Allreduce algorithm optimization of OpenMPI communication library 优化 OpenMPI 通信库的 Allreduce 算法
Guangyao Zhang, Wei Wan, Junhong Li
MPI (Message Passing Interface) plays a crucial role in the field of parallel computing. In the Allreduce algorithm of the OpenMPI communication library, there are some issues in handling communication scenarios with a number of processes that is non-power-of-two. The two existing algorithms address this by excluding some processes to achieve a power-of-two process count. However, the consideration factors are too simplistic, resulting in an imbalanced distribution of participating processes on nodes, greatly impacting communication efficiency. To address this problem, the layout of processes on nodes is taken into consideration, and the range of excluded processes is redefined. Both algorithms are subjected to generic load balancing optimizations and adaptations for domestic architectures, resulting in improved load balancing. Experimental results show that, under a communication scale of 16 nodes, the recursive_doubling algorithm achieves performance improvements of up to 30%, while the reduce_scatter_allgather algorithm achieves performance improvements of up to 21%.
MPI(消息传递接口)在并行计算领域发挥着至关重要的作用。在 OpenMPI 通信库的 Allreduce 算法中,在处理进程数为非两倍幂的通信场景时存在一些问题。现有的两种算法通过排除一些进程来解决这个问题,以实现进程数为 2 的幂次方。但是,考虑的因素过于简单,导致节点上参与进程的分布不平衡,极大地影响了通信效率。为了解决这个问题,我们考虑了节点上的进程布局,并重新定义了排除进程的范围。这两种算法都针对国内架构进行了通用负载平衡优化和调整,从而改善了负载平衡。实验结果表明,在 16 个节点的通信规模下,递归加倍算法的性能最多可提高 30%,而减少分散聚集算法的性能最多可提高 21%。

DRLMS: a multipath scheduler based on deep reinforcement learning DRLMS:基于深度强化学习的多路径调度程序
Mengyang Zhang, Kaiguo Yuan, Xiaoyong Li
Most current network devices have multiple network interfaces, and multipath transport protocols can utilize multiple network paths (e.g., WiFi and cellular) to improve the performance and reliability of network transmission. The scheduler of the multipath transmission protocol determines the path to which each data packet should be transmitted, and is a key module that affects multipath transmission. However, current multipath schedulers cannot adapt well to various user usage scenarios. In this paper, we propose DRLMS, a deep reinforcement learning based multipath scheduler. DRLMS uses deep reinforcement learning to train neural networks to generate packet scheduling policies. It optimizes the scheduling strategy through feedback to the neural network through the reward function based on the current user usage scenario and QoS. We implement DRLMS in the MPQUIC protocol and compared it with current multipath schedulers. The results show that DRLMS's adaptability to user usage scenarios is significantly outperforms other schedulers.
目前大多数网络设备都有多个网络接口,多路径传输协议可以利用多条网络路径(如 WiFi 和蜂窝网络)来提高网络传输的性能和可靠性。多路径传输协议的调度器决定每个数据包应传输到哪条路径,是影响多路径传输的关键模块。然而,目前的多路径调度器不能很好地适应各种用户使用场景。本文提出了基于深度强化学习的多路径调度器 DRLMS。DRLMS 利用深度强化学习训练神经网络来生成数据包调度策略。它根据当前的用户使用场景和服务质量,通过奖励函数向神经网络提供反馈,从而优化调度策略。我们在 MPQUIC 协议中实施了 DRLMS,并将其与当前的多路径调度器进行了比较。结果表明,DRLMS 对用户使用场景的适应性明显优于其他调度器。

Cost-aware service function chain migration in satellite-ground integrated networks 卫星-地面集成网络中成本感知服务功能链迁移
Zhiyu Fu, Jing Ran, Hefei Hu
The integration of satellite and ground networks (SGIN) represents a significant advancement in the evolution of 6G mobile technologies. The rapid movement of satellites leads to swift changes in network topology. By adjusting the Service Function Chain (SFC) to these frequent changes, it's possible to diminish SFC delay and enhance the user experience. This study addresses the challenge of SFC migration within the dynamic SGIN framework. We initially developed a mathematical formulation for the VNF migration and SFC reconfiguration task, with the objective of optimizing the total system benefits. An enhanced genetic algorithm was introduced as a solution, striking an optimal compromise between SFC delay and the expenses associated with migration. When we compare our findings to previous algorithms, it's clear that our method substantially reduces the costs linked to network migration, enhances the overall profitability of services, and achieves a more favorable balance between SFC latency and migration costs.

Research on netizen sentiment recognition based on multimodal deep learning 基于多模态深度学习的网民情感识别研究
Nan Jia, Tianhao Yao
With the rapid popularity of social media and the Internet, network security issues are becoming increasingly prominent. More and more people are accustomed to expressing their emotions and opinions online, and the expression of netizens’ emotions is becoming more and more diversified. Accurate analysis of netizens’ emotions is particularly important. Traditional emotion recognition methods are mainly based on text analysis, but with the diversification of network media, single text analysis has been unable to meet the actual needs. Therefore, continuously exploring the application of multimodal deep learning in netizen emotion recognition has become an inevitable choice for public security organs. This paper aims to explore the application of multimodal deep learning in netizen emotion recognition research. Therefore, this study uses multimodal datasets of text and images, and constructs BERT and VGG-16(fine-tuning) models to extract emotional features from text mode and image mode respectively. By introducing the multi-head attention mechanism, the two modes are combined to establish a fusion model, and explores how to combine them to improve classification performance. The final accuracy of text modality is 0.70, the accuracy of image modality is 0.58, and the accuracy of multimodal fusion model is 0.73, which is 0.03 and 0.15 higher than that of text modality and image modality, respectively, proving the scientific nature of multimodal fusion model. It can provide new ideas and methods for the analysis and early warning of public security organs, and also provide reference and inspiration for the research in other fields.
随着社交媒体和互联网的迅速普及,网络安全问题日益突出。越来越多的人习惯在网上表达自己的情绪和观点,网民情绪的表达方式也越来越多样化。对网民情绪的准确分析显得尤为重要。传统的情感识别方法主要基于文本分析,但随着网络媒体的多样化,单一的文本分析已经不能满足实际需要。因此,不断探索多模态深度学习在网民情绪识别中的应用已成为公安机关的必然选择。本文旨在探索多模态深度学习在网民情感识别研究中的应用。因此,本研究使用文本和图像的多模态数据集,构建了BERT和VGG-16(微调)模型,分别从文本模式和图像模式中提取情感特征。通过引入多头关注机制,将两种模式结合起来建立融合模型,并探索如何将它们结合起来以提高分类性能。最终文本模式的准确率为 0.70,图像模式的准确率为 0.58,多模态融合模型的准确率为 0.73,分别比文本模式和图像模式的准确率高出 0.03 和 0.15,证明了多模态融合模型的科学性。它可以为公安机关的分析预警提供新的思路和方法,也可以为其他领域的研究提供借鉴和启发。

Tabu-based adaptive large neighborhood search aids irregular reconfigurable intelligent surface capacity enhancement 基于 Tabu 的自适应大邻域搜索辅助不规则可重构智能表面能力提升
Songyue Yang, Zhiguo Sun, Rongchen Sun
The development of 6G has led to the need for communication systems to realize low latency, high throughput and stable connectivity. To achieve these goals, Reconfigurable Intelligent Surface has emerged. However, for RIS with massive elements, the overhead caused by channel estimation and feedback is not negligible. In this article, we address this problem using irregular RIS, which essentially involves irregularly rationing a specified number of reflective elements on an RIS surface, by providing additional spatial degrees of freedom to achieve performance gains. To this end, we formulate the problem of joint topology and precoding matrix joint optimization with tabu-based adaptive large neighborhood search for channel capacity maximization.
6G 的发展促使通信系统需要实现低延迟、高吞吐量和稳定的连接。为了实现这些目标,可重构智能表面应运而生。然而,对于具有大量元素的可重构智能表面(RIS)来说,信道估计和反馈造成的开销不容忽视。在本文中,我们利用不规则 RIS 解决了这一问题。不规则 RIS 本质上是在 RIS 表面上不规则地分配指定数量的反射元件,通过提供额外的空间自由度来实现性能提升。为此,我们利用基于 tabu 的自适应大邻域搜索,提出了联合拓扑和预编码矩阵联合优化问题,以实现信道容量最大化。

Wavelength design and optical axis correction for bidirectional underwater laser communication with ATP 利用 ATP 进行双向水下激光通信的波长设计和光轴校正
Juan Wang, Zhe Li
This paper addresses the issues of wavelength selection and isolation for underwater full-duplex laser communication automatic tracking of beacon light signals. A method for four-wavelength reception and transmission isolation in the blue-green light band is proposed, which utilizes watt-level semiconductor lasers to achieve beacon light signals with orders of magnitude divergence angles, aiding in rapid acquisition and alignment. The underwater transmission distance of beacon light is close to that of signal light with small divergence angles. Additionally, the hemispherical dome used for waterproof sealing in the underwater laser communication ATP device has a significant impact on the alignment consistency of beacon light and signal light axes. This paper simulates the non-parallelism of underwater optical axes using ray tracing and corrects the non-parallelism of underwater optical axes by presetting a reverse bias angle, addressing the feasibility issue of independent beacon light application in underwater ATP devices and improving the performance of underwater laser communication.

A privacy preserving carbon quota trading and auditing method 一种保护隐私的碳配额交易和审计方法
Hao Huo, Cunpei Li, Boyi Wang, Yipeng Yang, Yuhan Chen, Peng Liu
Carbon dioxide emissions are an important cause of dramatic changes in climate. Therefore, the control of carbon emission rights of relevant subjects is a necessary prerequisite for mitigating climate change. However, the existing carbon trading and auditing framework has not yet completed the control of relevant entities under the premise of considering privacy, and adversaries may infer the privacy information of emission entities based on carbon emission data. In response to this challenge, this paper proposes a novel carbon data collection, carbon trading and auditing method based on block chain and the Internet of Things. This method realizes the trusted storage of carbon data through block chain technology. At the same time, in order to protect user privacy, the interaction of carbon data is carried out through HE. Security analysis shows that our method can prevent user privacy leakage. Experimental analysis shows that the method still maintains good availability while having high security.

A local flooding-based survivable routing algorithm for mega-constellations networks with inclined orbits 基于局部泛洪的倾斜轨道巨型星座网络可生存路由算法
Jun He, Hefei Hu, Simin Feng
Low-orbit satellite communication has the advantages of global coverage and low latency, and the satellite network is developing in the direction of gigantism, low orbital altitude, tilted orbit, and inter-satellite link networking, which brings more challenges to the design of routing algorithms. Aiming at the characteristics of mega-constellation networks (MCNs), this paper proposes a local flooding-based survivable routing algorithm (LFSA) that obtains the local link-state information by limiting the flooding range, to reduce the flooding and computation overheads of the network. Based on the topological characteristics of MCNs, a next-hop selection mechanism based on minimum Manhattan distance is proposed. Simulation results show that the LFSA algorithm improves the pathfinding capability and reduces end-to-end delay in the face of random link failure and regional satellite failure.
低轨卫星通信具有全球覆盖、低时延等优点,卫星网络正朝着巨型化、低轨道高度、倾斜轨道、星间链路组网等方向发展,这给路由算法的设计带来了更多挑战。针对超大型星座网络(MCN)的特点,本文提出了一种基于本地泛洪的可生存路由算法(LFSA),通过限制泛洪范围获取本地链路状态信息,减少网络的泛洪和计算开销。根据 MCN 的拓扑特性,提出了基于最小曼哈顿距离的下一跳选择机制。仿真结果表明,面对随机链路故障和区域卫星故障,LFSA 算法提高了寻路能力,减少了端到端延迟。

Aiming at the characteristics of mega-constellation networks (MCNs), this paper proposes a local flooding-based survivable routing algorithm (LFSA) that obtains the local link-state information by limiting the flooding range, to reduce the flooding and computation overheads of the network. Based on the topological characteristics of MCNs, a next-hop selection mechanism based on minimum Manhattan distance is proposed.
