Abstract
A system, method and computer program product for managing computer resources in a computer system running an operating system and a plurality of processes grouped into at least two groups. A set of resource limits corresponds to the processes. A scheduler of resource allocation allocates resources to each process such that total resource allocation to a group to which that process belongs remains constant. The resources comprise, e.g., network bandwidth, number of network connections, I/O bandwidth for peripheral devices, number of operations in a period of time for service operation with countable requests for service, number of operations in a period of time for a daemon with countable requests for service, permission for execution of operation, number of security descriptors, and number of terminals. The scheduler reallocates the resources based on a predictive algorithm, or based on process priority, or based on relative weighting of the processes. The scheduler can adjust an increase and a decrease of the resources available to a particular process. The scheduler is capable of increasing a resource allocation restriction to one process by and by waiting for that resource to become available. The scheduler is capable of increasing a resource allocation to one process by reducing allocation restriction to other processes in the same group on a basis proportional to their current use of that resource. The scheduler can reduce a resource allocation to a particular process based on a history of consumption of the resource by that process and a history of consumption of other resources by that process.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
