摘要： A system and method are provided for sharing data between a network including one or more network nodes. The network includes a number of individual network nodes and a home network node communicating with one another. The individual network nodes and the home network node include a plurality of processors and memory caches. The memory caches consist of private caches corresponding to individual processors, as well as shared caches which are shared among the plurality of processors of an individual node and accessible by the processors of the other network nodes. Each network node is capable of executing a hierarchy of data requests that originate in the private caches of an individual local network node. If no cache hits occur within the local network node, a conditional request is sent to the home network node to request data through the shared caches of the other network nodes.

摘要： Systems, apparatusses, and methods are disclosed for improving performance of a stride-based prefetcher on an out-of-order central processing unit (CPU). The present disclosure teaches a processor system that employs out-of-order stride prefetch units. The out-of-order stride prefetch units are utilized for issuing prefetches for out-of-order stride access patterns. In one or more embodiments, the out-of-order stride prefetch units examine the offsets between past virtual address (VA) accesses and the directions of the past VA accesses in order to generate an estimate of the underlying VA access stride of the executed program code (PC). In at least one embodiment, the out-of-order stride prefetch units use the estimate of the VA access stride in order to generate a prediction of future VA accesses. In some embodiments, after the out-of-order stride prefetch units have generated the prediction of future VA accesses, the out-of-order stride prefetch units prefetch the predicted future VA accesses.
