CORBA事件服务及其在分布式并行计算中的应用

1 引言随着网络技术的飞速发展和日益完善,分布式并行程序设计已经成为软件开发的主流技术之一。在分布式并行计算环境中,异构分布式环境中资源的透明存取和系统中各个异构节点间的通信问题是一个主要问题。OMG提出的CORBA规范,能很好地解决异构系统中面向对象的应用之间的通信问题,因此CORBA适合作为分布式并行应用程序的中间件。 CORBA的基本通信模型是同步通信,而在分布式并

CORBA Event Service and it''''s Application in Distributed Parallel Computing

The Common Object Request Broker Architecture (CORBA) is a main specification applied to the dis-tributed parallel program design at present. It includes many services, in which Event Service can provide the asyn-chronous communication model for the distributed parallel program design. This paper introduces the Event Service ofCORBA, then designs and implements a distributed parallel model based on Event Service. This model is made to im-plement overlap of the computing and communication , to reduce the unnecessary time for waiting and enhance theparallel effect. The paper also shows the practical application of the model with an example of the distributed parallelmatrix multiplication.
