  1. 1. An Object-Oriented Framework for PDE Solvers

    Författare :Krister Åhlander; Michael Thuné; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PDE; Navier-Stokes; object-oriented; overlapping grids; Numerical Analysis; Numerisk analys;

    Sammanfattning : The issue of how to develop reusable software in scientific computing is addressed. With object-oriented analysis and design, an extendable set of collaborating objects - a framework named COMPOSE - is suggested in the area of "PDE solvers", i.e., programs that numerically solve partial differential equations (PDEs).

  3. 2. Multithreaded PDE Solvers on Non-Uniform Memory Architectures

    Författare :Markus Nordén; Michael Thuné; Sverker Holmgren; Xing Cai; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PDE solver; high-performance; NUMA; UMA; OpenMP; MPI; data migration; data replication; thread scheduling; data affinity; Beräkningsvetenskap; Scientific Computing;

    Sammanfattning : A trend in parallel computer architecture 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). LÄS MER

    Sammanfattning : Scientific computing is used frequently in an increasing number of disciplines to accelerate scientific discovery. Many such computing problems involve the numerical solution of partial differential equations (PDE). LÄS MER

  7. 5. Parallel PDE Solvers on cc-NUMA Systems

    Författare :Markus Nordén; Michael Thuné; Sverker Holmgren; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Beräkningsvetenskap; Scientific Computing;

    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.
