    • Design and Implementation of MapReduce using the PGAS Programming Model with UPC 

      Teijeiro, Carlos; López Taboada, Guillermo; Touriño, Juan; Doallo Biempica, Ramón (IEEE Computer Society, 2012-01-03)
      [Abstract] MapReduce is a powerful tool for processing large data sets used by many applications running in distributed environments. However, despite the increasing number of computationally intensive problems that require ...
    • High Performance Java Remote Method Invocation for Parallel Computing on Clusters 

      López Taboada, Guillermo; Teijeiro, Carlos; Touriño, Juan (IEEE Computer Society, 2007-11-12)
      [Abstract] This paper presents a more efficient Java remote method invocation (RMI) implementation for high-speed clusters. The use of Java for parallel programming on clusters is limited by the lack of efficient communication ...
    • Performance Evaluation of MPI, UPC and OpenMP on Multicore Architectures 

      Mallón, Damián A.; López Taboada, Guillermo; Teijeiro, Carlos; Touriño, Juan; Fraguela, Basilio B.; Gómez, Andrés; Doallo Biempica, Ramón; Mouriño, José C. (Springer, 2009)
      [Abstract] The current trend to multicore architectures underscores the need of parallelism. While new languages and alternatives for supporting more efficiently these systems are proposed, MPI faces this new challenge. ...
    • Performance Evaluation of Unified Parallel C Collective Communications 

      López Taboada, Guillermo; Teijeiro, Carlos; Touriño, Juan; Fraguela, Basilio B.; Doallo Biempica, Ramón; Mouriño, José C.; Mallón, Damián A.; Gómez, Andrés (IEEE Computer Society, 2009-07-17)
      [Abstract] Unified Parallel C (UPC) is an extension of ANSI C designed for parallel programming. UPC collective primitives, which are part of the UPC standard, increase programming productivity while reducing the communication ...
