    • A dynamic periodicity detector: application to speedup computation 

      Freitag, Fèlix; Corbalán González, Julita; Labarta Mancho, Jesús José (IEEE, 2001-04)
      Text en actes de congrés
      Accés obert
      We propose a dynamic periodicity detector (DPD) for the estimation of periodicities in data series obtained from the execution of applications. We analyze the algorithm used by the periodicity detector and its performance ...
    • A trace-scaling agent for parallel application tracing. 

      Freitag, Fèlix; Caubet Serrabou, Jordi; Labarta Mancho, Jesús José (IEEE, 2002)
      Text en actes de congrés
      Accés obert
      Tracing and performance analysis tools are an important component in the development of high performance applications. Tracing parallel programs with current tracing tools, however, easily leads to large trace files with ...
    • A demand based algorithm for rapid updating of replicas 

      Acosta Elías, J. Jesús; Navarro Moldes, Leandro (IEEE, 2002)
      Text en actes de congrés
      Accés obert
      In many Internet scale replicated system, not all replicas can be dealt with in the same way, since some will be in greater demand than others. In the case of weak consistency algorithms, we have observed that updating first ...
    • Open CSCW systems: will ODP help? 

      Navarro Moldes, Leandro; Prinz, Wolfgang; Rodden, Tom (IEEE, 1992-06-09)
      Text en actes de congrés
      Accés obert
      This paper is concerned with the role of Open Distributed Processing systems within the development of cooperative systems. In particular, we focus on the need to provide Open CSCW systems and their impact on distributed ...
    • WWG: a wide-area infrastructure to support groups. 

      Marquès Puig, Joan Manel; Navarro Moldes, Leandro (Association for Computing Machinery, 2001)
      Text en actes de congrés
      Accés obert
      Group learning at Internet scale is becoming more frequent in university courses. This complex process requires support by distributed computing learning support infrastructures. This paper describes the design of WWG: a ...
    • Decentralized vs. centralized economic coordination of resource allocation in grids 

      Eymann, Torsten; Reinicke, Michael; Ardáiz Villanueva, Óscar; Artigas Vidal, Pau; Díaz de Cerio Ripalda, Luis Manuel; Freitag, Fèlix; Meseguer Pallarès, Roc; Navarro Moldes, Leandro; Royo Vallés, María Dolores; Sanjeevan, Kanapathipillai (Springer Verlag, 2003-02-13)
      Text en actes de congrés
      Accés obert
      Application layer networks are software architectures that allow the provisioning of services requiring a huge amount of resources by connecting large numbers of individual computers, like in Grid or Peer-to-Peer ...
    • ULabGrid, an infrastructure to develop distant laboratories for undergrad students over a Grid 

      Ardáiz Villanueva, Óscar; Artigas Vidal, Pau; Díaz de Cerio Ripalda, Luis Manuel; Freitag, Fèlix; Meseguer Pallarès, Roc; Navarro Moldes, Leandro; Sanjeevan, Kanapathipillai; Royo Vallés, María Dolores (Springer Verlag, 2003-02-13)
      Text en actes de congrés
      Accés obert
      Nowadays, there is a big discussion about two different topics: how distance learning and the old fashioned learning can be improved using the new technologies. In both cases, there are many collaborative tools based on ...
    • Exploring the catallactic coordination approach for peer-to-peer systems 

      Ardáiz Villanueva, Óscar; Artigas Vidal, Pau; Eymann, Torsten; Freitag, Fèlix; Meseguer Pallarès, Roc; Navarro Moldes, Leandro; Reinicke, Michael (Springer Verlag, 2003)
      Text en actes de congrés
      Accés obert
      Efficient discovery and resource allocation is one of the challenges of current Peer-to-Peer systems. In centralized approaches, the user requests can be matched to the fastest, cheapest or most available resource. This ...
    • On the scalability of tracing mechanisms 

      Freitag, Fèlix; Caubet Serrabou, Jordi; Labarta Mancho, Jesús José (Springer Verlag, 2002)
      Text en actes de congrés
      Accés obert
      Performance analysis tools are an important component of the parallel program development and tuning cycle. To obtain the raw performance data, an instrumented application is run with probes that take measures of specific ...
    • MOCCA: an environment for CSCW applications. 

      Benford, Steve; Mariani, John A.; Navarro Moldes, Leandro; Prinz, Wolfgang; Rodden, Tom (Association for Computing Machinery, 1993)
      Text en actes de congrés
      Accés obert
      Our belief is that future, Computer Supported Cooperative Work will by necessity involve a heterogeneous collection of applications, paradigms and models and that no single system will meet all the requirements of all ...
