  1. 1. Performance problem diagnosis in cloud infrastructures

    Detta är en avhandling från Umeå : Department of Computing Science, Umeå University

    Författare :Olumuyiwa Ibidunmoye; Umeå universitet.; [2016]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Systems Performance; Performance anomalies; Performance bottlenecks; Cloud infrastructures; Cloud Computing; Cloud Services; Cloud Computing Performance; Performance problems; Performance anomaly detection; Performance bottleneck identification; Performance Root-cause Analysis; Computer Systems; datorteknik; Computer Science; datalogi;

    Sammanfattning : Cloud datacenters comprise hundreds or thousands of disparate application services, each having stringent performance and availability requirements, sharing a finite set of heterogeneous hardware and software resources. The implication of such complex environment is that the occurrence of performance problems, such as slow application response and unplanned downtimes, has become a norm rather than exception resulting in decreased revenue, damaged reputation, and huge human-effort in diagnosis.

  2. 2. Enhancing Container Terminal Performance : A Multi Agent Systems Approach

    Detta är en avhandling från Karlskrona : Blekinge Institute of Technology

    Författare :Lawrence Henesey; Blekinge Tekniska Högskola.; [2004]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Container terminals; performance; Multi agents; Agent based technologies;

    Sammanfattning : This thesis seeks to understand and attempt to solve some of the problems that are facing many decision makers at container terminals. The growth of containerization, transporting goods in a container, has created many problems for ports, i.e. higher requirements on terminals and infrastructure. LÄS MER

  3. 3. Towards Scalable Performance Analysis of MPI Parallel Applications

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Xavier Aguilar; KTH.; [2015]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; parallel computing; performance monitoring; performance tools; event flow graphs; Datalogi; Computer Science;

    Sammanfattning :   A considerably fraction of science discovery is nowadays relying on computer simulations. High Performance Computing  (HPC) provides scientists with the means to simulate processes ranging from climate modeling to protein folding. LÄS MER

  4. 4. ADHD Symptoms Objective Performance and Subject Perspective

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Sara Scholtens; Uppsala universitet.; [2015]
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; ADHD; developmental psychology; academic performance; future orientation; cognitive performance; positive illusory bias; attachment representations; Psychology; Psykologi;

    Sammanfattning : ADHD research has mainly focused on objective performance measures. Performance, however, is only one aspect of functioning. Other aspects of how individuals function are their personal experiences and their evaluations of those experiences. LÄS MER

  5. 5. Software Design Conflicts Maintainability versus Performance and Availability

    Detta är en avhandling från Karlskrona : Blekinge Institute of Technology

    Författare :Daniel Häggander; Blekinge Tekniska Högskola.; [2001]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; object-oriented applications; design conflicts; performance; availability;

    Sammanfattning : A major goal in software engineering is to reduce the cost of maintaining software systems. Finding design methods which make software more easily maintainable has thus been one of the most prioritized challenges during the past decade. While mainstream software design has concentrated on maintainability, other software disciplines e.g. LÄS MER
