摘要

持久化内存文件系统通过充分利用持久化内存所具有的非易失性、可字节寻址以及与动态随机存取存储器（DRAM）相媲美的访问延迟等特性，极大提升了文件系统性能。然而，由于持久化内存普遍存在写耐受度低的缺陷，现有持久化内存文件系统空间管理策略导致的不平衡写操作极易将底层持久化内存磨损穿，严重威胁数据可靠性。因此，本文提出一种磨损均衡感知的多粒度分配器（Wear-leveling-aware Multi-grained Allocator，简称WMAlloc），以实现持久化内存的磨损均衡，同时提高文件系统性能。WMAlloc采用不同粒度的最小堆来管理持久化内存的未使用空间。对于每次分配请求，WMAlloc可快速从相应粒度的最小堆中分配磨损较少的块。此外，为避免WMAlloc中空闲块插回多粒度最小堆时触发的节点冗余分割和低效遍历查询可用堆等问题，本文提出一种基于位图的多粒度堆树（BMT）结构来改善WMAlloc，称作WMAlloc-BMT。我们在Linux内核集成的一种典型持久化内存文件系统NOVA中实现了所提WMAlloc和WMAlloc-BMT。实验结果表明，与原始NOVA以及目前持久化内存文件系统最优秀的磨损均衡感知分配器DWARM相比，WMAlloc将持久化内存在4个工作负载下的平均使用寿命分别提高至4.11倍和1.81倍，将平均性能分别提高至1.02倍和1.64倍。此外，与WMAlloc相比，WMAlloc-BMT将文件系统在4个工作负载下的平均性能提高至1.08倍，并将持久化内存平均使用寿命提高至1.17倍。

Abstract

Persistent memory (PM) file systems have been developed to achieve high performance by exploiting the advanced features of PMs

including nonvolatility

byte addressability

and dynamic random access memory (DRAM) like performance. Unfortunately

these PMs suffer from limited write endurance. Existing space management strategies of PM file systems can induce a severely unbalanced wear problem

which can damage the underlying PMs quickly. In this paper

we propose a Wear-leveling-aware Multi-grained Allocator

called WMAlloc

to achieve the wear leveling of PMs while improving the performance of file systems. WMAlloc adopts multiple min-heaps to manage the unused space of PMs. Each heap represents an allocation granularity. Then

WMAlloc allocates less-worn blocks from the corresponding min-heap for allocation requests. Moreover

to avoid recursive split and inefficient heap locations in WMAlloc

we further propose a bitmap-based multi-heap tree (BMT) to enhance WMAlloc

namely

WMAlloc-BMT. We implement WMAlloc and WMAlloc-BMT in the Linux kernel based on NOVA

a typical PM file system. Experimental results show that

compared with the original NOVA and dynamic wear-aware range management (DWARM)

which is the state-of-the-art wear-leveling-aware allocator of PM file systems

WMAlloc can

respectively

achieve 4.11× and 1.81× maximum write number reduction and 1.02× and 1.64× performance with four workloads on average. Furthermore

WMAlloc-BMT outperforms WMAlloc with 1.08× performance and achieves 1.17× maximum write number reduction with four workloads on average.
