    • Analyzing the efficiency of hybrid codes 

      Giménez Lucas, Judit; Mercadal, Estanislao; Llort, German; Méndez, Sandra (Institute of Electrical and Electronics Engineers (IEEE), 2020)
      Conference report
      Open Access
      Hybrid parallelization may be the only path for most codes to use HPC systems on a very large scale. Even within a small scale, with an increasing number of cores per node, combining MPI with some shared memory thread-based ...
    • Automating the application data placement in hybrid memory systems 

      Servat, Harald; Peña, Antonio J.; Llort, German; Mercadal, Estanislao; Hoppe, Hans-Christian; Labarta Mancho, Jesús José (Institute of Electrical and Electronics Engineers (IEEE), 2017)
      Conference report
      Open Access
      Multi-tiered memory systems, such as those based on Intel® Xeon Phi™processors, are equipped with several memory tiers with different characteristics including, among others, capacity, access latency, bandwidth, energy ...
    • 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)
      Conference lecture
      Open Access
      Cutting-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: ...
    • The secrets of the accelerators unveiled: tracing heterogeneous executions through OMPT 

      Llort, German; Filgueras Izquierdo, Antonio; Jiménez-González, Daniel; Servat, Harald; Teruel, Xavier; Mercadal, Estanislao; Álvarez, Carlos; Giménez, Judit; Martorell Bofill, Xavier; Ayguadé Parra, Eduard; Labarta Mancho, Jesús José (Springer, 2016)
