摘　　要：文中介绍了ＰＪＶＭ（ｐａｒａｌｅｌＪａｖａｖｉｒｔｕａｌｍａｃｈｉｎｅ）系统的组成及主要特点，讨论了如何扩充Ｊａｖａ的对象库，解决异构环境下进行并行分布处理出现的多进程或多线程存取共享变量的同步、分布式共享存储管理等问题．并通过几个实例说明了系统提供的多种编程接口和多种计算模式是可行的，从而为Ｊａｖａ应用开辟了新的领域，为在异构广域网络上实现超大问题的大规模分布并行处理奠定了基础．First introduced is the main characteristics of PJVM(parallel Java virtual machine),and then addressed are some key issues such as synchronous problem among multi threads and the implementation of distributed sharing memory when expanding Java object libraries to support distributed parallel computing and processing on heterogeneous networks.Some examples are also presented in order to evince that the multiple programming interfaces and computing modes provided by PJVM are feasible. All of these indicate that PJVM opens up a new realm for Java application and lays down foundation for large scale parallel processing on massive problems on heterogeneous world wide networks such as Internet.
