Scheduling threads on different processor cores based on memory temperature

摘要

Techniques for scheduling a thread running in a computer system are disclosed. Example computer systems may include but are not limited to a multiprocessor having first and second cores, an operating system, and a memory bank for storing data. The example methods may include but are not limited to measuring a temperature of the memory bank and determining whether the thread includes a request for data stored in the memory bank, if the temperature of the memory bank exceeds a predetermined temperature. The methods may further include but are not limited to slowing down the execution of the thread upon determining if the thread includes a request for data.

1. A method of scheduling execution of a thread in a computer system, the method comprising:
receiving a request to execute the thread; scheduling the thread to be executed according to a first schedule on a first core; obtaining a measurement of a temperature of a memory bank in the computer system; determining whether the temperature of the memory bank exceeds a threshold temperature; determining whether the thread includes a request for data stored in the memory bank; and in response to the determination that the temperature of the memory bank exceeds the threshold temperature and in response to the determination that the thread includes a request for data stored in the memory bank, scheduling execution of the thread on a second core different from the first core and according to a second schedule with a delayed execution for the thread relative to the first schedule.
