Abstract

A system, method and computer-readable media for managing a compute environment are disclosed. The method includes importing identity information from an identity manager into a module performs workload management and scheduling for a compute environment and, unless a conflict exists, modifying the behavior of the workload management and scheduling module to incorporate the imported identity information such that access to and use of the compute environment occurs according to the imported identity information. The compute environment may be a cluster or a grid wherein multiple compute environments communicate with multiple identity managers.

Claims

1. A method comprising:

importing identity information from an identity manager into a management module that performs workload management and scheduling, at a first time, of workload for consumption of resources in a multi-server compute environment at a second time, which is later than the first time, wherein the identity information comprises credentials associated with at least one of users, groups of users, accounts, projects, classes, queues and qualities of service; and

modifying a behavior of the management module to incorporate the identity information such that a scheduling decision for resources in the multi-server compute environment is based at least in part on the identity information, wherein if a conflict exists between the identity information and local information, resolving the conflict.

2. The method of claim 1, wherein the identity manager is at least one of:

a text file, a database or a service.

3. The method of claim 1, wherein the management module further comprises at least one of a resource manager, a grid manager, a cluster scheduler and a workload manager.

4. The method of claim 1, wherein importing identity information from the identity manager further comprises importing identity information from a plurality of identity managers.

5. The method of claim 4, wherein each identity manager of the plurality of identity managers has a different type of information.

6. The method of claim 1, wherein the identity manager further comprises information associated with at least one of default credential associations and credential specification constraints.

7. The method of claim 6, wherein the default credential associations define credentials for users where no specified constraints exist and credential specification constraints further comprise constraints related to at least one of:

a service level agreement, priority information, usage limit information, fairshare targets, service guarantees, resource constraints, usage statistics, contact information and billing information.

8. The method of claim 1, wherein the identity manager is associated with a service that receives identity information from any location including the management module.

9. The method of claim 8, wherein the identity manager receives identity information from at least one of:

the Internet, administrator input, another identity manager, and another management module.

10. The method of claim 1, wherein the management module obtains a global view of users and groups based on the identity information and from locally obtained identity information.

11. The method of claim 1, wherein the identity information from the identity manager into the management module comprises a subset of the identity information in the identity manager which is relevant to the multi-server compute environment managed by the management module.

12. The method of claim 1, further comprising:

exporting from the management module locally obtained identity information to the identity manager.

13. The method of claim 12, wherein exporting the locally obtained identity information further comprises periodically exporting the locally obtained identity information as new identity information is discovered by the management module.

14. The method of claim 1, wherein a plurality of identity managers and a plurality of management modules import and export identity information.

15. The method of claim 1, wherein if the conflict is resolved in favor of the local identity information, then the management module manages access to and use of the multi-server compute environment according to the local identity information.

16. The method of claim 1, wherein the identity manager interfaces with the management module according to a generic interface.

17. A system for managing a compute environment, the system comprising:

a processor; and

a non-transitory computer-readable storage medium storing instructions, which, when executed by the processor, cause the processor to perform operations comprising;

importing identity information from an identity manager into a management module that performs workload management and scheduling, at a first time, of workload for consumption of resources in a multi-server compute environment at a second time, which is later than the first time, wherein the identity information comprises credentials associated with at least one of users, groups of users, accounts, projects, classes, queues and qualities of service; and

modifying a behavior of the management module to incorporate the identity information such that a scheduling decision for resources in the multi-server compute environment is based at least in part on the identity information, wherein if a conflict exists between the identity information and local information, resolving the conflict.

18. A non-transitory computer-readable medium storing instructions which, when executed by processor, cause the processor to perform operations comprising:

importing identity information from an identity manager into a management module that performs workload management and scheduling, at a first time, of workload for consumption of resources in a multi-server compute environment, at a second time, which is later than the first time, wherein the identity information comprises credentials associated with at least one of users, groups of users, accounts, projects, classes, queues and qualities of service; and

modifying a behavior of the management module to incorporate the identity information such that a scheduling decision, at the first time, for resources in the multi-server compute environment is based at least in part on the identity information, wherein if a conflict exists between the identity information and local information, resolving the conflict.
