interference isolation Anti-hunger and anti-priority-inversion Multi-type resource allocation mechanism RDT MPAM SMT isolation Hard priority Cache/Memory bandwidth interference isolation openEuler inconsistent container OS versions in the cluster. This requires a unified container OS management mechanism. To address these issues, we launched KubeOS, an OS O&M solution that uses Kubernetes to manage a unified manner. Project Introduction KubeOS leverages Kubernetes' CRD+Operator extension mechanism to create custom resources for OSs. This enables the OS to be treated as a Kubernetes resource

terms of metadata management, EXT4 offers insufficient performance in the journal synchronization mechanism, which causes high metadata management overheads and write amplification. These common issues equipped with metadata soft update technology. Its pointer-based directory and dual-view counting mechanism reduces metadata synchronization overheads to effectively improve the call performance of file system implementation and ensures file system consistency. • Pointer-based directory and dual-view counting: This mechanism reduces metadata synchronization overheads and effectively improves the read and write performance

(basic concept) • Section 1.3 (survival method) • Section 1.4 (basic method) • Section 1.5 (shell mechanism) • Section 1.6 (text processing method) 1.2 Unix-like filesystem In GNU/Linux and other Unix-like the modern Linux system, the filesystem under ”/dev/” is automatically populated by the udev(7) mechanism. 1.2.11 Special device files There are some special device files. device file action description shell command Now you have some feel on how to use the Debian system. Let’s look deep into the mechanism of the command execution in the Debian system. Here, I have simplified reality for the newbie. See

optimized fairness of Completely Fair Scheduler (CFS) tasks and the NUMA-aware asynchronous call mechanism combine to bring a significant improvement in NVDIMM initialization. Optimized scheduling reduce interference to other tasks. openEuler 21.03 also has an optimized NUMA balancing mechanism, which brings better affinity, higher utilization, and fewer invalid migrations. 2. Enhanced bandwidth control can be applied on the ARM64 architecture. 17. NMI mechanism based on the SEDI and PMU: This mechanism enables hard lockup detection. Additionally, it enables perf nmi to perform

these events (kernel panic, NMI) the kernel will react automatically and trigger the crash dump mechanism through kexec. In other situations a manual intervention is required in order to capture the memory by inspecting the copied memory contents. Kernel crash dump mechanism When a kernel panic occurs, the kernel relies on the kexec mechanism to quickly reboot a new instance of the kernel in a pre-reserved following command: sudo apt install linux-crashdump Note: Starting with 16.04, the kernel crash dump mechanism is enabled by default. During the installation, you will be prompted with the following dialogs

some of those events (panic, NMI) the kernel will react automatically and trigger the crash dump mechanism through kexec. In other situations a manual intervention is required in order to capture the memory inspecting the copied memory contents. 6.2. Kernel Crash Dump Mechanism When a kernel panic occurs, the kernel relies on the kexec mechanism to quickly reboot a new instance of the kernel in a pre-reserved 04, the kernel crash dump mechanism is enabled by default. During the installation, you will be prompted with the following dialog. Unless chosen otherwise, the kdump mechanism will be enabled. |----
