Integrating Portable and Distributed Storage
نویسندگان
چکیده
We describe a technique called lookaside caching that combines the strengths of distributed file systems and portable storage devices, while negating their weaknesses. In spite of its simplicity, this technique proves to be powerful and versatile. By unifying distributed storage and portable storage into a single abstraction, lookaside caching allows users to treat devices they carry as merely performance and availability assists for distant file servers. Careless use of portable storage has no catastrophic consequences. Experimental results show that significant performance improvements are possible even in the presence of stale data on the portable device.

Energy-Efficiency and Storage Flexibility in the Blue File System
A fundamental vision driving pervasive computing research is access to personal and shared data anywhere at anytime. In many ways, this vision is close to being realized. Wireless networks such as 802.11 offer connectivity to small, mobile devices. Portable storage, such as mobile disks and USB keychains, let users carry several gigabytes of data in their pockets. Yet, at least three substantia...
متن کاملIntegrating Ontology Storage and Ontology-based Applications Through Client-side Query and Transformations
This paper investigates the integration of ontology storage and ontology-based applications through the example of the EnerSearch case study conducted within the On-To-Knowledge research project. We look at the problem of integrating the Sesame storage and query facility with its client application and identify both functional and technical needs for a new software package for client-side query...
متن کاملPersistent Storage and Querying of Compressed Xml Documents on the Web
We describe the design and implementation of a Web-based distributed system called TREESTORE, intended for storing compressed XML documents in a relational database. The use of a database is fully portable, requiring minimal changes to application code to substitute one database management system for another. In TREESTORE, compressed XML documents are shredded into a fixed number of relational ...
متن کاملOptimization of the PCM-integrated solar domestic hot water system under different thermal stratification conditions
Many researchers have investigated how to increase the overall efficiency of solar-driven thermal systems. Several key parameters, such as collector efficiency and storage tank characteristics, may impose some constraints on the annual solar fraction (ASF) of such systems. In this paper, the behaviour of integrating the phase change material (PCM) in SDHW systems is modelled and optimized n...
متن کاملUser Interfaces for Portable Proofs
Portable proofs are a new and interesting way of integrating theorem provers into distributed environments like the web. This article reports on user interface’s challenges and opportunities for theorem provers in such environments. In particular, this article reports on the design of user interfaces used for searching, browsing and inspecting TSTP problems when published as portable proofs.
