MetaComputing with the IceT System

基于IceT系统的元计算这个项目的重点是异构网络上并发和分布式计算的新方法。提出的IceT系统建立在先前元计算技术的基础上，并扩展了这种高性能计算模式，将协作资源共享、进程移动性和代理技术结合在一起。资讯科技资讯网有助开发可携式的软件模块及应用组件，让使用者可自由交换；这些模块还可以用作修改或增强虚拟机（VM）特性的工具。这种由IceT促进的协作式元计算环境将在网络系统上提供高性能计算的传统优势，同时使重要的新兴分布式应用成为可能。我们提议的项目的一个核心活动将是调查动态合并和分裂虚拟机的问题，并根据所有者的约束开发分配池资源的机制。建议工作的第二个主要部分涉及创建计算基础设施，在该基础设施中，进程可以在远程位置上上传和软安装，在执行期间迁移，或作为代理传输到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，不仅允许字节码的移动，还允许本机编译的可重定位对象模块的移动，从而为计算密集型应用程序提供高效率。我们的主要工作部分将致力于设计和构建IceT中的移动流程基础设施，特别关注合并虚拟机中固有的资源管理和安全问题。

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.
