Scout: A Communications-Oriented, Compiler-Assisted Operating System

该项目涉及设计、实施和评价一个名为Scout的新操作系统，该系统旨在满足与国家信息基础设施相连的系统的要求。高级目标包括，以高带宽向应用程序可靠地交付数据，以及随着处理器数量的增加而增加的可伸缩性。Scout基于一种称为路径的抽象，它将网络通信扩展到主机操作系统中：资源分配、调度和故障隔离都是在路径基础上完成的。Scout将通过开发特定于操作系统的编译器技术来针对特定的操作系统优化应用程序，从而解决可伸缩性问题。该项目的两个主要交付物是Scout操作系统本身和用于开发新操作系统的工具集。

This project deals with the design, implementation and evaluation of a new operating system called Scout, which is designed to meet the requirements of the systems connected to the National Information Infrastructure. The high level goals include, reliable delivery of data to applications at high bandwidths, and scalability with increasing number of processors. Scout is based on abstraction called path which extends the network communication into the host operating system: resource allocation, scheduling and fault-isolation are done on a path basis. Scout will address the issue of scalability by developing operating system specific compiler technology to optimize applications to specific operating systems. Two main deliverables of the project are the Scout operating system itself and the set of tools for the development of new operating systems.
