Regehr, John | Precise garbage collection for C | Magpie is a source-to-source transformation for C programs that enables precise garbage collection, where precise means that integers are not confused with pointers, and the liveness of a pointer is apparent at the source level. Precise GC is primarily useful for long-running programs and programs t... | | 2009-01-01 |

Gopalakrishnan, Ganesh | Precision on demand: an improvement in probabilistic hashing | In explicit state (enumerative) model checking, state vectors are often represented in a compressed form in order to reduce storage needs, typically employing fingerprints, bithashes, or state signatures. When using this kind of techniques, it could happen that the compressed image of a nonvisite... | Probabilistic hashing; Model checking | 2007 |

Gopalakrishnan, Ganesh | Predicate abstraction for Murphi | Predicate abstraction is a technique used to prove properties in a finite or infinite state system. It employs decision procedures to abstract a concrete state system into a finite state abstraction system, which will then be model checked and refined. In this paper, we present an approach for im... | Predicate abstraction; Murphi | 2006 |

Regehr, John | Predictable scheduling for digital audio | This paper presents results from applying the Rialto/ NT scheduler to some real Windows 2000 application scenarios. We report on two aspects of this work. First, we studied the reliability of an audio player application and the middleware and kernel components running beneath it in order to assess i... | | 2000-01-01 |

Regehr, John | The problems you're having may not be the problems you think you're having: results from a latency study of windows NT | This paper is intended to catalyze discussions on two intertwined systems topics. First, it presents early results from a latency study of Windows NT that identifies some specific causes of long thread scheduling latencies, many of which delay the dispatching of runnable threads for tens of millisec... | | 1999-01-01 |

Back, Godmar V. | Processes in KaffeOS: lsolation, resource management, and sharing in Java | Single-language runtime systems, in the form of Java virtual machines, are widely deployed platforms for executing untrusted mobile code. These runtimes provide some of the features that operating systems provide: inter-application memory protection and basic system services. They do not. however, p... | KaffeOS; Single-language; Java virtual machines; Mobile code; Runtimes | 2000 |

Schaelicke, Lambert | Profiling I/O interrupts in modern architectures | As applications grow increasingly communication-oriented, interrupt performance quickly becomes a crucial component of high performance I/O system design. At the same time, accurately measuring interrupt handler performance is difficult with the traditional simulation, instrumentation, or statistica... | | 1999 |

Orr, Douglas B. | Program specialization using the OMOS system | Abstraction and modularity provide many software engineering benefits. Hiding details of module internals can, however, prevent system implementors from being able to provide anything but a highly general implementation of a given module. We describe OMOS, a programmable linker/loader and system s... | OMOS system; Program specialization; Modularity; Linker/loader; Modules | 1995 |
