The June Shanghai offline gathering was successfully held yesterday. This event was organized and hosted by Kubuds Technology, with over 30 participants traveling from multiple cities to share and exchange insights on various hot topics including compilers, robotics, the RISC-V Championship, and the RISC-V Prosperity 2036 documentation project.

openEuler ROS SIG Maintainer, Engineer Wang Xiaoyun from the Institute of Software, Chinese Academy of Sciences, delivered a speech titled ‘openEuler ROS Development, Applications, and Outlook’

Engineer Wang Xiaoyun first provided an overview of the current state of the open-source Robot Operating System (ROS), noting its daily active developer count reaching hundreds of thousands and its creation of billions of dollars in industry value. She then reviewed the origins of the ROS SIG and the development journey of openEuler ROS, highlighting the latest progress: the openEuler 24.03 LTS version has released over 1000 ROS software packages, achieving support for both ROS1/ROS2 versions and X86/ARM/RISC-V multiple architectures.

Through videos, Engineer Wang Xiaoyun demonstrated the significant achievements of openEuler ROS to the attendees, including application cases like unmanned vehicles and other robots, such as the RISC-V MicroROS car and zodiac robots. She expressed great anticipation for the future development of openEuler ROS, hoping for its continuous maintenance and feature expansion, adaptation to more development boards, active promotion by the community, and realization of more practical applications. As the chief mentor of the openEuler ROS SIG, Wang Xiaoyun also shared the ROS robotics development intern program and encouraged interested students to actively participate.

openEuler RISC-V SIG Maintainer, CTO Wang Junqiang of Kubuds Tech, shared a speech titled ‘LLVM Parallel Universe: Towards a Multi-Star Civilization, Announcing the Quantum Leap Path’

Mr. Wang Junqiang first introduced the development history of the LLVM Parallel Universe Project and briefly shared its progress over the past year, supported by the openEuler RISC-V SIG and openEuler Compiler SIG.

Immediately after, he presented the newly launched openKylin LLVM Parallel Universe Project (launched this month) and elaborated on the content of the J126 internship position—established under the “RISC-V Prosperity 2036 Open-Source Intern Joint Recruitment and Training Program”. He called on more college students to join the LLVM Parallel Universe, describing it as a highly engaging project.

Wang Junqiang also introduced KarsierOS to the audience. KarsierOS is a downstream commercial distribution derived from the achievements of the openEuler LLVM Parallel Universe by Kubuds Tech, scheduled for official release at the RISC-V China Summit on August 21. This might be the first commercial distribution based on the Parallel Universe outcomes.

The most compelling part of his sharing came at the end: Mr. Wang Junqiang officially unveiled the “Quantum Leap Path” Project . The plan aims to achieve the freedom to switch compilers, linkers, and basic libraries of the “full-system software supply chain” on demand within approximately five years.

Engineer Zhou Jiacheng from the OERV team of the Institute of Software, Chinese Academy of Sciences, shared a speech titled ‘Introduction and Progress of the openEuler LLVM Parallel Universe Plan’.

Zhou Jiacheng first reviewed the background of the LLVM Parallel Universe Project—namely, the open-source community’s journey of building Linux distributions with LLVM Clang. He then gave a basic introduction to the project: it aims to replace the GCC suite with the LLVM compiler suite to build Linux distributions and packages, developing in parallel with community versions independently. This is why the openEuler Community named the project “Parallel Universe”.

Then, he shared several major advantages of LLVM and the reasons for choosing it, including its excellent architecture design, friendly licensing, and vibrant ecosystem. Furthermore, he mentioned that LLVM is also competitive in areas like code quality detection, native support for Rust kernel driver development, and its widespread recognition in both industry and academia.

Subsequently, Zhou Jiacheng detailed the current status and operation mode of the openEuler Parallel Universe Project, including how to switch to the LLVM/Clang compiler during the build process, the scope of packages involved in the compiler switch, and the status of supporting infrastructure.

Finally, he shared information about the recent new version release of the openEuler Parallel Universe Project, download links, and the general plan for future development.

Ms. Wang Wenjun, Chair of the Organizing Committee for the Second RISC-V Software Porting and Optimization Championship (RVSPOC), announced the opening of registrations and the start of the competition at this event.

Ms. Wang Wenjun first acknowledged the achievements of the First RISC-V Software Porting and Optimization Championship, which ultimately yielded over 20 high-quality PRs and recognized 10 champion teams.

Then, she announced the opening of registrations and the start of the Second RISC-V Software Porting and Optimization Championship. Subsequently, Mr. Li Cheng, Team Lead of Kubuds Tech’s Cyber Lemon team and also Chair of the first championship, provided a preview release of the competition tasks.

Mr. Li Cheng, Team Lead of Kubuds Tech’s Cyber Lemon team and Chair of the First Championship, delivered ‘A Preview Release of the Tasks for the Second RISC-V Software Porting and Optimization Championship’

Mr. Li Cheng released the tasks for the Second RISC-V Software Porting and Optimization Championship, which included “New 32-bit Type-1 Hypervisor Porting”, “Optimized Implementation of Llama 3 on TH1520”, “OceanBase Porting and Optimization”, “TDengine Porting and Optimization”, and “RetroArch Porting and Optimization”. Mr. Li Cheng gave a brief introduction to each task, outlined the corresponding requirements and scoring criteria, and emphasized that the tasks are currently in the preview release stage and might be adjusted dynamically later.

Additionally, during the meeting break, Mr. Li Cheng announced the news about the “RISC-V Prosperity 2036 opens J128 Deepin Operating System Development Intern (RISC-V Architecture) - Open Source Intern Joint Recruitment and Training” and, as the chief mentor for this intern position, called for interested students to join the internship.

Zhang Xiang, Community Operations Advisor at Kubuds Tech, shared a speech titled ‘From Internship to Innovation: My Path in Technical Construction and Community’

Zhang Xiang first briefly introduced his own background with ROS and RISC-V, starting from his internship during postgraduate studies in 2018 where he encountered ROS, joining the PLCT lab in 2021 and getting involved with RISC-V, until this year choosing to join Kubuds Tech to explore a new career direction in community operations.

He further shared some perspectives on community building, stating his intention to do meaningful work in the community operations role, dedicated to promoting the construction of the RISC-V ROS community, fostering a good environment for community exchange, and striving to create fertile ground for cultivating technical talent.

Zhang Xiang focused on introducing the relevant situation of riscvpedia, which is positioned as an encyclopedia for RISC-V users, an open-source git repository collecting all RISC-V products and related software information on the market, planned to be updated every three months. He briefly introduced the framework and organizational structure of riscvpedia, noting that everything is currently in the initial planning stage. Finally, Zhang Xiang presented the goal of riscvpedia: by the time 2036 arrives, he hopes that among over 50 million RISC-V users, there will be more than 1 million registered members of riscvpedia, and he called for more people to participate.

Lastly, on behalf of Kubuds Tech, Zhang Xiang announced joining the ROS SIG and, under the framework of the RISC-V Prosperity 2036 ‘Joint Intern Recruitment and Training Project’, will specifically open 50 open-source intern positions to participate in the construction of the openEuler community’s ROS SIG, striving to make more contributions to the development of the ROS ecosystem.
