  1. 6. 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

  3. 7. Effective cooperative scheduling of task-parallel applications on multiprogrammed parallel architectures

    Författare :Georgios Varisteas; Mats Brorsson; Avi Mendelson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multicore; parallel; scheduler; workload; runtime; task; adaptive; resource management; load balancing; work-stealing; Computer Science; Datalogi;

    Sammanfattning : Emerging architecture designs include tens of processing cores on a single chip die; it is believed that the number of cores will reach the hundreds in not so many years from now. However, most common parallel workloads cannot fully utilize such systems. LÄS MER

  4. 8. Models and Methods for Development of DSP Applications on Manycore Processors

    Författare :Jerker Bengtsson; Bertil Svensson; Shuvra S. Bhattacharyya; Högskolan i Halmstad; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; parallel processing; manycore processors; high-performance digital signal processing; dataflow; concurrent models of computation; parallel code mapping; parallel machine model; dynamic performance analysis; Computer engineering; Datorteknik;

    Sammanfattning : Advanced digital signal processing systems require specialized high-performance embedded computer architectures. The term high-performance translates to large amounts of data and computations per time unit. The term embedded further implies requirements on physical size and power efficiency. LÄS MER

  5. 9. Change Point Detection with Applications to Wireless Sensor Networks

    Författare :Markus Eriksson; Tomas Olofsson; Idris Eckley; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Change Point Detection; Signal Processing; Dynamic Programming; Electrical Engineering with specialization in Signal Processing; Elektroteknik med inriktning mot signalbehandling;

    Sammanfattning : In this thesis work we develop a new algorithm for detecting joint changes in statistical behavior of multiple, simultaneously recorded, signals. Such signal analysis is commonly known as multivariate change point (CP) detection (CPD) and is of interest in many scientific and engineering applications. LÄS MER

  7. 10. On adaptive sorting in sequential and parallel models

    Författare :Ola Petersson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Sorting is probably the most well-studied problem in computer science. In many applications the elements to be sorted are not randomly distributed, but are already nearly ordered. Most existing algorithms do not take advantage of this fact. LÄS MER
