  1. 1. Performance Characterization and Optimization of In-Memory Data Analytics on a Scale-up Server

    Författare :Ahsan Javed Awan; Eduard Ayguade; Mats Brorsson; Vladimir Vlassov; Lieven Eeckhout; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Workload Characterization; Big Data Analytics; Multicore Performance; Apache Spark; Near Data Processing; NUMA; Hyperthreading; Prefetchers; Coherently attached accelerators; Informations- och kommunikationsteknik; Information and Communication Technology;

    Sammanfattning : The sheer increase in the volume of data over the last decade has triggered research in cluster computing frameworks that enable web enterprises to extract big insights from big data. While Apache Spark defines the state of the art in big data analytics platforms for (i) exploiting data-flow and in-memory computing and (ii) for exhibiting superior scale-out performance on the commodity machines, little effort has been devoted to understanding the performance of in-memory data analytics with Spark on modern scale-up servers.

  3. 2. 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

  4. 3. 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
