    Analyzing parallel programs has become increasingly difficult due to the immense amount of information collected on large systems. The use of clustering techniques has been proposed to analyze applications. However, while ...
  • Automatic evaluation of the computation structure of parallel applications 

    González García, Juan; Giménez Lucas, Judit; Labarta Mancho, Jesús José (Institute of Electrical and Electronics Engineers (IEEE), 2009)
    Conference report

    Many data mining techniques have been proposed for parallel applications performance analysis, the most inter- esting being clustering analysis. Most cases have been used to detect processors with similar behavior. In ...
  • Identifying code phases using piece-wise linear regressions 

    Servat Gelabert, Harald; Llort Sanchez, German Matías; González García, Juan; Giménez Lucas, Judit; Labarta Mancho, Jesús José (Institute of Electrical and Electronics Engineers (IEEE), 2014)
    Conference report

    Node-level performance is one of the factors that may limit applications from reaching the supercomputers' peak performance. Studying node-level performance and attributing it to the source code results into valuable insight ...
  • On the usefulness of object tracking techniques in performance analysis 

    Llort Sanchez, German Matías; Servat Gelabert, Harald; González García, Juan; Giménez Lucas, Judit; Labarta Mancho, Jesús José (Association for Computing Machinery (ACM), 2013)
    Conference report
    Restricted access - publisher's policy
    Understanding the behavior of a parallel application is crucial if we are to tune it to achieve its maximum performance. Yet the behavior the application exhibits may change over time and depend on the actual execution ...
  • On-line detection of large-scale parallel application's structure 

    Llort Sanchez, German Matías; González García, Juan; Servat Gelabert, Harald; Giménez Lucas, Judit; Labarta Mancho, Jesús José (Institute of Electrical and Electronics Engineers (IEEE), 2010)
    Conference report

    With larger and larger systems being constantly deployed, trace-based performance analysis of parallel applications has become a daunting task. Even if the amount of performance data gathered per single process is ...
  • Performance data extrapolation in parallel codes 

    González García, Juan; Giménez Lucas, Judit; Labarta Mancho, Jesús José (Institute of Electrical and Electronics Engineers (IEEE), 2010)
    Conference report

    Measuring the performance of parallel codes is a compromise between lots of factors. The most important one is which data has to be analyzed. Current supercomputers are able to run applications in large number of processors ...
  • Simulating whole supercomputer applications 

    González García, Juan; Casas, Marc; Giménez Lucas, Judit; Moreto Planas, Miquel; Ramírez Bellido, Alejandro; Labarta Mancho, Jesús José; Valero Cortés, Mateo (2011-06)
    Article
