项目摘要

(Experiments on Asynchronous Parallel Computational Mechanics) R. Shioya visited Georgia Inst. of Tech., and had a meeting with Prof. S. N. Atluri and Dr. H. Kawai. He performed experiments on parallel finite element analyses of domain decomposition using multiple computers both in Univ. of Tokyo and Georgia Inst. of Tech. Then, the algorithm was improved to take ininto account heavy imbalance in network performance, and further experiments on FE problems of 100 millions DOFs were performed using computers in Univ. of Tokyo, Georgia Tech, Greenwich Univ. (UK) and GMD (FRG). H. Okuda also visited Georgia Tech. and performed asynchronous experiments on computational fluid dynamics.(Investigation of Network Cluster Computing) T. Horie visited US, and investigated this issue, Network performance is increasingly important in parallel computational mechanics.(Investigation of Object-oriented parallel computational mechanics) M. Miki visited US, and investigated an object-oriented approach, w … More hich is expected to be a main stream of autonomous computational mechanics.Researches on high-performance parallel computational mechanics in a heterogeneous computer environment begin performed in US, Europe and Asia have been investigated, and experiments on large-scale asynchronous parallel computational mechanics simulations were performed using multiple computers in Japan, US and Europe through the Internet.(Investigation of Large-scale Analysis) G. Yagawa visited Austria, and investigated meshless parallel computational mechanics.(investigation of parallel computational mechanics in Asia) G. Yagawa and S. Yoshimura visited Hong Kong, and T. Furukawa visited Hong Kong and P. R. China, and investigated latest researches on parallel computational mechanics. Few high-performance parallel computers are available in Asia, and researches on parallel processing have just started recently. On the other hand, PC cluster and WS cluster are expected to be popular as parallel computing environments on Asia, and thus asynchronous parallel computational machanics in highly demanded. Less

Okuda还访问了佐治亚理工学院。并在计算流体动力学上进行了异步实验。（网络群集计算的研究）T。Horie访问了我们，并研究了这个问题，在平行计算机械学中，网络性能越来越重要。已经研究了在美国，欧洲和亚洲进行异质计算机环境中的高性能平行计算机制，并且已经通过日本，美国和欧洲在日本，美国和欧洲进行多台计算机进行大规模异步平行计算机制模拟的大规模异步平行计算机械学模拟的实验。亚洲的力学）G。Yagawa和S. Yoshimura访问了香港，T。Furukawa访问了香港和P. R. Chine，并研究了有关平行计算技师的最新研究。亚洲很少有高性能平行的计算机可用，并且对并行处理的研究刚刚开始。另一方面，PC群集和WS群集有望在亚洲的平行计算环境中流行，因此在高度需求中的异步并行计算机化。较少的
