    • An asymmetric distributed shared memory model for heterogeneous parallel systems 

      Gelado Fernandez, Isaac; Cabezas, Javier; Navarro, Nacho; Stone, John E.; Patel, Sanjay; Hwu, Wen-mei W. (2010)
      Text en actes de congrés
      Accés obert
      Heterogeneous computing combines general purpose CPUs with accelerators to efficiently execute both sequential control-intensive and data-parallel phases of applications. Existing programming models for heterogeneous ...

    • Comparison based sorting for systems with multiple GPUs 

      Tanasic, Ivan; Vilanova, Lluís; Jorda, Marc; Cabezas, Javier; Gelado Fernandez, Isaac; Navarro, Nacho; Hwu, Wen-mei W. (Association for Computing Machinery (ACM), 2013)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      As a basic building block of many applications, sorting algorithms that efficiently run on modern machines are key for the performance of these applications. With the recent shift to using GPUs for general purpose compuing, ...

    • CUsched: multiprogrammed workload scheduling on GPU architectures 

      Tanasic, Ivan; Gelado Fernandez, Isaac; Cabezas, Javier; Navarro, Nacho; Ramírez Bellido, Alejandro; Valero Cortés, Mateo (2013)
      Report de recerca
      Accés obert
      Graphic Processing Units (GPUs) are currently widely used in High Performance Computing (HPC) applications to speed-up the execution of massively-parallel codes. GPUs are well-suited for such HPC environments because ...

    • Enabling preemptive multiprogramming on GPUs 

      Tanasic, Ivan; Gelado Fernandez, Isaac; Cabezas, Javier; Ramírez Bellido, Alejandro; Navarro, Nacho; Valero Cortés, Mateo (Institute of Electrical and Electronics Engineers (IEEE), 2014)
      Text en actes de congrés
      Accés obert
      GPUs are being increasingly adopted as compute accelerators in many domains, spanning environments from mobile systems to cloud computing. These systems are usually running multiple applications, from one or several users. ...

    • High-performance reverse time migration on GPU 

      Cabezas, Javier; Ayala Polo, Mauricio; Gelado Fernandez, Isaac; Morancho Llena, Enrique; Navarro, Nacho; Cela Espín, José M. (2009-11)
      Text en actes de congrés
      Accés obert
      Partial Differential Equations (PDE) are the heart of most simulations in many scientific fields, from Fluid Mechanics to Astrophysics. One the most popular mathematical schemes to solve a PDE is Finite Difference (FD). In ...

    • Optimization of atmospheric transport models on HPC platforms 

      de la Cruz, Raúl; Folch, Arnau; Farré, Pau; Cabezas, Javier; Navarro, Nacho; Cela, José M. (Elsevier, 2016-12)
      Article
      Accés obert
      The performance and scalability of atmospheric transport models on high performance computing environments is often far from optimal for multiple reasons including, for example, sequential input and output, synchronous ...
