    Sammanfattning : The current trend in parallel computers is that systems with a large shared memory are becoming more and more popular. A shared memory system can be either a uniform memory architecture (UMA) or a cache coherent non-uniform memory architecture (cc-NUMA).In the present thesis, the performance of parallel PDE solvers on cc-NUMA computers is studied.

    Författare :Christopher Johansson; KTH; []
    Nyckelord :Attractor Neural Networks; Cerebral Cortex; Minicolumns; Hypercolumns; Potts Neural Networks; BCPNN; and Parallel Computers;

    Sammanfattning : In this thesis we model the mammalian cerebral cortex withattractor neural networks and study the parallelimplementations of these models. First, we review the size, structure, and scaling laws ofthe cerebral cortex of five mammals; mouse, rat, cat, macaque,and human. LÄS MER

  5. 19. Performance characterization and evaluation of parallel PDE solvers

    Författare :Henrik Johansson; Jarmo Rantakokko; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Beräkningsvetenskap; Scientific Computing;

    Sammanfattning : Computer simulations that solve partial differential equations (PDEs) are common in many fields of science and engineering. To decrease the execution time of the simulations, the PDEs can be solved on parallel computers. For efficient parallel implementations, the characteristics of both the hardware and the PDE solver must be taken into account. LÄS MER

  7. 20. A scalable data structure for a parallel data server

    Författare :Jonas S. Karlsson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Modern and future applications, such as in the telecommunication industry and real-time systems, store and manage very large amounts of information. This information needs to be accessed and searched with high performance, and it must have high availability. Databases are traditionally used for managing high volumes of data. LÄS MER
