Abstract

The invention provides a persistent internal memory transaction processing cache management method and device. The method comprises the steps of reading, by a transaction, original data from a nonvolatile internal memory to a processor for caching before the start of the transaction, and executing the transaction by the processor; allocating, by the transaction, a space for produced new data during the execution of the transaction, and adopting a cache stealing write-back technique to allow persisting of un-submitted data; forcibly persisting transaction data or state to the nonvolatile internal memory during the submission or interruption of the transaction; writing back the transaction data to an original data address after the transaction data or state has been persisted to the nonvolatile internal memory, and adopting a cache non-forced write-back technique to not forcibly persist submitted data to the nonvolatile internal memory; periodically persisting, by the transaction, cache data to the nonvolatile internal memory by means of forced integral brush-back; performing fault recovery processing on the transaction data when a fault occurs in a system. By adopting the method, the data replication and data persisting frequency in the persistent internal memory can be reduced.

Description

technical field [0001] The invention relates to the technical field of non-volatile main memory storage, in particular to a persistent memory transaction processing cache management method and device. Background technique [0002] Non-volatile memory (Non-Volatile Memory, NVM) is a new type of byte-addressable memory-level storage device, such as phase change memory (PCM, Phase Change Memory), spin torque memory (STT-RAM, Spin -Torque Transfer RAM), Resistive RAM (RRAM, Resistive RAM), etc. Non-volatile memory has the advantages of low read and write latency, high bandwidth, non-volatility, and low energy consumption. Its read and write performance is close to traditional DRAM memory, and it provides the same persistence as traditional disk external memory. Therefore, memory-level persistent storage (also called "persistent memory") built with non-volatile memory can provide data persistence at the memory level without writing back to disk, greatly improving the performance...
