摘要

介绍了一种用于工作站网络中分布式科学计算应用的CORBA负载分配服务的设计与实现。所提出的方法基于将负载分配集成到CORBA命名服务中，而CORBA命名服务又依赖于为典型的网络化Unix工作站环境开发的底层WINNER资源管理系统提供的信息。描述了命名服务的必要扩展、用于收集负载信息的WINNER特性和放置决策。给出了整个系统的原型实现，并讨论了数学测试函数并行优化的性能结果。

Load distribution in a CORBA environment

The design and implementation of a CORBA load distribution service for distributed scientific computing applications running in a network of workstations is described. The proposed approach is based on integrating load distribution into the CORBA naming service which in turn relies on information provided by the underlying WINNER resource management system developed for typical networked Unix workstation environments. The necessary extensions to the naming service, the WINNER features for collecting load information and the placement decisions are described. A prototypical implementation of the complete system is presented, and performance results obtained for the parallel optimization of a mathematical test function are discussed.
