      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)

      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 Querol, 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
      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 Querol, 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 Marenostrum experimental exascale platform (MEEP) 

      Fell, Alexander; Mazure, Daniel J.; Garcia, Teresa C.; Perez, Borja; Teruel, Xavier; Wilson, Pete; Davis, John D. (Publishing center of the South Ural State University, 2021)
      Article
      Accés obert
      Nascent Open Source Instruction Set Architectures such as OpenPOWER or RISC-V, allow software/hardware co-designers to fully utilize the underlying hardware, modify it or extend it based on their needs. In this paper, we ...
    • The OmpSs reductions model and how to deal with scatter-updates 

      Ciesko, Jan; Mateo Bellido, Sergi; Teruel, Xavier; Beltran Querol, 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 Mancho, Jesús José (Springer, 2016)
