Method for managing a processor, lock contention management apparatus, and computer system

摘要

A method for managing a processor includes: obtaining an online request of a processor of a computer system; collecting lock contention information of the computer system if a lock contention status flag indicates a non-lock thrashing status; determining whether the computer system is in a lock thrashing status according to the lock contention information; and accepting the online request if it is determined that the computer system is in a non-lock thrashing status. By using the management method according to embodiments of the present application, processor performance degradation and a waste of idle processor resources that are caused by the case that the computer system is in a lock thrashing status are prevented, thereby improving utilization efficiency of processor resources and promoting overall performance of the computer system.
