The content of this article is about creating a supercomputing cluster instance by referring to the description of creating an ECS instance. It has certain reference value. Friends in need can refer to it. I hope it will be helpful to you.
Super Computing Cluster Details
Super Computing Cluster (Super Computing Cluster, referred to as SCC) is an elastic bare metal On the basis of the server, high-speed RDMA interconnection support is added to greatly improve network performance and increase the acceleration ratio of large-scale clusters. Therefore, while supercomputing clusters provide high-bandwidth, low-latency high-quality networks, they also have all the advantages of elastic bare metal servers. For details, please refer to Elastic Bare Metal Servers (Dragon) and Super Computing Clusters (SCC).
Please refer to Supercomputing Cluster Instance Specification Family for detailed instance specification information.
Create an instance
You can refer to the description of Creating an ECS instance to create a supercomputing cluster instance. However, when creating an instance, you need to pay attention to the following settings:
Region: Currently, only Availability Zone D and Availability Zone B of East China 2 can be selected.
Network: Only supports private networks (VPC networks).
Instance: Supports scch5 (high-frequency supercomputing cluster instance specification family) and sccg5 (general-purpose supercomputing cluster instance specification family).
Image: Select System Image. Currently supports customized version of Linux CentOS 7.5.
Storage: The supercomputing cluster supports mounting up to 16 data disks. You can add a data disk here, or you can create and mount the data disk separately after the instance is successfully created.
The above is the detailed content of Refer to the description of creating an ECS instance to create a supercomputing cluster instance.. For more information, please follow other related articles on the PHP Chinese website!
The 5 Core Components of the Linux Operating SystemMay 08, 2025 am 12:08 AMThe five core components of the Linux operating system are: 1. Kernel, 2. System libraries, 3. System tools, 4. System services, 5. File system. These components work together to ensure the stable and efficient operation of the system, and together form a powerful and flexible operating system.
The 5 Essential Elements of Linux: ExplainedMay 07, 2025 am 12:14 AMThe five core elements of Linux are: 1. Kernel, 2. Command line interface, 3. File system, 4. Package management, 5. Community and open source. Together, these elements define the nature and functionality of Linux.
Linux Operations: Security and User ManagementMay 06, 2025 am 12:04 AMLinux user management and security can be achieved through the following steps: 1. Create users and groups, using commands such as sudouseradd-m-gdevelopers-s/bin/bashjohn. 2. Bulkly create users and set password policies, using the for loop and chpasswd commands. 3. Check and fix common errors, home directory and shell settings. 4. Implement best practices such as strong cryptographic policies, regular audits and the principle of minimum authority. 5. Optimize performance, use sudo and adjust PAM module configuration. Through these methods, users can be effectively managed and system security can be improved.
Linux Operations: File System, Processes, and MoreMay 05, 2025 am 12:16 AMThe core operations of Linux file system and process management include file system management and process control. 1) File system operations include creating, deleting, copying and moving files or directories, using commands such as mkdir, rmdir, cp and mv. 2) Process management involves starting, monitoring and killing processes, using commands such as ./my_script.sh&, top and kill.
Linux Operations: Shell Scripting and AutomationMay 04, 2025 am 12:15 AMShell scripts are powerful tools for automated execution of commands in Linux systems. 1) The shell script executes commands line by line through the interpreter to process variable substitution and conditional judgment. 2) The basic usage includes backup operations, such as using the tar command to back up the directory. 3) Advanced usage involves the use of functions and case statements to manage services. 4) Debugging skills include using set-x to enable debugging mode and set-e to exit when the command fails. 5) Performance optimization is recommended to avoid subshells, use arrays and optimization loops.
Linux Operations: Understanding the Core FunctionalityMay 03, 2025 am 12:09 AMLinux is a Unix-based multi-user, multi-tasking operating system that emphasizes simplicity, modularity and openness. Its core functions include: file system: organized in a tree structure, supports multiple file systems such as ext4, XFS, Btrfs, and use df-T to view file system types. Process management: View the process through the ps command, manage the process using PID, involving priority settings and signal processing. Network configuration: Flexible setting of IP addresses and managing network services, and use sudoipaddradd to configure IP. These features are applied in real-life operations through basic commands and advanced script automation, improving efficiency and reducing errors.
Linux: Entering and Exiting Maintenance ModeMay 02, 2025 am 12:01 AMThe methods to enter Linux maintenance mode include: 1. Edit the GRUB configuration file, add "single" or "1" parameters and update the GRUB configuration; 2. Edit the startup parameters in the GRUB menu, add "single" or "1". Exit maintenance mode only requires restarting the system. With these steps, you can quickly enter maintenance mode when needed and exit safely, ensuring system stability and security.
Understanding Linux: The Core Components DefinedMay 01, 2025 am 12:19 AMThe core components of Linux include kernel, shell, file system, process management and memory management. 1) Kernel management system resources, 2) shell provides user interaction interface, 3) file system supports multiple formats, 4) Process management is implemented through system calls such as fork, and 5) memory management uses virtual memory technology.
