Abstract

In brief, the invention provides a method and system for admission control in a grid computing environment. When a user request for a global session is received from a submission node, applications to be launched through the global session are identified, and resource requirements are determined. A execution node is then allocated, and the global session is established between the execution node and the submission node. A user then requests an application session through the established global session, and the application session is established with the execution node.

Claims

1. A method of admission control for admitting global and application session requests in a grid computing system, the method comprising:

receiving a user request for a global session from a user at a submission node, wherein the submission node includes a computing system local to the user;

receiving from the user a list of applications to be launched through the global session;

identifying the applications as a set of allowed applications by consulting authorization policies specifying a list of allowed applications;

determining resource requirements for the identified applications;

allocating an execution node satisfying the resource requirements, wherein the allocated execution node includes a computing system remote from the user;

establishing the global session between the allocated execution node and the submission node, wherein the global session creates a network connection between the submission node and the allocated execution node allowing the submission node to utilize resources associated with the allocated execution node;

receiving a user request for an application session through the established global session; and

establishing the application session with the allocated execution node, wherein the application session allows the user to interact directly with one or more applications running on the execution node.

2. A method of admission control in a grid computing system according to claim 1, further comprising receiving at a node for managing the allocated execution node the user request for a global session, determining by the node for managing the allocated execution node whether to allow an establishment of the global session, receiving at the allocated execution node the user request for an application session, and determining by the allocated execution node whether to allow an establishment of the application session.

3. A method of admission control in a grid computing system according to claim 1, wherein the step of determining resource requirements includes consulting an application profile, the application profile including an identification of resource requirements for an application, including processor requirements and network bandwidth requirements.

4. A method of admission control in a grid computing system according to claim 1, wherein the application session is a graphical interactive session created by exporting the desktop environment of the execution node to the submission node.

5. A method of admission control in a grid computing system according to claim 1, wherein multiple application sessions are launched in the global session.

6. A method of admission control in a grid computing system according to claim 1, wherein user interaction is controlled through one or more management agents, the one or more management agents being driven by authorization policies.

7. A method of admission control in a grid computing system according to claim 1, further comprising:

generating a first admission control decision, the first admission control decision regarding the admission of the global session to the execution node; and

generating a second admission control decision, the second admission control decision regarding the admission of the application session to the execution node.

8. A system for admission control for admitting global and application session requests in a grid computing environment, the system including one or more processors, one or more memories coupled to the one or more processors, and program instructions stored in the one or more memories, the one or more processors being operable to execute the program instructions, the program instructions comprising instructions for:

receiving at a node for managing execution nodes a user request for a global session from a user at a submission node, wherein the submission node includes a computing system local to the user;

identifying applications to be launched through the global session, wherein identifying applications includes identifying applications as a set of allowed applications by consulting authorization policies specifying a list of allowed applications after receiving from the user a list of the identified applications;

determining resource requirements for the requested global session;

determining by the node for managing the execution nodes whether to allow an establishment of the global session;

allocating an execution node satisfying the resource requirements, wherein the allocated execution node includes a computing system remote from the user;

establishing the global session between the allocated execution node and the submission node, wherein the global session creates a network connection between the submission node and the allocated execution node allowing the submission node to utilize resources associated with the allocated execution node;

receiving at the allocated execution node a user request for an application session;

determining by the allocated execution node whether to allow an establishment of the application session; and

establishing the application session with the allocated execution node, wherein the application session allows the user to interact directly with one or more applications running on the allocated execution node.

9. A system for admission control in a grid computing environment according to claim 8, further comprising an applications profiles repository which provides information concerning resource requirements for individual applications.

10. A system for admission control in a grid computing environment according to claim 8, further comprising a grid scheduler which performs the step of allocating resources for the global session.

11. A system for admission control in a grid computing environment according to claim 8, further comprising one or more management agents, the one or more management agents being driven by authorization policies.

12. A system for admission control for admitting global and application session requests in a grid computing environment, the system comprising:
