  1. 1. Towards Low-Complexity Scalable Shared-Memory Architectures

    Författare :Håkan Zeffer; Erik Hagersten; John Carter; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; shared memory; distributed shared memory; hardware-software trade-off; software coherence; coherence profiling; remote access cache; chip multiprocessor; simultaneous multi threading; simulation; workload characterization; statistical cache model; Computer engineering; Datorteknik;

    Sammanfattning : Plentiful research has addressed low-complexity software-based shared-memory systems since the idea was first introduced more than two decades ago. However, software-coherent systems have not been very successful in the commercial marketplace. We believe there are two main reasons for this: lack of performance and/or lack of binary compatibility. LÄS MER

  3. 2. Iterative and Adaptive PDE Solvers for Shared Memory Architectures

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; partial differential equations; iterative methods; finite elements; conjugate gradients; adaptive mesh refinement; multigrid; cc-NUMA; distributed shared memory; OpenMP; page migration; TLB shoot-down; bandwidth minimization; reverse Cuthill-McKee; migrate-on-next-touch; affinity; temporal locality; chip multiprocessors; CMP; Beräkningsvetenskap; Scientific Computing;

    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

  4. 3. Exploiting Fine-grain Parallelism in Concurrent Constraint Languages

    Författare :Johan Montelius; RISE; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Implicit parallelism; Concurrent Constraint Programming; Cache performance; Logic programming; Abstract machine; Parallel execution; Scheduling; Multiprocessor; Shared memory;

    Sammanfattning : This dissertation presents the design, implementation, and evaluation of a system that exploits fine-grain implicit parallelism in concurrent constraint programming language. The system is able to outperform a C implementation of an algorithm with complex dependencies without any user annotations. LÄS MER
