  1. 1. Understanding Multicore Performance : Efficient Memory System Modeling and Simulation

    Författare :Andreas Sandberg; Erik Hagersten; David Black-Schaffer; David A. Wood; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer Architecture; Simulation; Modeling; Sampling; Caches; Memory Systems; gem5; Parallel Simulation; Virtualization; Sampling; Multicore; Datavetenskap; Computer Science;

    Sammanfattning : To increase performance, modern processors employ complex techniques such as out-of-order pipelines and deep cache hierarchies. While the increasing complexity has paid off in performance, it has become harder to accurately predict the effects of hardware/software optimizations in such systems. LÄS MER

  3. 2. Hiding and Reducing Memory Latency : Energy-Efficient Pipeline and Memory System Techniques

    Författare :Andreas Sembrant; David Black-Schaffer; Erik Hagersten; David A. Wood; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Computer Science; Datavetenskap;

    Sammanfattning : Memory accesses in modern processors are both far slower and vastly more energy-expensive than the actual computations. To improve performance, processors spend a significant amount of energy and resources trying to hide and reduce the memory latency. LÄS MER

  4. 3. Poplar wood formation : genotypical influences on structure and chemistry

    Författare :David Sandquist; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Genotypical effects on wood formation in aspen (Populus tremula x tremuloides) have been studied at morphological, ultrastructural and micro-distributional levels. To characterize transgenically in­duced modifications, light-, fluorescence-, UV-, scanning- and transmission electron microscopy have been applied complement­ed by immunolabeling, histochemistry, multivariate statistics and image analysis.

  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. Function of MAP20 and MYB103 in cellulose and lignin formation of xylem secondary cell walls

    Författare :David Öhman; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Lignocellulose from trees and other crops will have tremendous impact on the next generation of sustainable biofuels and biomaterials. To take advantage of modern breeding tools, it is therefore important to understand the genetic and molecular regulation underlying secondary cell wall formation. LÄS MER
