Abstract: A system and method is provided for dynamic renewable runtime resource management in response to flexible resource allocations by a processor. In embodiments, a method includes: calculating, by a processor of a system, a resource consumption value of a first workload by aggregating allocation values of persistent resources currently allocated to the first workload by the processor; determining, by the processor, that the resource consumption value of the first workload is greater than a predefined resource allocation target for the first workload; and temporarily adjusting, by the processor, a renewable runtime resource target of the first workload from an initial target value to a temporary target value based on the resource consumption value.

Abstract: Predictive job admission control is provided. In response receiving a job for execution, a predicted resource utilization estimate is generated for the job prior to admission of the job to execution. Historic job execution statistics corresponding to the job are searched for. It is determined whether corresponding historic job execution statistics were found during the search. In response to determining that corresponding historic job execution statistics were found during the search, the predicted resource utilization estimate for the job is adjusted based on the corresponding historic job execution statistics found during the search to form an adjusted resource utilization estimate. The job is scheduled for execution based on the adjusted resource utilization estimate.

Abstract: According to an embodiment of the present invention, a system assigns at least one workload a hard share quantity and at least one other workload a soft share quantity or a hard share quantity. The system allocates a resource to the workloads based on the hard share quantity and the soft share quantity of active workloads in a predefined interval. A hard share quantity indicates a maximum resource allocation and a soft share quantity enables allocation of additional available processor time. Embodiments of the present invention further include a method and computer program product for allocating a resource to workloads in substantially the same manner as described above.
