摘要： A data processing system, method, and computer-usable medium for recovering from a hang condition in a data processing system. The data processing system includes a collection of coupled processing units. The processing units include a collection of processing unit components such as, two or more processing cores, and a cache array, a processor core master, a cache snooper, and a local hang manager. The local hang manager determines whether at least one component out of the collection of processing unit components has entered into a hang condition. If the local hang manager determines at least one component has entered into a hang condition, a throttling manager throttles the performance of the processing unit in an attempt to break the at least one component out of the hang condition.

摘要： A method and apparatus for performing data prefetch in a multiprocessor system are disclosed. The multiprocessor system includes multiple processors, each having a cache memory. The cache memory is subdivided into multiple slices. A group of prefetch requests is initially issued by a requesting processor in the multiprocessor system. Each prefetch request is intended for one of the respective slices of the cache memory of the requesting processor. In response to the prefetch requests being missed in the cache memory of the requesting processor, the prefetch requests are merged into one combined prefetch request. The combined prefetch request is then sent to the cache memories of all the non-requesting processors within the multiprocessor system. In response to a combined clean response from the cache memories of all the non-requesting processors, data are then obtained for the combined prefetch request from a system memory.

摘要： A data processing system includes a plurality of processing units coupled by a plurality of communication links for point-to-point communication such that at least some of the communication between multiple different ones of the processing units is transmitted via intermediate processing units among the plurality of processing units. The communication includes operations having a request and a combined response representing a system response to the request. At least each intermediate processing unit includes one or more masters that initiate first operations, a snooper that receives at least second operations initiated by at least one other of the plurality of processing units, a physical queue that stores master tags of first operations initiated by the one or more masters within that processing unit, and a ticketing mechanism that assigns to second operations observed at the intermediate processing unit a ticket number indicating an order of observation with respect to other second operations observed by the intermediate processing unit. The ticketing mechanism provides the ticket number assigned to an operation to the snooper for processing with a combined response of the operation.
