The combination of scaling parallel computing technologies and numerical weather forecasting research results is of great significance to develop the high performance parallel computer application , to improve the numerical weather forecasting level , and to advance the parallel computer study 可扩展并行计算技术与数值气象领域研究成果相互渗透,对发展高性能并行计算机的应用、提高数值气象预报水平、促进并行计算机的研制,具有极为重要的意义。
Therefore , the design of high performance interconnection network is important to the improvement of high performance parallel computer . the " effect of the bottle - neck " of electronic interconnection network limits operation speed , clock skew and interconnection bandwidth constraints , which can not be dealed with through technology 电互连网络不仅存在着“瓶颈效应” 、运算速度有限、时钟歪斜、互连带宽受限等问题,而且从工艺上也是无法解决的。
Cellular element method is a new numerical computing method . in this method the integer analysis of structure is changed into a series of part analysis by using the idea of cellular automata . it may have a good future in the aspect of large structure because it hardly have any special request on the capability of computer . simultaneity , it can be developed into a high parallel arithmetic to suit for the request of parallel computer in the future 元胞单元法是新近出现的一种数值计算方法,它引用元胞自动机的思想将有限元对结构的整体分析变成局域求解,对计算机容量要求低,在大型复杂结构的计算方面具有良好的前景,同时可望形成一种高度并行的算法,适用于未来并行机的要求,是一种富有发展潜力的新的数值方法。
Ii ) we organize the parallel computing of ' the third generation ocean general circulation model from the chinese institute of atmosphere physics ( lasg / iap ) , and we also apply several parallel optimization strategies including multi - overlapping - boundary . the parallelism is implemented both on distributed memory and shared memory parallel computers , based on the spitting of latitude zones . this parallel ocean general circulation model is the first one in china 11 )发展了国内第一个高效并行海洋环流模式:深入研究了中国科学院大气物理所第三代海洋环流模式,分析了其串行计算特点和并行可扩展性,指出了其计算方法上存在的对并行计算的某些限制,对该模式组织了有效并行计算,并成功应用了包括多重叠边界在内的若干并行优化方法,在国产小型mpp系统和sgioriginzoo 。
