Technical White Paper System Framework openEuler is used mainly for servers. It consists of the basic acceleration library, virtualization, kernel, driver, compiler, system tool, OpenJDK, and other expansion etMem: unified management of various memory and storage media, and smooth expansion of system capacity • Live kernel upgrade: quick, hitless fixes of kernel vulnerabilities Cloud base: • evaluating the pressure of system resources such as CPU, memory, and I/O. An accurate detection method helps resource users determine a proper workload and enables the system to apply an efficient
