摘要

本文研究了在主机pc上作为厚客户机实现的基于vm的移动计算系统中，如何临时使用免费本地存储来提高性能。我们使用术语TransientPC系统来指代这些类型的系统。我们提出的解决方案称为TransPart，它使用主机硬件的高性能本地存储来加速对性能至关重要的操作。我们的解决方案通过从主机的存储中借用空闲磁盘块，按需构建一个虚拟存储设备(我们称之为瞬时存储)。在本文中，我们介绍了一个TransPart原型的设计、实现和评估，它不需要修改主机的软件或硬件。实验结果证实，在提高用户体验的同时，TransPart具有较低的开销和启动成本。

Optimizing Storage Performance for VM-Based Mobile Computing

This article investigates the transient use of free local storage for improving performance in VM-based mobile computing systems implemented as thick clients on host PCs. We use the term TransientPC systems to refer to these types of systems. The solution we propose, called TransPart, uses the higher-performing local storage of host hardware to speed up performance-critical operations. Our solution constructs a virtual storage device on demand (which we call transient storage) by borrowing free disk blocks from the host’s storage. In this article, we present the design, implementation, and evaluation of a TransPart prototype, which requires no modifications to the software or hardware of a host computer. Experimental results confirm that TransPart offers low overhead and startup cost, while improving user experience.

期刊介绍： ACM Transactions on Computer Systems (TOCS) presents research and development results on the design, implementation, analysis, evaluation, and use of computer systems and systems software. The term "computer systems" is interpreted broadly and includes operating systems, systems architecture and hardware, distributed systems, optimizing compilers, and the interaction between systems and computer networks. Articles appearing in TOCS will tend either to present new techniques and concepts, or to report on experiences and experiments with actual systems. Insights useful to system designers, builders, and users will be emphasized. TOCS publishes research and technical papers, both short and long. It includes technical correspondence to permit commentary on technical topics and on previously published papers.
