  1. 1. Real-Time GPU Algorithms: Parallel Primitives and Rendering of Participating Media

    Författare :Markus Billeter; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; grids; indirect illumination; shafts of light; multiple scattering; stream compaction; single scattering; parallel primitives; GPGPU;

    Sammanfattning : Modern graphics processing units, GPUs, present an immense resource of computational power, that however remains challenging to fully harness. This thesis explores four algorithms and methods that attempt to take full advantage of the resources provided by a GPU. LÄS MER

  3. 2. Embedded Languages for Data-Parallel Programming

    Författare :Joel Bo Svensson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Graphics Processing Units; Data-parallelism; Functional Programming; Embedded languages;

    Sammanfattning : Computers today are becoming more and more parallel. General purpose processors (CPUs) have multiple processing cores and Single Instruction Multiple Data (SIMD) units for data-parallelism. Graphics processors (GPUs) bring massive parallelism at the cost of being harder to program than CPUs. LÄS MER

  4. 3. Electrothermal Simulation in a Concurrent Waveform Relaxation Based Circuit Simulator

    Författare :Magnus Wiklund; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Circuit synthesis; Bond graphs; Nullor; Circuit theory; Analog simulation; Circuit simulation; Multiprocessor computer; CONCISE; Parallel computation; Waveform relaxation; Thermal models; Transistor models; Electro-thermal simulation; Electro-thermal modeling; Translinear circuits; Electronics; Elektronik; Electrical engineering; Elektroteknik;

    Sammanfattning : The main purpose of this work is to study methods to simulate electro-thermal effects in integrated circuits using CONCISE a waveform relaxation based circuit simulator. WR is a method that is suitable to run on a multi-computer with state of the art computing power. Especially CMOS VLSI circuits have been simulated successfully with WR. LÄS MER

  5. 4. Compiler Generation for Data-Parallel Programming Languages from Two-Level Semantics Specifications

    Författare :Johan Ringström; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This thesis is an empirical study of compiler generation for data-parallel languages from denotational-semantics-based formal specifications. We investigate whether compiler generation from such specifications is practical, not only with respect to generation of practical compilers, but also with respect to compilation of programs into efficient code and execution of the compiled programs on massively parallel SIMD (Single Instruction Multiple Data) architectures.

  7. 5. Scalable Scientific Stream Query Processing

    Författare :Milena Ivanova; Tore Risch; Elke A. Rundensteiner; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; data stream management systems; parallel stream processing; scientific stream query processing; user-defined stream partitioning; Computer science; Datalogi; Data- och systemvetenskap; Computer Systems Sciences;

    Sammanfattning : Scientific applications require processing of high-volume on-line streams of numerical data from instruments and simulations. In order to extract information and detect interesting patterns in these streams scientists need to perform on-line analyses including advanced and often expensive numerical computations. LÄS MER
