    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 ...
  • Executing algorithms with hypercube topology on torus multicomputers 

    González Colás, Antonio María; Valero García, Miguel; Díaz de Cerio Ripalda, Luis Manuel (1995-08)
    Article
    Accés obert
    Many parallel algorithms use hypercubes as the communication topology among their processes. When such algorithms are executed on hypercube multicomputers the communication cost is kept minimum since processes can be ...
