  1. 1. 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.

  5. 4. Methods for Creating and Exploiting Data Locality

    Författare :Dan Wallin; Erik Hagersten; Sverker Holmgren; David Wood; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; data locality; temporal locality; spatial locality; prefetching; cache; cache behavior; cache coherence; snooping protocols; partial differential equation; shared-memory multiprocessor; chip multiprocessor; simulation; Computer engineering; Datorteknik;

    Sammanfattning : The gap between processor speed and memory latency has led to the use of caches in the memory systems of modern computers. Programs must use the caches efficiently and exploit data locality for maximum performance. LÄS MER

  7. 5. Exploiting data locality in adaptive architectures

    Författare :Dan Wallin; Erik Hagersten; Sverker Holmgren; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer Systems; Datorteknik;

    Sammanfattning : The speed of processors increases much faster than the memory access time. This makes memory accesses expensive. To meet this problem, cache hierarchies are introduced to serve the processor with data. However, the effectiveness of caches depends on the amount of locality in the application's memory access pattern. LÄS MER
