Abstract

Systems and methods for implementing communication in a multiprocessor are disclosed. In one exemplary implementation a first processor receives a request to provide a communication resource for an application executing on the first processor to communicate with a remote application. In response to the communication request, the first processor opens a communication resource on a second processor, and implements communication operations between the application executing on the first processor and the remote application using the communication resource on the second processor.

Claims

1. A method of computing, comprising:

receiving, at a first processor, a request to provide a communication resource for an application executing on the first processor to communicate with a remote application;

in response to the communication request, opening a communication resource on a second processor; and

implementing communication operations between the application executing on the first processor and the remote application using the communication resource on the second processor, wherein communication operations between the application executing on the first processor and the remote application are enabled by a demultiplexer module operable on the first processor.

2. The method of claim 1, wherein the communication resource comprises a network socket, and wherein opening a communication resource on a second processor comprises binding the network socket to a network connection managed by the second processor.

3. The method of claim 2, wherein opening a communication resource on the second processor comprises passing a socket descriptor from the second processor to the first processor.

4. The method of claim 3, wherein communication operations between the application executing on the first processor and the remote application using the communication resource on the second processor comprise information about the socket descriptor.

5. The method of claim 1, wherein opening a communication resource on a second processor comprises creating a data table that maps communication requests to an application programming interface method that creates a communication resource on the second processor.

6. The method of claim 1, comprising closing the communication resource on the second processor.

7. The method of claim 1, wherein the first processor comprises a communication server for the remote application.

8. A multiprocessor computing system, comprising:

a first processor and a second processor; and

a demultiplexer module operable on the first processor to manage communication operations between an application executing on the first processor and a remote application using communication resources of the second processor.

9. The multiprocessor computing system of claim 8, wherein the demultiplexer module is configured to open a communication resource on the second processor in response to a communication request for an application executing on the first processor to communicate with a remote application.

10. The multiprocessor computing system of claim 9, wherein the demultiplexer module is configured to create a data table that maps communication requests to an application programming interface method that creates a communication resource on the second processor.

11. The multiprocessor computing system of claim 9, wherein the first processor comprises a communication server for the remote application.

12. The multiprocessor computing system of claim 8, wherein the demultiplexer module is configured to manage inter-processor communication between the first processor and the second processor.

13. The multiprocessor computing system of claim 8, wherein the demultiplexer module is configured to select between communication resources on the first processor and communication resources on the second processor.

14. The multiprocessor computing system of claim 8, wherein the communication resources comprise network sockets.

15. A non-transitory-machine-readable medium that stores machine-readable instructions executable by a first processor to perform multiprocessor communication, the non-transitory, machine-readable medium comprising:

machine-readable instructions that, when executed by the first processor, receive, at a first processor, a request to provide a communication resource for an application executing on the first processor to communicate with a remote application;

machine-readable instructions that, when executed by the first processor, in response to the communication request, open a communication resource on a second processor, wherein the communication resource comprises a network socket, and wherein opening a communication resource on a second processor comprises binding the network socket to a network connection managed by the second processor; and

machine-readable instructions that, when executed by the first processor, implement communication operations between the application executing on the first processor and the remote application using the communication resource on the second processor, wherein communication operations between the application executing on the first processor and the remote application are enabled by a demultiplexer module operable on the first processor.

16. The non-transitory machine-readable medium of claim 15, wherein the machine-readable instructions that, when executed by the first processor, open a communication resource on the second processor comprises machine-readable instructions that, when executed by the first processor, pass a socket descriptor from the second processor to the first processor.

17. The non-transitory machine-readable medium of claim 16, wherein communication operations between the application executing on the first processor and the remote application using the communication resource on the second processor comprise information about the socket descriptor.

18. The non-transitory machine-readable medium of claim 15, wherein opening a communication resource on a second processor comprises creating a data table that maps communication requests to an application programming interface method that creates a communication resource on the second processor.

19. The non-transitory machine-readable medium of claim 15, comprising machine-readable instructions that, when executed by the first processor, close the communication resource on the second processor.

20. The non-transitory machine-readable medium of claim 15, wherein the first processor comprises a communication server for the remote application.
