      The tasking model of OpenMP 4.0 supports both nesting and the definition of dependences between sibling tasks. A natural way to parallelize many codes with tasks is to first taskify the high-level functions and then to ...

    • Improving the interoperability between MPI and task-based programming models 

      Sala Penadés, Kevin; Bellón, Jorge; Farré, Pau; Teruel, Xavier; Pérez, Josep M.; Peña, Antonio J.; Holmes, Daniel; Beltran Querol, Vicenç; Labarta Mancho, Jesús José (Association for Computing Machinery (ACM), 2018)

      In this paper we propose an API to pause and resume task execution depending on external events. We leverage this generic API to improve the interoperability between MPI synchronous communication primitives and tasks. When ...

    • Overlapping communication and computation by using a hybrid MPI/SMPSs approach 

      Marjanovic, Vladimir; Pérez, Josep M.; Ayguadé Parra, Eduard; Labarta Mancho, Jesús José; Valero Cortés, Mateo (2009)
      Report de recerca
      Accés obert
      Communication overhead is one of the dominant factors that affect performance in high-performance computing systems. To reduce the negative impact of communication, programmers overlap communication and computation by using ...
