Shulou(Shulou.com)11/24 Report--

On November 4th, the second OpenHarmony Technical Conference with the theme of "Technology Building Ecology, Zhaopin wins the Future" was held in Beijing. The conference is sponsored by the Technical steering Committee of OpenAtomOpenHarmony (OpenHarmony) Project Group (TSC) and supported by Huawei Technology Co., Ltd., Jiangsu run Kaihong Digital Technology Co., Ltd., Guangdong Jiulian Kaihong Technology Development Co., Ltd., Softong Power Information Technology (Group) Co., Ltd., Shenzhen Kaihong Digital Industry Development Co., Ltd. Technical experts from industry and academia gathered together to share progress and look forward to the future around the technological innovation of OpenHarmony and the co-construction and sharing of industry-university-research.

At the opening ceremony, Chen Haibo, chairman of the Technical steering Committee of the OpenHarmony project group and chief scientist of Huawei basic software, gave a keynote speech entitled "OpenHarmony Technology takes the lead in Building Ecology and the Alliance of everything wins the Future". Centering on the trend of the Alliance of everything, he shared the key technological achievements and future evolution directions of the four major technical architecture features of OpenHarmony, and released a number of recent technical projects incubated by the Technical steering Committee. " OpenHarmony has established the "OpenHarmony Technology Club" with 17 universities. In the future, it will further move towards the industry-university-research community and jointly build a shared operating system technology and talent ecology through industrial and academic two-wheel drive.

With deep roots and luxuriant leaves, the four major technological architectures of OpenHarmony are ahead of the competition, and the ecology is booming.

OpenHarmony takes "facing the Wisdom world, building an open source operating system base and ecosystem with distributed panoramic collaboration" as its technology vision, adhering to the ecological concept of "ecological unity, openness and win-win", and facing the trend of the Wisdom era, and constructs four technical architecture features: "architecture decoupling, elastic expansion", "heterogeneous parallelism, full-stack collaboration", "native intelligence, scene experience" and "minimalist development, multi-terminal deployment". The current technical conference also released open source projects such as "provable High performance and High Reliability concurrent VSync", "trusted execution Environment solution OpenTrustee" and "Cross-platform Application Development Framework ArkUI-X" recently incubated by the Technical steering Committee of the OpenHarmony project cluster.

1) "Architecture decoupling and elastic expansion"

In the era of the Alliance of everything, the operating system first needs to overcome the challenge of "insect paradox". The shape of terminal devices is explosively growing, and only a unified architecture and intelligent interconnection can gather strength. Based on the concept and technology of "meta-OS architecture", OpenHarmony supports various distributions to flexibly combine operating systems on demand, so as to meet the needs of thousands of industries and industries, and facilitate the provision of open and unified ecological capabilities.

2) "heterogeneous parallelism and full stack collaboration"

Facing the evolution of hardware architecture in the post-Moore era, OpenHarmony innovates from the whole stack of technologies that are critical to performance, such as concurrency, scheduling, memory and storage.

"heterogeneous native concurrency" greatly reduces the system load and scheduling overhead through an innovative concurrency model, and verifies that the access to shared resources does not exceed the bounds through formal proof.

"IntelliSense scheduling" perceives the CPU micro-architecture in real time, links the hardware resources of the whole system, takes the user experience as the center, perceives the application scene, and realizes the accurate and overall supply of system resources, so as to achieve the double benefits of high fluency and long-term flight of the terminal system.

The innovation of "Super memory Management" realizes the deep integration of memory and storage, greatly increases the available memory, and then improves the fluency of user experience in heavy-load scenarios.

"High-performance read-only compressed file system EROFS" saves user space, improves performance, not only through OpenHarmony open source, but also as the first domestic standard file system open source to the Linux community and Android open source community, benefiting billions of terminals around the world.

At the same time, the "provable high performance and high reliability concurrent VSync" with deep academic research is being incubated by the Technical steering Committee for open source recently.

3) "native intelligence, scene experience"

At the beginning of OpenHarmony design, the distributed panoramic view capability is regarded as the most key technical architecture feature, and it is convenient to achieve industry leadership in distributed soft bus, distributed data management, distributed device management and so on. Embracing the era of Wisdom of everything, OpenHarmony will further enhance the competitiveness of intelligent experience, evolve to immersive interaction and embodied intelligence, build a native intelligent architecture, and enhance security and privacy protection. OpenTrustee, an open source trusted execution environment solution recently incubated by the Technical steering Committee, provides a robust TEE security base and system protection capabilities to support a wide range of security application scenarios.

4) "minimalist development, multi-terminal deployment"

For developers, OpenHarmony has created key technologies such as low code development, full-stack collaborative in-depth optimization, and cross-platform framework. The cross-platform application development framework open source project ArkUI-X, which is incubated by the Technical steering Committee and jointly built by Huawei, Ali, Midea, Shenkaihong and other units, has been launched recently.

Zhong Xing Zhiyuan, OpenHarmony industry-university-research deep integration, co-building shared technology and talent ecology

OpenHarmony has established the "OpenHarmony Technology Club" with 17 universities, and will further move towards the industry-university-research community in the future. Through industrial technical problems, cutting-edge academic research, lectures, forums, competitions, technology and industrial standards incubation to form industrial and academic two-wheel drive closed loop, and jointly build a shared operating system technology and talent ecology.

With deep roots and luxuriant leaves, everyone goes far away. OpenHarmony embraces the era of the Alliance of everything, led by the four major technological architecture features, and promotes the vigorous development of ecology through the deep coordination of industry, university and research. OpenHarmony has become one of the fastest growing intelligent terminal operating system open source communities, with more than 6200 developers from 51 co-building units participating in the community contribution, with a total of more than 100 million lines of code, and more than 425 software and hardware products have passed the compatibility test, covering key industries such as energy, industry, aerospace, transportation, education, government and so on.
