      [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 ...

    • Efficient Java Communication Protocols on High-speed Cluster Interconnects 

      Taboada, Guillermo L.; Touriño, Juan; Doallo, Ramón (IEEE Computer Society, 2007-02-26)
      [Abstract] This paper presents communication strategies for achieving efficient parallel and distributed Java applications on clusters with high-speed interconnects. Communication performance is critical for the overall ...

    • Evaluation of Java for General Purpose GPU Computing 

      Docampo, Jorge; Ramos Garea, Sabela; Taboada, Guillermo L.; Expósito, Roberto R.; Touriño, Juan; Doallo, Ramón (IEEE Computer Society, 2013-07-01)
      [Abstract] The presence of many-core units as accelerators has been increasing due to their ability to improve the performance of highly parallel workloads. General Purpose GPU(GPGPU) computing has allowed the graphical ...

    • High Performance Java Remote Method Invocation for Parallel Computing on Clusters 

      Taboada, Guillermo L.; Teijeiro Barjas, 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 ...

    • MREv: An Automatic MapReduce Evaluation Tool for Big Data Workloads 

      Veiga, Jorge; Expósito, Roberto R.; Taboada, Guillermo L.; Touriño, Juan (Elsevier, 2015)
      [Abstract]: The popularity of Big Data computing models like MapReduce has caused the emergence of many frameworks oriented to High Performance Computing (HPC) systems. The suitability of each one to a particular use case ...

    • Non-blocking Java Communications Support on Clusters 

      Taboada, Guillermo L.; Touriño, Juan; Doallo, Ramón (Springer, 2006)
      [Abstract] This paper presents communication strategies for supporting efficient non-blocking Java communication on clusters. The communication performance is critical for the overall cluster performance. It is possible ...

    • NPB-MPJ: NAS Parallel Benchmarks Implementation for Message-Passing in Java 

      Mallón, Damián A.; Taboada, Guillermo L.; Touriño, Juan; Doallo, Ramón (IEEE Computer Society, 2009-05-08)
      [Abstract] Java is a valuable and emerging alternative for the development of parallel applications, thanks to the availability of several Java message-passing libraries and its full multithreading support. The combination ...

    • Performance analysis of Java message-passing libraries on fast Ethernet, Myrinet and SCI clusters 

      Taboada, Guillermo L.; Touriño, Juan; Doallo, Ramón (IEEE Computer Society, 2004-01-08)
      [Abstract] The use of Java for parallel programming on clusters according to the message-passing paradigm is an attractive choice. In this case, the overall application performance will largely depend on the performance ...

    • Performance Evaluation of Big Data Frameworks for Large-Scale Data Analytics 

      Veiga, Jorge; Expósito, Roberto R.; Pardo, Xoán C.; Taboada, Guillermo L.; Touriño, Juan (IEEE Computer Society, 2017-02-06)
      [Abstract] The increasing adoption of Big Data analytics has led to a high demand for efficient technologies in order to manage and process large datasets. Popular MapReduce frameworks such as Hadoop are being replaced by ...

    • Performance Evaluation of MPI, UPC and OpenMP on Multicore Architectures
