Abstract

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.
