摘要
千兆比特网络的到来使得由分布在不同地理位置的高性能机器和工作站组成的单一全国性虚拟计算机的实现成为可能。为了实现物理基础设施提供的潜力,必须开发易于使用的软件,支持应用程序代码中的大量并行性,并为用户管理底层物理系统的复杂性。Legion是弗吉尼亚大学(University of Virginia)的一个元系统项目,旨在为用户提供一个访问可用资源的透明接口,无论是在编程接口级别还是在用户级别。Legion解决了多语言环境中的并行性、容错性、安全性、自主性、异构性、资源管理和访问透明度等问题。在本文中,我们将介绍Legion的高级概述,它的愿景,目标,如何实现这些目标的简要概述,以及项目的当前状态。
The coming of giga-bit networks makes possible the realization of a single nationwide virtual computer comprised of a variety of geographically distributed high-performance machines and workstations. To realize the potential that the physical infrastructure provides, software must be developed that is easy to use, supports a large degree of parallelism in the application code, and manages the complexity of the underlying physical system for the user. Legion is a metasystem project at the University of Virginia designed to provide users with a transparent interface to the available resources, both at the programming interface level as well as at the user level. Legion addresses issues such as parallelism, fault-tolerance, security, autonomy, heterogeneity, resource management and access transparency in a multi-language environment. In this paper, we present a high-level overview of Legion, its vision, objectives, a brief sketch of how some of those objectives will be met, and the current status of the project.
