项目摘要

Grid Computing is a term originated from "Power Grid". The idea is that the computing power is provided on the demand and supply base so long as the computing fee will be paid. World Wide Web services are limited to those of information. On the other hand, Grid computing will provide total cooperative services that users can benefit including computing power, visualization, information, and sensing. Grid computing will also include an idea including sharing files and applications over wide area networks. We present our parallel Partic-In Cell simulation experiment based on Computational Grid system on the academic high performance network SuperSINET. Computational Grid system consists of three computer nodes on SuperSINET, which configured with the Clobus Toolkits and MPICH-G2. In our experiment, we first conform the scalability of the parallel PIC simulation code on this wide area Grid system. After we analyze the results and find that the bottleneck point exist on the communication across the network, we successfully make use of some features in Globus toolkit and MPICH-G2 to improve the computational efficiency across the network.

网格计算这个术语起源于“Power Grid”。这个想法是，只要支付计算费用，就可以根据需求和供应基础提供计算能力。万维网服务仅限于信息服务。另一方面，网格计算将提供用户受益的整体协同服务，包括计算能力、可视化、信息和感知。网格计算还将包括通过广域网共享文件和应用程序的想法。我们在学术高性能网络 SuperSINET 上展示了基于计算网格系统的并行 Partic-In Cell 模拟实验。计算网格系统由SuperSINET上的三个计算机节点组成，配置了Clobus工具包和MPICH-G2。在我们的实验中，我们首先在这个广域网格系统上验证并行PIC仿真代码的可扩展性。在分析结果后发现整个网络的通信存在瓶颈点，我们成功地利用Globus工具包和MPICH-G2中的一些功能来提高整个网络的计算效率。
