  • Integration of decentralized economic models for resource self-management in application layer networks 

    Chacín Martínez, Pablo; Freitag, Fèlix; Navarro Moldes, Leandro; Chao, Isaac; Ardáiz Villanueva, Óscar (Springer, 2005)
    Conference report
    Open Access
    Resource allocation is one of the challenges for self-management of large scale distributed applications running in a dynamic and heterogeneous environment. Considering Application Layer Networks (ALN) as a general term ...
  • Elaborating a decentralized market information system 

    Brunner, René; Freitag, Fèlix (Springer, 2007)
    Conference lecture
    Open Access
    A Decentralized Market Information System (DMIS) that aggregates and provides information about markets is an important component for achieving markets in Grid and Peer-to-Peer systems. The proposed work is the development ...

    Brunner, René; Chao, Isaac; Chacín Martínez, Pablo; Freitag, Fèlix; Navarro Moldes, Leandro; Ardáiz Villanueva, Óscar; Joita, Liviu; Rana, Omer (Springer, 2007)
    Conference lecture
    Open Access
    Service selection is an important issue for market-oriented Grid infrastructures. However, few results have been published on the use and evaluation of market models in deployed prototypes, making it difficult to assess ...
  • Predicting MPI buffer addresses. 

    Freitag, Fèlix; Farreras Esclusa, Montserrat; Cortés, Toni; Labarta Mancho, Jesús José (Springer, 2004)
    Conference lecture
    Open Access
    Communication latencies have been identified as one of the performance limiting factors of message passing applications in clusters of workstations/multiprocessors. On the receiver side, message-copying operations contribute ...

    Freitag, Fèlix; Chacín Martínez, Pablo; Chao, Isaac; Brunner, René; Navarro Moldes, Leandro; Ardáiz Villanueva, Óscar (Springer, 2007)
    Conference lecture
    Open Access
    Current implementations of Grid infrastructures provide frameworks which aim at achieve on-demand computing. In such a scenario, contribution and use of resources will be governed by business models. The challenge is to ...
  • Group-awareness for mobile cooperative learning. 

    Meseguer Pallarès, Roc; Navarro Moldes, Leandro; Reyes Muñoz, María Angélica (IEEE, 2006-11-16)
    Conference report
    Open Access
    Collaborative learning traditionally relies on the arrangement of space and physical artifacts to mediate group activities. Our claim is that CSCL environments should enhance collaborative learning in a complementary way ...

    Marquès Puig, Joan Manel; Navarro Moldes, Leandro (IEEE, 2001)
    Conference report
    Open Access
    Group learning at Internet scale is becoming more frequent in university courses. This complex process requires support by distributed computing learning infrastructures. This paper describes the design of WWG: a distributed ...
  • P2P architecture for scientific collaboration. 

    Mitre Silva, José; Navarro Moldes, Leandro (IEEE, 2004)
    Conference report
    Open Access
    P2P networks are often associated with file exchange applications among private users. However, their features make them suitable for other uses. In this paper we present a P2P architecture for scientific collaboration ...
  • Extending the scope of asynchronous collaboration: a matter of being autonomous and self-sufficient 

    Marquès Puig, Joan Manel; Navarro Moldes, Leandro; Daradoumis, Athanasios (IEEE, 2004-06)
    Conference report
    Open Access
    Asynchronous collaborative applications and systems have to deal with complexities associated with interaction nature, idiosyncrasy of groups and technical and administrative issues. Inclusion of requirements derived from ...
