    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (257 KB) | HTML iconHTML

    Management of directories with millions of files, accessed by thousands of clients at the same time, is a problem recently identified in HPC environments. This paper introduces an OSD+-based technique to deal with those directories. We use directory objects in OSD+ devices for dynamically distributing a huge directory among several servers. Directory objects work independently, achieving good perf... View full abstract»

  • Genetic Algorithms Hierarchical Execution Control under a Global Application State Monitoring Infrastructure

    Publication Year: 2013, Page(s):16 - 23
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (575 KB) | HTML iconHTML

    We present a new approach to the design of parallel genetic algorithms executed in multicore processor systems. To design the algorithms, a programming environment is used with parallel program global control flow functions and asynchronous process/thread internal behaviour control. Global application states monitoring is provided by generalized synchronization processes called synchronizers which... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (672 KB) | HTML iconHTML

    Decision Support System (DSS) workloads are known to be one of the most time-consuming database workloads that process large data sets. Traditionally, DSS queries have been accelerated using large-scale multiprocessors. In this work we exploit the benefits of using future many-core architectures, more specifically on-chip clustered many-core architectures. To achieve this goal we propose different...

  • Identifying Critical Code Sections in Dataflow Programming Models

    Publication Year: 2013, Page(s):29 - 37
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (575 KB) | HTML iconHTML

    The years of practice in optimizing applications point that the major issue is focus - identifying the critical code section whose optimization would yield the highest overall speedup. While this issue is mainly solved for sequential applications, it remains a serious hurdle in the world of parallel computing. Furthermore, the newest dataflow parallel programming models expose very irregular paral... View full abstract»

  • Performance Traps in OpenCL for CPUs

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (335 KB) | HTML iconHTML

    With its design concept of cross-platform portability, OpenCL can be used not only on GPUs (for which it is quite popular), but also on CPUs. Whether porting GPU programs to CPUs, or simply writing new code for CPUs, using OpenCL brings up the performance issue, usually raised in one of two forms: "OpenCL is not performance portable!" or "Why using OpenCL for CPUs after all?!". We argue that both ... View full abstract»

  • A RISC Building Block Set for Structured Parallel Programming

    Publication Year: 2013, Page(s):46 - 50
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (246 KB) | HTML iconHTML

    We propose a set of building blocks (RISC-pb2l) suitable to build high-level structured parallel programming frameworks. The set is designed following a RISC approach. RISC-pb2l is architecture independent but the implementation of the different blocks may be specialized to make the best usage of the target architecture peculiarities. A number of optimizations may be designed transforming basic bu... View full abstract»

  • A Distributed Eigensolver for Loosely Coupled Networks

    Cited by:  Papers (4)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (315 KB) | HTML iconHTML

    We introduce a new distributed eigensolver (dOI) for square matrices based on orthogonal iteration. In contrast to standard parallel eigensolvers, our approach performs only nearest neighbor communication and provides much more flexibility with respect to the properties of the hardware infrastructure on which the computation is performed. This is achieved by utilizing distributed summation methods... View full abstract»

  • Efficient Cooperative Discovery of Service Compositions in Unstructured P2P Networks

    In this paper, we propose an efficient technique for improving the performance of automatic and cooperative compositions in P2P unstructured networks during service discovery. Since the adoption of flooding to exchange queries and partial solutions among the peers of unstructured networks generates a huge amount of messages, the technique exploits a probabilistic forwarding algorithm that uses dif...

    Multimedia consumption over the Internet is emerging as one of the largest sink of network resources, making scalable and reliable streaming increasingly challenging. To address this challenge, we propose ReStream, an adaptive replication algorithm that relies on replication to achieve reliable and scalable streaming in resource-constrained environments. Our algorithm dynamically adapts replica pl... View full abstract»

    Kernel density estimation is nowadays very popular tool for nonparametric probabilistic density estimation. One of its most important disadvantages is computational complexity of computations needed, especially for large data sets. One way for accelerating these computations is to use the parallel computing with multi-core platforms. In this paper we parallelize two kernel estimation methods such ... View full abstract»

    In this paper, the method of data intensive computing is studied for large amounts of data in computed tomography (CT). An automatic workflow is built up to connect the tomography beamline of ANKA with the large scale data facility (LSDF), able to enhance the data storage and analysis efficiency. In this workflow, this paper focuses on the parallel computing of 3D computed tomography reconstructio... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (655 KB) | HTML iconHTML

    Many hybrid Flash Translation Layer (FTL) schemes have been proposed to leverage the erase-before-write and limited lifetime constraints of flash memories. Those schemes try to approach page mapping performance and flexibility while seeking block mapping memory usage. Furthermore, flash-specific cache systems were designed (1) to maximize lifetime by absorbing some erase operations, and (2) to rev... View full abstract»

    In this paper, we investigate the problem of results merging in distributed information retrieval when overlapping databases are used. We focus on two issues: score normalization and weights assignment for each of the component results. Empirical study with the TREC data has the following three findings: 1. The cubic regression model and logistic regression model are better than the commonly used ... View full abstract»

    Focused crawlers are programs designed to download web pages which are relevant to specific topics. Using information gathered at running time, focused crawlers explore the web following promissory hyperlinks and fetching only pages which appear to be relevant. These crawlers are receiving increasing attention because they favor the construction of vertical search engines, allowing users to focus ... View full abstract»
