How can I verify that my model was properly quantized with int8 instructions? Are there something stored or logged for me to check? I collected profile and run model in OpenCL mode and did not see significant performance difference. I use Pascal 1050 Ti  which is 6.1 compute compatible device which must support efficient Int8 vector dot product operation (d4pa??). I clearly see GPU boost over CPU backend but almost no quanitization caused speedup. What is the trick?
