, the object processing job based on characteristics of the computing resource and requirements associated with the object processing job.

18. The method of claim 16, wherein executing further comprises:

instantiating a replica of the object of the user application; and

invoking a method of the replica corresponding with the method of the object of the user application.

19. The method of claim 18, wherein executing further comprises:

deserializing a serialized version of the object of the user application to instantiate a replica of the object.

20. The method of claim 19, wherein the serialized version of the object of the user application is communicated with the object execution module via the received invoked object message and the object processing task.

21. The method of claim 19, wherein the serialized version of the object is communicated with the object execution module via an object server.

22. The method of claim 16, wherein executing further comprises:

communicating a result of the method with the user application via an application interface.

23. The method of claim 22, wherein communicating further comprises:

raising an event in the user application in response to receiving the result from the object execution module.

24. The method of claim 16, wherein the invoked object message includes a serialized version of the object of the user application.

25. The method of claim 16, wherein the invoked object message includes a reference to an object server providing access to the object of the user application.
