  2. 6. Decentralized resource brokering for heterogeneous grid environments

    Author : Johan Tordsson; Erik Elmroth; Bo Kågström; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Grid computing; Resource brokering; interoperability; advance reservations; coallocation; Web services; Computer science; Datavetenskap;

    Abstract : The emergence of Grid computing infrastructures enables researchers to share resources and collaborate in more efficient ways than before, despite belonging to different organizations and being distanced geographically. While the Grid computing paradigm offers new opportunities, it also gives rise to new difficulties. READ MORE

  4. 7. Efficient Partitioning of Dynamic Structured Grid Hierarchies

    Author : Johan Steensland; Michael Thuné; Jarmo Rantakokko; Charles Norton; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; scientific computing; partitioning; structured grids; adaptive mesh refinement; dynamic load balancing; Beräkningsvetenskap; Scientific Computing;

    Abstract : This thesis aims at decreasing execution time for large-scale structured adaptive mesh refinement (SAMR) applications executing on general parallel computers. The key contributions are (1) A conceptual dynamically adaptive meta-partitioner able to select and configure an appropriate partitioning technique, based on application and computer state, and (2) A characterization of new and existing domain-based partitioners, enabling a mapping from application and computer state onto appropriate partitioners, and (3) Sketched scalable solutions, expressed in terms of natural regions and expert algorithms, for the problem to efficiently partition large-scale SAMR applications with deep grid hierarchies executing on general parallel computers, and (4) A software partitioning tool Nature+Fable, implementing the greater parts of these sketched scalable solutions and engineered as part of the meta-partitioner.

  5. 8. Searches for Higgs bosons with hadronically decaying τ-leptons : Using Grid and Cloud computing techniques

    Author : Henrik Öhman; Arnaud Ferrari; Paula Eerola; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; LHC; ATLAS; Higgs; Charged Higgs; Tau lepton; 2HDM; MSSM; Fysik med inriktning mot elementarpartikelfysik; Physics with specialization in Elementary Particle Physics;

    Abstract : This thesis describes a measurement of the Standard Model Higgs boson coupling to fermions in decays to two τ-leptons, a search for charged Higgs bosons in decays to a τ-lepton and a neutrino, as well as the reconstruction, identification and triggering of hadronically decaying τ-leptons. The data considered are collected by the ATLAS experiment at the Large Hadron Collider. READ MORE

  6. 9. Multi-Agent Based Simulations in the Grid Environment

    Author : Dawit Mengistu; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Grid computing; Multi-agent Based Simulation; Performance Modeling; Performance Prediction;

    Abstract : The computational Grid has become an important infrastructure as an execution environment for scientific applications that require large amount of computing resources. Applications which would otherwise be unmanageable or take a prohibitively longer execution time under previous computing paradigms can now be executed efficiently on the Grid within a reasonable time.

  7. 10. An e-Science Approach to Genetic Analysis of Quantitative Traits

    Author : Mahen Jayawardena; Sverker Holmgren; Erwin Laure; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; QTL Analysis; Grid Computing; Global Optimization; e-Science; Beräkningsvetenskap; Scientific Computing;

    Abstract : Many important traits in plants, animals and humans are quantitative, and most such traits are generally believed to be affected by multiple genetic loci. Standard computational tools for mapping of quantitative traits (i.e. READ MORE
