NICFS: a file system based on persistent memory and SmartNIC Research Article

Frontiers of Information Technology & Electronic Engineering 2023, Volume 24, Issue 5,   Pages 688-702 doi: 10.1631/FITEE.2200468

Abstract: (PM) s 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 s can induce a severely unbalanced wear problem, which can damage the underlying PMs quickly. In this paper, we propose a -aware , called WMAlloc, to achieve the wear leveling of PMs while improving the performance of s. 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 . Experimental results show that, compared with the original NOVA and dynamic wear-aware range management (DWARM), which is the state-of-the-art -aware allocator of PM s, 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.

Abstract: Emergence of new hardware, including and , has brought new opportunities to design. In this paper, we design and implement a new named NICFS based on and SmartNIC. We divide the into two parts: the front end and the back end. In the front end, data writes are appended to the in a log-structured way, leveraging the fast persistence advantage of . In the back end, the data in logs are fetched, processed, and patched to files in the background, leveraging the processing capacity of SmartNIC. Evaluation results show that NICFS outperforms Ext4 by about 21%/10% and about 19%/50% on large and small reads/writes, respectively.

Theory and method of mechanism system design

Frontiers of Mechanical Engineering 2010, Volume 5, Issue 4,   Pages 399-411 doi: 10.1007/s11465-010-0116-8

Abstract: Conceptual design is the most critical and creative phase of design. Recently, increasing attention has been directed to supporting conceptual-level computer aided creative design and its theories and methodologies. Specifically, for conceptual design of mechanical products, this paper presents a novel function solving model for mechanical product design and highlights the importance of systematic synthesis to achieve creative design. Then it builds a framework as a function-effect-process-action- mechanisms (FEPAM) mapping process, which enables creative design on the basis of conceiving different action schemes. After that, several key points are elaborated including 1) representing and decomposition methods of functions and motion behaviors; 2) action scheme representing method based on network plan techniques; and 3) variation and creation methods based on action scheme transformations.
