In contrast to disk or flash based storage solutions, throughput and latency of in-memory storage promises to be close to the best performance. Kove®’s XPD® offers pooled memory for cluster systems. However, the system does not expose access methods to treat the memory like a traditional parallel file system that offers POSIX or MPI-IO semantics. Contributions of this poster are: 1. Implementat...

As the access control mode of notepad files cannot meet requirements risk for sensitive file hierarchical access, this paper proposes an application classification-based detection method abnormal to files. The classification and classification, policy mapping, basic preset are designed. Combining operating system’s identification different applications at runtime, we monitor by applications. cr...

AWavelet tree is a data structure adjoined to a file that has been compressed by a variable length encoding, which allows direct access to the underlying file, resulting in the fact that the compressed file is not needed any more. We adapt, in this paper, the Wavelet tree to Fibonacci Codes, so that in addition to supporting direct access to the Fibonacci encoded file, we also increase the comp...

The paper presents the design of an I/O balancing file system on Web server clusters. High-speed networks allow machines to access remote data nearly as quickly as they can access local data. This trend motivates the introduction of I/O balancing mechanism into cluster file systems. Two effective approaches are issued in the paper: file migration and unique cache. The former is to migrate the f...

Recent advances in computing and communication technologies have made it technically feasible and economically viable to provide on-line access to a variety of information services over high speed networks. Particularly, convergence of various technological factors, namely in network access and in video coding and transmission, have recently brought a rapid growth of interest in on-line access ...

Introduction: The aim of this study was to compare digital and conventional radiography in determining the working length of dilacerated canals.Methods: Thirty nine human extracted single-rooted teeth with root curvature more than 35 degrees were included in this study. After access preparation, a file was inserted into the canal and advanced until the file tip was visualized at the foramen. Wi...
