APPARATUS AND METHOD FOR RESOURCE ALLOCATION IN CLUSTERED COMPUTING ENVIRONMENT

摘要

An apparatus for resource allocation in a clustered computing environment includes: a node search unit configured to search for a node corresponding to necessary resources required for running a job requested by a user, within an available resource group of the clustered computing environment; a node existence determination unit configured to determine whether or not there exists a node having the necessary resources available; and a resource changing unit configured to change at least one of the necessary resources to alternative resources based on a preset priority and then allocate the alternative resource, when it is determined that there is no node having the necessary resources available.
