Abstract
A workload scheduler supporting an efficient distribution and balancing of the workload is proposed. The scheduler maintains (383-386) a profile for each job; the profile (build using statistics of previous executions of the job) defines an estimated usage of different resources of the system by the job. The scheduler tends to select (318-342) the jobs with complementary resource requirements (according to a combination of their attributes); this process can be carried out using either a heuristic approach (318-334) or an optimization approach (335-342). As a result, the jobs that will be submitted are very likely to consume different resources of the system; in this way, any contention for the different resources is strongly reduced.
