摘要： A computer system having a plurality of processing nodes interconnected by a first point-to-point architecture is described. Each processing node has a cache memory associated therewith. A probe filtering unit is operable to receive probes corresponding to memory lines from the processing nodes and to transmit the probes only to selected ones of the processing nodes with reference to probe filtering information. The probe filtering information is representative of states associated with selected ones of the cache memories.

摘要： Improved techniques are provided for detecting and correcting errors and skew in inter-cluster communications within computer systems having a plurality of multi-processor clusters. The local nodes of each cluster include a plurality of processors and an interconnection controller. Intra-cluster links are formed between the local nodes, including the interconnection controller, within a cluster. Inter-cluster links are formed between interconnection controllers of different clusters. Intra-cluster packets may be serialized and encapsulated as inter-cluster packets for transmission on inter-cluster links, preferably with link-layer encapsulation. Each inter-cluster packet may include a sequence identifier and error information computed for that packet. Clock data may be embedded in symbols sent on each bit lane of the inter-cluster links. Copies of transmitted inter-cluster packets may be stored until an acknowledgement is received. The use of inter-cluster packets on an inter-cluster link is preferably transparent to other links and to the protocol layer.

摘要： Techniques and devices are provided for injecting transactions within computer systems having a plurality of multi-processor clusters. Each cluster includes a plurality of nodes, including processors, a service processor and an interconnection controller interconnected by point-to-point intra-cluster links. The processors and the interconnection controller in each cluster make transactions via an intra-cluster transaction protocol. Inter-cluster links are formed between interconnection controllers of different clusters. Each of the processors and the interconnection controller in a cluster has a test interface for communicating with the service processor. The service processor is configured to make an injected transaction according to the intra-cluster transaction protocol via one of the test interfaces. In preferred embodiments, the service processor is configured to make an injected transaction according to the intra-cluster transaction protocol via a test interface of an interconnection controller in the same cluster.
