Abstract

Methods, compute nodes, and computer program products are provided for heuristic status polling of a component in a computing system. Embodiments include receiving, by a polling module from a requesting application, a status request requesting status of a component; determining, by the polling module, whether an activity history for the component satisfies heuristic polling criteria; polling, by the polling module, the component for status if the activity history for the component satisfies the heuristic polling criteria; and not polling, by the polling module, the component for status if the activity history for the component does not satisfy the heuristic criteria.

Claims

1. A computer-implemented method for heuristic status polling of a component in a computing system, the method comprising:

receiving, by a polling module from a requesting application a status request requesting status of a component;

determining, by the polling module, whether an activity history for the component satisfies heuristic polling criteria;

polling, by the polling module, the component for status if the activity history for the component satisfies the heuristic polling criteria; and

not polling, by the polling module, the component for status if the activity history for the component does not satisfy the heuristic criteria.

2. The method of claim 1 wherein polling, by the polling module, the component for status if the activity history for the component satisfies the heuristic polling criteria further comprises updating the activity history for the component.

3. The method of claim 1 wherein polling, by the polling module, the component for status if the activity history for the component satisfies the heuristic polling criteria further comprises updating the heuristic polling criteria.

4. The method of claim 1 wherein not polling, by the polling module, the component for status if the activity history for the component does not satisfy the heuristic polling criteria further comprises updating the heuristic polling criteria.

5. The method of claim 1 further comprising periodically updating, by the polling module, the heuristic polling criteria in dependence upon the activity history.

6. The method of claim 1 wherein the polling module is comprised in a compute node of a parallel computer, the parallel computer comprising a plurality of compute nodes connected for data communications through a data communications network.

7. A compute node capable of heuristic status polling of a component in a computing system, the compute node a computer processor, computer memory operatively coupled to the computer processor, the computer memory having disposed within it computer program instructions capable of:

receiving, from a requesting application, a status request requesting status of a component;

determining whether an activity history for the component satisfies heuristic polling criteria;

polling the component for status if the activity history for the component satisfies the heuristic polling criteria; and

not polling the component for status if the activity history for the component does not satisfy the heuristic criteria.

8. The compute node of claim 7 wherein computer program instructions capable of polling the component for status if the activity history for the component satisfies the heuristic polling criteria further comprise computer program instructions capable of updating the activity history for the component.

9. The compute node of claim 7 wherein computer program instructions capable of polling the component for status if the activity history for the component satisfies the heuristic polling criteria further comprise computer program instructions capable of updating the heuristic polling criteria.

10. The compute node of claim 7 wherein computer program instructions capable of not polling the component for status if the activity history for the component does not satisfy the heuristic polling criteria further comprise computer program instructions capable of updating the heuristic polling criteria.

11. The compute node of claim 7 wherein the computer memory also has disposed within it computer program instructions capable of periodically updating, by the polling module, the heuristic polling criteria in dependence upon the activity history.

12. The compute node of claim 7 wherein the compute node in a parallel computer, the parallel computer comprising a plurality of compute nodes connected for data communications through a data communications network.

13. A computer program product for heuristic status polling of a component in a computing system, the computer program product disposed upon a computer readable medium, the computer program product comprising computer program instructions capable of:

receiving, from a requesting application, a status request requesting status of a component;

determining whether an activity history for the component satisfies heuristic polling criteria;

polling the component for status if the activity history for the component satisfies the heuristic polling criteria; and

not polling the component for status if the activity history for the component does not satisfy the heuristic criteria.

14. The computer program product of claim 13 wherein computer program instructions capable of polling the component for status if the activity history for the component satisfies the heuristic polling criteria further comprise computer program instructions capable of updating the activity history for the component.

15. The computer program product of claim 13 wherein computer program instructions capable of polling the component for status if the activity history for the component satisfies the heuristic polling criteria further comprise computer program instructions capable of updating the heuristic polling criteria.

16. The computer program product of claim 13 wherein computer program instructions capable of not polling the component for status if the activity history for the component does not satisfy the heuristic polling criteria further comprise computer program instructions capable of updating the heuristic polling criteria.

17. The computer program product of claim 13 further comprising computer program instructions capable of periodically updating, by the polling module, the heuristic polling criteria in dependence upon the activity history.

18. The computer program product of claim 13 wherein the computer program product is disposed in a compute node in a parallel computer, the parallel computer comprising a plurality of compute nodes connected for data communications through a data communications network.

19. The computer program product of claim 13 wherein the computer readable medium comprises a recordable medium.

20. The computer program product of claim 13 wherein the computer readable medium comprises a transmission medium.
