【摘要】 从计算机集群系统实际应用出发,首先对Java线程的状态进行了分析,介绍了目前Java线程迁移机制的几种实现方法:处理源代码、处理字节码和扩展Java虚拟机的实现机制。从3个不同的方面进行了性能分析和比较,得出一个初步的评估。最后提出了一种扩展Java虚拟机方法的改进以及该迁移技术在集群系统中的应用。更多还原

【Abstract】 From the perspective of application requirement of the cluster,the state of Java thread is analyzed firstly.Some approaches to migration of Java threads are introduced,which are implemented by modifying application program at the level of source code,byte code,or by extending the Java virtual machine.These approaches are compared with each other from three different aspects to get a pre-liminary evaluation.A method-improved extending the Java virtual machine thread migration is presented,which is applied in a cluster system.更多还原
