V.Selvan, S.http://dspace.wunu.edu.ua/handle/316497/321782018-12-11T12:38:11Z2009-01-01T00:00:00ZTitle: Parallel mining of large maximal bicliques using order preserving generators
Authors: Nataraj, R. V.; Selvan, S.
Abstract: In this paper, we propose a parallel algorithm for mining large maximal bicliques from graph datasets. We
propose POP-MBC (Parallel Order Preserving Maximal BiClique mining algorithm), a fast and memory efficient
parallel algorithm, which enumerates all the maximal bicliques independently and concurrently across several
processors without any synchronization between the processors. The POP-MBC algorithm is highly memory efficient
since it does not store the previously computed patterns in the main memory and requires only the dataset to be stored
in the memory. To enhance the load sharing among different nodes, POP-MBC uses a round robin strategy which
enables to achieve load balancing as high as 90%. We have also incorporated bit-vectors and numerous optimization
techniques exploiting the symmetric property of the graph dataset to reduce the memory consumption and overall
running time of the algorithm. Our comprehensive experimental analyses involving publicly available datasets show
that our algorithm distributes the load among the different processors equally and takes less memory, less running time
than other maximal biclique mining algorithms.2009-01-01T00:00:00ZThe bis-grid engine: an orchestration as a service infrastructureHöing, AndréScherp, GuidoGudenkauf, Stefanhttp://dspace.wunu.edu.ua/handle/316497/321772018-12-11T12:32:40Z2009-01-01T00:00:00ZTitle: The bis-grid engine: an orchestration as a service infrastructure
Authors: Höing, André; Scherp, Guido; Gudenkauf, Stefan
Abstract: The need for information system integration is typical for many companies including small and medium-sized
enterprises (SMEs). But especially for SMEs, the costs to run a full-fledged integration platform in-house are beyond
the available IT budget. This article describes the concept of Orchestration as a Service (OaaS), a specialization of the
Platform as a Service (PaaS) paradigm in the Cloud (computing) world. The goal of this paradigm is to provide a
workflow-based integration platform as a (Cloud) service focusing on so-called service orchestrations. We present the
BIS-Grid Engine as a core middleware for an OaaS infrastructure including a discussion about how our solution
addresses security requirements that are a key issue in Cloud technologies.2009-01-01T00:00:00ZSome aspects of increasing the processing power of the digital signal processorsPalagin, AlexanderSemotiuk, MiroslavVizor, YaroslavChichirin, Eugeniyhttp://dspace.wunu.edu.ua/handle/316497/321762018-12-11T12:26:57Z2009-01-01T00:00:00ZTitle: Some aspects of increasing the processing power of the digital signal processors
