A method for scheduling a thread on a plurality of processors that includes obtaining a first state of a first processor in the plurality of processors and a second state of a second processor in the plurality of processors, wherein the thread is last executed on the first processor, and wherein the first state of the first processor includes the state of a cache of the first processor, obtaining a first estimated instruction rate to execute the thread on the first processor using an estimated instruction rate function and the first state, obtaining a first estimated global throughput for executing the thread on the first processor using the first estimated instruction rate and the second state, obtaining a second estimated global throughput for executing the thread on the second processor using the second state, comparing the first estimated global throughput with the second estimated global throughput to obtain a comparison result, and executing the thread, based on the comparison result, on one selected from a group consisting of the first processor and the second processor, wherein the thread performs an operation on one of the plurality of processors.
