Abstract: According to embodiments of the disclosure, methods, systems, and computer program products are disclosed. A computer implemented method of allocating resources in a job scheduling system may include segmenting a workload plan into one or more time slots, determining, prior to each time slot, a job forecast for the time slot, the job forecast based on historical job data, and modifying the resource pool to bring a resource pool parameter within a resource range in response to determining that the job forecast exceeds a job deadline. The workload plan may have one or more jobs for a resource pool, the one or more jobs may be scheduled in at least one of the time slots. The resource pool may have one or more resources.

Abstract: A computer implemented method, system, and/or computer program product selects a target computer to execute a job. For each computer in a system, a statistical mean of last job duration values is computed from historical records for all computers that have executed the job. Multiple pools of computers are selected based on a statistical mean of last job duration values. A ratio for each pool from the multiple pools is computed. This ratio is a ratio of the quantity of current executions of the job in a particular pool compared to a total of current job executions of the job in all of the multiple pools of computers. A particular pool of computers, which has a computed ratio that is closest to a preselected ratio, is selected. A target computer is selected from the particular pool of computers to execute a next iteration of the job.
