    A Family of Fault-Tolerant Efficient Indirect Topologies 
    Bermúdez Garzón, Diego Fernando; Gómez Requena, Crispín; Gómez Requena, María Engracia; López Rodríguez, Pedro Juan; Duato Marín, José Francisco (Institute of Electrical and Electronics Engineers (IEEE), 2016-04)
    On the one hand, performance and fault-tolerance of interconnection networks are key design issues for high performance computing (HPC) systems. On the other hand, cost should be also considered. Indirect topologies are ...

    Adaptive prefetch for multicores 
    Selfa Oliver, Vicent (Universitat Politècnica de València, 2016-01-08)
    [EN] Current multicore systems implement various hardware prefetchers since prefetching can significantly hide the huge main memory latencies. However, memory bandwidth is a scarce resource which becomes critical with ...

    Speeding-up the fault-tolerance analysis of interconnection networks 
    Bermúdez Garzón, Diego Fernando; Gómez Requena, Crispín; López Rodríguez, Pedro Juan; Gómez Requena, María Engracia (IEEE, 2015-07-20)
    Analyzing the fault-tolerance of interconnection networks implies checking the connectivity of each sourcedestination pair. The size of the exploration space of such operation skyrockets with the network size and with ...
