This tutorial will present an overview of program anomaly detection, which analyzes normal program behaviors and discovers aberrant executions caused by attacks, misconfigurations, program bugs, and unusual usage patterns. It was first introduced as an ...

A simple bug in a program can influence a large part of the program execution by spreading throughout the state at runtime. This is known as program infection. The seriousness of bugs is usually measured by studying their external effects. However, ...

If we develop a new dynamic analysis tool, how should we expose its functionalities? Through an interactive user interface, a DSL, a specific API, or in some other way? In this paper, we discuss how to use an already existing language familiar to most ...

BLAST is a framework for deep analysis of Java program executions. It captures the entire information flow of an execution. A BLAST trace represents the space-time history of a program run: It combines space (heap, static, and stack memory locations) ...

Instruction traces play an important role in analyzing and understanding the behavior of target applications; however, existing tracing tools are built on specific platforms coupled with excessive reliance on compilers and operating systems. In this ...

Online progress in search and optimization is often hindered by neutrality in the fitness landscape, when many genotypes map to the same fitness value. We propose a method for imposing a gradient on the fitness function of a metaheuristic (in this case, ...

This paper introduces a new unobtrusive and cost-effective method for the capture and compression of program execution traces in real-time, which is based on a double move-to-front transformation. We explore its effectiveness and describe a cost-...

This paper presents a novel approach to make the on-chip instruction cache of a SoC to function simultaneously as a regular instruction cache and a real time program trace compressor. This goal is accomplished by exploiting the dictionary feature of the ...

The RISC revolution has spurred the development of processors with increasing degrees of instruction level parallelism (ILP). In order to realize the full potential of these processors, multiple instructions must continuously be issued and executed in a ...

The nature by which branches and data dependencies generate delays that degrade pipeline performance is investigated in this paper. We show that for the general execution trace, few specific delays can be considered in isolation; rather, the magnitude ...

An algorithm is given for synthesizing a computer program from a trace of its behavior. Since the algorithm involves a search, the length of time required to do the synthesis of nontrivial programs can be quite large. Techniques are given for ...
