I am trying to apply a kernel function on a__device__variable, which, according to the specs, resides "in global memory" #include<stdio.h>#include"sys_data.h"#include"my_helper.cuh"#include"helper_cuda.h"#include<cuda_runtime.h>doubleX[10] = {1,-2,3,-4,5,-6,7,-8,9,-10...
This removes both the extra copy before and after the kernel run. We just used output as temp and used input as write back as we are using a separable filter. The "output.set_final_ptr(output_img_ptr);" gives a compiler error for us. But it was not needed in this case. Contributor...
