General Community Questions ​

What is openEuler ​

The OpenAtom openEuler project, short for openEuler, is an open-source OS project incubated and operated by the OpenAtom Foundation. It started as a simple server OS but has now blossomed into a full-blown digital infrastructure OS, supporting server, cloud, edge, and embedded deployments. This Linux distribution is compatible with multiple instruction set architectures and ideal for a wide range of operational technology applications, enabling OT-ICT convergence.

What is the openEuler community like ​

Established officially on December 31, 2019, the openEuler community operates as a global hub for developers worldwide, aiming to foster an open, diverse, and architecture-inclusive software ecosystem tailored for wide-ranging digital infrastructure needs. openEuler collaborates closely with both upstream and downstream communities to ensure continuous tech improvement and timely release of new versions.

What instruction set architectures does openEuler support ​

With active collaboration from leading chip vendors like Intel and AMD, openEuler supports multiple processor architectures, including x86, Arm, SW64, RISC-V, and LoongArch, with plans to expand to PowerPC.

openEuler is optimized for a wide range of CPU chips, such as Loongson 3 series, Zhaoxin KaiXian and KaiSheng, Intel Sierra Forest and Granite Rapids, and AMD EPYC Milan and Genoa. openEuler's compatibility extends beyond the CPU, encompassing NIC, RAID, Fibre Channel, GPU & AI, DPU, SSD, and security cards.

By offering a unified OS that can run on various devices, openEuler facilitates streamlined application development, allowing developers to target a wide range of hardware without significant code modification.

How often does openEuler release a new version ​

openEuler releases two types of community versions: long-term support (LTS) and innovation versions.

LTS versions, like openEuler 20.03 LTS and openEuler 22.03 LTS, are released every two years and provide community support for four years. This includes two years of maintenance support and two years of extended support.

Innovation versions are released every six months, with each receiving community support for six months.

Prior to the end of any version's lifecycle, users will receive notifications from our mailing lists three months in advance.

What are openEuler's special interest groups all about and How can I join one ​

The openEuler community is home to 100+ SIGs, each dedicated to a specific project or topic. These groups drive innovation in areas like toolchains, architectures, desktop environments, universal middleware, cloud-native infrastructure, and more! Our SIGs are hot on the heels of trends like AI, embedded systems, RISC-V, security, and compliance. They manage repositories, contribute to code, and even help shape community governance & operations.

You can find the full list of openEuler SIGs and their descriptions here.

• Interested in joining an existing SIG? Send an email to the group's email address or contact the maintainers directly.

• Can I start my own SIG? Absolutely! We have a simple and easy process for setting up a new SIG.

Hmm, openEuler... Who's using it ​

openEuler isn't just open-source — it's powering real innovation from semiconductors to a wide range of industries like operating systems, Internet, finance, carrier, electric power, manufacturing, energy, education, transportation, healthcare, and other fields. Companies tailor openEuler to their needs, creating commercial and enterprise distributions for both internal and external usage, and some of these companies have implemented large-scale deployments of these distributions.

We're all about making the future brighter and more open-source! Check out our success stories.

What does "noise" in the openEuler refer to ​

OS noise includes non-application computing tasks executed during service running, such as:

• System/User-mode daemon processes
• Interrupt processing
• Processes in user mode or kernel
• Memory management and scheduling overhead
• Non-computing tasks in service applications (e.g., monitoring logs and thread communication)
• Resource competition (e.g., cache misses and page faults)

Where can I find common repositories for openEuler ​

You can find sorted and classified repositories for various openEuler versions on the openEuler Forum.
