摘要

本文介绍了一种通用的面向业务应用的n层分布式体系结构及其基本组件:分布在PC集群上的计算服务器。这种分布式服务器的设计与集群编程和业务标准都相关:它混合了TCP客户机-服务器机制、MPI编程和来自集群节点的数据库访问。本文研究的主要课题是基于MPI范式的通用分布式TCP服务器的设计，以及集群节点对数据库并发访问的实验和优化。最后，将这种新的分布式架构集成到工业Summit环境中，并实现了Hedge应用程序(一种著名的风险分析计算)，并在实验室和工业测试台上进行了性能测试。他们已经验证了该架构，显示出有趣的速度

A Generic Distributed Architecture for Business Computations. Application to Financial Risk Analysis

This paper introduces a generic n-tier distributed architecture for business applications, and its basic component: a computing server distributed on a PC cluster. Design of this distributed server is relevant of both cluster programming and business standards: it mixes TCP client-server mechanisms, MPI programming and database accesses from cluster nodes. The main topics investigated in this paper are the design of a generic distributed TCP server based on the MPI paradigm, and the experimentation and optimization of concurrent accesses to databases from cluster nodes. Finally, this new distributed architecture has been integrated in the industrial Summit environment, and a Hedge application (a famous risk analysis computation) has been implemented and performances have been measured on laboratory and industrial testbeds. They have validated the architecture, exhibiting interesting speed up
