During profiling of a OpenCL kernel, I saw that "ALU Utilization" is 128%. I am curious that what this number signifies. IMO it should be 100% max.

What is the formula to compute "ALU Utilization" ? Please guide me to the link which explains these matric parameters.

 

Thanks in advance!!

You are right, the % ALU Utilization should not go over 100%, the metric calculation depends on the Adreno GPU you are using. What device are you using?
