Abstract

A method is disclosed that receives a function call at an application program interface. The method selects a first processor of a plurality of processors to execute the function call. The method further executes a first transmit function associated with a bus coupled to the first processor. The first transmit function includes a function parameter associated with the function call.

Claims

1. A method, comprising:

receiving a function call at an application program interface;

selecting a first processor of a plurality of processors to execute the function call; and

executing a first transmit function associated with a bus coupled to the first processor, the first transmit function including a function parameter associated with the function call.

2. The method of claim 1, wherein the transmit function is of a function type associated with transmitting data to the first processor for a function other than execution of a function call.

3. The method of claim 1, wherein the transmit function is a function associated with transmitting data to a processor of a network interface device.

4. The method of claim 1, further comprising:

receiving first information from the first processor based on a second transmit function associated with the bus;

determining that the first information is representative of returned values associated with the first function call; and

communicating the first information to the application program interface.

5. The method of claim 4, wherein the second transmit function is of a function type associated with transmitting data received from a network to a second processor.

6. The method of claim 1, wherein receiving the function call comprises receiving the function call at an application program interface executing at a second processor of the plurality of processors.

7. The method of claim 1, wherein selecting the first processor comprises selecting the first processor based on a relative processor load of the plurality of processors.

8. The method of claim 1, wherein selecting the first processor comprises selecting the first processor based on a function type of the function call.

9. The method of claim 1, wherein selecting the first processor comprises selecting the first processor based on a type of the first processor.

10. The method of claim 1, wherein selecting the first processor comprises selecting the first processor based on an availability of the bus.

11. The method of claim 1, wherein selecting the first processor comprises selecting the first processor based on a latency associated with execution of the function call at the first processor.

12. The method of claim 1, wherein selecting the first processor comprises selecting the first processor based on a bandwidth associated with execution of the function call at the first processor.

13. A method, comprising:

receiving at a first processor via a bus first information associated with a transmit function call at a second processor, the transmit function call associated with the bus; and

in response to determining that the first information is associated with a first function call of an application program interface, executing the first function call at the second processor in response to receiving the first information.

14. The method of claim 13, wherein executing the first function call comprises:

translating the first information to a format for execution at the first processor.

15. The method of claim 13, further comprising:

in response to determining that the first information is not associated with the first function call, transmitting the information to a network.

16. The method of claim 13, wherein executing the first function call comprises determining a return value based on the first function call and further comprising executing a receive function call at the first processor, the receive function call associated with the bus and including the return value.

17. The method of claim 13, further comprising:

in response to executing the first function call, receiving notification of a first event, the first event asynchronous with respect to execution of the first function call; and

transmitting an indication of the notification to the second processor.

18. A computer readable medium storing a computer program comprising a plurality of instructions, the instructions comprising instructions to:

receive a function call at an application program interface;

select a first processor of a plurality of processors to execute the function call; and

execute a first transmit function associated with a bus coupled to the first processor, the first transmit function including a function parameter associated with the function call.

19. The computer readable medium of claim 18, wherein the transmit function is of a function type associated with transmitting data to the first processor for a function other than execution of a function call.

20. The computer readable medium of claim 18, wherein the transmit function is a function associated with transmitting data to a processor of a network interface device.

21. The computer readable medium of claim 18, wherein the instructions further comprise instructions to:

receive first information from the first processor based on a second transmit function associated with the bus;

determine that the first information is representative of returned values associated with the first function call; and

communicate the first information to the application program interface.

22. The computer readable medium of claim 21, wherein the second transmit function is of a function type associated with transmitting data received from a network to a second processor.

23. A computer readable medium storing a computer program comprising a plurality of instructions, the instructions comprising instructions to:

receive at a first processor via a bus first information associated with a transmit function call at a second processor, the transmit function call associated with the bus; and

in response to determining that the first information is associated with a first function call of an application program interface, execute the first function call at the second processor in response to receiving the first information.

24. The computer readable medium of claim 23, wherein the instructions to execute the first function call comprise instructions to translate the first information to a format for execution at the first processor.

25. The computer readable medium of claim 23, wherein the plurality of instructions further comprise instructions to:

in response to determining that the first information is not associated with the first function call, transmitting the information to a network.

26. The computer readable medium of claim 23, wherein the instructions to execute the first function call comprise instructions to determine a return value based on the first function call and wherein the plurality of instructions further comprise instructions to execute a receive function call at the first processor, the receive function call associated with the bus and including the return value.

27. The computer readable medium of claim 23, wherein the plurality of instructions further comprise instructions to:

in response to executing the first function call, receive notification of a first event, the first event asynchronous with respect to execution of the first function call; and

transmit an indication of the notification to the second processor.
