Abstract

Methods and apparatus, including computer program products, for control interfaces for distributed system applications. A method includes, at an application deployed on a first computing system in a grid computing environment, monitoring a communication channel connecting the first computing system to a second computing system, receiving a command over the communication channel from the second computing system, and in response to the received command, generating a descriptor file including descriptions of one or more actions to be performed by the second computing system in order to move the application from the first computing system to a third computing system.

Claims

1. A method comprising:

at an application deployed on a first computing system in a grid computing environment,

monitoring a communication channel connecting the first computing system with a second computing system;

receiving a command over the communication channel from the second computing system; and

in response to the received command, generating a descriptor file including descriptions of one or more actions to be performed by the second computing system in order to move the application from the first computing system to a third computing system.

2. The method of claim 1, further comprising:

terminating execution of the application.

3. The method of claim 1, further comprising:

at the second computing system,

receiving the descriptor file including action descriptions; and

using the action descriptions to move the application from the first computing system to the third computing system.

4. The method of claim 3, further comprising:

at the third computing system, starting execution of the application.

5. The method of claim 1, wherein the descriptor file is an extended markup language (XML) file.

6. The method of claim 1, wherein the action descriptions include at least one of:

a set of command line parameters to be passed to the application at startup to initiate application execution at the third computing system; and

a set of files associated with the application to be copied to the third computing system.

7. The method of claim 1, wherein the application is a mobile agent and the first descriptor file includes an empty list.

8. The method of claim 1, wherein:

the first computing system is a first computational resource;

the second computing system is a grid resource manager; and

the third computing system is a second computational resource.

9. A method comprising:

at an application deployed on a first computing system in a grid computing environment,

monitoring a communication channel connecting the first computing system with a second computing system;

receiving a command over the communication channel from the second computing system;

in response to the received command, generating a descriptor file including descriptions of one or more actions to be performed by the second computing system in order to start the application; and

terminating execution of the application.

10. The method of claim 9, further comprising:

at the second computing system,

receiving the descriptor file including action descriptions; and

using the action descriptions to start the application at the first computing system.

11. The method of claim 9, wherein the descriptor file is an extended markup language (XML) file.

12. The method of claim 9, wherein the action descriptions include at least one of:

a set of command line parameters to be passed to the application at startup to initiate application execution; and

a set of log files.

13. The method of claim 9, wherein:

the first computing system is a computational resource; and

the second computing system is a grid resource manager.

14. A computer program product, tangibly embodied in an information carrier, for control interfaces for distributed system applications, the computer program product being operable to cause data processing apparatus to:

at an application deployed on a first computing system in a grid computing environment, monitor a communication channel connecting the first computing system to a second computing system;

receive a command over the communication channel from the second computing system; and

in response to the received command, generate a descriptor file including descriptions of one or more actions to be performed by the second computing system in order to move the application from the first computing system to a third computing system.

15. The computer program product of claim 14, further operable to:

terminate execution of the application.

16. The computer program product of claim 14, further operable to:

at the second computing system, receive the descriptor file including action descriptions; and

use the action descriptions to move the application from the first computing system to the third computing system.

17. The computer program product of claim 16, further operable to at the third computing system in the grid computing environment, start execution of the application.

18. The computer program product of claim 14, wherein the descriptor file is an extended markup language (XML) file.

19. The computer program product of claim 14, wherein the action descriptions include at least one of:

a set of command line parameters to be passed to the application at startup to initiate application execution at the third computing system; and

a set of files associated with the application to be copied to the third computing system.

20. The computer program product of claim 14, wherein the application is a mobile agent and the first descriptor file includes an empty list.
