摘要

数值模拟用于解决重大的科学和工程问题。高性能数值仿真可以分为并行仿真和分布式仿真两大类。本文利用消息传递接口(Message Passing Interface, MPI)和Magpar软件对微磁问题的并行仿真性能进行了统计研究。描述了总时间、初始化时间、解析时间、内存和带宽使用的结果，这些结果取决于处理器的数量。

Performance analysis and optimization of a paralell numerical code for micromagnetic calculus

Numerical simulations are used for solving significant scientific and engineering problems. High performace numerical simulations can be divided in two categories: parallel and distributed simulation. In this paper we make a statistical study of performances in parallel simulation using Message Passing Interface (MPI) and Magpar software for micromagnetic problems. The results of total time, initialization time, resolving time, memory and bandwidth used depending on the number of processors are described.
