The method effectively reduces a possibility of a breakdown of the system caused by accumulation of the error bits in the directory memory of the CC-NUMA system. The method comprises: when a quantity of bits of a correctable error of a directory stored in a directory memory of the node is greater than a preset threshold, controlling all processors in the CC-NUMA system to write dirty data in a corresponding cache back to a corresponding main memory, flush the dirty data, and directly flush clean data in the corresponding cache; and controlling the CC-NUMA system to enter a quiescent state, clearing a record stored in the directory memory to zero, and controlling, after the zero clearing is completed, the CC-NUMA system to exit the quiescent state."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for processing error directory of node in CC-NUMA system, and node","description":"A method for processing an error directory of a node in a cache coherence non-uniform memory access (CC-NUMA) system and a node are provided.
