Abstract

A dynamic recovery system comprises a plurality of render nodes each adapted to render data received from a master node. Each of the render nodes is further adapted to receive a render command from the master node indicating a portion of the data to be rendered by the corresponding render node. The system also comprises a control application coupled to each of the render nodes and adapted to automatically reallocate the portion of the data rendered by at least one of the render nodes among a remaining portion of the render nodes in response to an event corresponding to the at least one render node.

Claims

1. A dynamic recovery system, comprising:

a plurality of render nodes each adapted to render data received from a master node, each of the render nodes further adapted to receive a render command from the master node indicating a portion of the data to be rendered by the corresponding render node; and

a control application coupled to each of the render nodes and adapted to automatically reallocate the portion of the data rendered by at least one of the render nodes among a remaining portion of the render nodes in response to an event corresponding to the at least one render node.

2. The system of claim 1, wherein the master node is adapted to poll each of the render nodes to determine an operating status corresponding to each of the render nodes.

3. The system of claim 1, wherein the control application is adapted to designate at least one of the plurality of render nodes as a spare render node.

4. The system of claim 3, wherein the control application is adapted to reallocate to the spare render node the portion of the data rendered by the at least one render node corresponding to the event.

5. The system of claim 1, wherein the plurality of render nodes comprises:

a plurality of active render nodes; and

at least one spare render node.

6. The system of claim 1, wherein the master node is further adapted to transmit the render command to a compositor.

7. The system of claim 1, wherein each render node comprises a converter adapted to generate pixel data.

8. The system of claim 1, wherein the master node is adapted to establish a communication connection to each of the render nodes.

9. The system of claim 1, further comprising a compositor adapted to combine each of the rendered portions of the data relative to each other.

10. The system of claim 1, wherein the event comprises a failure corresponding to one of the render nodes.

11. A method for dynamic recovery, comprising:

transmitting data to each of a plurality of render nodes;

transmitting a render command to each of the render nodes indicating a portion of the data to be rendered by the corresponding render node; and

automatically reallocating the portion of the data rendered by at least one of the render nodes among a remaining portion of the render nodes in response to an event corresponding to the at least one of the render nodes.

12. The method of claim 11, further comprising designating at least one of the plurality of render nodes as a spare render node.

13. The method of claim 11, further comprising automatically updating each render node in response to the reallocation.

14. The method of claim 11, further comprising determining a quantity of available render nodes.

15. The method of claim 14, further comprising transmitting the render command to a compositor.

16. The method of claim 11, wherein reallocating comprises reallocating the portion in response to a failure corresponding to one of the render nodes.

17. The method of claim 11, further comprising combining each of the rendered portions of the data relative to each other.

18. A dynamic recovery system, comprising:

a graphics application adapted to receive graphical data from a master node;

a converter adapted to generate pixel data from the graphical data corresponding to a predetermined display portion; and

a control application adapted to receive a render command modifying the predetermined display portion.

19. The system of claim 18, wherein the control application is adapted to transmit an identification command to the master node.

20. The system of claim 18, wherein the control application is adapted to receive the render command increasing the predetermined display portion.

21. The system of claim 18, wherein the control application is adapted to receive the render command decreasing the predetermined display portion.

22. The system of claim 18, wherein the converter is adapted to transmit the pixel data to the master node.

23. A dynamic recovery system, comprising:

means for transmitting data to each of a plurality of render nodes;

means for transmitting a render command to each of the render nodes, the render command indicating a portion of the data to be rendered by a corresponding render node; and

means for reallocating a portion of the data rendered by at least one of the render nodes among a remaining portion of the render nodes in response to an event corresponding to the at least one render node.

24. The system of claim 23, further comprising means for designating at least one of the plurality of render nodes as a spare render node.

25. The system of claim 23, wherein the means for reallocating comprises means for automatically reallocating the portion of the data.

26. The system of claim 25, further comprising means for combining the rendered data relative to each other.

27. The system of claim 23, further comprising means for transmitting the render command to a compositor.

28. The system of claim 23, further comprising means for establishing a connection to each of the render nodes.

29. The system of claim 23, further comprising means for determining which of the render nodes comprise active render nodes.

30. A dynamic recovery system, comprising:

a graphics application adapted to transmit graphical data to each of a plurality or render nodes; and

a control application adapted to reallocate a display portion assigned to at least one of the render nodes in response to an event corresponding to the at least one of the render nodes.

31. The system of claim 30, wherein the graphics application is further adapted to establish a connection to the render nodes.

32. The system of claim 30, wherein the control application is adapted to designate at least one of the plurality of render nodes as a spare render node.

33. The system of claim 30, wherein the control application is adapted to transmit a render command to a compositor.

34. The system of claim 30, wherein the event comprises a failure corresponding to one of the render nodes.

35. The system of claim 30, wherein the control application is adapted to determine a quantity of active nodes from the plurality of render nodes.

36. The system of claim 30, further comprising a compositor adapted to receive pixel data from at least a portion of the render nodes corresponding to a display portion assigned to each corresponding render node.
