  1. 21. High Performance Hybrid Memory Systems with 3D-stacked DRAM

    Författare :Evangelos Vasilakis; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hybrid memory systems; DRAM caches; Data migration; 3D-stacked DRAM;

    Sammanfattning : The bandwidth of traditional DRAM is pin limited and so does not scale well with the increasing demand of data intensive workloads limiting performance. 3D-stacked DRAM can alleviate this problem providing substantially higher bandwidth to a processor chip. LÄS MER

  3. 22. Data Prefetching Techniques Targeting Single and a Network of Processing Nodes

    Författare :Magnus Karlsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : This thesis considers two approaches to the design of high-performance computers. In a single processing node with one processor, performance is degraded when requested data is not found in the cache, because it has to be retrieved from slower memory. LÄS MER

  4. 23. 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

  5. 24. Design Considerations of Value-aware Caches

    Författare :Angelos Arelakis; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Memory; Data Compression; Statistical-based Compression; Value Locality; Cache; Huffman Coding;

    Sammanfattning : On-chip cache memories are instrumental in tackling several performance and energy issues facing contemporary and future microprocessor chip architectures. First, they are key to bridge the growing speed-gap between memory and processors. LÄS MER

  7. 25. Adaptive Resource Management Techniques for High Performance Multi-Core Architectures

    Författare :Nadja Holtryd; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cache Partitioning; Bandwidth Partitioning; Resource Management; Performance Isolation; Multi-Core Architectures; Prefetch Throttling;

    Sammanfattning : Reducing the average memory access time is crucial for improving the performance of applications executing on multi-core architectures. With workload consolidation this becomes increasingly challenging due to shared resource contention. Previous works has proposed techniques for partitioning of shared resources (e.g. LÄS MER
