Text en actes de congrés
Accés restringit per política de l'editorialPerformance evaluation tools enable analysts to shed light on how applications behave both from a general point of view and at concrete execution points, but cannot provide detailed information beyond the monitored regions ... -
Experiences on the characterization of parallel applications in embedded systems with Extrae/Paraver
Munera, Adrian; Royuela Alcázar, Sara; Llort Sánchez, Germán; Mercadal, Estanislao; Wartel, Franck; Quiñones, Eduardo (Association for Computing Machinery (ACM), 2020-08)
Comunicació de congrés
Accés obertCutting-edge functionalities in embedded systems require the use of parallel architectures to meet their performance requirements. This imposes the introduction of a new layer in the software stacks of embedded systems: ... -
Identifying code phases using piece-wise linear regressions
Servat, Harald; Llort Sánchez, Germán; González García, Juan; Giménez Lucas, Judit; Labarta Mancho, Jesús José (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 ... -
Intelligent instrumentation techniques to improve the traces information-volume ratio
Llort Sánchez, Germán (Universitat Politècnica de Catalunya, 2015-11-03)
Tesi
Accés obertWith ever more powerful machines being constantly deployed, it is crucial to manage the computational resources efficiently. This is important both from the point of view of the individual user, who expects fast results; ... -
