摘要：
In a method for scheduling instructions executed in a computer system including a processor and a memory subsystem, pipeline latencies and resource utilization are measured by sampling hardware while the instructions are executing. The instructions are then scheduled according to the measured latencies and resource utilizations using an instruction scheduler.
