Abstract

A warp scheduling method includes: storing multiple first warps issued to a streaming multiprocessor in an instruction buffer module; marking multiple second warps which are able to be scheduled in the first warps by a schedulable warp indication window, wherein the number of the marked second warps is the size of the schedulable warp indication window; sampling a load/store unit stall cycle in each time interval to obtain a load/store unit stall cycle proportion; comparing the load/store unit stall cycle proportion with a stall cycle threshold value, and adjusting the size of the schedulable warp indication window and determining the second warps according to the comparison result; and issuing the second warps from the instruction buffer module to a processing module for execution.
