Abstract
Disclosed are embodiments of a system, methods and mechanism for using idle thread units to perform acceleration threads that are transparent to the operating system. When the operating system scheduler has no work to schedule on the idle thread units, the operating system may issue a halt or monitor/mwait or other instruction to place the thread unit into an idle state. While the thread unit is idle, from the operating system perspective, the thread unit may be utilized to perform speculative acceleration threads in order to accelerate threads running on non-idle thread units. The context of the idle thread unit is saved prior to execution of the acceleration thread and is restored when the operating system requires use of the thread unit. The acceleration threads are transparent to the operating system. Other embodiments are also described and claimed.
