摘要： A non-uniform memory access (NUMA) computer system includes a remote node coupled by a node interconnect to a home node having a home system memory. The remote node includes a local interconnect, a processing unit and at least one cache coupled to the local interconnect, and a node controller coupled between the local interconnect and the node interconnect. The processing unit first issues, on the local interconnect, a read-type request targeting data resident in the home system memory with a flag in the read-type request set to a first state to indicate only local servicing of the read-type request. In response to inability to service the read-type request locally in the remote node, the processing unit reissues the read-type request with the flag set to a second state to instruct the node controller to transmit the read-type request to the home node. The node controller, which includes a plurality of queues, preferably does not queue the read-type request until receipt of the reissued read-type request with the flag set to the second state.

摘要： A processor includes execution resources, data storage, and an instruction sequencing unit, coupled to the execution resources and the data storage, that supplies instructions within the data storage to the execution resources. At least one of the execution resources, the data storage, and the instruction sequencing unit is implemented with a plurality of hardware partitions of like function for processing a respective one of a plurality of data streams. If an error is detected in a particular hardware partition, the data stream assigned to that hardware partition is reassigned to another of the plurality of hardware partitions, thus preventing an error in one of the hardware partitions from resulting in a catastrophic failure.

摘要： A method of providing programmable congruence classes in a cache used by a processor of a computer system is disclosed. Program instructions are loaded in the processor for modifying original addresses of memory blocks in a memory device to produce encoded addresses. A plurality of cache congruence classes is then defined using a mapping function which operates on the encoded addresses, such that the program instructions may be used to arbitrarily assign a given one of the original addresses to a particular one of the cache congruence classes. The program instructions can modify the original addresses by setting a plurality of programmable fields. Application software may provide the program instructions, wherein congruence classes are programmed based on a particular procedure of the application software which is running on the processor, that might otherwise run with excessive "striding" of the cache. Alternatively, operating-system software may monitor allocation of memory blocks in the cache and provides the program instructions to modify the original addresses based on the allocation of the memory blocks, to lessen striding.

摘要： A method of providing programmable congruence classes in a cache used by a processor of a computer system is disclosed. A logic unit is connected to the cache for modifying original addresses of memory blocks in a memory device to produce encoded addresses. A plurality of cache congruence classes are then defined using a mapping function which operates on the encoded addresses, such that the logic unit may be used to arbitrarily assign a given one of the original addresses to a particular one of the cache congruence classes. The logic unit can modify the original addresses by setting a plurality of programmable fields. The logic unit also can collect information on cache misses, and modify the original addresses in response to the cache miss information. In this manner, a procedure running on the processor and allocating memory blocks to the cache such that the original addresses, if applied to the mapping function, would result in striding of the cache, runs more efficiently by using the encoded addresses to result in less striding of the cache.
