摘要: 鉴于连铸结晶器内数值模拟计算量大、耗时较长、传统串行算法很难满足现代工业要求的特点,提出了基于MPI的并行算法,该算法通过数据空间分块、各功能模块划分计算的方法对模拟的SIMPLER算法进行并行化。通过在上大自强3000集群高性能并行计算环境下的数值实验表明,该算法取得了较好的并行计算效果。

Abstract: As the numerical simulations in the continuous casting mould is characterized as high cost of calculation, time-consuming and the traditional serial algorithm is hard to meet the demand of the modern industry, MPI-based parallel algorithm is studied in this paper. The parallel algorithm of continuous casting simulation based on data-division and function-partition is given for SIMPLER algorithm. Through the result of the experiment on the Ziqiang 3000 high performance cluster computation environment, it is proved that the parallel algorithm has good parallel performance.
