基于网格计算技术的高性能计算解决方案及其实现

随着信息时代科学技术的突飞猛进,科学技术的发展不断对高性能计算机界提出更高更多的挑战,如超级计算能力、海量数据、计算周期长等等。网格计算技术的出现和发展使得解决科学工程计算提出的问题和挑战成为可能。基于网格计算技术,文章提出了一种高性能计算的解决方案。该方案从不同程度上解决了科学工程计算提出的多个问题。同时,笔者利用网格计算技术的一个主流实现-GlobusToolkit(Release2.4)和其他Internet技术,在北京大学校园网内跨越若干个局域网,搭建了一个科学工程计算网格,实现了提出的解决方案。在这个计算网格上进行了几个科学计算的实例,并取得了满意的效果。实际应用表明这个计算网格是可行的,具有很强的实用价值。

A Grid-Computing-Based Solution to High Performance Computing and its Implementation

With the rapid development of science and technology in the information era,science&engineering compu-tation has introduced to the field of high performance computing higher and more demands,namely,super computation capabilities,large quantity of data,over long period of calculation course,etc.The fast growth of grid technologies brings about the possibility of resolving the above -mentioned challenges and demands.The paper,based on grid computing technology,presents a solution to high performance computing.The solution addresses key issues of science&engineer-ing computation.Meanwhile,we utilize Globus Toolkit(Release2.4),one of the major implementations of grid computing,together with other Internet techniques,as middleware,and establish a grid for science&engineering computing across several LANs in Peking University campus network.Some samples of science&engineering computing run on this grid produce satisfactory results.Application experiences demonstrate its feasibility and practical utility.
