摘要 在电磁计算领域,一些单机版仿真软件处理大批量电磁计算时速度过慢,然而网络版仿真软件价格又过于昂贵。为了提高效率并节省成本,构建了一种分布式电磁计算仿真平台,可用来辅助单机版仿真软件工作,弥补其不足。仿真平台采用双客户端/服务器的软件体系结构,利用优先数法和先来先服务法相结合的算法进行作业调度,并且通过多种接口实现与不同的仿真软件通信。最后,通过一组求同轴至矩形波导转换接头传输函数的算例分析了不同集群规模下的计算所用时间。结果表明,利用仿真平台,可以大大提高计算效率。 In electromagnetics,existing stand-alone simulators are very slow to do batch tasks while network based simulators have high prices.In order to improve the efficiency and save the cost,a distributed simulation platform for electromagnetic computing was constructed in this paper to make up their disadvantages.Based on the double client/server software architecture,the simulation platform used an improved algorithm combining priority with FCFS to do job scheduling,and kept communication with various simulators through different interfaces.Finally,a simple example was carried out to solve the transfer function of a coaxial-rectangular waveguide converter and then analyze the computing time at different cluster scale.The numerical result indicated that the platform was effective.
