Abstract

The present invention extends to methods, systems, and computer program products for reconfiguring an acceleration component among interconnected acceleration components. Aspects of the invention facilitate reconfiguring an acceleration component among interconnected acceleration components using a higher-level software service. A manager or controller isolates an acceleration component by sending a message to one or more neighbor acceleration components instructing the one or more neighbor acceleration components to stop accepting communication from the acceleration component. The manager or controller can then shut down an application layer at the acceleration component for at least partial reconfiguration and closes input/output (I/O) portions. After reconfiguration completes, communication between the acceleration component and the one or more neighbor acceleration components can resume.

Claims

1. A method for reconfiguring an acceleration component, the method comprising:

detecting a condition in a role at an acceleration component included in a plurality of acceleration components in a hardware acceleration plane, the role linked together with an interoperating role at a neighbor acceleration component included in the plurality of acceleration components to compose a graph wherein each role performs a different part of service acceleration;

sending a command to the graph to quiesce the graph;

receive an indication that the graph is quiesced;

subsequent to receiving the indication, isolating the acceleration component from the neighbor acceleration component in the graph by sending a halt command to the neighbor acceleration component;

receiving another indication from the neighbor acceleration component that the neighbor acceleration component is halted;

reconfiguring the role at the acceleration component;

sending an activate command to the neighbor acceleration component;

receiving a further indication from the neighbor acceleration component that the neighbor acceleration component is activated; and

subsequent to receiving the further indication, send another command to the graph to reactivate the graph.

2. The method of claim 1, further comprising determining that it is appropriate to reconfigure a role based on the detected condition.

3. The method of claim 1, further comprising:

isolating the acceleration component from another neighbor acceleration component in the graph by sending another halt command to the other neighbor acceleration component; and

receiving an additional indication from the other neighbor acceleration component that the other neighbor acceleration component is halted.

4. The method of claim 1, wherein reconfiguring the role at the acceleration component comprises:

sending a reconfiguration command to the acceleration component; and

receiving an indication from the acceleration component that the role has been reconfigured.

5. The method of claim 1, wherein reconfiguring the role at the acceleration component comprises loading an image file at the acceleration component.

6. The method of claim 1, wherein reconfiguring the role at the acceleration component comprises reconfiguring the role at a Field Programmable Gate Array (FPGA).

7. The method of claim 1, wherein the graph comprises a graph providing service acceleration for a service selected from among:

document ranking, data encryption, data compression, speech translation, computer vision, or machine learning.

8. A computer program product for implementing a method for reconfiguring an acceleration component, the computer program product comprising one or more computer storage devices having stored thereon computer-executable instructions that, in response to execution at a processor, cause the method to be performed, comprising:

detect a condition in a role at an acceleration component included in a plurality of acceleration components in a hardware acceleration plane, the role linked together with an interoperating role at a neighbor acceleration component included in the plurality of acceleration components to compose a graph wherein each role performs a different part of service acceleration;

send a command to the graph to quiesce the graph;

receive an indication that the graph is quiesced;

subsequent to receiving the indication, isolate the acceleration component from the neighbor acceleration component in the graph by sending a halt command to the neighbor acceleration component;

receive another indication from the neighbor acceleration component that the neighbor acceleration component is halted;

reconfigure the role at the acceleration component;

send an activate command to the neighbor acceleration component;

receive a further indication from the neighbor acceleration component that the neighbor acceleration component is activated; and

subsequent to receiving the further indication, send another command to the graph to reactivate the graph.

9. The computer program product of claim 8, wherein computer-executable instructions that, in response to execution, reconfigure the role at the acceleration component comprise computer-executable instructions that, when executed, load an image file at the acceleration component.

10. The computer program product of claim 8, wherein computer-executable instructions that, in response to execution, reconfigure the role at the acceleration component comprise computer-executable instructions that, in response to execution, reconfigure the role at a Field Programmable Gate Array (FPGA).

11. The computer program product of claim 8, wherein each role performs a different part of service acceleration comprises each role performing a different part of service acceleration for a service selected from among:

document ranking, data encryption, data compression, speech translation, computer vision, or machine learning.

12. The computer program product of claim 8, wherein the hardware acceleration plane comprises a configurable fabric of Field Programmable Gate Arrays (FPGAs).

13. A system, the system including:
