This book presents the first integrated, single-source reference on market-oriented grid and utility computing. Divided into four main parts—and with contributions from a panel of experts in the field—it systematically and carefully explores:
Foundations—presents the fundamental concepts of market-oriented computing and the issues and challenges in allocating resources in a decentralized computing environment.
Delivering Utility Computing
We live in an era of change; not only is change happening all the time, but the rate of change is accelerating and customers’ requirements and the environments that provide them are not the only factors affected. While we were writing this book there were a number of large IT industry mergers, not least when the company we both work for, VERITAS Software, merged with Symantec Corporation in July 2005.

Single processor supercomputers have achieved great speeds and have been pushing
hardware technology to the physical limit of chip manufacturing. But soon this trend
will come to an end, because there are physical and architectural bounds, which limit
the computational power that can be achieved with a single processor system. In this
book, we study advanced computer architectures that utilize parallelism via multiple

With the current interpretation, covering all information technology research and engineering work related to information processing.
Consolidation of applications in cloud computing environments presents a significant opportunity for energy optimization. As a first step toward enabling energy efficient consolidation, we study the inter-relationships between energy consumption, resource utilization, and performance of consolidated workloads. The study reveals the energy performance trade-offs for consolidation and shows that optimal operating points exist. We model the consolidation problem as a modified bin packing problem and illustrate it with an example.
Trong số nhiều thuật sĩ (wizard) và tiện ích được tích hợp trong Microsoft Windows XP, System Configuration Utility hay MSCONFIG là một tiện ích khá hữu dụng được giới thiệu trong dòng hệ điều hành Windows 9.x.
Nếu bạn đã từng sử dụng Windows XP thì chắc hẳn các bạn sẽ biết được rằng tính năng Backup Utility không hề được Microsoft hỗ trợ trong phiên bản XP Home Edition mà chỉ được giới thiệu trong Professional Edition.
For over four years, the largest computing systems in the world have been based on ‘distributed computing’, the assembly of large numbers of PCs over the Internet. These ‘Grid’ systems sustain multiple teraﬂops continuously by aggregating hundreds of thousands to millions of machines, and demonstrate the utility of such resources for solving a surprisingly wide range of large-scale computational problems in data mining, molecular interaction, ﬁnancial modeling, and so on.
Computational Grids  have emerged as a distributed computing infrastructure for providing pervasive, ubiquitous access to a diverse set of resources ranging from highperformance computers (HPC), tertiary storage systems, large-scale visualization systems, expensive and unique instruments including telescopes and accelerators. One of the primary motivations for building Grids is to enable large-scale scientiﬁc research projects to better utilize distributed, heterogeneous resources to solve a particular problem or set of problems....
Event related potentials (ERP) corresponding to stimuli in electroencephalography (EEG) can be used to detect the intent of a person for brain computer interfaces (BCI). This paradigm is widely used to build letter-byletter text input systems using BCI. Nevertheless using a BCI-typewriter depending only on EEG responses will not be sufﬁciently accurate for single-trial operation in general, and existing systems utilize many-trial schemes to achieve accuracy at the cost of speed.
Carriers and enterprises are looking for inexpensive ways to utilize their infrastructures to take
advantage of the cost effectiveness of Ethernet transport and services. One area currently under
consideration is how to fully utilize fiber build-outs to continue to offer revenue-generating
services such as voice, and to add new packet-based services at the same time. The LoopStar711
is a fixed configuration, multi-service access platform offering cost-effective and easy-to-manage
Ethernet and TDM-based services that allow for the full utilization of fiber networks....
This book is about Tcl, the scripting language developed by John Ousterhout. Tcl
stands for tool command language and was originally designed as a simple scripting
language interpreter that could be embedded inside applications written in the
C language. With the addition of the Tk graphical toolkit and a host of other language
extensions supporting such features as graphics, relational databases, and
object-oriented programming, Tcl has become a popular programming language
for developing applications in its own right.
This handbook is designed to help you find ways to protect
your Windows XP/Vista/7 PC and ensure your data is safe. I get
countless emails from site visitors who ask about the best antivirus software, firewall program, backup utilities etc. and there
are often questions like this in the forums.
I set up PCs for companies, friends, and family; the advice I
give in this manual is what I use when building any PC. My tips
are tried and tested and have left hundreds of people satisfied
with the way their computer works. I hope you too can follow
This chapter defines system software and discusses two types of system software: operating systems and utility programs. You learn what an operating system is and explore user interfaces, operating systems features, and operating system functions.
We examine the utility of speech and lexical features for predicting student emotions in computerhuman spoken tutoring dialogues. We ﬁrst annotate student turns for negative, neutral, positive and mixed emotions. We then extract acoustic-prosodic features from the speech signal, and lexical items from the transcribed or recognized speech. We compare the results of machine learning experiments using these features alone or in combination to predict various categorizations of the annotated student emotions. ...
In recent years,a great deal of evidence has been collected which gives substantially increased insight into the nature of human speech perception. It is the author's belief that such data can be effectively used to infer much of the structure of a practical speech recognition system. This paper details a new view of the role of structural constraints within the several structural domains (e.g. articulation, phonetics, phonology, syntax, semantics) that must be utilized to infer the desired percept. ...
A considerable body of accumulated knowledge about the design of languages for communicating information to computers has been derived from the subfields of programming language design and semantics. It has been the goal of the P A r R group at SRI to utilize a relevant portion of this knowledge in implementing tools to facilitate communication of linguistic information to computers. The PATR-II formalism is our current computer language for encoding linguistic information.
We present a general treatment of the comparative that is based on more basic linguistic elements so that the underlying system can be effectively utilized: in the syntactic analysis phase, the comparative is treated the same as similar structures; in the syntactic regularization phase, the comparative is transformed into a standard form so that subsequent proceasing is basically unaffected by it. The scope of quantifiers under the comparative is also integrated into the system in a general way. ...
