Compare the time used for convolution between CUDA and CPU

Compare the time used for convolution

TASK

Input a image named "test.jpg" and do convolution with a 3×3 kernel like this:

| -1 -1 -1 |
| -1 8 -1 |
| -1 -1 -1 |

COMPARE

cpu cpu_openMP cuda cuda_constant cuda_texture cuda_texture_2d cuda_texture_constant

RESULT

1. CUDA is FASTER than CPU
2. cuda_texture_constant is the FASTEST
3. image size dosen't slow down the speed of the CUDA
4. Ubuntu is faster than Windows(I have a PC installed Windows and Ubuntu at the same time)
5. openMP is useful when you have no CUDA.

For more information,please refer to the data_and_figure.xlsx

Some Result Figure

Ubuntu's performance on two images

CPU and openMP

cpu_cuda_compare's Issues

How faster does ubuntu handle speed than windows

Could you share the ubuntu'time and windows's time?
