    • Data placement in HPC architectures with heterogeneous off-chip memory 

      Pavlovic, Milan; Puzovic, Nikola; Ramírez Bellido, Alejandro (Institute of Electrical and Electronics Engineers (IEEE), 2013)
      Conference report
      Open Access
      The performance of HPC applications is often bounded by the underlying memory system's performance. The trend of increasing the number of cores on a chip imposes even higher memory bandwidth and capacity requirements. The ...

    • Energy efficiency vs. performance of the numerical solution of PDEs: an application study on a low-power ARM-based cluster 

      Göddeke, Dominik; Komatitsch, D.; Geveler, Markus; Ribbrock, D.; Rajovic, Nikola; Puzovic, Nikola; Ramírez Bellido, Alejandro (2013-03-05)
      Article
      Restricted access - publisher's policy
      Power consumption and energy efficiency are becoming critical aspects in the design and operation of large scale HPC facilities, and it is unanimously recognised that future exascale supercomputers will be strongly constrained ...

    • Experiences with mobile processors for energy efficient HPC 

      Rajovic, Nikola; Rico Carro, Alejandro; Vipond, James; Gelado Fernandez, Isaac; Puzovic, Nikola; Ramírez Bellido, Alejandro (2013)
      Conference report
      Restricted access - publisher's policy
      The performance of High Performance Computing (HPC) systems is already limited by their power consumption. The majority of top HPC systems today are built from commodity server components that were designed for maximizing ...

    • Parallelizing general histogram application for CUDA architectures 

      Milic, Ugljesa; Gelado Fernandez, Isaac; Puzovic, Nikola; Ramírez Bellido, Alejandro; Tomasevic, Milo (IEEE Computational Intelligence Society, 2013)
      Conference report
      Restricted access - publisher's policy
      Histogramming is a tool commonly used in data analysis. Although its serial version is simple to implement, providing an efficient and scalable way to parallelize it can be challenging. This especially holds in case of ...

    • Programmable and scalable reductions on clusters 

      Ciesko, Jan; Bueno Hedo, Javier; Puzovic, Nikola; Ramírez Bellido, Alejandro; Badia Sala, Rosa Maria; Labarta Mancho, Jesús José (Institute of Electrical and Electronics Engineers (IEEE), 2013)
      Conference report
      Restricted access - publisher's policy
      Reductions matter and they are here to stay. Wide adoption of parallel processing hardware in a broad range of computer applications has encouraged recent research efforts on their efficient parallelization. Furthermore, ...

    • Supercomputing with commodity CPUs: are mobile SoCs ready for HPC? 

      Rajovic, Nikola; Carpenter, Paul Matthew; Gelado Fernandez, Isaac; Puzovic, Nikola; Ramírez Bellido, Alejandro; Valero Cortés, Mateo (Association for Computing Machinery (ACM), 2013)
      Conference report
      Restricted access - publisher's policy
      In the late 1990s, powerful economic forces led to the adoption of commodity desktop processors in high-performance computing. This transformation has been so effective that the June 2013 TOP500 list is still dominated by ...
