Question on loads, stores and LLC miss count in Memory Access

Hi, all.

I have been trying to profile memory access of an application using VTune.

And I have the following questions about loads, stores and LLC miss count.

 

1. Does load and store count represents loads/stores that occurred in LLC only? or does it counts every single load and store in L1, L2 and LLC?

 

2. I think LLC miss count should be the same with the DRAM access count, but what I got is DRAM access count is larger than LLC miss count. What would make this situation?

 

I attached the images for each question. 

Thanks for answering in advance.
