Implementing Explicit and Implicit Coscheduling in a PVM Environment
MetadataShow full item record
Our efforts are directed towards the understanding of the coscheduling mechanism in a NOW system when a parallel job is executed with local workloads, balancing parallel efficiency against the local interactive response. Explicit and implicit coscheduling techniques in a PVM-Linux NOW (or cluster) has been implemented. Their performance and overheads executing local tasks and representative distributed benchmarks have been analyzed and compared.

Solsona Tehàs, Francesc; Giné, Francesc; Molina, Fermín; Hernandez, Porfidio; Luque, Emilio (Springer Verlag, 2001)Networks of workstations (NOWs) 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 ...
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 ...
