    • Adding tightly-integrated task scheduling acceleration to a RISC-V multi-core processor 

      Morais, Lucas; Silva, Vitor; Goldman, Alfredo; Álvarez Martínez, Carlos; Bosch Pons, Jaume; Frank, Michael; Araujo, Guido (Association for Computing Machinery (ACM), 2019)
      Conference report
      Open Access
      Task Parallelism is a parallel programming model that provides code annotation constructs to outline tasks and describe how their pointer parameters are accessed so that they might be executed in parallel, and asynchronously, ...
    • Asynchronous runtime for task-based dataflow programming models 

      Bosch Pons, Jaume (Universitat Politècnica de Catalunya, 2017-07)
      Master thesis
      Open Access
      Covenantee:   Barcelona Supercomputing Center
      The importance of parallel programming is increasing year after year since the power wall popularized multi-core processors, and with them, shared memory parallel programming models. In particular, task-based programming ...
    • Asynchronous runtime with distributed manager for task-based programming models 

      Bosch Pons, Jaume; Álvarez Martínez, Carlos; Jiménez González, Daniel; Martorell Bofill, Xavier; Ayguadé Parra, Eduard (2020-09)
      Article
      Restricted access - publisher's policy
      Parallel task-based programming models, like OpenMP, allow application developers to easily create a parallel version of their sequential codes. The standard OpenMP 4.0 introduced the possibility of describing a set of ...
    • Breaking master-slave model between host and FPGAs 

      Bosch Pons, Jaume; Vidal, Miquel; Filgueras Izquierdo, Antonio; Álvarez Martínez, Carlos; Jiménez González, Daniel; Martorell Bofill, Xavier; Ayguadé Parra, Eduard (Association for Computing Machinery (ACM), 2020)
      Conference lecture
      Restricted access - publisher's policy
      This paper proposes to enhance current task-based programming models by breaking their current master-slave approach between the main processor and its hardware accelerators. As a proof-of-concept, it presents an extension ...
    • Design and implementation of an architecture-aware hardware runtime for heterogeneous systems 

      de Haro Ruiz, Juan Miguel; Bosch Pons, Jaume; Jiménez González, Daniel (Barcelona Supercomputing Center, 2020-05)
      Conference report
      Open Access
      Parallel computing has become the norm to gain performance in multicore and heterogeneous systems. Many programming models allow to exploit this parallelism with easy to use tools. In this work we focus on task-based ...
    • Exploiting parallelism on GPUs and FPGAs with OmpSs 

      Bosch Pons, Jaume; Filgueras Izquierdo, Antonio; Vidal, Miquel; Jiménez González, Daniel; Álvarez Martínez, Carlos; Martorell, Xavier (Association for Computing Machinery (ACM), 2017)
      Conference report
      Open Access
      This paper presents the OmpSs approach to deal with heterogeneous programming on GPU and FPGA accelerators. The OmpSs programming model is based on the Mercurium compiler and the Nanos++ runtime. Applications are annotated ...
    • 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. ...
    • Reorganització del runtime Nanos++ 

      Bosch Pons, Jaume (Universitat Politècnica de Catalunya, 2015-06)
      Bachelor thesis
      Open Access
      Aquest projecte proposa una reorganització del sistema de gestió de les dependències entre tasques a Nanos++ (runtime del model de programació OmpSs) amb l'objectiu de reduir la contenció d'accés a aquestes estructures, ...
    • Supporting task creation inside FPGA devices 

      Bosch Pons, Jaume; Álvarez Martínez, Carlos; Jiménez González, Daniel (Barcelona Supercomputing Center, 2019-05-07)
      Conference report
      Open Access
      The most common model to use co-processors/accelerators is the master-slave model where the slaves (coprocessors/ accelerators) are driven by a general purpose cpu. This simplifies the management of the accelerators because ...
    • TaskGenX: A Hardware-Software Proposal for Accelerating Task Parallelism 

      Chronaki, Kallia; Casas, Marc; Moreto Planas, Miquel; Bosch Pons, Jaume; Badia Sala, Rosa Maria (Springer, 2018-05-29)
      Conference lecture
      Open Access
      As chip multi-processors (CMPs) are becoming more and more complex, software solutions such as parallel programming models are attracting a lot of attention. Task-based parallel programming models offer an appealing approach ...
    • The AXIOM software layers
