摘　　要：采用并行计算可以提高凝固模拟软件运行性能,缩短凝固模拟所需时间。OpenMP是一种已被广泛接受、用于共享存储编程的工业标准。本研究在双核心微机平台上使用OpenMP编译指导语句实现了华铸CAE软件中凝固过程数值模拟的并行计算,并对其并行性能进行了测试和分析。实际应用证明该方法能获得较高的加速比,加快了计算速度。Using parallel computation can enhance the performance of numerical simulation of solidification software and get great runtime reductions. OpenMP is an industrial standard which is used in shared memory parallel programming. The method using OpenMP directives has been studied to parallelize the simulation of solidification on a microcomputer with double-core processor in InteCast CAE software. Then, the performance of OpenMP programs has been tested and analyzed. The parallelized code is indicated to be practical in achieving high speedup and great runtime reductions.
