Abstract

Systems and methods for network input/output affinity dispatching are provided. Embodiments may include detecting a completion of at least one of a network input operation and a network output operation, and identifying a communication task waiting for the completion. Embodiments may also include adjusting a first affinity queue associated with the communication task, and executing the communication task in accordance with the adjusted first affinity queue.

Claims

1. A method for network input/output affinity dispatching, comprising:

detecting, at a communications processor, a completion of at least one of a network input operation and a network output operation corresponding to a communication task;

identifying, by an interrupt service routine, an application associated with the communication task; and

adjusting, by the interrupt service routine, a first affinity queue associated with the communication task.

2. The method of claim 1, further comprising executing the application in accordance with the adjusted first affinity queue.

3. The method of claim 2, wherein the application comprises one or more instructions for performing a communication operation.

4. The method of claim 1, wherein the step of adjusting the first affinity queue comprises matching the first affinity queue to a second affinity queue associated with the communications processor.

5. The method of claim 1, further comprising interrupting a processor upon detecting the completion of the at least one network operation.

6. A computer program product, comprising:

a non-transitory computer-readable medium comprising code to perform the steps of;

detecting, at a communications processor, a completion of at least one of a network input operation and a network output operation corresponding to a communication task;

identifying, by an interrupt service routine, an application associated with the communication task; and

adjusting, by the interrupt service routine, a first affinity queue associated with the communication task.

7. The computer program product of claim 6, wherein the medium further comprises code to perform the step of executing the application in accordance with the adjusted first affinity queue.

8. The computer program product of claim 7, wherein the application comprises one or more instructions for performing a communication operation.

9. The computer program product of claim 6, wherein the step of adjusting the first affinity queue comprises matching the first affinity queue to a second affinity queue associated with the communications processor.

10. The computer program product of claim 6, further comprising code to perform the step of interrupting a processor upon detecting the completion.

11. An apparatus, comprising:

a memory; and

a processor coupled to the memory, the processor configured to execute the steps of;

detecting, at a communications processor, a completion of at least one of a network input operation and a network output operation corresponding to a communication task;

identifying, by an interrupt service routine, an application associated with the communication task; and

adjusting, by the interrupt service routine, a first affinity queue associated with the communication task.

12. The apparatus of claim 11, wherein the apparatus if further configured to perform the step of executing the application in accordance with the adjusted first affinity queue.

13. The apparatus of claim 12, wherein the application comprises one or more instructions for performing a communication operation

14. The apparatus of claim 11, wherein the step of adjusting the first affinity queue comprises matching the first affinity queue to a second affinity queue associated with the communications processor.

15. The apparatus of claim 11, wherein the processor is further configured to execute the step of interrupting a processor upon detecting the completion.
