Book SynopsisThe 1980's saw the advent of widespread (and potentially damaging) computer virus infection of both personal computer and mainframe systems. The computer security field has been comparatively slow to react to this emerging situation. It is only over the last two years that a significant body of knowledge on the operation, likely evolution and prevention of computer viruses has developed. A Pathology of Computer Viruses gives a detailed overview of the history of the computer virus and an in-depth technical review of the principles of computer virus and worm operation under DOS, Mac, UNIX and DEC operating systems. David Ferbrache considers the possible extension of the threat to the mainframe systems environment and suggests how the threat can be effectively combatted using an antiviral management plan. The author addresses the latest developments in "stealth" virus operations, specifically the trend for virus authors to adopt extensive camouflage and concealment techniques, which allow viruses to evade both existing anti-viral software and to avoid detection by direct observation of machine behaviour. A Pathology of Computer Viruses addresses a distinct need - that of the computer specialist and professional who needs a source reference work detailing all aspects of the computer virus threat.Table

Book SynopsisThis volume contains the papers selected after a very careful refereeing process for presentation during the Workshop on Job Scheduling Stategies for Parallel Processing, held in Santa Barbara, California, as a prelude to the IPPS '95 conference in April 1995.The 19 full papers presented demonstrate that parallel job scheduling takes on a crucial role as multi-user parallel supercomputers become more widespread. All aspects of job scheduling for parallel systems are covered, from the perspectives of academic research, industrial design of parallel systems, as well as user needs. Of particular interest, also for nonexpert readers, is the introductory paper "Parallel Job Scheduling: Issues and Approaches" by the volume editors.Table of ContentsParallel job scheduling: Issues and approaches.- Scheduling on the Tera MTA.- A scalable multi-discipline, multiple-processor scheduling framework for IRIX.- Scheduling to reduce memory coherence overhead on coarse-grain multiprocessors.- Time Space Sharing Scheduling and architectural support.- Demand-based coscheduling of parallel jobs on multiprogrammed multiprocessors.- Multiprocessor scheduling for high-variability service time distributions.- The interaction between memory allocation and adaptive partitioning in message-passing multicomputers.- Analysis of non-work-conserving processor partitioning policies.- Loop-Level Process Control: An effective processor allocation policy for multiprogrammed shared-memory multiprocessors.- A microeconomic scheduler for parallel computers.- On the benefits and limitations of dynamic partitioning in parallel computer systems.- Intelligent fuzzy control to augment scheduling capabilities of network queuing systems.- Parallel processing on dynamic resources with CARMI.- Job scheduling under the Portable Batch System.- The ANL/IBM SP scheduling system.- Requirements of the Cornell Theory Center for resource management and process scheduling.- Job management requirements for nas parallel systems and clusters.- Job characteristics of a production parallel scientific workload on the NASA Ames iPSC/860.

Book SynopsisIn modern computing a program is usually distributed among several processes. The fundamental challenge when developing reliable and secure distributed programs is to support the cooperation of processes required to execute a common task, even when some of these processes fail. Failures may range from crashes to adversarial attacks by malicious processes.Cachin, Guerraoui, and Rodrigues present an introductory description of fundamental distributed programming abstractions together with algorithms to implement them in distributed systems, where processes are subject to crashes and malicious attacks. The authors follow an incremental approach by first introducing basic abstractions in simple distributed environments, before moving to more sophisticated abstractions and more challenging environments. Each core chapter is devoted to one topic, covering reliable broadcast, shared memory, consensus, and extensions of consensus. For every topic, many exercises and their solutions enhance the understanding This book represents the second edition of "Introduction to Reliable Distributed Programming". Its scope has been extended to include security against malicious actions by non-cooperating processes. This important domain has become widely known under the name "Byzantine fault-tolerance".
