Landslide: Systematic Dynamic Race Detection in Kernel Space May 2012 89 pages
Authors:  Ben Blum; CARNEGIE-MELLON UNIV PITTSBURGH PA SCHOOL OF COMPUTER SCIENCE
The full text of this report is available for sale.Systematic exploration is an approach to finding race conditions by deterministically executing every possible interleaving of thread transitions and identifying which ones expose bugs. Current systematic exploration techniques are suitable for testing user-space programs, but are inadequate for testing kernels, where the testing framework's control over concurrency is more complicated. We present Landslide, a systematic exploration tool for finding races in kernels. Landslide targets Pebbles, the kernel specification that students ...


Debugging and Logging Services for Defence Service Oriented Architectures Feb 2012 31 pages
Authors:  Michael Pilling; DEFENCE SCIENCE AND TECHNOLOGY ORGANISATION EDINBURGH (AUSTRALIA) COMMAND CONTROL COMMUNICATIONS AND INTELLIGENCE DIV
The full text of this report is available for sale.While often thought of as a Dark Art, debugging is nevertheless a necessary part of fielding quality computing systems which can and should be done systematically. Service Oriented Architectures (SOAs) show great promise but also represent one of the most challenging environments in which to debug system services. In addition to all the issues of distributed and parallel debugging, SOAs introduce the complexity of significant parts of one's programs being ...


Concurrent Breakpoints 18 Dec 2011 16 pages
Authors:  Chang S Park; Koushik Sen; CALIFORNIA UNIV BERKELEY DEPT OF ELECTRICAL ENGINEERING AND COMPUTER SCIENCE
The full text of this report is available for sale.In program debugging, reproducibility of bugs is a key requirement. Unfortunately, bugs in concurrent programs are notoriously difficult to reproduce compared to their sequential counterparts. This is because bugs due to concurrency happen under very specific thread schedules and the likelihood of taking such corner-case schedules during regular testing is very low. We propose concurrent breakpoints, a light-weight and programmatic way to make a concurrency bug reproducible. We describe a ...

Continuous Improvement of Deployed Software Systems 28 Feb 2011 4 pages
Authors:  Ben Liblit; WISCONSIN UNIV-MADISON DEPT OF COMPUTER SCIENCES
The full text of this report is available for sale.We completed development of an adaptive binary instrumentor. We devised a taxonomy of adaptive instrumentation strategies, and a collection of several search heuristics within that taxonomy. Averaged across many applications, our best heuristic finds the top-ranked predictor while exploring only 40% of the program: a significant improvement over the 100% exploration required by prior approaches. Reducing instrumentation overhead has been a key goal of this research. The new instrumentor imposes ...


Statistical Debugging MAR 2008 109 pages
Authors:  Toriano A. Murphy; NAVAL POSTGRADUATE SCHOOL MONTEREY CA
The full text of this report is available for sale.Software debugging is a time consuming and important step in the development and evolution of software systems. Debugging is a practice that normally gets the least praise but normally requires the most attention and effort. The aim of debugging is to find and reduce the number of faults in a program, thereby making a program behave the way it is expected. Even with the advances that have been made with ...


Analyzing Memory Accesses in x86 Executables 2006 19 pages
Authors:  Gogul Balakrishnan; Thomas Reps; WISCONSIN UNIV-MADISON DEPT OF COMPUTER SCIENCES
The full text of this report is available for sale.This paper concerns static-analysis algorithms for analyzing x86 executables. The aim of the work is to recover intermediate representations that are similar to those that can be created for a program written in a high-level language. Our goal is to perform this task for programs such as plugins, mobile code, worms, and virus-infected code. For such programs, symbol-table and debugging information is either entirely absent, or cannot be relied upon ...

Automated Computation of Decomposable Synchronization Conditions FEB 1997 48 pages
Authors:  Gilberto Matos; James Purtilo; Elizabeth White; MARYLAND UNIV COLLEGE PARK INST FOR ADVANCED COMPUTER STUDIES
The full text of this report is available for sale.The most important aspect of concurrent and distributed computation is the interaction between system components. Integration of components into a system requires some synchronization that prevents the components from interacting in ways that may endanger the system users, its correctness or performance. The undesirable interactions are usually described using temporal logic, or safety and liveness assertions. Automated synthesis of synchronization conditions is a portable alternative to the manual design of ...

Development of a New Prediction Algorithm and a Simulator for the Predictive Read Cache (PRC) SEP 96 146 pages
Authors:  F. N. Altmisdort; NAVAL POSTGRADUATE SCHOOL MONTEREY CA
The full text of this report is available for sale.Efforts to bridge the cycle-time gap between high-end microprocessors and low-speed main memories have led to a hierarchical approach in memory subsystem design. The predictive read cache (PRC) has been developed as an alternative way to overcome the speed discrepancy without incurring the hardware cost of a second-level cache. Although the PRC can provide an improvement over a memory hierarchy using only a first-level cache, previous studies have shown that ...

Case-Based Planning: An Integrated Theory of Planning, Learning and Memory OCT 86
Authors:  Kristian J. Hammond; YALE UNIV NEW HAVEN CT DEPT OF COMPUTER SCIENCE
The full text of this report is not available and therefore is not for sale. This information is provided for reference purposes only.This dissertation presents a theory of case-based planning that integrates memory oriented learning with an active planner. Case-based planning requires a machine planner that makes use of its own past experience in developing new plans. A case-based planner relies on memory instead of a base of rules. Memories of past successes are accessed and modified to create new plans. Memories of past failures are used to warn the planner of ...


Debugging Parallel Programs with Instant Replay SEP 86
Authors:  Thomas J. LeBlanc; John M. Mellor-Crummey; ROCHESTER UNIV NY DEPT OF COMPUTER SCIENCE
The full text of this report is not available and therefore is not for sale. This information is provided for reference purposes only.The debugging cycle is the most common methodology for finding and correcting errors in sequential programs. Cyclic debugging is effective because sequential programs are usually deterministic. Debugging parallel programs is considerably more difficult because successive executions of the same program often do not produce the same results. In this paper we present a general solution for reproducing the execution behavior of parallel programs, termed Instant Replay. During program execution we ...

Efficient Modeling for Short Channel MOS Circuit Simulation AUG 1982
Authors:  Mark Griffin Johnson; MASSACHUSETTS INST OF TECH CAMBRIDGE LAB FOR COMPUTER SCIENCE
The full text of this report is not available and therefore is not for sale. This information is provided for reference purposes only.Existing circuit models for short-channel MOS transistors represent a compromise between computation speed and ease of use. Empirical models are very fast to evaluate, but their parameters must be fitted from experimental measurements. Theoretical models require longer computation time, but they may be used to predict the performance of new, unmeasured MOS technologies since their parameters are not curve-fitted from experimental data. This thesis combines the best features of both ...
