on the design of integrated developing environment for embedded parallel software 嵌入式并行软件的集成开发环境研究
ii ) the parallel computing of spectral element methods by element-by-element strategy is analyzed deeply, and we design a high-performance spectral element parallel software package named pses ?)将有限元方法中的逐元素(ebe)策略应用于谱元素方法的并行计算,在pc机群上设计实现了并行应用软件pses。
currently, parallel hardware technique is improved rapidly; but there are many problems in the design and realization of parallel software systems, such as the low development efficiency, the difficulty to ensure the quality and the poor portability 目前,并行硬件技术得到了迅速的发展;但是并行软件系统的设计和实现存在着开发效率低、质量难以保证和可移植性差等问题。
the conflict can be resolved by the parallel compute, but two questions exist at the same time . firstly, the related high rank parallel software is so scarce that the parallel computer can only used by the professional programmer 并行机的出现为复杂结构精细分析提供了硬件基础,但由于高层次并行软件的缺乏使得并行计算机往往只能由专业程序员使用,另外,并行机价格昂贵,不易普及。
it includes hardware technique, parallel software, parallel algorithm, etc . but the current international situation is that the development of parallel algorithm is far more behind parallel architecture . we are making the initial researches in many fields 研究一般的通用并行算法难度极大,而且在具体应用时,通常也不能直接使用,因此,针对具体体系结构的实际应用,进行并行算法研究可望得到较大的发展。
