Abstract
Each of the processing devices stores an event vector, which is updated when certain events (e.g. memory errors, overtemperature events) occur on the device. Different elements of the vector correspond to different types of events. When an event of a given type occurs on one device, the update to the event vector on that device is propagated to other devices in the system. Those other devices, in response, update the corresponding element in their own event vector to indicate that an event of that given type has occurred in the system. In this way, events are aggregated between the different devices using the event vector. The event vector is considered to be a global event vector, since its elements indicate whether certain events have occurred across the entire system, and the vector is consistent across the system.
