    • MetaLoRaS: A Predictable MetaScheduler for Non-dedicated Multiclusters 

      Lérida Monsó, Josep Lluís; Solsona Tehàs, Francesc; Giné, Francesc; Hanzich, Mauricio; Hernández, P.; Luque, Emilio (Springer Verlag, 2006)
      The main aim of this work is to take advantage of the computer resources of a single organization or Multicluster system to execute distributed applications efficiently without excessively damaging the local users. In ...
    • Minimizing Paging Tradeoffs Applying Coscheduling Techniques in a Linux Cluster 

      Giné, Francesc; Solsona Tehàs, Francesc; Hernandez, Porfidio; Luque, Emilio (Springer Verlag, 2003)
      Our research is focused on keeping both local and parallel jobs together in a non-dedicated cluster or NOW (Network of Workstations) and efficiently scheduling them by means of coscheduling mechanisms. The performance ...
    • Monito: A Communication Monitoring Tool for a PVM-Linux Environment 

      Solsona Tehàs, Francesc; Giné, Francesc; Lérida Monsó, Josep Lluís; Hernandez, Porfidio; Luque, Emilio (Springer Verlag, 2000)
      In this paper a new tool for monitoring the different queues of messages in a PVM environment is presented. The main aim of implementing this facility is to provide a means of capturing the bottlenecks and overheads of ...
    • Multiprogramming Level of PVM Jobs in a Non-dedicated Linux NOW 

      Giné, Francesc; Solsona Tehàs, Francesc; Barrientos, Jesus; Hernandez, Porfidio; Hanzich, Mauricio; Luque, Emilio (Springer Verlag, 2003)
      Our research is focussed on keeping both local and PVM jobs together in a time-sharing Network Of Workstations (NOW) and efficiently scheduling them by means of dynamic coscheduling mechanisms. In this framework, we ...
    • 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 ...
    • Predictive Coscheduling Implementation in a non-dedicated Linux Cluster 

      Solsona Tehàs, Francesc; Giné, Francesc; Hernandez, Porfidio; Luque, Emilio (Springer Verlag, 2001)
      Our research is focussed on keeping both local and parallel jobs together in a non-dedicated cluster or NOW (Network Of Workstations) and efficiently scheduling them by means of coscheduling mechanisms. A real implementation ...
    • Providing VCR in a Distributed Client Collaborative Multicast Video Delivery Scheme 

      Yang, X. Y.; Hernández, P.; Cores Prado, Fernando; Ripoll, A.; Suppi, Remo; Luque, Emilio (Springer Verlag, 2006)
      In order to design a high scalable video delivery technology for VoD systems, two representative solutions have been developed: multicast and P2P. Each of them has limitations when it has to implement VCR interactions ...
    • Supporting Caching and Mirroring in Distributed Video-on-Demand Architectures 

      Yang, X. Y.; Cores Prado, Fernando; Ripoll, A.; Hernandez, Porfidio; Qazzaz, Bahjat; Suppi, Remo; Luque, Emilio (Springer Verlag, 2004)
      Distributed Video-on-Demand (DVoD) systems are proposed as a solution to the limited streaming capacity and null scalability of centralized systems. In such full decentralized architectures with storage constraints, ...
    • Using On-the-Fly Simulation for Estimating the Turnaround Time on Non-dedicated Clusters 

      Hanzich, Mauricio; Lérida Monsó, Josep Lluís; Torchinsky, Matias; Giné, Francesc; Hernández Budé, Porfidio; Luque, Emilio (Springer Verlag, 2006)
      The computation capacity of the workstations of an open laboratory in almost every university is enough to execute not only the local workload but some distributed computation. Unfortunately, the local workload introduces ...
