为对大规模异构机群系统进行管理,设计并实现了一套负责机群内部节点之间通信的消息中间件ACMSCom。这种消息中间件使用可扩展标记语言(XML)作为数据传输的媒介,具有平台无关、操作系统无关和语言无关的特性,它可以以同步方式和异步方式进行数据交换,从而满足不同情况下机群节点间通信的要求。该中间件在机群中的实际运行结果表明,该系统在同步通信方式下有较好的性能。这套系统还可以用来解决其他大规模异构分布式系统内部的通信问题。
In order to manage the large-scale heterogeneous cluster system, we designed and implemented a set of message middleware ACMSCom responsible for the communication among nodes in the cluster. This message middleware uses Extensible Markup Language (XML) as the medium for data transmission. It has platform independence, operating system independence and language independence. It can exchange data synchronously and asynchronously to meet the needs of different groups Requirements for communication between nodes. The actual operation of the middleware in the cluster shows that the system has better performance under the synchronous communication mode. The system can also be used to solve communication problems within other large-scale heterogeneous distributed systems.
