Patent number: 11099906Abstract: A service mapping component (SMC) is described herein for processing requests by instances of tenant functionality that execute on software-driven host components (or some other components) in a data processing system. The SMC is configured to apply at least one rule to determine whether a service requested by an instance of tenant functionality is to be satisfied by at least one of: a local host component, a local hardware acceleration component which is locally coupled to the local host component, and/or at least one remote hardware acceleration component that is indirectly accessible to the local host component via the local hardware acceleration component. In performing its analysis, the SMC can take into account various factors, such as whether or not the service corresponds to a line-rate service, latency-related considerations, security-related considerations, and so on.Type: GrantFiled: September 11, 2018Date of Patent: August 24, 2021Assignee: Microsoft Technology Licensing, LLCInventors: Derek T. Chiou, Sitaram V. Lanka, Douglas C. Burger

Patent number: 10977104Abstract: Aspects extend to methods, systems, and computer program products for partially reconfiguring acceleration components. Partial reconfiguration can be implemented for any of a variety of reasons, including to address an error in functionality at the acceleration component or to update functionality at the acceleration component. During partial reconfiguration, connectivity can be maintained for any other functionality at the acceleration component untouched by the partial reconfiguration. Partial reconfiguration is more efficient to deploy than full reconfiguration of an acceleration component.Type: GrantFiled: January 25, 2019Date of Patent: April 13, 2021Assignee: Microsoft Technology Licensing, LLCInventors: Derek T. Chiou, Sitaram V. Lanka, Adrian M. Caulfield, Andrew R. Putnam, Douglas C. Burger

Patent number: 10819657Abstract: Aspects extend to methods, systems, and computer program products for allocating acceleration component functionality for supporting services. A service manager uses a finite number of acceleration components to accelerate services. Acceleration components can be allocated in a manner that balances load in a hardware acceleration plane, minimizes role switching, and adapts to demand changes. When role switching is appropriate, less extensive mechanisms (e.g., based on configuration data versus image files) can be used to switch roles to the extent possible.Type: GrantFiled: February 25, 2019Date of Patent: October 27, 2020Assignee: Microsoft Technology Licensing, LLCInventors: Douglas C. Burger, Andrew R. Putnam, Stephen F. Heil, Michael David Haselman, Sitaram V. Lanka, Yi Xiao

Patent number: 10511478Abstract: Aspects extend to methods, systems, and computer program products for changing between different roles at acceleration components. Changing roles at an acceleration component can be facilitated without loading an image file to configure or partially reconfigure the acceleration component. At configuration time, an acceleration component can be configured with a framework and a plurality of selectable roles. The framework also provides a mechanism for loading different selectable roles for execution at the acceleration component (e.g., the framework can include a superset of instructions for providing any of a plurality of different roles). The framework can receive requests for specified roles from other components and switch to a subset of instructions for the specified roles. Switching between subsets of instructions at an acceleration component is a lower overhead operation relative to reconfiguring or partially reconfiguring an acceleration component by loading an image file.Type: GrantFiled: June 26, 2015Date of Patent: December 17, 2019Assignee: Microsoft Technology Licensing, LLCInventors: Andrew R. Putnam, Douglas C. Burger, Michael David Haselman, Stephen F. Heil, Yi Xiao, Sitaram V. Lanka

Patent number: 10027543Abstract: 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.Type: GrantFiled: June 26, 2015Date of Patent: July 17, 2018Assignee: Microsoft Technology Licensing, LLCInventors: Sitaram V.

Patent number: 9983938Abstract: Aspects extend to methods, systems, and computer program products for locally restoring functionality at acceleration components. A role can be locally restored at an acceleration component when an error is self-detected at the acceleration component (e.g., by local monitoring logic). Locally restoring a role can include resetting internal state (application logic) of the acceleration component providing the role. Self-detection of errors and local restoration of a role is less resource intensive and more efficient than using external components (e.g., high-level services) to restore functionality at an acceleration component and/or to reset an entire graph. Monitoring logic at multiple acceleration components can locally reset roles in parallel to restore legitimate behavior of a graph.Type: GrantFiled: June 26, 2015Date of Patent: May 29, 2018Assignee: Microsoft Technology Licensing, LLCInventors: Stephen F.

Patent number: 9652327Abstract: Aspects extend to methods, systems, and computer program products for reassigning service functionality between acceleration components. Reassigning service functionality can be used to recover service acceleration for a service. Service acceleration can operate improperly due to performance degradation at an acceleration component. A role at the acceleration component having degraded performance can be assigned to another acceleration component to restore service acceleration for the service.Type: GrantFiled: June 26, 2015Date of Patent: May 16, 2017Assignee: Microsoft Technology Licensing, LLCInventors: Stephen F.
