    • Tasking in accelerators: performance evaluation 

      Toledo, Leonel; Peña, Antonio J.; Catalán, Sandra; Valero-Lara, Pedro (Institute of Electrical and Electronics Engineers (IEEE), 2019)
      Conference report
      Open Access
      In this work, we analyze the implications and results of implementing dynamic parallelism, concurrent kernels and CUDA Graphs to solve task-oriented problems. As a benchmark we propose three different methods for solving ...

    • The Design and Performance of Batched BLAS on Modern High-Performance Computing Systems 

      Dongarra, Jack; Hammarling, Sven; Higham, Nicholas J.; Relton, Samuel D.; Valero-Lara, Pedro; Zounon, Mawussi (Elsevier, 2017)
      Article
      Open Access
      A current trend in high-performance computing is to decompose a large linear algebra problem into batches containing thousands of smaller problems, that can be solved independently, before collating the results. To standardize ...

    • Towards HPC-Embedded. Case Study: Kalray and Message-Passing on NoC 

      Valero-Lara, Pedro; Krishnasamy, Ezhilmathi; Jansson, Johan (Universitatea de Vest, 2017-06)
      Article
