Abstract
Description
technical field
[0001] The invention relates to the field of computer technology, in particular to a method for node control chip directory Cache in a CC-NUMA (Cache Coherent Non-Uniform Memory Access) system. Background technique
[0002] As the application of high-performance computing becomes more and more extensive and in-depth, the architecture and implementation of high-performance computers are facing higher and higher requirements, and the CC-NUMA structure is one of the important architectures. The construction of a large-scale CC-NUMA system is constrained by many factors, among which the Cache coherence protocol is the key factor restricting the scalability of the system. In order to solve this problem, in addition to designing an effective protocol, researching the scalable directory structure and efficient directory storage access mechanism in the system can ensure the efficient implementation of the directory-based Cache consistency protocol.
