1Executable files do not have data and instruction caches. – Ian Abbott Jan 20 '17 at 10:31

I meant when running the executable file – Yasser Nezzari Jan 20 '17 at 10:36

I imagine the caches will be full most of the time. – Ian Abbott Jan 20 '17 at 10:39

are you saying 100% of dcaches and icaches are used? is there a tool to see this ? – Yasser Nezzari Jan 20 '17 at 10:42

Unless something has flushed the caches recently they would normally be full unless the processor is enters a tight loop before the caches fill up. – Ian Abbott Jan 20 '17 at 16:50

1You may be able to use [Cachegrind](http://valgrind.org/docs/manual/cg-manual.html) on your program. – Ian Abbott Jan 20 '17 at 16:56
