摘要

最近的64位微处理器已经为程序提供了一个巨大的18.4万亿字节的地址空间。这导致了操作系统的设计，它提供了一个单一的虚拟地址空间，所有代码和数据都驻留在其中，并且跨越了分布式系统的所有存储级别和所有节点。这些被称为sasos的操作系统具有可用于支持分布式系统中的同步和一致性的特性，这些特性提供了改进的程序开发环境和比传统操作系统更高的性能。Sombrero，我们的SASOS设计，利用其硬件支持对象粒度保护，独立线程相关的保护域和隐式保护域交叉，为基于库存处理器的SASOS无法提供的分布式对象复制集管理提供同步和一致性支持。它的设计为面向对象编程提供了直接的系统级支持，包括许多针对现代分布式计算的系统架构特性。

Using a single address space operating system for distributed computing and high performance

Recent 64-bit microprocessors have made a huge 18.4 quintillion byte address space potentially available to programs. This has led to the design of Operating Systems that provide a single virtual address space in which all code and data reside in and that spans all levels of storage and all nodes of a distributed system. These operating systems called SASOSs, have characteristics that can be used to support synchronization and coherency in a distributed system in ways that provide an improved program development environment and higher performance than that available from conventional operating systems. Sombrero, our SASOS design, makes use of its hardware support for object-grained protection, separate thread related protection domains and implicit protection domain crossing to provide synchronization and coherency support for distributed object copy set management not available in SASOSs built on stock processors. Its design, which provides direct system level support for object oriented programming includes a number of system architectural features targeted at modern distributed computing.
