• closedAccess   A Runtime System for Programming Out-of-Core Matrix Algorithms-by-Tiles on Multithreaded Architectures 

      Quintana-Ortí, Gregorio; Igual, Francisco; Marqués-Andrés, Mercedes; Quintana-Orti, Enrique S.; Van de Geijn, Robert A. ACM (2012-08)
      Out-of-core implementations of algorithms for dense matrix computations have traditionally focused on optimal use of memory so as to minimize I/O, often trading programmability for performance. In this article we show how ...
    • openAccess   DMRlib: Easy-coding and Efficient Resource Management for Job Malleability 

      Iserte, Sergio; Mayo, Rafael; Quintana-Orti, Enrique S.; Pena, Antonio J. IEEE (2020-09-09)
      Process malleability has proved to have a highly positive impact on the resource utilization and global productivity in data centers compared with the conventional static resource allocation policy. However, the non-negligible ...
    • openAccess   Environment-Aware Regression for Indoor Localization based on WiFi Fingerprinting 

      Mendoza-Silva, Germán Martín; Costa, Ana Cristina; Torres-Sospedra, Joaquín; Painho, Marco; Huerta, Joaquin Institute of Electrical and Electronics Engineers (2021-04-19)
      Data enrichment through interpolation or regression is a common approach to deal with sample collection for Indoor Localization with WiFi fingerprinting. This paper provides guidelines on where to collect WiFi samples, and ...
    • closedAccess   Families of Algorithms for Reducing a Matrix to Condensed Form 

      Van Zee, Field G.; Van de Geijn, Robert A.; Quintana-Ortí, Gregorio; Elizondo, G. Joseph ACM (2012-11)
      In a recent paper it was shown how memory traffic can be diminished by reformulating the classic algorithm for reducing a matrix to bidiagonal form, a preprocess when computing the singular values of a dense matrix. The ...
    • openAccess   ROSLab Sharing ROS Code Interactively With Docker and JupyterLab 

      Cervera, Enric; del Pobil, Angel P. IEEE (2019-07-15)
      The success of the Robot Operating System (ROS) and the advance of open source ideas have radically changed and improved the experience of sharing software among members of the robotics community. Yet the lack of a suitable ...
