Abstract

In a distributed heterogeneous computer system having a plurality of computer nodes each operatively connected through a network interface to a network to provide for communications and transfers of data between the nodes and wherein the nodes each have a queue for containing jobs to be performed, an improvement for dynamically reallocating the system's resources for optimized job performance. There is first logic at each node for dynamically and periodically calculating and saving a workload value as a function of the number of jobs on the node's queue. Second logic is provided at each node for transfering the node's workload value to other nodes on the network at the request of the other nodes. Finally, there is third logic at each node operable at the completion of each job. The third logic includes, logic for checking the node's own workload value, logic for polling all the other nodes for their workload value if the checking node's workload value is below a preestablished value indicating the node as being underutilized and available to do more jobs, logic for checking the workload values of the other nodes as received, and logic for transfering a job from the queue of the other of the nodes having the highest workload value over a preestablished value indicating the other of the nodes as being overburdened and requiring job relief to the que of the checking node. The third logic is also operable periodically when the node is idle.
