    With the addition of the OpenMP* tasking model, programmers are able to improve and extend the parallelization opportunities of their codes. Programmers can also distribute the creation of tasks using a worksharing construct, ...
  • Approaches for Task Affinity in OpenMP 

    Terboven, Christian; Hahnfeld, Jonas; Teruel, Xavier; Mateo, Sergi; Duran, Alejandro; Klemm, Michael; Olivier, Stephen L.; Supinski, Bronis R. (Springer International Publishing, 2016-09-21)

    As of 2008, the OpenMP 3.0 standard includes task support allowing programmers to exploit irregular parallelism. Although several compilers are providing support for this new feature there has not been extensive investigation ...
  • OpenMP tasks in IBM XL compilers 

    Teruel, Xavier; Unnikrishnan, Priya; Martorell Bofill, Xavier; Ayguadé Parra, Eduard; Silvera, Raul; Zhang, Guansong; Tiotto, Ettore (Association for Computing Machinery (ACM), 2008)
    Comunicació de congrés
    Accés obert
    Tasking is the most significant feature included in the new OpenMP 3.0 standard. It was introduced to handle unstructured parallelism and broaden the range of applications that can be parallelized by OpenMP. This paper ...
  • Scaling irregular array-type reductions in OmpSs 

    Ciesko, Jan; Mateo Bellido, Sergi; Teruel, Xavier; Beltran, Vicenç (Barcelona Supercomputing Center, 2015-05-05)
    Text en actes de congrés
    Accés obert
    Array-type reductions represent a frequently occurring algorithmic pattern in many scientific applications. A special case occurs if array elements are accessed in a non-linear, often random manner, which makes their ...
  • Task-parallel reductions in OpenMP and OmpSs 

    Ciesko, Jan; Mateo, Sergi; Teruel, Xavier; Beltran, Vicenç; Martorell Bofill, Xavier; Badia,, R.M.; Ayguadé Parra, Eduard; Labarta Mancho, Jesús José (Springer, 2014)
    Text en actes de congrés
    Accés obert
    The wide adoption of parallel processing hardware in mainstream computing as well as the raising interest for efficient parallel programming in the developer community increase the demand for parallel programming model ...
  • The OmpSs reductions model and how to deal with scatter-updates 

    Ciesko, Jan; Mateo Bellido, Sergi; Teruel, Xavier; Beltran, Vicenç; Martorell Bofill, Xavier; Badia Sala, Rosa Maria; Labarta Mancho, Jesús José (Barcelona Supercomputing Center, 2015-05-05)
    Text en actes de congrés
    Accés obert
    Scatter-updates represent a reoccurring algorithmic pattern in many scientific applications. Their scalable execution on modern systems is difficult due to performance limitations introduced by their irregular memory access ...
  • The secrets of the accelerators unveiled: tracing heterogeneous executions through OMPT 

    Llort, German; Filgueras Izquierdo, Antonio; Jiménez-González, Daniel; Servat, Harald; Teruel, Xavier; Mercadal, Estanislao; Álvarez, Carlos; Giménez, Judit; Martorell Bofill, Xavier; Ayguadé Parra, Eduard; Labarta, Jesús (Springer, 2016)
