Du Dong, an assistant researcher at Shanghai Jiaotong University, put forward a solution to break through the frontier challenges of heterogeneous distributed operating systems based on the application scenario and ecology of the Internet of everything. Distributed device sharing and collaboration is an important capability in the IoE scenario operating system. Compared with traditional distributed shared memory (DSM) and other classical technologies, distributed devices face challenges such as heterogeneous devices and driver framework coupling of operating systems. In order to meet these challenges, Mr. du put forward some architecture schemes, such as distributed (remote) devices in user-mode framework layer, user-mode hybrid distributed devices in kernel mode, and device pool based on new hardware. these schemes have made some breakthroughs in ease of use, compatibility, performance and other aspects.

As a technical expert on Huawei's OS kernel, Wei Yongjun shared the topic of "extreme performance to build a continuous and smooth foundation kernel base". As a high-performance base, the OpenHarmony kernel elaborated on how to build core features such as Qos IntelliSense scheduling, swap memory management enhancements, F2FS and distributed file systems, while providing priority supply of resources for key businesses. Help OpenHarmony continue to build the competitiveness of fluency, low power consumption and extreme performance.

Wei Yongjun, an expert in Huawei's OS kernel technology, shared the theme.

Mr. Huang ran, a senior technical expert on Huawei terminal graphics and images, believes that game ecology is the most direct way for users to measure the performance of the operating system, and it is very important for the terminal operating system. He introduced the importance of Cocos, Unity and Unreal, the three major engines of mainstream games, and synchronized the ecological construction and some phased achievements of OpenHarmony in cooperation with game engine manufacturers. And call on the community to participate more in the co-construction of the game ecology and jointly build the competitiveness of OpenHarmony's game experience.

Chen Zhonggui, a professor at the School of Information at Xiamen University, believes that in the world of OpenHarmony, window graphics technology can create unlimited possibilities and bring more beautiful changes to the world. In the field of OS window, vector graphics technology is very important, it can use geometric figures based on mathematical equations to describe images. Compared with bitmaps, it has the advantages of independent resolution, small files, easy editing and high print quality, so it is widely used in text, icon and graphic design. However, the drawing of vector graphics is relatively complex, and it needs to go through a rasterization process before display, and the general window system usually contains a large number of vector graphics, so the drawing efficiency of vector graphics has a great impact on the efficiency of windows. High-quality and efficient vector graphics rendering is one of the key technologies of OS windows.

Chen Zhonggui, a professor at the School of Information, Xiamen University, shared the theme.

In addition to the discussion of key window technologies such as vector graphics rendering, Dr. Yang Chengyun, an OS window architect from Huawei, also shared the "development and evolution trend of 2D rendering engine". In this sharing, we see the evolution of 2D rendering engine technology that supports the base of the operating system graphical user interface, and the great impact of its performance and efficiency on the interactive experience of GUI applications. In recent years, with the continuous improvement of display resolution and screen refresh rate of terminal devices and the continuous pursuit of high-definition quality of UI interface by applications, the performance challenges faced by 2D rendering engine have become increasingly prominent. Therefore, it is an urgent task to solve the current challenges by building the next generation 2D rendering engine.
