Abstract
Systems and methods for scheduling jobs in a multiprocessor machine are disclosed. The status of resources in the multiprocessor machine is periodically determined. The status indicates the resources available to execute jobs. This information is accumulated by the topology-monitoring unit and provided to the topology library. The topology library also receives a candidate host list which lists all resources available to execute the job being scheduled based on non-trivial scheduling. The topology library unit generates a free map F indicating the interconnection of the resources available to execute the job. The topology monitoring unit matches jobs to the resources available to execute the jobs, based on resource requirements including shape requirements indicative of interconnections of resources required to execute the job. The topology monitoring unit dispatches the job to the portion of the free map F which matches the shape requirements of the job.
