Formulas:
GPU memory utilization = 100*max(ROCP_TA_TA_BUSY,16)/ROCP_GRBM_GUI_ACTIVE/ROCP_SE_NUM
--
The percentage of GPUTime the memory unit is active. The result includes 
the stall time (MemUnitStalled). This is measured with all extra fetches 
and writes and any cache or memory effects taken into account. 
Value range: 0% to 100% (fetch-bound).
