Thanks Fernando for the information. So from what I can infer, this will dump stats whenever there will be any kind of context switches. I am assuming that for 1 core run, only two types of context will be running, user mode and kernel mode. So will it be mean that every alternate stat prints will be of the user mode? Or is there any other way to link the stats with the mode?
Thanks for your time.
