A technique for job distribution within a grid environment includes receiving jobs at a submission cluster for distribution of the jobs to at least one of a plurality of execution clusters where each execution cluster includes one or more execution hosts. Resource attributes are determined corresponding to each execution host of the execution clusters. Resource requirements are determined for the job and candidate execution clusters are identified for processing the job based on the resource attributes of the execution hosts and the resource requirements of the job. An optimum execution cluster is selected from the candidate execution clusters for allocating the job thereto for execution of the job based on a weighting factor applied to select resources of the respective execution clusters.
