厦门领航立华科技有限公司

openEuler is an efficient, stable, and secure open-source Linux OS , applies to database, big data, cloud computing, and artificial intelligence (AI).

openEuler is an open-source operating system. The current openEuler kernel is based on Linux and supports multiple processors. It fully unleashes the potential of computing chips. As an efficient, stable, and secure open-source OS built by global open-source contributors, openEuler applies to database, big data, cloud computing, and artificial intelligence (AI) scenarios. # Key Features: openEuler 22.03 LTS is built based on Linux Kernel 5.10 and absorbs beneficial features and innovative features of later versions from the community. -Memory RAS – reliable memory: More extensive support for reliable memory, which is used by the kernel, key processes, memory file system, and file cache to prevent kernel resets caused by multi-bit errors (MBEs). -Memory RAS – enhanced UCE tolerance: In the event the copy_from_user experiences an MBE, the affected processes can be killed to avoid a kernel reset. -Programmable kernel: The kernel scheduler can dynamically extend scheduling policies to diverse requirements. -Resource isolation: cgroup v1 supports iocost. Users can configure weights to allocate I/O resources. -CXL support: Addition of the Root Complex Event Collectors (RCEC), which is part of the Advanced Error Reporting (AER) PCI Express feature. -Commissioning: The perf c2c tool now runs on AArch64 Statistical Profiling Extension (SPE) to detect cache pseudo-sharing and locate bottlenecks. -AF_UNIX socket optimization: The connection delay and CPU usage are greatly reduced in concurrent tasks.
