Efficient hardware dispatching of concurrent functions in multicore processors, and related processor systems, methods, and computer-readable media

Abstract

Embodiments of the disclosure provide efficient hardware dispatching of concurrent functions in multicore processors, and related processor systems, methods, and computer-readable media. In one embodiment, a first instruction indicating an operation requesting a concurrent transfer of program control is detected in a first hardware thread of a multicore processor. A request for the concurrent transfer of program control is enqueued in a hardware first-in-first-out (FIFO) queue. A second instruction indicating an operation dispatching the request for the concurrent transfer of program control in the hardware FIFO queue is detected in a second hardware thread of the multicore processor. The request for the concurrent transfer of program control is dequeued from the hardware FIFO queue, and the concurrent transfer of program control is executed in the second hardware thread. In this manner, functions may be efficiently and concurrently dispatched in context of multiple hardware threads, while minimizing contention management overhead.

Problems solved by technology

Because functions can be relatively small units of computation, the management overhead incurred by contention management can quickly outweigh the realized benefits of parallel execution of functions
