Abstract

In this paper, we introduce memos, which integrates suitable memory management policies and schedules resources over the entire memory hierarchy in hybrid memory system. Powered by an OS kernel level monitoring tool, memos captures memory patterns online, and then leverages them to guide the memory page placement and data mapping. Experimental results show, on average, memos can benefit memory utilization, contributing to system throughput and QoS by 19.1% and 23.6%. Moreover, memos can reduce the NVM side memory latency by 3~83.3%, energy consumption by 25.1~99%, and benefit the NVM lifetime significantly (40× improvement on average).

备忘录:一个完整的层次混合内存管理框架

在本文中，我们介绍了备忘录，它集成了合适的内存管理策略，并在混合内存系统的整个内存层次上调度资源。在操作系统内核级监视工具的支持下，备忘录在线捕获内存模式，然后利用它们指导内存页的放置和数据映射。实验结果表明，备忘录可以提高内存利用率，使系统吞吐量和QoS分别提高19.1%和23.6%。此外，备忘录可使NVM侧内存延迟降低3~83.3%，能耗降低25.1~99%，显著提高NVM寿命(平均提高40倍)。
