    • Auto-tuned OpenCL kernel co-execution in OmpSs for heterogeneous systems 

      Pérez, Borja; Stafford, Esteban; Bosque Orero, José Luis; Beivide Palacio, Ramon; Mateo Bellido, Sergi; Teruel García, Xavier; Martorell Bofill, Xavier; Ayguadé Parra, Eduard (2019-03-01)
      Article
      Open Access
      The emergence of heterogeneous systems has been very notable recently. The nodes of the most powerful computers integrate several compute accelerators, like GPUs. Profiting from such node configurations is not a trivial ...
    • Coyote: an open source simulation tool to enable RISC-V in HPC 

      Pérez, Borja; Fell, Alexander; Davis, John D. (Institute of Electrical and Electronics Engineers (IEEE), 2021)
      Conference report
      Open Access
      The confluence of technology trends and economics has reincarnated computer architecture and specifically, software-hardware co-design. We are entering a new era of a completely open ecosystem, from applications to chips ...
    • Extending OmpSs for OpenCL kernel co-execution in heterogeneous systems 

      Pérez, Borja; Stafford, Esteban; Bosque, Jose L.; Beivide Palacio, Ramon; Mateo, Sergi; Teruel, Xavier; Martorell Bofill, Xavier; Ayguadé Parra, Eduard (Institute of Electrical and Electronics Engineers (IEEE), 2017)
      Conference report
      Open Access
      Heterogeneous systems have a very high potential performance but present difficulties in their programming. OmpSs is a well known framework for task based parallel applications, which is an interesting tool to simplify the ...
    • From heterogeneous co-execution to DSAs: an overview of past, present and future research lines 

      Pérez, Borja (Barcelona Supercomputing Center, 2020)
      Conference report
      Open Access
      Heterogeneous architectures are prevalent, ranging from supercomputing to handheld devices. However, the collaboration of devices with different capabilities poses challenges of its own. This talk will introduce different ...
    • To distribute or not to distribute: The question of load balancing for performance or energy 

      Stafford, Esteban; Pérez, Borja; Bosque, Jose L.; Beivide Palacio, Ramon; Valero Cortés, Mateo (Springer, 2017)
      Conference report
      Open Access
      Heterogeneous systems are nowadays a common choice in the path to Exascale. Through the use of accelerators they offer outstanding energy efficiency. The programming of these devices employs the host-device model, which ...
