Abstract:
This paper presents DSM64: a lazy release consistent software distributed shared memory (SDSM) system built entirely in user-space. The DSM64 system is capable of executing threaded applications implemented with pthreads on a cluster of networked machines without any modifications to the target application. The DSM64 system features a centralized memory manager [1] built atop Hoard [2, 3]: a fast, scalable, and memory-efficient allocator for shared-memory multiprocessors. In my presentation, I present a SDSM system written in C++ for Linux operating systems. I discuss a straight-forward approa

Abstract:
The choices provided by an operating system to the application developer for managing memory came in two forms: no choice at all, with the operating system making all decisions about managing memory; or the choice to implement virtual memory management specific to the individual application. The second of these choices is, for all intents and purposes, the same as the first: no choice at all. For many application developers, the cost of implementing a customised virtual memory management system is just too high. The results is that, regardless of the level of flexibility available, the develop

Processing and optimizing ad-hoc and continual queries in an open environment with distributed, autonomous, and heterogeneous data servers (e.g., the Internet) pose several technical challenges.

When such assumptions no longer hold at runtime, how can I guarantee the optimized execution of the query?

Spatial diversity is an effective technique to combat the effects of severe fading in wireless environments.

It enables single-antenna terminals in a wireless relay network to share their antennas to form a virtual antenna array on the basis of their distributed locations. As such, the same divers

Enforcing security policies to distributed systems is difficult, in particular, when a system contains untrusted components.

One of the key language features is the predicates and functions that extract results of static program analysis, which are useful for defining security aspects that have to know about future behavior of a program.

碩士<br>國立交通大學<br>資訊工程研究所<br>83<br>Distributed computing systems (DCS) have become a major trend in computer system design today because of their high speed and high reliable performance advantages. Reliability is an important performance parameter in DCS design. Typically, redundant copies of software can be added to a system to increase system''s reliability. The distribution of program and data files can also affect the distributed program reliability (DPR) and distributed system reliability (DSR). The reliability- oriented file assignment problem is to find a file distribution such that prog

Abstract:
Distributed wireless sensor networks assess some parameter of interest connected with the earth by preparing the spatial-temporal information. Adaptive algorithms are applied to the distributed networks to endow the network with adaptation capabilities. The distributed network consists of many small sensors deployed randomly in a geographic area, which are adaptive and share their local information. Be that as it may all these disseminated techniques depend on the least mean square cost function which is delicate to the anomalies, for example, motivation clamour and impedance present in the wa

Abstract:
In cooperative networks, relays cooperate and form a distributed multi-antenna system to provide spatial diversity. In order to achieve high bandwidth efficiency, distributed space-time block codes (DSTBCs) are proposed and have been studied extensively. Among all DSTBCs, this thesis focuses on the codes which are single-symbol maximum likelihood (ML) decodable and can achieve the full diversity order. This thesis presents four works on single-symbol ML decodable DSTBCs. The first work proposes the row-monomial distributed orthogonal space-time block codes (DOSTBCs). We find an upper bound of

碩士<br>中華大學<br>機械與航太工程研究所<br>91<br>This research uses a general transfer matrix method (GTMM) and Timoshenko Principle for estimating the spatial unbalance parameters in rotor systems. Firstly we derive the motion equation of the flexible shaft, disks, and bearings. Through assembling the transfer matrices of the flexible shaft, disks, and bearings, we can obtain the global transfer matrix of the rotor system. The state variables of the transfer matrix include lateral deflections, deflection angles caused by shears and bending moments respectively, shears, bending moments, torque, and torsional

Abstract:
Analysis of networks is quite interesting, because they can be interpreted for several purposes. Various features require different metrics to measure and interpret them. Measuring the relative importance of each vertex in a network is one of the most fundamental building blocks in network analysis. Between’s Centrality (BC) is one such metric that plays a key role in many real world applications. BC is an important graph analytics application for large-scale graphs. However it is one of the most computationally intensive kernels to execute, and measuring centrality in billion-scale graphs is
