Abstract
An operating system interface, responsive to detecting a non-privileged thread request with a scheduling attribute set to a critical setting to request access to at least one privileged core, selectively schedules the non-privileged thread request into a privileged core queue associated with the at least one privileged core only when a resource availability of the at least one privileged class core meets a threshold level of availability, the at least one privileged core providing a higher throughput than at least one regular core. The operating system interface, responsive to detecting a privileged thread request with the scheduling attribute set to the critical setting, automatically scheduling the privileged thread request into the privileged core queue.
