基于校园网格的多学科计算及协同可视化

针对浙江大学各高性能计算资源过于分散、无法充分利用的问题,提出一种校园网格的架构.通过使用Globus Toolkit和Sun Grid Engine两种网格中间件,部署层次化结构的校园网格,并在此基础上提供科学计算、生物信息、流体力学等服务.通过在不同节点数的网格中的应用程序运行情况的测试,表明校园网格能够提供高效、稳定的计算能力.提供了在校园网格环境下本地绘制和服务器绘制两种可视化服务,用户可以针对不同的数据和计算环境,选择不同的可视化方法;用户可对可视化结果进行协同操作,便于联合研究和分析.

Multi-discipline computations and collaborative visualization on the campus grid

A campus grid is developed and deployed to integrate high performance computing resources in Zhejiang University.The architecture is based on a hierarchical combination of two grid middleware products,Globus Toolkit and Sun Grid Engine,in order to make use of their advantages.The campus grid is applied for scientific computation,bioinformatics,computational fluid dynamics,etc.Some test cases using Message Passing Interface(MPI) show that the campus grid can provide powerful and stable computing cycles.The campus grid also provides two collaborative visualization services,the local rendering and the server rendering,which can be customized by the user.Finally,the collaborative visualization service facilitates users to research and analyze cooperatively.
