      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 Sánchez, Germán; Servat, Harald; González García, Juan; Giménez Lucas, Judit; Labarta Mancho, Jesús José (Association for Computing Machinery (ACM), 2013)

      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 Sánchez, Germán; González García, Juan; Servat, Harald; Giménez Lucas, Judit; Labarta Mancho, Jesús José (Institute of Electrical and Electronics Engineers (IEEE), 2010)

      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)

      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; Moretó Planas, Miquel; Ramírez Bellido, Alejandro; Labarta Mancho, Jesús José; Valero Cortés, Mateo (2011-06)
