A basic question about unguided utilization analysis


I saw a NVIDIA presentation slides: http://on-demand.gputechconf.com/gtc/2013/webinar/gtc-express-guided-analysis-nvidia-visual-profiler.pdf

For the slide of 4th page, the kernel is memory bounded, the right column shows a high utilization of device memory.

I wish to know what is the memory operation part in the left column mean, what is included in this part?


This is just a guess, but perhaps it’s referring to on-chip memory operations such as shared loads and stores.
