In recent years, with the rapid development of the Internet of Things, the Internet, and social networks, the storage of data in the network is growing at an explosive rate and is becoming more and more closely related to the real natural world. Driven by large-scale data mining and machine learning applications, distributed graph computing models that use graph data structures to describe data and relationships between data have been increasingly widely used. Therefore, this paper studies the optimization of communication mechanisms based on a distributed graph computing environment. Firstly, a BSP model based on a pure message-passing communication mechanism of a distributed graph computing system is established. Secondly, the optimization model is evaluated from two aspects: data communication and convergence condition judgment. Finally, large-scale data sets are used to test and evaluate performance optimization. The results show that this method can greatly improve the efficiency of graph parallel computing.

High Performance computing (HPC) has become an indispensable tool in various scientific and engineering domains, demanding efficient infrastructure to support computationally intensive tasks. Cloud computing platforms, such as Amazon Web Services (AWS), have emerged as a viable solution for provisioning HPC resources. In this work, we explore the performance of HPC workloads running on AWS, utilizing Elastic Fabric Adapter (EFA) interconnect technology and Intel Xeon Scalable Processors. The investigation focuses on Message Passing Interface (MPI) applications, evaluating the system's efficiency, scalability, and the benefits of EFA integration. We present experimental results and insights into optimizing HPC workloads in the AWS environment, contributing to the ongoing discussion on achieving high-performance computational capabilities in the cloud.

State estimation is the foundation for a variety of online power system applications in energy management systems, and the stability of power systems is directly impacted by the speed with which current system states can be obtained through state estimation. This paper proposed a fast Gaussian-Newton state estimation method for power systems based on parallel belief propagation, which implements the Gaussian belief process via multi-core and multi-thread parallel computation to achieve efficient state estimation. Simulation findings on numerous IEEE-standard power systems show that the suggested technique outperforms the traditional algorithm.

IoT-based smart grids, as a cutting-edge research direction in the energy field, have sparked extensive interest and research. In this context, As an emerging computing paradigm, edge computing presents new opportunities for smart grid implementation and optimisation. The purpose of this research is to investigate the implementation of peripheral computation in IoT-based smart infrastructure and its potential value and impact on power systems. In this study, we begin by introducing the fundamental concepts of IoT-based smart grid and edge computing, before describing their relationship and the function of edge computing in smart grid. Subsequently, we concentrate on specific smart grid application areas for peripheral computation. Including energy management, load balancing, fault monitoring, and real-time data analysis. By applying in these areas, edge computing can provide real-time data processing and decision support to achieve efficient operation and optimized management of power systems. Further, this study explores the challenges and opportunities presented by edge computingapplications. We analyze the problems that edge computing may face in terms of data security, communication delay, and resource allocation, and propose corresponding solution strategies. At the same time, we emphasize the innovation and sustainability of edge computingapplications in smart grids, providing new ideas and methods for the future development of power systems. Finally, this study summarizes the advantages and prospects of edge computingapplications in smart grids based on IoT, and proposes directions for future research.
