摘要
网络并行计算是当今并行计算发展的新方向。在网络并行环境下探讨了并行遗传算法进行结构优化设计及其算法的实现方法。并在四台 PC 机组成的网络平台上,进行了钢屋架结构优化设计的数值测试。计算结果表明,设计的并行算法在网络并行计算环境中具有较高的加速比和效率,同时验证了并行遗传算法用于结构优化是可行的和有效的。
Nowadays the network-based parallel computing has become a new trend of parallel computing. The network-based parallel genetic algorithm for structural optimization is discussed. The test of truss optimization design is done on the network system consisting of four personal computers. The calculating results indicate that the designed parallel algorithm has high speedup and efficiency; and illustrate the feasibility and validity of the given method in structural optimization.
