一种高效的持久性内存管理系统设计

Design on an efficient persistent memory management system

近年来,研究者针对持久性内存的管理做了许多工作,但仍存在一些问题,比如未考虑数据一致性、读写不对称和非均匀存储器存取特性。文章提出了一种高效的持久性内存管理系统,设计了基于内存缓存的一致性策略,和基于非均匀存储器存取特性的多粒度内存管理策略。测试结果表明,在多线程下,分配内存大小为64字节时,相比于Makalu,持久性内存管理系统的平均性能提高了38.6%。

In recent years, researchers have done a lot of work on persistent memory management, but there are still some problems, such as not considering data consistency, asymmetric reading and writing memory access characteristics. In this paper, an efficient persistent memory management system is proposed, and a consistency strategy based on memory cache and a multi-granularity memory management strategy based on non-uniform memory access characteristics are designed. The test results show that compared to the Makalu, persistent memory management system is improved by 38.6% when the memory allocation size is 64 bytes under multithreading.
