微机群并行计算机安全开机系统的研发

Study on Safety Switching System of PC-Cluster Parallel Computer

随着计算机技术的飞速发展,并行计算机用户环境的设计日益成为一个至关重要的问题;并行计算机用户环境的优劣将直接影响到高性能计算机的发展和应用;论文就MPMD型微机群并行计算机的开机方式进行了有意义的改进;MPMD型微机群并行计算机在开启时,需经人工按压开关开启各个节点,多达64个;改进后系统利用MCS-51单片机系统,在实验的基础上确定了开启节点的最佳时间段,实现了利用微处理器开启多节点的程控开关,可方便地实现了多节点的自动安全连续启动。

With the fast development of computer technology, the design of user＇s environments of computer is a challenging problem. It is user＇s desktop for parallel computer. The quality of usel＇s environment will impact the development and application of high performance machines. In this paper the switching system for MPMD type PC--clusters parallel computer is studied and some technical problem is improved. In the absence of MPMD type PC--clusters parallel computer power--on, it should be subject to push the button of switches and open the all nodes one by one, from 1 to 64 nodes. The program--controlled switches system is implemented by using the MCS-51 MCU on the basis of experiments to determine the best time to open the nodes. It became easier to start many nodes automatically and safely.
