On the instrumentation of OpenMP and OmpSs Tasking constructs
Servat, Harald; Teruel, Xavier; Llort Sánchez, Germán; Duran González, Alejandro; Giménez, J.; Martorell Bofill, Xavier; Ayguadé Parra, Eduard; Labarta Mancho, Jesús José (Springer, 2012)
Text en actes de congrés
Accés obertParallelism has become more and more commonplace with the advent of the multicore processors. Although different parallel pro- gramming models have arisen to exploit the computing capabilities of such processors, ... -
OpenMP tasking analysis for programers
Teruel, Xavier; Barton, Christopher; Duran González, Alejandro; Martorell Bofill, Xavier; Ayguadé Parra, Eduard; Unnikrishnan, Priya; Zhang, Guansong; Silvera, Raul (2009-11)
Text en actes de congrés
Accés restringit per política de l'editorialAs 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 obertTasking 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 obertArray-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 obertThe 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 obertNascent 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 obertScatter-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)
Text en actes de congrés
Accés restringit per política de l'editorialHeterogeneous systems are an important trend in the future of supercomputers, yet they can be hard to program and developers still lack powerful tools to gain understanding about how well their accelerated codes perform ... -
Towards task-parallel reductions in OpenMP
Ciesko, Jan; Mateo, Sergi; Teruel, Xavier; Martorell Bofill, Xavier; Ayguadé Parra, Eduard; Labarta Mancho, Jesús José; Duran, Alex; De Supinski, Bronis; Olivier, Stephen; Li, Kelvin; Eichenberger, Alexandre (Springer, 2015)
Text en actes de congrés
Accés restringit per política de l'editorialReductions represent a common algorithmic pattern in many scientific applications. OpenMP* has always supported them on parallel and worksharing constructs. OpenMP 3.0’s tasking constructs enable new parallelization ...
