Abstract: In an approach to optimizing dynamic system reconfiguration, a computer receives an active system configuration and a target system configuration from a system administrator, where the target system configuration includes two or more logical partitions. A computer determines one or more reconfiguration actions required to transform the active system configuration to the target system configuration. A computer generates a dependency graph based on the determined reconfiguration actions. A computer divides the dependency graph along the two or more logical partitions. A computer sorts the determined reconfiguration actions by associated dependencies. A computer orders the determined reconfiguration actions based on a priority of each of the two or more logical partitions. A computer runs a first simulation of the determined reconfiguration actions for each of the two or more logical partitions. A computer performs the determined reconfiguration actions for each of the two or more logical partitions.

Abstract: A method, computer system, and a computer program for managing computer jobs in a queue is provided. This comprises extracting metadata from a new job received for processing and upon determining when a similar enriched metadata exists in a database. A job score and storage footprint may then be determined for the new job from the extracted metadata. It is then determined whether the new job can be grouped for processing with any other jobs already placed on a queue. The new job is then added to the queue based on the new job's score and footprint, and whether it can be grouped with other jobs. The queue is then updated and sent to a scheduler for further processing.

Abstract: A computer system may initialize one or more workloads. The computer system may operate in a boost mode and a regular mode. The boost mode may include an adjustment of a pacing setting and an adjustment of group availability targets for executing the one or more workloads. The computer system may identify that the boost mode is enabled during a system start of the computer system. The computer system may identify that the pacing setting is operating in the regular mode. The computer system may dynamically increase the pacing setting. The increase of the pacing setting may enable an increased processor utilization of the computer system by the one or more workloads. The increased processor utilization may generate a concurrent processing of the one or more workloads. The computer system may determine an end of the boost mode and reset the pacing setting.

Abstract: Performance predictions in a computing cluster can be provided by sampling and storing historic workload request data of the computing cluster as time-stamped workload values, forecasting an expected total number of workload requests for a defined time interval in the future based on a time-series analysis of the time-stamped workload values, where the time-series analysis detects cyclic and repeating events in the time-stamped workload values. In response to a result of the time-series analysis, training a workload prediction model by using additional data about acyclic events in expected workload requests, where the training applies a statistical regression technique for predicting a future workload demand for the computing cluster, and in response to exceeding a predefined threshold value of the predicted future workload demand, reassigning resources of the computing cluster.
