deadlock

BOOK EXCERPT:

When Chicago Black Hawks hockey legend Boom Boom Warshawski slips off a wharf and drowns in Lake Michigan, his private-eye cousin questions the accidental death report and rumors of suicide. Armed with a bottle of Black Label and a Smith & Weson, V.I. follows a trail of violence and corruption to the center of the Windy City's powerful shipping industry. Dodging elaborate attempts on her life with characteristic grit and humor, the one-of-a-kind detective wends her way through a maze of grain elevators and thousand-ton freighters, ruthless businessmen and gorgeous ballerinas, to ferret out Boom Boom's killers before they phase her out of the picture—permanently. Praise for Deadlock “V.I. Warshawski is one of the best . . . smart, tough, sexy.”—Daily News (New York) “Sara Paretsky makes excellent use of local backgrounds in a carefully plotted tale of murder and great misdeeds in the world of Great Lakes cargo shipping.”—Chicago Tribune “Hard-boiled detective fiction . . . a swift-paced and engrossing read.”—The Philadelphia Inquirer “Slithers with suspense!”—Chicago Sun-Times

BOOK EXCERPT:

This exhilarating FBI thriller by #1 New York Times bestselling author Catherine Coulter finds Savich and Sherlock confronting two baffling mysteries. A young wife is forced to confront a decades-old deadly secret when a medium connects her to her dead grandfather. A vicious psychopath wants ultimate revenge against Savich, but first, she wants to destroy what he loves most—his family. A series of three red boxes are delivered personally to Savich at the Hoover Building, each one containing puzzle pieces of a town only FBI agent Pippa Cinelli recognizes. Savich sends in Cinelli to investigate undercover but someone knows who she is. Savich and Sherlock are up to their eyebrows in danger, but can they figure out the red box puzzle and the young wife’s secret before it’s too late?

BOOK EXCERPT:

A deadlock occurs when there is a cyclic dependency between two or more threads, or processes, for some set of resources within operating system environment. A set of processes is deadlocked if each process is waiting for an event that only another process in the set can cause. My thesis aims at creating a tool, which can be used by an application developer for detecting the occurrence of a deadlock. It also helps the developer in analyzing the cause of deadlock, since the project provides him with information, such as the deadlocked processes and the resources causing it. The developer can also view the log file, which is generated by this tool to study the sequence of events, such as locking or unlocking of the resources. The outline of the project is as follows: A wrapper function dd_semop has been developed around the system call semop. An application program has to include a header file "libdeadlock.h" in order to use this wrapper functionality. A daemon process has also been developed dl_mgmt, which carries out the major functionality for deadlock detection and recovery. The wrapper function communicates with the daemon process, which runs in the background and actually verifies whether a lock can be granted or not and communicates back the possibility of a deadlock. Once the tool provides the output and depending on the users feedback to it, the tool provides a mechanism to continue execution without deadlock. Thus, this research project provides a comprehensible tool to study and manage deadlocks in a Linux flavor known as Fedora. Deadlock is thus a potential problem. Timely detection of deadlock and its cause are essential for resolving the error and maintaining forward progress.

BOOK EXCERPT:

Deadlock problems in flexible manufacturing systems (FMS) have received more and more attention in the last two decades. Petri nets are one of the more promising mathematical tools for tackling deadlocks in various resource allocation systems. In a system modeled with Petri nets, siphons are tied to the occurrence of deadlock states as a structural object. The book systematically introduces the novel theory of siphons, traps, and elementary siphons of Petri nets as well as the deadlock control strategies for FMS developed from it. Deadlock prevention methods are examined comparatively. The many FMS examples presented to demonstrate the concepts and results of this book range from the simple to the complex. Importantly, to inspire and motive the reader’s interest in further research, a number of interesting and open problems in this area are proposed at the end of each chapter.

BOOK EXCERPT:

The problem of deadlocks in distributed systems can be handled by prevention, avoidance and detection strategies. All methods require modeling the system by Resource Allocation graphs or Transaction-Wait-For graphs. The current methods can fail to detect deadlocks in some system scenarios and also do not provide numerical values for system deadlock probability. Analysis of complex distributed systems with varying number of processes and resources requires a computerized solution. We developed a General Transaction program, based on a technique defined as Resource Allocation Arrays, which provides a framework for representing process resource interactions in the system. The State Identifier program uses this framework to develop system state space diagrams. The State Identifier program also identifies the deadlock states in the system. Models developed in OPNET simulate the system state space and provide numerical values for probability of being in any state of the system, and in effect the probability of reaching a system deadlock. Data shows that the simulation models are 99.86% accurate. The developed computerized approach substantially reduces the numerical analysis and computational time for analyzing such complex system scenarios.

BOOK EXCERPT:

Complex computer-integrated systems offer enormous benefits across a wide array of applications, including automated production, transportation, concurrent software, and computer operating systems, computer networks, distributed database systems, and many other automated systems. Yet, as these systems become more complex, automated, distributed, and computing-intensive, the opportunity for deadlock issues rises exponentially. Deadlock modeling, detection, avoidance, and recovery are critical to improving system performance. Deadlock Resolution in Computer-Integrated Systems is the first text to summarize and comprehensively treat this issue in a systematic manner. Consisting of contributions from prominent researchers in the field, this book addresses deadlock-free models and scheduling, detection and recovery methods, the formulation of dynamic control policies, and comparison and industrial benchmark studies that evaluate various approaches. The editors lay the foundation for exploring deadlock issues with a typical example of an automated manufacturing process, illustrating three primary modeling methods (digraphs, Petri nets, and automata) and comparing their respective advantages and disadvantages. Providing all of the important models and resolution approaches, this book is the complete guide for electrical and control engineers and manufacturing, intelligent, and network systems designers to prevent and manage deadlock issues in their systems.

BOOK EXCERPT:

Hutch is a newspaper columnist, single dad . . . and last defense against a lunatic's high-tech killing machine. Special Forces veteran-turned-billionaire Brendan Page has some dirty not-so-little secrets. He's built an empire on supplying futuristic weapons and highly trained soldiers to the world's most powerful armies. But he's saved his most destructive weapons for himself. John Hutchinson, a Denver newspaper columnist and avid bow-hunter, has figured out the truth about Brendan Page and is determined to bring him down. But he's up against a warmonger linked to assasinations, kidnappings, and terrorist activities. Hutch quickly uncovers a plan that seems unfathomable in its recklessness and loss of life. Yet he's just one man up against impossible odds--with no Plan B. Thankfully, it's just the kind of environment Hutch thrives best in . . . if he can survive the next three days. Deadlock will grab you from the riveting first page to its white-knuckle climax. "With a blistering pace and irresistable characters, Deadlock is the best of high-octane suspense." - Gayle Lynds, New York Times best-selling author of The Last Spymaster
