    An efficient GPU implementation of fixed-complexity sphere decoders for MIMO wireless systems 
    Roger Varea, Sandra; Ramiro Sánchez, Carla; González Salvador, Alberto; Almenar Terré, Vicenç; Vidal Maciá, Antonio Manuel (IOS Press, 2012)
    The use of many-core processors such as general purpose Graphic Processing Units (GPUs) has recently become attractive for the efficient implementation of signal processing algorithms for communication systems. This is due ...

    Efficient Simulation of Spatio-temporal Dynamics in Ultrasonic Resonators 
    Alonso-Jordá, Pedro; Peinado Pinilla, Jesús; Pérez Arjona, Isabel; Sánchez Morcillo, Víctor José (Springer Verlag (Germany), 2011)
    The simulation in computers of the evolution of pressure and temperature inside a cavity when acoustic energy is injected results in a very stiff and high time consuming application. The split-step method used for the ...

    Phase-Aware Cache Partitioning to Target Both Turnaround Time and System Performance 
    Pons-Escat, Lucía; Sahuquillo Borrás, Julio; Selfa, Vicent; Petit Martí, Salvador Vicente; Pons Terol, Julio (Institute of Electrical and Electronics Engineers, 2020-11-01)
    [EN] The Last Level Cache (LLC) plays a key role in the system performance of current multi-cores by reducing the number of long latency main memory accesses. The inter-application interference at this shared resource, ...

    Thread Isolation to Improve Symbiotic Scheduling on SMT Multicore Processors 
    Feliu-Pérez, Josué; Sahuquillo Borrás, Julio; Petit Martí, Salvador Vicente; Eeckhout, Lieven (Institute of Electrical and Electronics Engineers, 2020-02-01)
    [EN] Resource sharing is a critical issue in simultaneous multithreading (SMT) processors as threads running simultaneously on an SMT core compete for shared resources. Symbiotic job scheduling, which co-schedules applications ...

    Tridimensional block multiword LDPC decoding on GPUs 
    Martínez Zaldívar, Francisco José; Vidal Maciá, Antonio Manuel; González Salvador, Alberto; Almenar Terré, Vicenç (Springer Verlag (Germany), 2011-12)
    [EN] In this paper, we describe a parallel algorithm for LDPC (Low Density Parity Check codes) decoding on a GPU (Graphics Processing Unit) using CUDA (Compute Unified Device Architecture). The strategy of the kernel grid ...
