      Cyber-Physical Systems (CPSs) are widely necessary for many applications that require interactions with the humans and the physical environment. A CPS integrates a set of hardware-software components to distribute, execute ...
    • Implementing OmpSs support for regions of data in architectures with multiple address spaces 

      Bueno Hedo, Javier; Martorell Bofill, Xavier; Badia Sala, Rosa Maria; Ayguadé Parra, Eduard; Labarta Mancho, Jesús José (ACM, 2013)
      Conference report
      Restricted access - publisher's policy
      The need for features for managing complex data accesses in modern programming models has increased due to the emerging hardware architectures. HPC hardware has moved towards clusters of accelerators and/or multicores, ...
    • Measuring TCP bandwidth on top of a Gigabit and Myrinet network 

      Costa Prats, Juan José; Bueno Hedo, Javier; Martorell Bofill, Xavier; Cortés, Toni (2009)
      External research report
      Open Access
      In this article we measure the bandwidth achieved by the TCP protocol on top of a Gigabit and Myrinet network. We have created a synthetic benchmark, consisting on a server and a client that both produce and consume data, ...
    • Productive cluster programming with OmpSs 

      Bueno Hedo, Javier; Martinell Andreu, Luis; Duran González, Alejandro; Farreras Esclusa, Montserrat; Martorell Bofill, Xavier; Badia Sala, Rosa Maria; Ayguadé Parra, Eduard; Labarta Mancho, Jesús José (Springer, 2011)
      Conference report

      Clusters of SMPs are ubiquitous. They have been traditionally programmed by using MPI. But, the productivity of MPI programmers is low because of the complexity of expressing parallelism and communication, and the difficulty ...
    • Productive programming of GPU clusters with OmpSs 

      Bueno Hedo, Javier; Planas, Judit; Duran González, Alejandro; Badia Sala, Rosa Maria; Martorell Bofill, Xavier; Ayguadé Parra, Eduard; Labarta Mancho, Jesús José (2012)
      Conference lecture
      Restricted access - publisher's policy
      Clusters of GPUs are emerging as a new computational scenario. Programming them requires the use of hybrid models that increase the complexity of the applications, reducing the productivity of programmers. We present ...
    • 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, ...
    • Run-time support for multi-level disjoint memory address spaces 

      Bueno Hedo, Javier (Universitat Politècnica de Catalunya, 2015-11-05)
      Doctoral thesis
      Open Access
      High Performance Computing (HPC) systems have become widely used tools in many industry areas and research fields. Research to produce more powerful and efficient systems has grown in par with their popularity. As a ...
