Kirby, Robert Michael | Verifying volume rendering using discretization error analysis | We propose an approach for verification of volume rendering correctness based on an analysis of the volume rendering integral, the basis of most DVR algorithms. With respect to the most common discretization of this continuous model (Riemann summation), we make assumptions about the impact of parame... | | 2014-01-01 |

Carter, Tony M. | Cascade: a hardware alternative to bignums | The Cascade hardware architecture for high/variable precision arithmetic is described. It uses a radix-16 redundant signed-digit number representation and directly supports single or multiple precision addition, subtraction, multiplication, division, extraction of the square root and computation of ... | Cascade hardware; Bignums; Precision arithmetic | 1989 |

George, Lal | A scheduling strategy for shared memory multiprocessors | An efficient scheduling strategy for shared memory multiprocessors is described. The rapid dissemination of tasks to available procesors and ready queues is crucial to the performance of any parallel system. Such overheads determine the attainable speedup and performance of the system. Poor techniq... | Shared memory multiprocessors | 1990 |

Balasubramonian, Rajeev | Dynamically tunable memory hierarchy | The widespread use of repeaters in long wires creates the possibility of dynamically sizing regular on-chip structures. We present a tunable cache and translation lookaside buffer (TLB) hierarchy that leverages repeater insertion to dynamically trade off size for speed and power consumption on a per... | Microarchitecture; High performance microprocessors; Reconfigurable architectures; Energy and performance of on-chip caches; Translation lookaside buffer (TLB); Tunable cache | 2003-10 |

Hansen, Charles D. | Multidimensional transfer functions for interactive volume rendering | Abstract-Most direct volume renderings produced today employ one-dimensional transfer functions which assign color and opacity to the volume based solely on the single scalar quantity which comprises the data set. Though they have not received widespread attention, multidimensional transfer function... | | 2002-07 |

Pascucci, Valerio | Topology verification for isosurface extraction | The broad goals of verifiable visualization rely on correct algorithmic implementations. We extend a framework for verification of isosurfacing implementations to check topological properties. Specifically, we use stratified Morse theory and digital topology to design algorithms which verify topolog... | | 2012-01-01 |

Orr, Douglas B. | Dynamic program monitoring and transformation using the OMOS object server | In traditional monolithic operating systems the constraints of working within the kernel have limited the sophistication of the schemes used to manage executable program images. By implementing an executable image loader as a persistent user-space program, we can extend system program loading capabi... | Program monitoring; Object/Meta-Object Server; OMOS | 1992 |

Gopalakrishnan, Ganesh | Efficient symbolic simulation based verification using the parametric form of boolean expressions (rev.) | We present several new techniques to make symbolic simulation based verification efficient. These techniques hinge on the use of the parametric form of a boolean expression (e.g. the parametric form for the boolean expression XQ V -<xi is the equivalent expression 3a b . (XQ = a V 6) A (xi = b), whe... | Symbolic simulation; Verification | 1991 |

Regehr, John | Evolving real-time systems using hierarchical scheduling and concurrency analysis | We have developed a new way to look at real-time and embedded software: as a collection of execution environments created by a hierarchy of schedulers. Common schedulers include those that run interrupts, bottom-half handlers, threads, and events. We have created algorithms for deriving response tim... | | 2003-01-01 |

Baker, Jason; Hsieh, Wilson C. | Maya: multiple-dispatch syntax extension in Java | We have designed and implemented Maya, a version of Java that allows programmers to extend and reinterpret its syntax. Maya generalizes macro systems by treating grammar productions as generic functions, and semantic actions on productions as multimethods on the corresponding generic functions. P... | Maya; Syntax extension | 2001-12-11 |

Hansen, Charles D. | Model for volume lighting and modeling | Abstract-Direct volume rendering is a commonly used technique in visualization applications. Many of these applications require sophisticated shading models to capture subtle lighting effects and characteristics of volumetric data and materials. For many volumes, homogeneous regions pose problems f... | | 2003-04 |

Balasubramonian, Rajeev | NDC: Analyzing the impact of 3D-stacked memory+logic devices on MapReduce workloads | While Processing-in-Memory has been investigated for decades, it has not been embraced commercially. A number of emerging technologies have renewed interest in this topic. In particular, the emergence of 3D stacking and the imminent release of Micron's Hybrid Memory Cube device have made it more pra... | | 2014-01-01 |

Johnson, Christopher R.; Parker, Steven G.; Hansen, Charles D. | Interactive simulation and visualization | Most of us perform data analysis and visualization only after everything else is finished, which often means that we don't discover errors invalidating the results of our simulation until postprocessing. A better approach would be to improve the integration of simulation and visualization into the... | Computational steering; Interactive simulation; Isosurfaces | 1999 |

Henderson, Thomas C. | Parallel path consistency | Filtering algorithms are well accepted as a means of speeding up the solution of the consistent labeling problem (CLP). Despite the fact that path consistency does a better job of filtering than arc consistency, AC is still the preferred technique because it has a much lower time complexity. We ar... | Filtering algorithms; Parallel paths; Consistency; Consistent labeling problem; CLP | 1991 |
