This thesis mainly focuses on the multi - level parallelism development and performance optimization of scientific programs on this architecture, and our works are summarized as follows. ( 1 ) we put forward the multi - level parallel computing time model, which is suitable for smp cluster to analyze program performance from the micro - aspect. we also provide a multi - level parallel optimization speedup model based on the single - processor speedup factor, which can evaluate program performance from three parallel levels and guide us to improve the programs
本文圍繞這種多級并行體系結構中的超節點級、節點級和單機指令級三個層次的并行性開發與優化，在科學計算程序的綜合優化技術研究方面做了以下的工作與創新: （ 1 ）針對smp集群體系結構提出了多級并行計算時間模型，用於程序性能的微觀分析;將單機處理速度與加速比統一起來，提出了基於單機優化加速因子的多級并行優化加速比評價模型，該模型分別從三個并行層次的角度出發對程序性能進行評價，並指導對程序的改進與優化。 -
The 3d turbulent flow fields around high - speed trains of four kinds of model uain have been calculated by 3d parallel compute program coded with the algorithms presented in this thesis. from the calculation results, the aerodynamic drag of different types of model trains are obtained, some characteristics of the flow field over the high - speed train are analyzed preliminarily such as pressure distribution and diversification, velocity distribution and diversification, and the affections of different train head shape to pressure. velocity, pressure gradient and the like
