Abstract: The present invention provides a DRAM/NVM hierarchical heterogeneous memory system with software-hardware cooperative management schemes. In the system, NVM is used as large-capacity main memory, and DRAM is used as a cache to the NVM. Some reserved bits in the data structure of TLB and last-level page table are employed effectively to eliminate hardware costs in the conventional hardware-managed hierarchical memory architecture. The cache management in such a heterogeneous memory system is pushed to the software level. Moreover, the invention is able to reduce memory access latency in case of last-level cache misses. Considering that many applications have relatively poor data locality in big data application environments, the conventional demand-based data fetching policy for DRAM cache can aggravates cache pollution. In the present invention, an utility-based data fetching mechanism is adopted in the DRAM/NVM hierarchical memory system, and it determines whether data in the NVM should be cached in the DRAM according to current DRAM memory utilization and application memory access patterns. It improves the efficiency of the DRAM cache and bandwidth usage between the NVM main memory and the DRAM cache.

Abstract: The present invention relates to a method for temporal knowledge graph reasoning based on distributed attention, comprising: recombining a temporal knowledge graph in a temporal serialization manner, accurately expressing the structural dependencies between time-evolution features and temporal subgraphs, and then extracting historical repetition facts and historical frequency information based on the sparse matrix storing historical subgraph information; assigning, by the query fact, initial first-layer attention to the facts that are historically repeated using an attention mechanism, and then by capturing the latest changes in the historical frequency information, assigning attention reward and punishment of the second-layer attention to the scores of the first-layer attention, respectively, to make attention more adaptable to time-varying features; finally, using the scores of the two layers of attention to make reasoning-based prediction about future events. Compared with traditional prediction methods, the present invention endows learnable distributed attention on different historical timestamps instead of obtaining a fixed embedding representation through an encoder, so that the model has better ability to solve time-varying problems.
