    • MUSA: a multi-level simulation approach for next-generation HPC machines 

      Grass, Thomas; Allande, César; Armejach, Adrià; Rico, Alejandro; Ayguadé Parra, Eduard; Labarta Mancho, Jesús José; Valero Cortés, Mateo; Casas, Marc; Moretó Planas, Miquel (Institute of Electrical and Electronics Engineers (IEEE), 2016)
      Text en actes de congrés
      Accés obert
      The complexity of High Performance Computing (HPC) systems is increasing in the number of components and their heterogeneity. Interactions between software and hardware involve many different aspects which are typically ...

    • Sampled simulation of task-based programs 

      Grass, Thomas; Carlson, Trevor E.; Rico Carro, Alejandro; Ceballos, Germán; Ayguadé Parra, Eduard; Casas, Marc; Moretó Planas, Miquel (Institute of Electrical and Electronics Engineers (IEEE), 2019-02-01)
      Article
      Accés obert
      Sampled simulation is a mature technique for reducing simulation time of single-threaded programs. Nevertheless, current sampling techniques do not take advantage of other execution models, like task-based execution, to ...

    • Simulation methodologies for future large-scale parallel systems 

      Grass, Thomas (Universitat Politècnica de Catalunya, 2017-10-09)
      Tesi
      Accés obert
      Since the early 2000s, computer systems have seen a transition from single-core to multi-core systems. While single-core systems included only one processor core on a chip, current multi-core processors include up to tens ...

    • TaskInsight: Understanding Task Schedules Effects on Memory and Performance 

      Ceballos, Germán; Grass, Thomas; Hugo, Andra; Black-Schaffer, David (Association for Computing Machinery, 2017-02)
      Text en actes de congrés
      Accés obert
      Recent scheduling heuristics for task-based applications have managed to improve their by taking into account memory-related properties such as data locality and cache sharing. However, there is still a general lack of ...
