I want to make sample code to see effect of transaction elimination so I made 2 experiments
1- running the kernel 10 times to write same data on frame buffer and record time of each running.
2- running the kernel 10 times to write random data send by send uniform variable with random data and record time of each running.
when I comparing the time is still in the same range I expect that time for write same data will be less than time of random data due to transaction elimination but it didn't happen.
My question how I can see effect of transaction elimination? I used Galaxy S6 GPU T760 MP8
