Assume that in Julia I have the following, which I assume should be OK because arrays in Julia are column major. x = Array{Float32, 3}(500, 20, 200) # Initialize x for c = 1:200 for b = 1:20 for a = 1:500 x[a, b, c] = x[a, b, c] + 1 end end end Now, if I want to…

Is the above code optimal Well, you can just benchmark it, right? Given this slightly modified example which allows me to quickly shift indexes around (with the 1024 thread limit of my GPU): function kernel(x) c = blockIdx().x b = blockIdx().y a = threadIdx().x x[a, b, c] = x[a,…

Sorry to necro-bump this thread but did anyone get anywhere with a GPU friendly sorting algorithm?
