Abstract

The GridRPC model (Nakada et al., 2003) is an emerging standard promoted by the Global Grid Forum (GGF) that defines how to perform remote client-server computation on a distributed architecture. In this model data are sent back to the client at the end of every computation. This implies unnecessary communications when computed data are needed by another server in further computations. Since, communication time is sometimes the dominant cost of remote computation, this cost has to be lowered. Several tools instantiate the GridRPC model such as NetSolve which is a NES environment developed at the University of Tennessee, Knoxville. In this paper, we present the modifications we made to the NetSolve protocol in order to overcome this drawback. We have developed a set of new functions and data structures that allow clients to order servers to keep data in place and to redistribute them directly to another server when needed.

基于数据持久化和再分配的GridRPC模型改进
GridRPC模型(Nakada et al., 2003)是由全球网格论坛(GGF)推动的一个新兴标准,它定义了如何在分布式架构上执行远程客户机-服务器计算。在这个模型中,数据在每次计算结束时被发送回客户端。这意味着当另一台服务器在进一步计算中需要计算数据时,会产生不必要的通信。由于通信时间有时是远程计算的主要成本,因此必须降低该成本。有几个工具实例化了GridRPC模型,比如NetSolve,它是田纳西州诺克斯维尔大学开发的一个NES环境。在本文中,我们提出了我们对NetSolve协议所做的修改,以克服这一缺点。我们开发了一组新的函数和数据结构,允许客户端命令服务器将数据保存在适当的位置,并在需要时将它们直接重新分发到另一台服务器。
