Application of clustering analysis and sequence analysis on the performance analysis of parallel applications
(Universitat Politècnica de Catalunya, 2013-06-07)
Tesi
Accés obertHigh Performance Computing and Supercomputing is the high end area of the computing science that studies and develops the most powerful computers available. Current supercomputers are extremely complex so are the applications ... -
Automatic detection of parallel applications computation phases
(Institute of Electrical and Electronics Engineers (IEEE), 2014)
Text en actes de congrés
Accés restringit per política de l'editorialAnalyzing 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
(Institute of Electrical and Electronics Engineers (IEEE), 2009)
Text en actes de congrés
Accés restringit per política de l'editorialMany 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
(Institute of Electrical and Electronics Engineers (IEEE), 2014)
Text en actes de congrés
Accés restringit per política de l'editorialNode-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
(Association for Computing Machinery (ACM), 2013)
Text en actes de congrés
Accés restringit per política de l'editorialUnderstanding 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
(Institute of Electrical and Electronics Engineers (IEEE), 2010)
Text en actes de congrés
Accés restringit per política de l'editorialWith 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
(Institute of Electrical and Electronics Engineers (IEEE), 2010)
Text en actes de congrés
Accés restringit per política de l'editorialMeasuring 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
(2011-06)
Article
Accés restringit per política de l'editorialDetailed simulations of large scale message-passing interface parallel applications are extremely time consuming and resource intensive. A new methodology that combines signal processing and data mining techniques plus a ...
