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.

Allocating acceleration component functionality for supporting services

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.
