气动计算软件集成系统中的远程控制

Remote Control in Aerodynamic Calculating Software Integrated System

随着我国航空航天技术的飞速发展,气动计算软件集成技术日趋成熟,但用户在并行计算中需要手动输入的操作较多。鉴于此,通过编程开发了基于TCP/IP协议的FTP客户端应用程序,实现了对网格文件的信息采集、过滤并将其和参数、脚本文件等批量自动上传的功能。根据批处理文件中的命令,调用Windows平台自带的客户端Telnet,向远程集群管理节点发出命令,远程启动服务器集群的并行计算任务。最后,在客户端实现了远程控制服务器集群上的计算流体力学软件Fluent进行并行计算。结果表明:使用该远程控制系统能够减少用户输入操作,提高计算效率,保证数据的实时更新。

With the speedy development of aviation and space technology, the aerodynamic integrated caculating software is becoming mature, but the users need to enter more operations manually in the parallel computation. Therefore, an applied program of FTP client which bases on the TCP/IP protocol is developed, the function of the information collection and filtering of the mesh data files are realized, which are uploaded automatically in quantity etc. According to the commands in the batch file, the commands are sent to the managing node of the remote cluster and parallel computational tasks of the servers are booted up remotedly by calling the client Tel- net, which belongs to the Windows platforms. Finally the computational fluid dynamics software Fluent is taken, which could control server remotely as an example in the client to do parallel computation. The results show that the users can effectively reduce their input operations, improve computing efficiency, and ensure real- time updates by using the remote control system.
