Book excerpt: The major research results from the Scalable Input/Output Initiative, exploring software and algorithmic solutions to the I/O imbalance. As we enter the "decade of data," the disparity between the vast amount of data storage capacity (measurable in terabytes and petabytes) and the bandwidth available for accessing it has created an input/output bottleneck that is proving to be a major constraint on the effective use of scientific data for research. Scalable Input/Output is a summary of the major research results of the Scalable I/O Initiative, launched by Paul Messina, then Director of the Center for Advanced Computing Research at the California Institute of Technology, to explore software and algorithmic solutions to the I/O imbalance. The contributors explore techniques for I/O optimization, including: I/O characterization to understand application and system I/O patterns; system checkpointing strategies; collective I/O and parallel database support for scientific applications; parallel I/O libraries and strategies for file striping, prefetching, and write behind; compilation strategies for out-of-core data access; scheduling and shared virtual memory alternatives; network support for low-latency data transfer; and parallel I/O application programming interfaces.

This book was released on 2004-04-19 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fundamental aspect of the Internet architecture that distinguishes it from other network technologies (such as X. 25 and ATM) is that it is c- nectionless (vs. connection-oriented) and stateless (vs. stateful). The heated debateofwhetherconnection-orientedorconnectionlessarchitectureisbetter has lasted for several decades. Proponents of the connectionless architecture point out the great robustness and scalability properties of the architecture, as demonstratedby the Internet. Onewell-knownarticulationofthis philo- phy is the "End-to-End Arguments". Opponents argue, rightfully, that there is no known solution that can provide quantitative performance assurances or guaranteed QoS in a connectionless network. It has been widely rec- nized that QoS is a must-have feature as the Internet technology evolves to the next stage. However, all existing solutions that provide guaranteed QoS require routers to maintain per?ow (another name for connection used by the Internet community) state, which is the fundamental element of a connection-oriented architecture. The apparent con?icting goals of having a stateless network and supporting QoS have presented a great dilemma for Internet architects. As an example, Dave Clark, one of the most respected Internet architects and the author of the famous "End-to-End Arguments" paper, wasalsoakeydesigneroftheInternetIntegratedServicesArchitecture that requires routers to maintain per?ow state. Dr. Ion Stoica's dissertation addresses this most pressing and di?cult problem facing the Internet community today: how to enhance the Internet to support rich functionalities (such as QoS and tra?c management) while still maintaining the scalability and robustness properties embodied in the original Internet architecture.

Download or read book Scalable Dynamic Analysis of Binary Code written by Ulf Kargén and published by Linköping University Electronic Press. This book was released on 2019-08-22 with total page 73 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, binary code analysis, i.e., applying program analysis directly at the machine code level, has become an increasingly important topic of study. This is driven to a large extent by the information security community, where security auditing of closed-source software and analysis of malware are important applications. Since most of the high-level semantics of the original source code are lost upon compilation to executable code, static analysis is intractable for, e.g., fine-grained information flow analysis of binary code. Dynamic analysis, however, does not suffer in the same way from reduced accuracy in the absence of high-level semantics, and is therefore also more readily applicable to binary code. Since fine-grained dynamic analysis often requires recording detailed information about every instruction execution, scalability can become a significant challenge. In this thesis, we address the scalability challenges of two powerful dynamic analysis methods whose widespread use has, so far, been impeded by their lack of scalability: dynamic slicing and instruction trace alignment. Dynamic slicing provides fine-grained information about dependencies between individual instructions, and can be used both as a powerful debugging aid and as a foundation for other dynamic analysis techniques. Instruction trace alignment provides a means for comparing executions of two similar programs and has important applications in, e.g., malware analysis, security auditing, and plagiarism detection. We also apply our work on scalable dynamic analysis in two novel approaches to improve fuzzing — a popular random testing technique that is widely used in industry to discover security vulnerabilities. To use dynamic slicing, detailed information about a program execution must first be recorded. Since the amount of information is often too large to fit in main memory, existing dynamic slicing methods apply various time-versus-space trade-offs to reduce memory requirements. However, these trade-offs result in very high time overheads, limiting the usefulness of dynamic slicing in practice. In this thesis, we show that the speed of dynamic slicing can be greatly improved by carefully designing data structures and algorithms to exploit temporal locality of programs. This allows avoidance of the expensive trade-offs used in earlier methods by accessing recorded runtime information directly from secondary storage without significant random-access overhead. In addition to being a standalone contribution, scalable dynamic slicing also forms integral parts of our contributions to fuzzing. Our first contribution uses dynamic slicing and binary code mutation to automatically turn an existing executable into a test generator. In our experiments, this new approach to fuzzing achieved about an order of magnitude better code coverage than traditional mutational fuzzing and found several bugs in popular Linux software. The second work on fuzzing presented in this thesis uses dynamic slicing to accelerate the state-of-the-art fuzzer AFL by focusing the fuzzing effort on previously unexplored parts of the input space. For the second dynamic analysis technique whose scalability we sought to improve — instruction trace alignment — we employed techniques used in speech recognition and information retrieval to design what is, to the best of our knowledge, the first general approach to aligning realistically long program traces. We show in our experiments that this method is capable of producing meaningful alignments even in the presence of significant syntactic differences stemming from, for example, the use of different compilers or optimization levels.

Download or read book Achieving Accuracy written by Marshall William McMurran and published by Xlibris Corporation. This book was released on 2008-12-11 with total page 398 pages. Available in PDF, EPUB and Kindle. Book excerpt: “A Legacy of Computers and Missiles “is an intensively researched, photo-enhanced discussion of digital computing and missile development in the Twentieth Century, organized in two sections. (No matter what anyone has been told, virtually all of the digital machines ever designed are binary deep down inside. Number representations may have varied, but the binary logic discussed here prevails.) After a bit of early history, The Computing Section begins in earnest with Turing’s Bombe used to decrypt Enigma traffic, then investigates one-by-one digital systems from early room-sized serial machines through the beginning of the modern parallel era, ending with disgustingly parallel post 2000 Super-computers. Unlike most computing histories, Achieving Accuracy deals in detail with military computing systems generally omitted for lack of definitive information. (Computer design and computer-controlled missile guidance/ submarine navigation occupied some thirty years of the Author’s professional career. ) Achieving Accuracy‘s missile descriptions and discussions begin for weapon systems existing well before WW2 and cover virtually all US smart bombs, cruise and ballistic missiles of that century. Missile guidance systems have ranged from the V-1’s dead reckoning through simple, but jammable radio-controlled, to exceedingly complex self-contained inertial guidance systems discussed at length. The reader may be surprised to learn that a “smart-bomb” flew in 1917, with several different models used in anger in WW2. The Minuteman III leg of the present Triad is described in detail along with a somewhat bizarre set of proposed basing plans for the Peacekeeper Missile that were precursors of the recently proposed “Subway” basing plan for MMIII. Missile legacy includes a sub-section, necessarily less complete, describing Soviet/Russian missilery through 2000, noting that the early Soviet ballistic missile development was based almost entirely on the German V-2.

Download or read book Novel Motion Anchoring Strategies for Wavelet based Highly Scalable Video Compression written by Dominic Rüfenacht and published by Springer. This book was released on 2018-04-03 with total page 182 pages. Available in PDF, EPUB and Kindle. Book excerpt: A key element of any modern video codec is the efficient exploitation of temporal redundancy via motion-compensated prediction. In this book, a novel paradigm of representing and employing motion information in a video compression system is described that has several advantages over existing approaches. Traditionally, motion is estimated, modelled, and coded as a vector field at the target frame it predicts. While this “prediction-centric” approach is convenient, the fact that the motion is “attached” to a specific target frame implies that it cannot easily be re-purposed to predict or synthesize other frames, which severely hampers temporal scalability. In light of this, the present book explores the possibility of anchoring motion at reference frames instead. Key to the success of the proposed “reference-based” anchoring schemes is high quality motion inference, which is enabled by the use of a more “physical” motion representation than the traditionally employed “block” motion fields. The resulting compression system can support computationally efficient, high-quality temporal motion inference, which requires half as many coded motion fields as conventional codecs. Furthermore, “features” beyond compressibility — including high scalability, accessibility, and “intrinsic” framerate upsampling — can be seamlessly supported. These features are becoming ever more relevant as the way video is consumed continues shifting from the traditional broadcast scenario to interactive browsing of video content over heterogeneous networks. This book is of interest to researchers and professionals working in multimedia signal processing, in particular those who are interested in next-generation video compression. Two comprehensive background chapters on scalable video compression and temporal frame interpolation make the book accessible for students and newcomers to the field.
