    • Clupiter: a Raspberry Pi mini-supercomputer for educational purposes 

      Rodríguez-Iglesias, Alonso; Martín, María J.; Touriño, Juan (Institute of Electrical and Electronics Engineers, 2024)
      [Abstract]: The main objective of this work is to bring supercomputing and parallel processing closer to non-specialized audiences by building a Raspberry Pi cluster, called Clupiter, which emulates the operation of a ...

    • Dense Matrix Multiplication Algorithms and Performance Evaluation of HPCC in 81 Nodes IBM Power 8 Architecture 

      Estévez Ruiz, Eduardo Patricio; Caluña, Giovanny; Jiménez Patiño, Fabian Rodolfo; López, Joaquín; Thirumuruganandham, Saravana Prakash (MDPI, 2021-08)
      [Abstract] Optimizing HPC systems based on performance factors and bottlenecks is essential for designing an HPC infrastructure with the best characteristics and at a reasonable cost. Such insight can only be achieved ...

    • Sparse Givens QR Factorization on a Multiprocessor 

      Touriño, Juan; Doallo, Ramón; Zapata, E.L. (IEEE Computer Society, 1996-06-01)
      [Abstract] We present a parallel algorithm for the QR factorization with column pivoting of a sparse matrix by means of Givens rotations. Nonzero elements of the matrix M to be decomposed are stored in a one dimensional ...
