Method for deploying and sharing NFS (network file system) automatically and quickly

Abstract

The invention provides a method for deploying and sharing an NFS (network file system) automatically and quickly. On the basis of Shell Script, the interactive environment is provided, test parameters and a performance reference table required by the Lin Pack can be acquired simply conveniently by only inputting cluster configuration parameters according to prompts, the theoretical floating-point peak value and the actual floating-point peak value can be acquired by the Lin Pack, concurrency efficiency of the system can be further determined and the purpose of evaluating the cluster system quickly is achieved. A deployer only needs to place scripts and files required by deployment on management nodes, writes host names of all nodes (management nodes and computing nodes) into a host file, writes to-be-shared directory names into a share_dir file, runs the install.sh by a root user on the management nodes, inputs the root passwords, so that sharing and deployment of the NFS of all nodes can be completed and are still available in the next starting.

Description

technical field [0001] The present invention relates to the deployment of NFS (Network File System) in a Linux cluster environment. Specifically related to the automatic rapid deployment of NFS (Network File System) based on shell script and expect automatic response function. Background technique [0002] High-performance computing (HPC) usually uses many processors. In high-speed Internet, parallel computing environments such as MPI are used to run parallel computing software to accelerate the efficiency of scientific computing. With the popularization of HPC in universities and research institutes, the establishment of a large-scale cluster system with high parallel efficiency is of great significance to scientific research, education, national defense and other undertakings. Therefore, it is very important to quickly and effectively evaluate the performance of a cluster system to establish a large-scale cluster system with high parallel efficiency. [0003] An importan...

AI Technical Summary

Problems solved by technology

[0005] In the traditional LinPack test, several test parameters (such as the most important N (problems sizes)) need to be determined according to the specific cluster environment. People who are not familiar with theoretical knowledge can easily calculate wrong parameters and cause the entire test to fail.

At the same time, after testing the highest peak value of actual computing, it is quite complicated to evaluate the performance of the entire system based on the results
