For more complete information about compiler optimizations, see our Optimization Notice.

To get the CPU_CLK_UNHALTED event count, you will need to  run a VTune analysis on the coprocessor. You may choose to run a lightweight hotspot analysis on the coprocessor which collects the CPU_CLK_UNHALTED by default or could run a custom analysis. A good place to start would be: software.intel.com/mic-developer > Training Tab > Tutorials.

You can also check the following links for more information:

papi also has been ported to run under gcc only.  I haven 't seen any MIC specific tutorial.

the kernel support should be in the latest MPSS.
