Metacomputing with the IceT SystemThe focus of this project are novel methodologies for concurrent and distributed computing on heterogeneous networks. The proposed IceT system builds upon prior work in metacomputing technologies and extends this mode of high performance computing to incorporate cooperative resource sharing, process mobility, and agent technologies. IceT facilitates the development of portable software modules and application sub-components that are freely exchangeable among users; these modules may also be used as vehicles for modifying or enhancing virtual machine (VM) characteristics. Such a cooperative metacomputing environment facilitated by IceT will provide the traditional benefits of high performance computing on networked systems while enabling significant new and emerging distributed applications. A core activity of our proposed project will be to investigate issues in dynamic merging and splitting of virtual machines and developing mechanisms to allocate pooled resources in accordance with owners' constraints. The second major portion of the proposed work involves the creation of a computational infrastructure in which processes may be uploaded and soft-installed at remote locations, migrated during execution, or travel as an agent to several parts of the VM. The basis for this model in IceT is the Java language. IceT builds a complete runtime system upon Java facilities to allow movement not only of bytecode, but also natively compiled relocatable object modules, thereby enabling high efficiencies for compute-intensive applications. A major portion of our effort will be devoted to designing and constructing the mobile process infrastructure in IceT, with particular focus on resource management and security issues inherent in merged virtual machines.

该项目的重点是异构网络上并发和分布式计算的新方法。建议的IceT系统建立在元计算技术的先前工作，并扩展这种模式的高性能计算，将合作资源共享，进程的移动性，和代理技术。IceT促进了可移植软件模块和应用程序子组件的开发，这些模块可以在用户之间自由交换;这些模块也可以用作修改或增强虚拟机（VM）特性的工具。这种由IceT推动的协作元计算环境将在网络系统上提供高性能计算的传统优势，同时实现重要的新的和新兴的分布式应用。我们建议的项目的一个核心活动将是调查虚拟机的动态合并和拆分问题，并根据所有者的约束条件开发分配池资源的机制。拟议工作的第二个主要部分涉及创建一个计算基础设施，其中进程可以在远程位置上传和软安装，在执行期间迁移，或作为代理旅行到VM的几个部分。IceT中这个模型的基础是Java语言。IceT在Java设施上构建了一个完整的运行时系统，不仅允许移动字节码，还允许移动本机编译的可重定位对象模块，从而为计算密集型应用程序提供高效率。我们的主要工作将致力于设计和构建IceT中的移动的流程基础设施，特别关注合并虚拟机中固有的资源管理和安全问题。
