The Distributed Systems group is currently working on economics oriented distributed systems, particularly on resource allocation mechanisms for Grid and peer-to-peer, on decentralized systems applied to Ambient Networks, and on applications supporting cooperative learning (CSCL).

Projects:

- Catnets: Economic algorithms for resource allocation.

- SORMA: Development of methods and tools for an efficient market-based allocation of resources, through a self-organizing resource management system, using market-driven models supported by extensions for Grid infrastructures. )

- Grid4All: Aims at enabling domestic users, non-profit organisations such as schools, and small enterprises, to share their resources and to access massive Grid resources when needed, envisioning a future in which access to resources is democratised, readily available, cooperative, and inexpensive.

  • The catallaxy approach for decentralized economic-based allocation in Grid resource and service markets. 

    Ardáiz Villanueva, Óscar; Artigas Vidal, Pau; Eymann, Torsten; Freitag, Fèlix; Navarro Moldes, Leandro; Reinicke, Michael (Springer, 2006)
    Article
    Open Access
    Efficient resource allocation in dynamic large-scale environments is one of the cha llenges of Grids. In centralized economic-based allocation approaches, the user requests can be matched to the fastest, cheapest or most ...
  • 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 ...
  • Assessing a distributed market infrastructure for economics-based service selection 

    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 ...
  • Performance measuring framework for grid market middleware 

    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 ...
  • A Hayekian self-organization approach to service allocation in computing systems 

    Eymann, Torsten; Reinicke, Michael; Freitag, Fèlix; Navarro Moldes, Leandro; Ardáiz Villanueva, Óscar; Artigas Vidal, Pau (Elsevier, 2005)
    Article
    Open Access
    Future ‘on-demand’ computing systems, often depicted as potentially large scale and complex Service-Oriented Architectures, will need innovative management approaches for controlling and matching services demand and supply. ...
  • A catallactic market for data mining services. 

    Joita, Liviu; Rana, Omer; Freitag, Fèlix; Chao, Isaac; Chacín Martínez, Pablo; Navarro Moldes, Leandro; Ardáiz Villanueva, Óscar (2007)
    Article
    Open Access
    We describe a Grid market for exchanging data mining services based on the Catallactic market mechanism proposed by von Hayek. This market mechanism allows selection between multiple instances of services based on operations ...
  • 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 ...
  • WWG: a wide-area infrastructure for group work 

    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 ...
