Active Time (ms) = Stall Time (ms) + Active Utilization Time (ms).

Take tile(6,0) as an example, tile(6,0) is active for a period of 1.401 milliseconds, where 1.333 milliseconds is stalled and 0.069 milliseconds is actively executing instructions. During 0.069 milliseconds active period, 0.061 milliseconds is executing vector instructions. There are 0.008 milliseconds spent on other instructions such as load/store instructions.

There are 76800 Vector instructions, 79303 Load Instructions and 1135 Store Instructions during Active Utilization Time (ms).
