二维三温能量方程求解 MPI-OpenMP 并行算法研究
Research of hybrid MPI-OpenMP parallel algorithm for solving two dimensional three temperatures energy equation
摘要
Abstract
The solution of two dimensional three temperatures energy equation is one of the core issues of inertial confinement fusion.Now the existing parallel algorithm and software package is useless as the size of ICF becoming bigger and bigger.This paper designed the hybrid parallel algorithm of MPI-OpenMP for solving the 2-D 3-T energy equation,which used the MPI processes to handle communication and employ the OpenMP multi-threads to do the core computation.The hybrid parallel al-gorithm can not only accommodate the large problem,but also have good performance.The experiment show that the algorithm can obtain 39.53 times speedup by using 48 processes and 1 92 threads while the scale of problem reaches 1 06 .And with the increase of number of processor,the speedup ratio of the model improves more significantly.关键词
