By default the `STANDARD_DATASET` as defined in the `.cuh/.h` file is used as the input size. The dataset choice can be adjusted from `STANDARD_DATASET` to other By default the `STANDARD_DATASET` as defined in the `.cuh/.h` file is used as the input size.

the input size can be changed by simply adjusting the `STANDARD_DATASET` so the program has different input dimensions. the input size can be changed by simply adjusting the `STANDARD_DATASET` so the program has different input dimensions.
###`DATA_TYPE` (in `.cuh/.h` files): #### `DATA_TYPE` (in `.cuh/.h` files):
By default, the `DATA_TYPE` used in these codes are `float` that can be changed to `double` by changing the `DATA_TYPE` typedef. Note that in OpenCL, the `DATA_TYPE` needs to be changed in both the .h and .cl files, as the .cl files contain the kernel code and is compiled separately at run-time.
