Abstract

Various embodiments include methods and devices for identifying core threads of a program executing by a processor. Some embodiments may include hooking an event by a kernel interface, calculating a total time cost for executing a thread of the program based on hooking the event by the kernel interface, returning the total time cost for executing the thread and a thread identifier of the thread to a core thread identifier program by the kernel, and determining a core thread of the program based on the total time cost for executing the thread and the thread identifier of the thread by the core thread identifier program.
