Acceleration threads on idle OS-visible thread execution units

A processor comprising:

• a plurality of operating system-managed sequencers to each execute a thread;
• and
• an acceleration unit to
• detect when an operating system-managed sequencer of the plurality of operating system-managed sequencers is idle in an operating system;
• fetch an acceleration thread from an acceleration thread task queue, wherein a thread to benefit from accelerated execution is to place a pending acceleration thread into the acceleration thread task queue;
• execute the acceleration thread on the operating system-managed sequencer while idle and without intervention of the operating system, wherein the acceleration thread is to execute one or more tasks to accelerate execution of other threads to be executed on other operating system-managed sequencers;
• and
• return to an operating system-directed activity when there are no acceleration threads pending in the acceleration thread task queue.

A method comprising:

• detecting when an operating system-managed sequencer of a plurality of operating system-managed sequencers each executing a thread becomes idle in an operating system;
• fetching an acceleration thread from an acceleration thread task queue, wherein a thread to benefit from accelerated execution is to place a pending acceleration thread into the acceleration thread task queue;
• executing the acceleration thread on the operating system-managed sequencer while idle and without intervention of the operating system, wherein the acceleration thread is to execute one or more tasks to accelerate execution of other threads to be executed on other operating system-managed sequencers;
• detecting when the operating system-managed sequencer is demanded again by the operating system;
• and
• dropping execution of the acceleration thread when the operating system-managed sequencer is demanded again by the operating system.

• and
• returning to an operating system-directed activity when there are no acceleration threads pending in the acceleration thread task queue.
