    • A hardware runtime for task-based programming models 

      Tan, Xubin; Bosch, Jaume; Álvarez, Carlos; Jiménez González, Daniel; Ayguadé Parra, Eduard; Valero Cortés, Mateo (2019-09-01)
      Article
      Open Access
      Task-based programming models such as OpenMP 5.0 and OmpSs are simple to use and powerful enough to exploit task parallelism of applications over multicore, manycore and heterogeneous systems. However, their software-only ...

    • Application acceleration on FPGAs with OmpSs@FPGA 

      Bosch, Jaume; Tan, Xubin; Filgueras Izquierdo, Antonio; Vidal, Miquel; Mateu, Marc; Jiménez-González, Daniel; Álvarez, Carlos; Martorell Bofill, Xavier; Ayguadé Parra, Eduard; Labarta Mancho, Jesús José (Institute of Electrical and Electronics Engineers (IEEE), 2019)
      Conference report
      Open Access
      OmpSs@FPGA is the flavor of OmpSs that allows offloading application functionality to FPGAs. Similarly to OpenMP, it is based on compiler directives. While the OpenMP specification also includes support for heterogeneous ...

    • Characterizing and improving the performance of many-core task-based parallel programming runtimes 

      Bosch, Jaume; Tan, Xubin; Álvarez Martínez, Carlos; Jiménez González, Daniel; Martorell Bofill, Xavier; Ayguadé Parra, Eduard (2017)
      Conference report
      Restricted access - publisher's policy
      Parallel task-based programming models like OpenMP support the declaration of task data dependences. This information is used to delay the task execution until the task data is available. The dependences between tasks are ...

    • General purpose task-dependence management hardware for task-based dataflow programming models 

      Tan, Xubin; Bosch, Jaume; Vidal, Miquel; Alvarez, Carlos; Jimenez-Gonzalez, Daniel; Ayguadé Parra, Eduard; Valero Cortés, Mateo (Institute of Electrical and Electronics Engineers (IEEE), 2017)
      Conference report
      Restricted access - publisher's policy
      Task-based programming models such as OpenMP, IntelTBB and OmpSs offer the possibility of expressing dependences among tasks to drive their execution at runtime. Managing these dependences introduces noticeable overheads ...

    • Hardware runtime management for task-based programming models 

      Tan, Xubin (Universitat Politècnica de Catalunya, 2018-11-26)
      Doctoral thesis
      Open Access
      Task-based programming models allow programmers to express applications as a collection of tasks with dependences. They are simple to use and greatly improve programmability by using software runtimes to exploit task ...

    • Mont-Blanc 2020: Towards scalable and power efficient European HPC processors 

      Armejach Sanosa, Adrià; Brank, Bine; Cortina Guardia, Jordi; Dolique, François; Hayes, Timothy; Ho, Nam; Lagadec, Pierre-Axel; Lemaire, Romain; López Paradís, Guillem; Marliac, Laurent; Moretó Planas, Miquel; Marcuello Pascual, Pedro; Pleiter, Dirk; Tan, Xubin; Derradji, Said (Institute of Electrical and Electronics Engineers (IEEE), 2021)
      Conference report
      Open Access
      The Mont-Blanc 2020 (MB2020) project has triggered the development of the next generation industrial processor for Big Data and High Performance Computing (HPC). MB2020 is paving the way to the future low-power European ...

    • Performance analysis of a hardware accelerator of dependence management for taskbased dataflow programming models 

      Tan, Xubin; Bosch Pons, Jaume; Jiménez González, Daniel; Álvarez Martínez, Carlos; Ayguadé Parra, Eduard; Valero Cortés, Mateo (Institute of Electrical and Electronics Engineers (IEEE), 2016)
      Conference report
      Open Access
      Along with the popularity of multicore and manycore, task-based dataflow programming models obtain great attention for being able to extract high parallelism from applications without exposing the complexity to programmers. ...

    • Picos, a hardware task-dependence manager for task-based dataflow programming models 

      Tan, Xubin; Bosch, Jaume; Vidal, Miquel; Álvarez, Carlos; Jiménez-González, Daniel; Ayguadé Parra, Eduard; Valero Cortés, Mateo (Institute of Electrical and Electronics Engineers (IEEE), 2017)
      Conference report
      Open Access
      Task-based programming Task-based programming models such as OpenMP, Intel TBB and OmpSs are widely used to extract high level of parallelism of applications executed on multi-core and manycore platforms. These programming ...

    • Task dependences management hardware acceleration for task-based dataflow programming models 

      Tan, Xubin; Álvarez Martínez, Carlos; Jiménez González, Daniel; Ayguadé Parra, Eduard; Valero Cortés, Mateo (Barcelona Supercomputing Center, 2015-05-05)
      Conference report
      Open Access
      Task-based programming models have gained a lot of attention for being able to explore high parallelism over multicore and manycore, while hiding the difficulties of parallel programming. For applications with moderate ...
