    • A New Task Graph Model for Mapping Message Passing Applications 

      Roig Mateu, Concepció; Ripoll, A.; Guirado Fernández, Fernando (Institute of Electrical and Electronics Engineers, 2007)
      The exploitation of parallelism in a message passing platform implies a previous modeling phase of the parallel application as a task graph, which properly reflects its temporal behavior. In this paper, we analyze the ...
    • A Pipeline-Based Approach for Mapping Message-Passing Applications with an Input Data Stream 

      Guirado Fernández, Fernando; Ripoll, A.; Roig Mateu, Concepció; Luque, Emilio (Springer Verlag, 2004)
      Pipeline applications simultaneously execute different instances from an input data set. Performance parameters for such applications are latency (the time taken to process an individual data set) and throughput (the ...
    • A Secure Elliptic Curve-Based RFID Protocol 

      Martínez Rodríguez, Santi; Valls Marsal, Magda; Roig Mateu, Concepció; Miret, Josep M. (Josep Maria); Giné, Francesc (Springer Verlag, 2009)
      Nowadays, the use of Radio Frequency Identification (RFID) systems in industry and stores has increased. Nevertheless, some of these systems present privacy problems that may discourage potential users. Hence, high ...
    • An SLA and power-saving scheduling consolidation strategy for shared and heterogeneous clouds 

      Vilaplana Mayoral, Jordi; Mateo Fornés, Jordi; Teixidó Torrelles, Ivan; Solsona Tehàs, Francesc; Giné, Francesc; Roig Mateu, Concepció (Springer Verlag, 2015)
      This paper presents a power-aware scheduling policy algorithm of Virtual Machines into nodes called Green Cloud (GreenC) for Heterogeneous cloud systems. GreenC takes into account optimal assignments according to physical ...
    • Efficient Mapping for Message-Passing Applications Using the TTIG Model: A Case Study in Image Processing 

      Roig Mateu, Concepció; Ripoll, A.; Borrás, Javier; Luque, Emilio (Springer Verlag, 2001)
      In this paper we describe the development and performance of an image processing application with functional parallelism within the PVM framework. The temporal behaviour of the application is statically modelled with ...
    • Enhancing throughput for streaming applications running on cluster systems 

      Guirado Fernández, Fernando; Roig Mateu, Concepció; Ripoll, A. (Elsevier, 2013)
      The exploitation of throughput in a parallel application that processes an input data stream is a difficult challenge. For typical coarse-grain applications, where the computation time of tasks is greater than their ...
    • Exploiting Knowledge of Temporal Behaviour in Parallel Programs for Improving Distributed Mapping 

      Roig Mateu, Concepció; Ripoll, A.; Senar, M.A.; Guirado Fernández, Fernando; Luque, Emilio (Springer Verlag, 2000)
      In the distributed processing area, mapping and scheduling are very important issues in order to exploit the gain from parallelization. The generation of efficient static mapping techniques implies a previous modelling ...
    • Exploiting Throughput for Pipeline Execution in Streaming Image Processing Applications 

      Guirado Fernández, Fernando; Ripoll, A.; Roig Mateu, Concepció; Hernàndez, A.; Luque, Emilio (Springer Verlag, 2006)
      There is a large range of image processing applications that act on an input sequence of image frames that are continuously received. Throughput is a key performance measure to be optimized when executing them. In this ...
    • Predicting the Best Mapping for Efficient Exploitation of Task and Data Parallelism 

      Guirado Fernández, Fernando; Ripoll, A.; Roig Mateu, Concepció; Yuan, X.; Luque, Emilio (Springer Verlag, 2003)
      The detection and exploitation of different kinds of parallelism, task parallelism and data parallelism often leads to efficient parallel programs. This paper presents a simulation environment to predict the best mapping ...
