    • A Space and Time Sharing Scheduling Approach for PVM Non-dedicated Clusters 

      Hanzich, Mauricio; Giné, Francesc; Hernández Budé, Porfidio; Solsona Tehàs, Francesc; Luque, Emilio (Springer Verlag, 2005)
      Wasted resources are a common reality in open laboratories in any University today [2]. Our aim is to take advantage of those resources to do parallel computation without disturbing the local tasks excessively. In order ...
    • CISNE-P: a global scheduling oriented to NOW environments 

      Torchinsky, Matias; Hanzich, Mauricio; Hernández Budé, Porfidio; Luque, Emilio; Giné, Francesc; Solsona Tehàs, Francesc; Lérida Monsó, Josep Lluís (Iberoamerican Science & Technology Education Consortium, 2007)
      In this work, we present an integral scheduling system for non-dedicated clusters, termed CISNE-P, which ensures the performance required by the local applications, while simultaneously allocating cluster resources to ...
    • CISNE: A New Integral Approach for Scheduling Parallel Applications on Non-dedicated Clusters 

      Hanzich, Mauricio; Giné, Francesc; Hernández Budé, Porfidio; Solsona Tehàs, Francesc; Luque, Emilio (Springer Verlag, 2005)
      Our main interest is oriented towards keeping both local and parallel jobs together in a non-dedicated cluster. In order to obtain some profits from the parallel applications, it is important to consider time and space ...
    • Cooperating CoScheduling: A Coscheduling Proposal Aimed at Non-Dedicated Heterogeneous NOWs 

      Giné, Francesc; Solsona Tehàs, Francesc; Hanzich, Mauricio; Hernández Budé, Porfidio; Luque, Emilio (Springer Verlag, 2007)
      Implicit coscheduling techniques applied to non-dedicated homogeneous Networks Of Workstations (NOWs) have shown they can perform well when many local users compete with a single parallel job. Implicit coscheduling deals ...
    • Coscheduling techniques and monitoring tools for non-dedicated cluster computing 

      Solsona Tehàs, Francesc; Giné, Francesc; Hernández Budé, Porfidio; Luque, Emilio (Iberoamerican Science & Technology Education Consortium, 2001)
      Our efforts are directed towards the understanding of the coscheduling mechanism in a NOW system when a parallel job is executed jointly with local workloads, balancing parallel performance against the local interactive ...
    • Coscheduling under Memory Constraints in a NOW 

      Giné, Francesc; Solsona Tehàs, Francesc; Hernández Budé, Porfidio; Luque, Emilio (Springer Verlag, 2001)
      Networks of Workstations (NOW) have become important and cost-effective parallel platforms for scientific computations. In practice, a NOW system is heterogeneous and non-dedicated. These two unique factors make scheduling ...
    • Designing an effective P2P system for a VoD system to exploit the multicast communication 

      Yang, X. Y.; Cores Prado, Fernando; Hernández Budé, Porfidio; Ripoll, A.; Luque, Emilio (Elsevier, 2010)
      A distributed video-on-demand system (DVoD) with multiple server-nodes is a cost-effective and faulttolerant solution for a high scalable enterprise video-on-demand (VoD) system. However, such a serveroriented design is ...
    • Dynamic Distributed Collaborative Merging Policy to Optimize the Multicasting Delivery Scheme 

      Yang, X. Y.; Hernández Budé, Porfidio; Cores Prado, Fernando; Ripoll, A.; Suppi, Remo; Luque, Emilio (Springer Verlag, 2005)
      The advance of Internet 2 and the proliferation of switches and routers with level three functionalities made the multicast one of the most feasible video streaming delivering techniques for the near future. Assuming ...
    • Enhancing Prediction on Non-dedicated Clusters 

      Lérida Monsó, Josep Lluís; Solsona Tehàs, Francesc; Giné, Francesc; García, J. R.; Hanzich, Mauricio; Hernández Budé, Porfidio (Springer Verlag, 2008)
      In this paper, we present a scheduling scheme to estimate the turnaround time of parallel jobs on a heterogeneous and non-dedicated cluster or NoW(Network of Workstations). This scheme is based on an ...
    • MetaLoRaS: A Re-scheduling and Prediction MetaScheduler for Non-dedicated Multiclusters 

      Lérida Monsó, Josep Lluís; Solsona Tehàs, Francesc; Giné, Francesc; Hanzich, Mauricio; García, J. R.; Hernández Budé, Porfidio (Springer Verlag, 2007)
      Recently, Multicluster environments have become more important in the high-performance computing world. However, less attention has been paid to non-dedicated Multiclusters. We are developing MetaLoRaS, an efficient ...
    • On/off-line prediction applied to job scheduling on non-dedicated NOWs 

      Hanzich, Mauricio; Hernández Budé, Porfidio; Giné, Francesc; Solsona Tehàs, Francesc; Lérida Monsó, Josep Lluís (Springer Verlag, 2011)
      This paper proposes a prediction engine designed for non-dedicated clusters, which is able to estimate the turnaround time for parallel applications, even in the presence of serial workload of the workstation owner. The ...
    • Resource Matching in Non-dedicated Multicluster Environments 

      Lérida Monsó, Josep Lluís; Solsona Tehàs, Francesc; Giné, Francesc; Hernández Budé, Porfidio; García, J. R. (Springer Verlag, 2008)
      We are interested in making use of Multiclusters to execute parallel applications. The present work is developed within the M-CISNE project. MCISNE is a non-dedicated and heterogeneous Multicluster environment which includes ...
    • Using On-the-Fly Simulation for Estimating the Turnaround Time on Non-dedicated Clusters
