    • Hypergraph-theoretic partitioning models for parallel web crawling 

      Türk, Ata; Cambazoğlu, B. Barla; Aykanat, Cevdet (Springer, London, 2012)
      Parallel web crawling is an important technique employed by large-scale search engines for content acquisition. A commonly used inter-processor coordination scheme in parallel crawling systems is the link exchange scheme, ...
    • Investigation of load balancing scalability in space plasma simulations 

      Türk, Ata; Demirci, Gündüz V.; Aykanat, Cevdet; Von Alfthan, S.; Honkonen I. (Springer, Berlin, Heidelberg, 2013)
      In this study we report the load-balancing performance issues that are observed during the petascaling of a space plasma simulation code developed at the Finnish Meteorological Institute (FMI). The code models the communication ...
    • Locality-aware and load-balanced static task scheduling for MapReduce 

      Selvitopu, Oğuz; Demirci, Gündüz Vehbi; Türk, Ata; Aykanat, Cevdet (Elsevier, 2018)
      Task scheduling for MapReduce jobs has been an active area of research with the objective of decreasing the amount of data transferred during the shuffle phase via exploiting data locality. In the literature, generally ...
    • Memory resident parallel inverted index construction 

      Küçükyılmaz, Tayfun; Türk, Ata; Aykanat, Cevdet (Springer, London, 2012)
      Advances in cloud computing, 64-bit architectures and huge RAMs enable performing many search related tasks in memory.We argue that term-based partitioned parallel inverted index construction is among such tasks, and provide ...
    • Page-to-processor assignment techniques for parallel crawlers 

      Türk, Ata (Bilkent University, 2004)
      In less than a decade, the World Wide Web has evolved from a research project to a cultural phenomena effective in almost every facet of our society. The increase in the popularity and usage of the Web enforced an increase ...
    • Selective replicated declustering for arbitrary queries 

      Oktay, K. Yasin; Türk, Ata; Aykanat, Cevdet (Springer, 2009-08)
      Data declustering is used to minimize query response times in data intensive applications. In this technique, query retrieval process is parallelized by distributing the data among several disks and it is useful in ...
    • Utilizing query logs for data replication and placement in big data applications 

      Türk, Ata (Bilkent University, 2012)
      The growth in the amount of data in todays computing problems and the level of parallelism dictated by the large-scale computing economics necessitates highlevel parallelism for many applications. This parallelism is ...
