PYI: High Performance Operating Systems

本研究主要针对单处理器和多处理器的高性能操作系统进行研究。架构和编程技术这两个与操作系统接壤的领域，在过去十年里发生了根本性的变化。不幸的是，操作系统对这些变化的反应很小。因此，总体系统性能的增长速度远远低于这两个领域的进步所能预测的速度。三个基本问题是进程间通信、虚拟内存管理和分布式内存并行编程。其目标是使操作系统技术与现代架构和现代编程系统步调一致。

This research focuses on high performance operating systems for uniprocessors and multiprocessors. Architecture and programming technology, the two fields which border operating systems, have undergone radical changes in the last ten years. Unfortunately, the reaction of operating systems to these changes has been slight. Consequently, overall system performance is growing much less quickly than advances in either of these areas would lead one to predict. Three fundamental issues are interprocess communication, virtual memory management, and distributed memory parallel programming. The goal is to bring operating systems technology into step with modern architecture and modern programming systems.
