It looks the traceX only only show kernel activities from one core as I was reading the chart produced by the traceX since every event is in sequential in timely manner. Shouldn't there be some overlap if it can dispaly the activities of multi cores? There may also exist possibility that I do not figure it in right way. Thanks in advance for your help.
I was trying to search the right tag requested below but I failed to get traceX or threadX which look more relevent.
