基于对象的可靠群组通信机制研究

近年来,网格计算技术日益成为用来解决数据和计算密集型应用的可行方案,网格运行平台本身和在网格环境中的并行应用都需要大量的点对多点的群组通信.提出一种灵活、可容错的群组通信机制.该机制基于远程方法调用(RMI),可为分布式并行应用提供高效、可容错的群组通信.通信方法可以在本地对象、远程对象,或一组对象中激活.这种通信采用异步方式,通信发起者可以选择全等待或必要性等待两种机制来获取通信结果.从而最大程度地保证通信的可靠性或高效性.

Research of reliable object-based group communication

Grid computing is emerging in recent years as a viable computing paradigm to solve data and computing-intensive distributed applications.Point-to-multipoint communication,which is well known as group communication,is required for both grid platform itself and parallel applications running in the grid environment.Group communication technology is a necessary technology in parallel computing.A more flexible and fault-tolerant group communication mechanism was built on top of Remote Method Invocation(RMI).It c...
