    • Energy optimizing methodologies on heterogeneous data centers 

      Nishtala, Rajiv; Carpenter, Paul; Petrucci, Vinicius; Martorell Bofill, Xavier (Barcelona Supercomputing Center, 2017-05-04)
      Conference report
      Open Access
      In 2013, U.S. data centers accounted for 2.2% of the country’s total electricity consumption, a figure that is projected to increase rapidly over the next decade. Many important work-loads are interactive, and they demand ...
    • Flying real-time network for disaster assistance 

      Santos, Rodrigo; Orozco, Javier; Mossé, Daniel; Petrucci, Vinicius; Ochoa, Sergio; Meseguer Pallarès, Roc (2017)
      Conference report

      Landslides and large floods are serious natural disasters that every year cause multiple deaths and loss in property around the world. When these events occur in areas like the “favelas” or mountain regions in coastal ...
    • Flying real-time network to coordinate disaster relief activities in urban areas 

      Micheletto, Matías; Petrucci, Vinicius; Santos, Rodrigo; Orozco, Javier; Mossé, Daniel; Ochoa, Sergio; Meseguer Pallarès, Roc (Multidisciplinary Digital Publishing Institute (MDPI), 2018-05-22)
      Article
      Open Access
      While there have been important advances within wireless communication technology, the provision of communication support during disaster relief activities remains an open issue. The literature in disaster research reports ...

    • Intelligent colocation of HPC workloads 

      Vieira Zacarias, Felippe; Petrucci, Vinicius; Nishtala, Rajiv; Carpenter, Paul; Mossé, Daniel (Elsevier, 2021-05)
      Article
      Restricted access - publisher's policy
      Many server applications suffer from a bottleneck in the shared caches, instruction execution units, I/O or memory bandwidth, even though the remaining resources may be underutilized. It is hard for developers and runtime ...
    • REPP-H: runtime estimation of power and performance on heterogeneous data centers 

      Nishtala, Rajiv; Martorell Bofill, Xavier; Petrucci, Vinicius; Mossé, Daniel (2016)
      Conference report
      Open Access
      Modern data centers increasingly demand improved performance with minimal power consumption. Managing the power and performance requirements of the applications is challenging because these data centers, incidentally or ...
