Frontiers of Information Technology & Electronic Engineering 2023, Volume 24, Issue 5,   Pages 675-687 doi: 10.1631/FITEE.2200469

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.

NEHASH: high-concurrency extendible hashing for non-volatile memory Research Article

Qiankun WANG, Xingchen LI, Bingzhe WU, Ke YANG, Wei HU, Guangyu SUN, Yuchao YANG,gsun@pku.edu.cn

Frontiers of Information Technology & Electronic Engineering 2023, Volume 24, Issue 5,   Pages 731-741 doi: 10.1631/FITEE.2200463

Abstract: The problem (COP), which aims to find the optimal solution in discrete space, is fundamental in various fields. Unfortunately, many COPs are NP-complete, and require much more time to solve as the problem scale increases. Troubled by this, researchers may prefer fast methods even if they are not exact, so approximation algorithms, heuristic algorithms, and machine learning have been proposed. Some works proposed (CSA) based on the Hopfield neural network and did a good job. However, CSA is not something that current general-purpose processors can handle easily, and there is no special hardware for it. To efficiently perform CSA, we propose a software and hardware co-design. In software, we quantize the weight and output using appropriate bit widths, and then modify the calculations that are not suitable for hardware implementation. In hardware, we design a specialized hardware architecture named COPPER based on the memristor. COPPER is capable of efficiently running the modified quantized CSA algorithm and supporting the pipeline further acceleration. The results show that COPPER can perform CSA remarkably well in both speed and energy.
