Multiprogramming Level of PVM Jobs in a Non-dedicated Linux NOW
MetadataShow full item record
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 study the sensitivity of PVM jobs to multiprogramming. According to the results obtained, we propose a new extension of the dynamic coscheduling technique, named Cooperating Coscheduling. Its feasibility is shown experimentally in a PVM-Linux cluster.
