Open AccessHybrid 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 ...
Servat, Harald; Peña, Antonio J.; Llort, German; Mercadal, Estanislao; Hoppe, Hans-Christian; Labarta Mancho, Jesús José (Institute of Electrical and Electronics Engineers (IEEE), 2017)
Open AccessMulti-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)
Open AccessCutting-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: ...
