Problems solved by technology

In research institutes and enterprises, there are usually dedicated private clusters for CFD simulation calculations. The storage method of the result data is usually copied and taken away by the simulation engineer using a separate mobile storage device, or the results are analyzed after downloading in the local area network. The time limit for local area downloads is usually very short, and the resulting files will be quickly overwritten by other calculations

Abstract

The invention is a cluster-based distributed PB-level CFD simulation data management system. The invention relates to the technical field of simulation data management. The system hardware of the invention is mainly divided into two parts, a client and a server, which are connected to the Internet through a router. The client is composed of multiple clients and routers. The client is a man-machine port that directly interacts with the user. It is responsible for sending the user's instructions to the server and presenting the results returned by the server to the user. Even if a certain part of data is lost in the present invention, other data is still available, and data generation (computation) and storage are all completed in the cluster, making full use of the resources of the cluster machine, splitting large-scale data into small data, and effectively utilizing the idle resources of the disk . It can support multiple engineers to access data at the same time, reducing the data flow time and enabling immediate access to the data after calculation, which is more time-sensitive.

Description

technical field [0001] The invention relates to the technical field of simulation data management, and is a cluster-based distributed PB-level CFD simulation data management system. Background technique [0002] With the improvement of computer computing power, especially the application of supercomputers such as Tianhe and Taihu Lake in the field of CFD, the data volume of CFD simulation results has also soared rapidly, and the data volume of a single calculation reaching TB level has gradually become the norm. . The huge amount of data has exceeded the storage capacity of a single computer, and the present invention proposes a cluster-based distributed PB-level CFD simulation result data management system. On the one hand, it provides an efficient data storage and retrieval method, and on the other hand, it can make full use of the idle storage resources of the cluster. [0003] In scientific research institutes or enterprises, when performing engineering-level CFD simul...
